Rather than a new thread I thought I may as well tac onto this one.... I have just had a budget cost for a new electrical connection. It's two new build houses, and then potentially changing the house already connected from single phase to three phase. I originally had it quoted prior to April 2023 (budgeted then was £23k), I held out at the time thinking the changes to how network upgrades were costed would benefit me but have just had a quote for £30k. I've attached the budget quote and breakdown, and also how much of the upgrade I appear to be contributing to (90%!). I must admit I don't fully understand how the whole costings work and if I have any case to argue this is for "re-inforcement assets" as mentioned in the thread.

Yes will be screeded over.

Yes, had thought about doing that as an option - wasn't sure how well 450mm x 1200 sheets would "sit" down to lay and then put UFH

Was my original plan - why is PIR not seen as good on the forum?

Hi all, With my project slowly progressing, I've come across the chance of a deal on some PIR insulation. I'm trying to see if I can make it work for me and save me a good few thousand in the process, the issue is the the cavity insulation available is 75mm so not enough for what I am trying to achieve. Has anyone/is it possible to double up the insuation or would it become a complete faff to install? thanks

Not sure there will be tax to pay (except for some import admin fees), though there will be VAT to pay as it enters the country, which you should then be able to reclaim. Not quite how it will work for an individual though (I import as a company) - I'm assuming you will just get an invoice for the VAT elelement which you can then reclaim.

Yes, way too big for what I need at circa 600+m2 and by the time I actually get around to building it the kids will probably have moved out. 350 gabion baskets arrived yesterday on a container from China so at least I can now make a start on some retaining walls.

Yes appears geobrick is now referred to as Geostylistix.

Out of interest, what bricks have you been looking at? I m currently looking at Geobrick

For information, just had an Internorm quote back - as I quickly calculate it, roughly 130m2 (including front door, some additional exterior doors, and two large gable ends), came in at roughly £850m2 fitted.

What U value does this come out at? Ditto for yours @joe90

Yes a small section needs to be 5m (depending on some other landscaping factors - long story), the vast majority is one story in height

So have spoken to a couple of people today, and gabions are looking a possibility with initial suggestions it will be a 2m base tapered down as it rises. The base only needs to be type 1 mot, rather 200mm of concrete/rebar as in the original design (and 3.5 meters deep for the heel). Once the design comes through I can cost it more fully.

Yes, gabion is currently what I am looking to explore just to see if it is viable and more cost effective. I have looked into sheet piled steel but that was way way over the concrete/rebar route (even if much simpler to install) For both properties it's circa 100 linear meters of wall required so not insignificant. On the plus side, once this is sorted the build becomes more straightforward. Space required for gabion isn't an issue on this site.
