Do you have a drainage plan you can share? You would have needed something for your BC submission. You'll need to run 110mm pipe though the slab, not 40/50mm pipes.

AHH. I used optimisers that made everything safe (1v per panel) until commissioned. Good point tho.

I did 90% of our install myself, spark did the connection from inverter to the consumer unit and provided the safety check paperwork. Fitting the panels and stringing them together is pretty simple stuff.

Welcome. Learning on the job (making it up as you go along) is all part of the fun.

Looked in to this. Sedum plugs are much cheaper than the mats. Just need to be a bit more patient and do more maintenance in the first year. I think green roofs are great when done right. Go for it.

Ours is steel frame, cut through insualtion and bolted to the ICF. Support columns and walls. It's not a cheap exercise at all. Ours is 2 x 12m, L shaped. The steel along was £3k. Timber deck another grand. GRP , £1k. Paving pedestal, pavers, glass ballistrading, another £8k. Supporting walls hard to cost up but another £2k. Mostly DIY except the walls. The reason we went with a fully tanked design was to create shelter in the main patio below. You could do it with softwood timber for about £3k. I'd allow £15k for yours if you want it to the same spec and to be professionally built. Not allowing for roof etc. that could double it.

The meter you get here is determined by the tariff you choose. Fyi, we're on economy 7 and save about £300 a year compared to standard tariff. You need to shift a good 50% of usage on to the night time to make it worth it.

3. Dependent on what SE wants. 7. Do this much sooner. Before demolition..apply as soon as you get planning. 8. Will require you to have walls built etc. put ducting in early tho as part of ground works.

Just say economy 7 import / export meter. I think they are the same anyway.

Well, wood flooring or tiles are a lot more expensive than carpet (£50m² Vs £20m²), then the VAT argument is moot.

If they are tilt and turn (inward opening) then the answer is no. Can't speak for casement. I've come up with my own high tech solution....a white doorstop screwed to the window board to stop the window opening more than the depth of the reveal 🤣 In an emergency, easy to force open.

Water companies will, by default, say no. As dealing with these kind of things is a PITA. You'll have just talk and badger them. A good design will see you through. Last thing you want is to divert, a good build over design is the only approach

Depends how much you want to spend then. I've never had any issues with any IKEA pans. Tho my stellar pots are about 5x the cost but still worth it. I think they and and procook will be with me for life.

I've used the same fitting on an old lead pipe. They shouldn't leak at all. Is everything straight? How did you tighten it? I find hand tight often isn't enough for those (years of experience installing meter boxes.)

Well done, push on.
