Do you have an architect helping you? Ours dealt with all the CIL stuff for us.

I agree and is what we did. Just giving options. 😉

And you can use (afaik) 12.5mm at 600mm centres for ceilings but you need noggins for the board ends. although happy to be corrected if this isn’t the case but it is my understanding

I believe it’s the weight bearing capacity of the MF ceiling. A standard 1200mm grid as per BG design will take a single sheet of PB but if you want thicker or soundbloc or double boarded then you need to make the grid smaller to take the extra weight. the BG docs do state this.

We have exactly this setup and seems ok to us!

As a minimum!! If we only had to comply we’d all have leaky poorly insulated houses. 🤣

Good luck. I hope you find a solution. Our external blinds do a wonderful job of keeping the house cool without us having to rely on the AC too much.

Would one find these on Autotrader?

@mads have you approached the external blind companies to see if they have drawings for what you need?

Doesn’t help you but this was pretty trivial in our timber frame! ☺️

I think standard 12.5mm and a skim gives 30mins protection. Maybe 15mm standard plasterboard gives the same without a skim? sure someone knows for sure though.

+1 to this. Our BCO asked us to do something that would’ve costed us thousands so I read the regulations and put forward my arguments as to why it wasn’t necessary and got told I was right.

Doesn’t mean they’re no good. Just means you need to do more research! Companies house checks. Google searches. Ask them to visit on-going and previous builds etc. we used Flight Timber and visited previous builds and were very happy with our build in the end. Didn’t stop them from going under and people losing money though so no matter who you choose you have to be careful. There are a number of threads on here about the subject.

The “profit” we make from buying off-peak to exporting has reduced with the increase of prices the other day. But it’s still a profit! If prices go up any further I’ll need to make some changes. But it works for now. my battery inverter says it’s Octopus friendly so I might look in to moving to Agile over the summer to charge the batteries when it’s cheapest. But research is required

+1 to this! In fact if I were to ever do it again I would swap our attic trusses for a cut roof. The attic trusses were a pain to membrane around.
