Questions

How do I take VAT off a total?

Type the total and choose 'remove VAT' — it divides by 1.2 (at 20%) to give the net and the VAT.

Which rate for energy-saving work?

Some energy-saving installations in homes are zero-rated — check the current HMRC guidance for your job.

Is this official?

It's a calculator using the standard rates. Your accountant or HMRC guidance decides which rate applies.
