Use low expansion foam, such as "window and door fitting foam" to avoid the over expansion

It's not the stove that is incompatible with the uvc it's the method of linkup. You need a neutral point e.g Dunsley neutraliser, thermal store, h2 panel etc. Worth looking into those pellet boilers though as the payback was something like 7 yrs with the RHI last time I looked, but you need plenty space to house the boiler and the pellets

You can look at the H2 panel if you don't want a thermal store, or there are a number of similar system link etc from Ireland. The good thing about the H2 panel is when you ring up for technical advice you actually speak to the man that invented it. If you are in a smoke control zone you only have the choice of a few boiler stoves, all expensive. There are not many Hetas fitters who can do wet boilers so that is expensive too!

You want a Macalpine ASA 10V adjustable height with built in AAV. No need for chrome behind a pedestal. Probably available at your local plumbers merchant, but worth calling first as they aren't stocked everywhere.

I've fitted an Iroko worktop from worktop express recently. It was ok, but not the best quality. Don't delay in getting that post up to support the corner. I did and within a couple of weeks I had a 10-15mm bow over a 300mm overhang

Demolishing the chimney would not count as commencement unless you are in a conservation area. You can demolish a chimney (or even a house) without permission. To fully secure your planning permission in perpetuity you would need to commence works actually related the permission. E.g lay foundations etc

Coir matting for mat wells comes on rolls 1m or 2m wide by whatever length you like £20 a square metre from your local carpet merchant

If you are painting I would do exactly as you say just patch up anything loose and it'll look 100 times better

I don't know the latest regs on it, but it's worth double checking before you start

Before you go hacking it off check that you don't HAVE to ewi (if you didn't want to)

I wouldn't bother ripping it out. Its fine. What else is left to do?

Yes, bucket of warm water any time of year!

Is this what you mean?

Have you got a photo of the existing house? I'm not sure there is much kerb appeal with the side on entrance favoured in those 30s-50s builds and I'm not convinced you are actually improving things

No noggins required if T&G, but you should be able to work it so you are ending on a joist anyway e.g 400, 800, 1200, 1600, 2000, 2400 I might make an exception if it was a major traffic point e.g first step off the stairs at the top of a landing.

No, you've definitely got a second free go. You've paid two fees you've got two free resubmissions

Before you start gluing, put your bottle of glue in a bucket of hot water if it's under say 10C (also if you use PU expanding foam).

Go for it then

I imagine that you would be better off raking it out and then regrouting if it's a long way off. If its only 1-2mm then silicone away

Unless you silicone it you will see the taper from 10 to 5mm

Re grouting won't get rid of this problem and will always catch your eye. Choose your fugi size based on the widest point and run a bead of forever white (or grey) down there and that 5-10mm will be hidden and forgotten about

My initial thoughts are you would want your soil pipes etc to be near each other and not coming down in the middle of your open plan kitchen. Clocks is a bad pinch point and you'd struggle with disabled access into the wc

The problem with selling the house to a company etc is the 3% additional SDLT tax which you would have to pay on the value. HMRC would not know that Red Kite Ltd has been contracted to build a house as there is no "VAT claim" like when you build your own house
