This is a bit of a long shot, we are having an extension built, this involves knocking down an existing single storey extension and replacing it with a new 2 storey extension, anyway this can be interpreted as new build for VAT purposes?

It's 10 years since I've been involved in stuff like this so someone better qualified may come along but no.

New build means a new dwelling - not just an extension.

Nope, HMRC arnt stupid. All your paperwork for planning and building regs will define what you're building....and it will not show a new build. You could demolish 95% of your house, but that final 5% will prevent it being classed as a new build.

Some people have tried building an extension without knocking through so that the new building is VAT free and then knock through later - that doesn't work either smile

and No.

You need to demolish and rebuild. There's no point trying to be clever on this because it's astoundingly simple for HMRC to look at your planning application and see what it said. There's effectively no wriggle room.

I’m renovating a house at the moment that has been empty for 15 years, it should qualify for 5% vat, unfortunately the owner was paying council tax for that whole period so I cannot prove it’s been empty. I will be spending £100k on it so it would have been quite a saving.
