I'm a first timer doing a self build annex, I used Breckland Council. They did the initial visit when planning was first permitted. It was an informal chat, on site. They were really helpful and answered my questions, especially regarding deviations from the building plan and what can and can't be changed without amendments etc.
After each check I asked them what they wanted to see next. Booking inspections was really easy through their web portal. The first check was the foundation trenches, then drains, then DPC, then oversite with DPM before I poured the first slab. After that they said to go for it but contact them before covering up any insulation.
They are very hot on insulation now. I kept records of all the U value calculations and have kept receipts so I can prove materials used. I've taken lots of photos and videos at various stages. I have also kept of all the official document parts and how they apply to my build. I am not a professional so I have done it "by the book" quite literally.
Very clear explanation and really helpful experience and thanks for your sharing.
Your videos are so informative! I have only come across your channel today. I have been looking for information re Building Control for some time, but nothing I found so far was be so clear and concise! Exactly what I was looking for. Thank you so much for these videos!!!
Very informative and useful for an extension we are hopefully starting in a few weeks, thank you!
An excellent video, very informative.
Appreciate the time you've taken in creating this video and also thank you for passing on your knowledge to us.
Many thanks
You have explained everything really well thanks
Very clear explanation and really helpful experience and thanks for your sharing!👍🙏
Great video. Thank you
Great stuff. Thanks.
Brilliant video 👏
Nice comprehensive guide. I've just put in a building notice for a 2.3 x 4m rear extension.
Hi Darren. Thanks for watching and the great feedback. Great to hear that you have submitted your notice - good luck with the project! 👍🏻
very detailed even why dpc is used, all stages of inspection were discussed . saving hours of reading and understanding of process. many thanks for this. I would like to know what is included in permitted planning and what not ? please keep on sharing knowledge . this is gift for us
Thank you 🙏
AMAZING
I aim to Project Manage my own extension build. Thanks for the very valuable information!
How are you getting on with your extension and did you have any issues?
Thank you so much. This is a very useful video for extension project. I am currently experiencing a rear extension. I was asked to extend drainage pipe and the depth is 0.9m. But after doing so, I heard that the council said it was not deep enough. I was devastated. Money spent for nothing. I would like to check - is 0.9m good enough? Because I check online and it should be okay. Thank you for your tips :) cheers
That's the theory. In practice here in Birmingham, BC undertake five visits for a single storey extention - foundation, dpc, drains install, roof, final sign off.
Just looking at converting an existing 2.4x2x4m porch into a downstairs toilet and what started as a "quick DIY" job now seems like a mountain I have to climb!
Thanks for watching 👍 If you can afford it bring in some help as getting the job done quickly if half the battle.
very clear and helpful video! thank u so much for sharing ur knowledge. im living in merton but dont know who to talk to regarding some building/extension work for my house. may i check if u know any good building company/ construction contractors in the area?
Thank you for your response. My reply is that extension is 4m X 5.725m. Drain and sewage pipe is with 3 metre of the property confirmed by Thames Water. I have to submit application to Royal Borough of Greenwich my building notice. What is the rule to decide the type of notice to Borough for simple notice or full plan notice? Thanks
I would agree with using the Council's building control team because they are cheaper and give honest advice.
Thanks for watching and the feedback 👍
Bollocks....never use the Council, you pay them and they work for themselves, a private surveyor will work for you
Hi, can u plz tell if we need a fire rated roof lantern for a 6 meter extension on a 3 bed semi detached house ? Thanks
Hi
Do building control have the right to say that we have to put pir insulation on our inner wall of cavity wall?
We have our extension done and have issue with the building control,unfortunately they are private as I thought it would go faster and smoother but it seems to be opposite way,
Our extension is a cavity wall,break work outside and concrete block inside and it’s 100mm cavity wall insulation between but now he say we have to put 50mm insulation on our concrete block wall
Could you guide me on this pls
You suggested trees within 5m of the proposed extension need to be considered. Might I suggest you consult NBHC chapter 4.2 as trees within 20m especially those that have a high water demand and are in a cohesive soil would still impact the foundations.
Although you can’t cover everything in one video, I think you summed it up well.

Hi everyone this might sound like a stupid question but my neighbour has an extension and I'm going to build an extension running along side his is it okay that I'm running a course of block running tight to his? So i will have block running along his, a 150ml cavity for insulation and then another course of block
Blimey!
can these certificates be filed with land registry so they dont get lost?
So they checked that Grenville block of flats and materials used
I’m doing a side & rear extension plus a loft conversation where I have to raise the ridge height, so it’s a total roof off job. I’m confused as to either go full plans or building control?
Hi Barry. Thanks for watching. It sounds like you are doing amendments to a residential property so you should be ok with a building notice. 👍🏻
My question is to guide me about full plan application or building notice. If the drain or sewer is within 3 metre of the proposed extension then full plan or simple building notice will be required by Royal Borough of Greenwich which is relevant Borough. Thanks
Hi Riaz. Thanks for watching. The drains do not relate to the need for planing permission. The public drains in London are now all owned by Thames Water so you will need to contact them and apply for approval to build close to the drains. I can't say whether you need planning permission but you will definitley also need to apply for Building Control approval. 👍
Hi there can I ask you a question please on a some what related matter? I need to drill into my concrete floor (residential ground floor) to attach a fixing. I understand there is screed then the concrete then the DPM. How much depth do you think I have before I end up going through the DPM? I was thinking I drilling around 50mm into the ground. Hope you can help :) thanks in advance
Hi Christopher. Obviously I can’t say for sure but when laying a concrete floor the depth should be a minimum of 100mm but could be as much as 200mm so 50mm should be ok.
Hi Christopher. The usual depth for a concrete floor is a minimum of 100mm so 50mm should be fine. Obviously take it steady when drilling down as you will be able to see the membrane if you reach it. You could always repair it anyway in a worse case scenario so not the end of the world if you did piece it.
@@JoeBlogs thanks, I thought it may be 100mm. Its just that those plastic carcass feet types used in kitchens maybe a little weak considering the books will weigh around 400kg plus the wood. ps if you have a link or product name to repair just in case let me know, I guess it must be a silicone or similar you pour in? (should it be a drill hole. Hey many thanks for the reply and being so late as well :)
Hi, I’m looking to buy a house that had some extension work done back in 2014 to have living room and kitchen in place. The planning was approved but the sign off was not completed by the building control. The previous owner then sold it to the current owner (in 2016) who is selling the house as it along with indemnity insurance and not willing to get the completion from the building regulations as he is outside the uk. Is it advisable to buy this house? Not sure what stages were actually completed and what’s left.
Hi. Thanks for watching and the question. There is always a risk when buying a house that has had building work done even if Building Control has signed off on it. My advice would be to get a structural engineer to check out the extension and if they say that it is ok then you will have the comfort of knowing what it is sound. The work was done 7 years ago so my guess is that it should be ok as any issues should have shown themselves my now. If you do buy make sure you can assign the Indemnity Insurance policy to any future buyer who will be in the same position you are. One final tip - once you are happy ask for a reduction on the price prior to completion as this issue should be reflected in the final deal 👍
@@JoeBlogs hi, thanks for your reply. I have booked the building survey as the bungalow was built in 1950s and extension was built in 2014. Is structural engineer inspection different to the full building survey? I’ll try for reducing the price to the agent. Plus, I have also asked the council about the stages report yesterday to know what was done and left for the sign off process. Your video is very good, I don’t know much about the process and you have explained very well. Thanks
What about CDM?
Do you have to pay building control for each visit?
I was wondering the same so googled it, most councils say you have to pay the full amount (i.e. £200-500) after the first site visit, and this covers all subsequent visits.
Submit plan who will be doing it?
You never mentioned the other option! taking out indemnity insurance if you ever want to sell and not bothering with all of that at all. it is actually cheaper than the building control fees!?!?
Please explain I didn't understand your comment
Can you use building control with permitted development? I.e. without applying for planning permission? Cheers.
Yes. You always need building control to be involved but thankfully you don't always need the planners
