Hi Colnmill,
There is a DIY scheme available.
However this is only applicable where either a new house is built or where renovations are carried out on a house which has not been lived in for 10 or more years.
Please see the guidance below:
Claim a VAT refund for a conversion if you're a DIY housebuilder
If you have created a company then the company can register for VAT only if it is making taxable supplies.
If the company becomes VAT registered then it is allowed to recover VAT as input tax in the course of it's business.
Please see the guidance below:
10. Introduction to input tax
3. Working out whether you need to register.
Thank you.
