Thank you

Good, or not. If it had been, would just say demolition and rebuild. Have you considered re-roofing? May work out easier and cheaper, and you can add in PV if suitable.

No. But the Met Office will have some data from your nearest weather station. https://www.metoffice.gov.uk/research/climate/maps-and-data/historic-station-data It is really the distribution you are after, not the mean value.

Is your place a Cornish Unit?

Was at school with someone called Flint. Got expelled for cheating in his 'O' Levels.

@AliG There is lots of info on how i is calculated on the Ofgem site. https://www.ofgem.gov.uk/information-consumers/energy-advice-households/check-if-energy-price-cap-affects-you

Or buy some of these

You still got that spreadsheet and are you willing to share it?

That seems quite high to me. My daytime usage is sub 15 kWh a week. That would only go up slightly if there were more people in house.

If you never want to see Wendy again, @pocster will show them off in person.

Don't think I am. I am on a variable standard rate. May just check again. Every time I have looked into swapping, the most I have been able to save us £9/year. I am not going to bother for that. I am a low user on E7, 80% of my usage is at 14p.

I did.

Not sure what "all the numbers" are. Assuming power then multiply by the correction factor.

What I pay for EDFs day rate.

That will be the Lizard then. Can you change the roof to a warm roof?

Yes. Don't need much as it disperses quite a but when mixing. Pretty sure it is already used on thin floors. https://concretecountertopinstitute.com/free-training/introduction-to-gfrc-glass-fiber-reinforced-concrete/

Can you isolate it, loosen the joints, swivel down and remove?

Yes, no need to teach the craft people how to measure and add up. I had to teach IT on the plumbing course. Monday afternoon, in the room next to the sports field. Monday afternoon was when the girl's football team practiced.

I went to Jeremy's not long before he moved in. I was amazed how quiet and non echoy it was.

How much does your car take in a usual week?

Thought of that, but my day usage is less than 2 kWh, 50p a day.

Photographs may help.

That is when used with a polyester resin, concrete is different.

Will improve the tensile strength, which will help with reducing the possibility of cracking due to bending. Bending and buckling is really just the compressive and tensile strength counteracting each other.

You could put in a pinch of glass fibre choppings in the concrete mix, though not sure how much it will affect the surface finish.
