Latest Changes to Part L Building Regulations from ARC Building Solutions
Do you know about the latest changes to Part L Building Regulations?
The changes are part of the Government's step toward its target to deliver Zero Carbon Ready Homes by 2025.
From 15th June 2022, all new homes must produce 31% less CO2 emissions than what is currently acceptable in the present Part L regulations. Therefore, the construction of new dwellings must comply with the increased energy performance standards as set in the new regulations.
An on-site audit will be required to confirm that the designed details have been constructed, and photographs must be taken as evidence to form the BREL report.
What is Thermal Bridging? Why is it a concern for CO2 emissions?
A “thermal bridge” (also known as a “cold bridge”) is a disruption in a building’s thermal wrapping, such as a gap in insulation. Thermal bridging causes heat loss and condensation. Heat loss has a significant impact on the energy efficiency of a building, making this a crucial problem to target to reduce CO2 emissions.
How can Thermal Bridging be reduced?
Insulation must be continuous. This applies to areas such as walls, roofs, windows & doors, and the junctions between these areas. For example: Roof insulation should be continuous with wall insulation. The regulations advise that “opportunities should be considered to use products that help to reduce thermal bridges”.

I do EPC surveys on commercial buildings. Often tasked to do these out of hours, i.e. when the occupants have gone home. For example, I did one the other day on an adult education centre. I was told to go at 4pm when classes had ended. Nearly every room used for classes had the A/C running with nobody in the room. Each of these rooms had local controls for the A/C able to be adjusted by any old Tom, Dick or Harry. I turned them all off on my route. I get to go to loads of these types of buildings and shake my head at how they are managed. Sorting out controls, who can adjust them, setting up responsibility for building managers, central BMS systems ONLY and accountability is more important. The issue is occupants do not give a shit because it isn't their electricity, isn't their building and isn't their responsibility. Clown world.

Sometimes building managers say to me we cannot fix the system because the people that can are from another country or company gone bankrupt.

Good builders get a good reputation and typically don’t need to advertise, they get more than enough work by word of mouth. When choosing a builder, if you can’t get a recommendation from someone you trust then you need to see examples of work they have recently completed and speak to their customers. If they can start work immediately then be suspicious, if they are the cheapest then be suspicious. It’s not rocket science.

In thirty years time it'll turn out that manufacturing all that insulation was terrible for the environment and/or made by firms that had links to senior government officials. 😏

[@scottm4193]

100 percent. PIR insulation has maaaasive amounts of embodied carbon because of the high temperatures needed during its manufacture. Continually adding more and more insulation in buildings doesn't necessarily mean lower carbon emissions overall it can actually lead to more if you look at lifetime emissions. But since there's no inclusion of calculating embodied carbon in the new regs this has been swept under the rug. Madness.

Continually adding more and more insulation in buildings doesn't necessarily mean lower carbon emissions overall it can actually lead to more if you look at lifetime emissions. PIR insulation for example has maaaasive amounts of embodied carbon because of the high temperatures needed during its manufacture. And guess what produces those high temps? Fossil fuels. But since there's no inclusion of calculating embodied carbon in the new regs this isn't evident. And instead we get homes with smaller internal volumes and for higher costs!

[@nervousfrog101]

Luckily we are de-carbonising industry as well. PUR panels are produced at around 40-45ºC with no primer; PIR panels need temperatures of around 60 to 65ºC and a primer. These temps are easily achievable using renewable energy. For example Celotex manufacturing plants are certified to ISO 14001, ISO 50001 and ISO 9001: 2008 and use 0% CO2 electricity.

[@smartbuildengineering]

Great information, thanks Roger! Having spent quite a bit of time in Sweden where high insulation, triple glazing, heat pump heating and good air tightness and mechanical ventilation are standard, I can confirm those houses are much nicer to live in. We might not need the same levels of insulation for our climate, but we have plenty of room for improvement so I think raising the standards is a good thing. The way the Swedes deal with waterproofing in their bathrooms is also very interesting - baths are never sealed to the wall, instead all bathrooms are fully wet-roomed, the bath is dry butted against the tiled wall and there is a gulley under the bath with appropriate floor falls. Any water that hits the wall and flows down past the bath just flows along the floor into the gulley. The waste from the the bath is just a stub of pipe directed into the gulley. They've effectively designed out the common failure point that is the bath-wall mastic seal.

[@sichere]

The weather conditions are totally different in Sweden than the UK. In the 1950's The Ministry of Public Works copied many of the Swedish timber frame designs but found that they would be expensive and opted for single glazing, less insulation, and other cost cutting methods to suit the British climate, resulting in thousands of families living in properties that were basically not fit for human habitation.

[@nobodydoesithalfasgoodasyou]

Much as I DESPISE doing the caulking around a bath, I would really rather the hairs and grease and soap scum stayed on top of the bath whence they can be washed away. Also, a freestanding bath needs to be a lot sturdier than one that is stuck to the wall on two or three edges. I have no issues with a nice thick steel bath but that extra weight is extra thermal mass which is extra money down the drain (or...not) every time you have a soak.

[@mypointofview1111]

My personal view is that many of the measures being mandated will lead to rot and decay in many British housing. The only way to get round this is to demolish areas of poor housing and build decent housing in it's place. The comment by Sichere that adoption of Swedish housing standards was abandoned in the 1950s is a prime example of cost cutting and poor management by government of the day. As only 2% of the land in the UK is used for housing there is scope for more homes to be built. There's also the argument that the Royal family needs to relinquish more of its lands, does one very rich family need to occupy 70% of the landmass in the UK? Do they think the great unwashed are just going to conduct raids and attack them willy nilly? That mindset says more about them than about us, but I digress. Patching up problems in existing houses is prohibitively expensive on top of the cost of housing at today's prices. There's an argument for doing away with a lot of Victorian, Georgian and older housing that falls way below the standards we are trying to obtain. This will be costly in itself as people will have to be rehoused or adequately compensated. People will also need to be educated on how to live in these new buildings, as at present some of my own neighbours don't bother opening their windows in the summer to allow proper ventilation and then complain of damp in winter. People need and deserve better housing than they currently have, just continuing as before because its always been like this just isn't an option

[@sichere]

@@mypointofview1111 You're spot on but it'll never happen. Drive down any road in the UK and imagine how many houses need new kitchens Bathrooms Windows or a complete overhaul. Maintenance is often neglected as a low priority but in many cases it now cost more to fit a Bathroom to an old Georgian or Victorian house than it did to build it originally

[@cheeseburgerbeefcake]

It's about damn time nuclear energy is being accepted again! Trickle vents are the cheap alternative, but it really does feel counter intuitive to have huge amounts of insulation, then to open vents and let the cold in; but the cost of a heat recovery system is enormous in comparison. I completely agree about the documentation side - every installation will be like gathering evidence for a C&G qualification, while not a bad idea to prove the job is done right - a MASSIVE cost to burden the customer with.

[@Tom_Hadler]

Exactly. Mandatory hermetically sealed insulation and mandatory trickle vents on new windows. Thus proving the perfectly gapless insulation standard to be pointless

[@kissarmy1347]

I hope this applies to the people who do EPCs as well. We spent lockdown renovating a property to rent out and tried our best to put as much insulation in as possible when framing out the walls. We took detailed photos of everything - hundreds of them. When we got the EPC done we were informed that photographic evidence was not acceptable and they could only include things they could see unless we let them open up all - and they meant all - the freshly decorated walls. We are now saddled with an EPC rating of a low D which should be a high C.

Whoever told you that isn’t right. If photographic and documentary evidence can be provided you absolutely can put that into the epc. I ask for photos of the insulation fitted and a photo of the room (so you can see the photos apply to that property). You can either ask the assessor to re do it or get another assessor who knows what they’re doing to give you the proper rating

[@kissarmy1347]

@David Handley Thank you for that. I think I will get a different assessor. I won't name him but he was most insistent that his accrediting body would not increase the EPC level based on us submitting photographic evidence. After all the work we put in to the insulation I was very disappointed to only get a D rating.

I like the idea of adopting the Swedish housing standards in the UK, I think it's long overdue. However my main gripe is the open plan interiors, I hate them, they don't work. It's very rare that even in a 2 person household everyone will want to do the same thing at the same time. One will want to do some work, another will want to talk to friends on the phone or virtually, if there's more people someone will want to watch tv, another will want to read or listen to music. If you add kids into the mix they'll want to play somewhere. There's a reason why we have rooms with doors, so there's some separation, somewhere you can do what you need to do without having to be in your bedroom. In this respect the late Victorian houses got things right, particularly those that are double fronted. Each person can have their space and you can still have a lounge to relax or entertain. We need to understand that our need for our own space is still vital to function in our lives

[@karlphillips3259]

Open living sounds good but doesn't provide enough soundproofing (sounds echo around the whole house), smells and oils will circulate through the whole house (fish, eggs, toilets), it means you have the heat the whole house and not just the rooms you need at the time (different parts of the house need to be heated to different temperatures, especially the bedrooms); privacy when you are hosting or have guests is less available, and these days when lots of people are home working there are a lot more disruptions. We seem to going backwards and not learning from what our Victorian forbears learnt a long time ago. Houses need active, passive, shared, personal and quiet areas to be fully functional for all our needs.

We’ve all been brought up with the story of the three little pigs and wolf blowing down the house made of sticks. When I bought my triple glazed timber framed imported Swedish house 35 years ago friends joked about termites, they thought it would catch fire or rot away as quickly as a waney edged fence panel. As a result I got a complete bargain and went from huddling around an open fire to keep warm to a house where we can happily use every room at any time. On freezing cold winter mornings when the sky is usually clearest - sun streams through under the eaves and our heating stays off while the house is at >23C. I’m done with period features, fireplaces as a focal point, plasterboards, sash windows, trickle vents, steamed up windows, dripping condensation, draughty letterboxes, and stuffy rooms - it's unfortunate that the UK is still going to sleep with bedtime stories about straw houses.

I fully agree with the point about heat recovery ventilation. Fitted a few several years ago and the customers were delighted. A multi-room kit is easily fitted where there is a loft above and not very expensive.

If the insulation levels and overhangs are designed correctly they won't need to be cooled in anything but extreme summer but will be more energy efficient and cost effective in the winter. Sadly most of these proposals aren't drawn up by in field engineers, they're dreamed up by idealists that think our climate isn't already in need of air conditioning. The boat sailed, climate change happened already it's better to address it as is than pretend we're still a heating dominated climate.

My wood is cheaper, just as strong (given what it's doing) and will last just as long. *The original i removed was wood. As i widened the opening slightly, the original lintle was too small, 4 pieces of door frame stacked and screwed was 10 times as strong as the original.

In cavity wall construction why not construct the inner leaf using 200mm insulation block eg aircrete, and the outer leaf (which only serves to protect from the elements ) can remain at 100mm.The cavity ought to be preserved and ventilated using airbricks to ensure no moisture build up and hence dry walls. Surely this is a better solution and would be easier for the block/brick layer as the need for cavity insulation which is awkward and problematic can be eliminated. An insulation backed plaster board may be attached to the inner walls to further improve thermal insulation. That would be my solution as far as the walls are concerned.

[@nedmoulders4814]

Hit the nail on the head. I have recently had a number of clients opting for a rear garden room annex rather than an extension to their home. Either to use as a gym / workout room or an office due to the prevalence of working from home or setting up a personal business. These are usually built within 1M of a boundary and the Planning Regulations dictate a maximum height within the 1 M as 2.3M. If a flat roof is opted for then the whole annex at it's highest point will have to be 2.3M or less. But wait! The floor level is usually 150mm above ground level. Allow for the amount of insulation between joists and under joists given and allow for a 50mm air gap over the insulation - 400mm Allow for a 50mm titling piece to the higher edges of the flat roof and a 1:60 fall to the eaves (say) - 75mm Allow for the thickness of the roof covering and the ply decking (say) - 30mm Allow for the plasterboard ceiling - 12.5mm (excluding a 3mm skin coat and assume tape and joint finish). Total roof thickness in the region of 490mm. I'm guessing that leads to a ceiling height within the annex of around 1860mm ie. not enough and an external door height nigh on impossible to achieve. If a pitched roof (tiled) is chosen then the maximum height to the eaves is 2.3M and the maximum overall height is 4M. Even with a roofing tile that will achieve 17.5 degree pitch this is difficult to achieve leading to lowering the eaves height well below 2.3M in most cases. The above is predicated upon current Permitted Development allowances. The alternative is to apply for Planning Permission that in my experience in most cases will be refused. Or reduce the annex to more than 1 M from a boundary which for most of my clients would not provide an acceptable internal space. You can bet that the Permitted Development regulations will not be changed. NB the default position for most all of the Local Authority Planners is to look for reasons to refuse planning permission.

Took longer to do but I know it's going to work. Also insulating pipework in under floors and in voids makes perfect sense especially on low temperature, systems, what is the point in heating the void under the floor when the floor coverings above will act as insulation, you're just wasting heat that could be sent to a radiator in a useful location.

I think in a previous video you made a very good point that radiators do not actually radiate but are convection heaters and transfer heat to you using air. The hot air from your radiator becomes very precious and so yeah I can understand a reluctance to opening a vent and letting it out 🤣. However, if you have underfloor heating the transfer mechanism changes and the heat radiates to you directly. In fact if you heat the building constantly (albeit at a lower temp) every part of your house warms up becomes a source of heat that radiates. And then it's much less of a big deal to let out some hot air out and let in some cold air. Such a house can cope with the air change without you feeling like you are going to freeze.

As for heat pumps there’s an opportunity there to heat and ventilate at the same time sadly the boffs never take all the factors into account so for the majority of the year we have a westerly flow of air that has high humidity which makes it difficult to add our higher humidity air from our houses.

I'm sure they'll find a way to get around installation images they need to provide. I live in social housing but was in the building trade for many years. Every single job I've had done on my place has had to be done twice due to shoddy work or no knowledge of what materials they have to use for certain jobs. I just recently had them out to fix 2 leaks in a gutter. They took over a month to erect a scaffolding, it sat there for over 2 months when the scaffolding company came to take it away not realising the job hadn't even been done. They left it in place and a workman turned up a few weeks later and painted something on them and the scaffolding was also taken that day. £ days later it rained, and guess what? Yes the leaks were still present. This must have cost them a fortune. They lose so much money by not doing a job right in the first place it's ridiculous. The worst part is that they sometimes send out an inspector first and he tells you what is going to be done, only for the trades turning up asking you what's the problem and usually saying..."well we weren't told to do the other wall, so we're only doing one, take it or leave it , as happened with a problem i had with penetrating damp on an outrigger. Believe it or not, the wall they did do with dot n dab was flapping about after it was dry so another joker came along to screw it back to the wet wall. I'm having the same issue again, even with the new plasterboard wall. I explained to the inspector in the first place that the problem was with spalled brick, I even circled the damp patches inside and showed him the corresponding bricks outside because his first diagnosis was condensation, to which I explained that I don't even get that on my window, which is a good indication of a dew point. I've now got a brickie coming in a few days as I reported it again online as brickwork problem. They've recently done the walls below in the kitchen. They were sopping wet and the lad put some black paint on to act as a membrane barrier. I suppose it's a form of tanking but not? But to be honest, it didn't adhere to the failing mortar between the bricks, so I don't know if that will last. Anyhow I'm going to appeal to the brickie's good nature when he turns up and see if he'll do all the bricks on the outrigger, and even better repoint it all. I have no doubt he hasn't the authority to do this, but hopefully he will go back and say this fella has had enough of upevil and expense over our usual sticking plaster approach and that we do the job that needs doing.

I find it shocking that anyone would even consider retrofitting a heat pump in a older house that does not have modern standards of insulation, airtightness and ventilation. Heat recovery ventilation is well established and fairly inexpensive to install in a new house, and with the full package the heat pumps work well and are very efficient. Triple glazed windows are pretty much standard here now. Installing all the modern stuff in an existing house comes under the heading of a deep retrofit, there are large grants here available for deep retrofits but even with the large grants it’s still extremely expensive.

Regarding the costs and housing becoming more expensive. Homes will only cost what people can ultimately afford. The highest cost in almost every home is the plot of land. If the overall price of a house is limited by the market and the building itself becomes more expensive then land values will fall to take up the slack.

Of course, increasing the heat efficiency of the external walls can result in at least two physical possibilities: either the footprint of the building has to increase or, the size of the rooms has to decrease. You can bet developers will opt for the latter! Cynical? Maybe, but a developer in my region successfully persuaded the planners to allow narrower roads - vis-a-vis existing adjacent road system which it was extending, so that it could squeeze extra houses on the land; even going to the extent of reducing the footpath in at least two instances to just a single footpath along one side of the road. With the law now forbidding parking on pavements this results in an obstruction being created if vehicles park on each side of the road - even in the turnings with just a single footpath!

Great video! Same in Holland at this moment. It amazes me how our Dutch government is going to tackle this. QOUTE: Vanaf 2026 is een hybride warmtepomp verplicht bij de vervanging van de cv-ketel. Het kabinet hoopt op die manier minder afhankelijk te worden van aardgas. So, from 2026 on it is obligated (!) to have a heat-pump next to your new central heating device inststalled. Not one word about isolation or efficiency or temperature. Not one word! We do not have enough a/o skilled laborers to make this work and a lot of advantages will be taken from this (making money over stupid customers). What will happen in the long run?

[@Tom_Hadler]

Ground source heat pumps may be OK, but air source heat pumps are rubbish! Disgusting law. They want us to suffer, while they sell us heat pumps, overpriced insulation, and eventually; blankets

[@1966MrAlex]

If these insulation rules apply to the Netherlands, there are many houses that would be better off putting a bulldozer in front of them.

[@robwal3665]

At a time when these requirements are being forced on everyone all of a sudden insulation and building materials are more expensive than ever 🤔 It's all to make the rich richer

[@ricos1497]

It's not all of a sudden though, is it? It was supposed to be done by 2016, but the Tories scrapped it to appease their mates in the housebuilding industry. The rich won't get richer by lower fuel bills for the general public, hence why it's taken so long. The arse about tit approach to heat pumps and ventilation that Roger mentions is very likely a con to make people pay twice though.

[@TrickyTree84]

When do you suggest it happens? The more expensive materials won't go down in cost until mass adoption

Hi Roger, Thank you for you excellent work, great information and continued enthusiasm. I've enjoy it very much ! I have been in the refrigeration / air conditioning - Heat-pump industry all of my working life (over 40 years ) and for 33 years of this, I have been running my own successful AC company in the heart of Wiltshire. I would love to talk with you regarding air to air heat pump systems, as I am not a fan of air to water systems or many reasons including; they are over priced, far too complex and from my experience, the companies selling and installing these systems generally have NO idea how the heat pump actually works ( Which is a huge worry) hence why there as so many people being left with out heating for long periods of time! The skill set to repair these is just NOT there !!! I have just completed a 2 bedroom house within the grounds of my property, and this is heated via a SINGLE concealed air to air heat pump "HYPER" inverter system which draws less than 13amps when running ! Its a ducted system similar to the type found the States and I have been heating the Main house with two of these "Split" type AC systems for over 10 years now. 99% of the time its used in heating, only this year did we use the cooling side (which was a joy!) Please get in touch, as I'm sure my knowledge in the field of engineering would possibly be very useful to you. Best regards Neil Davison

I know this comment is way too late but Roger spoke of one word all the time and not mentioned once. Shambles! Everything about the UK can simply be described by that one word. Best intentions but always the same outcome!

[@1992jamo]

Hi Roger. This is a bit financially scary to be honest. How much do you think this will increase the cost of extending a ~30 year old building?

[@jamescaley9942]

Any new standard should be proven as practical with pilot builds. Engineering is compromise in search of perfection. If all the focus is on one thing - CO2 - that will likely lead to significant compromises elsewhere.

[@robertsmart7484]

Changes in Building Regulations take years to gestate as there are extensive consultations with the building industry and especially large volume housebuilders regarding practicality and cost, which always delays necessary changes. The "new" changes to the regulations probably started life 5 years ago.

I have just started my loft conversion so Part L will be key especially as main reason to do so was to try and retain heat in the house. Old 1920's house with high ceilings, single brick house and leaking heat everywhere. I am hoping the newly insulated loft will retain heat in the house however, I still have a lot to do. I still have to do something about the walls/windows and will look at EWI and newer glazing. I do worry that with houses so insulated, are they going to be able to breathe and in the summers, are they going to be hot. I am now looking at AirCon esp after the summer of 2022 and potentially, hot months being very common in the future. Great videos Roger - no building skills here but have learnt a lot from your videos.

[@skiathosmobi]

Excellent, excellent, excellent what a show!!! Thumb is obviously better, one layer t shirt....come on Roger tell it as it is......👍👍👍👍👍👍👍👍👍

[@evildiesel7850]

Thank god we are going to get our next app in by 15th June - not sure I would bother otherwise. Need to get footings in for all plots in 12 months and job done. Thinking this might be our last one on current trends - been doing an average of 15 plots a year since 2015. Probably for the best - starting to have all sorts of health issues (bad lifestyle choices I suppose) so it won't hurt to knock it on the head and just start a planning gain play.

[@toddbod94]

They really need to just bite the bullet and abandon radiators if they ultimately want to enforce heat pumps. Air to air systems work much better than air to water.

[@BrianSmith-ow9gy]

God, now you are really taking me back. I and many, many of my friends took out warm air underfloor heating systems and replaced them with gas boiler powered heating and hot water systems. Being forced back to warm air systems brings a cold chill to my heart. Next it will be Economy 7 systems. We all know how well they worked out.

[@bullshitsorry5734]

very well explained ! I'm a roofer, every day is a school day !!

[@endicous]

I will make one comment. This all should start long ago but with the education in schools so the public is fully aware how to look after and manage energy
