Frequently asked questions

How accurate is this estimate?

It is a guide range based on national UK cost guides, adjusted for your region and finish level. Real quotes vary per trade, property and specification, so treat it as a starting point and always get at least three itemised quotes.

Do the prices include VAT?

Yes, all ranges include 20% VAT. New builds and some energy-saving works can qualify for 0% or reduced VAT; ask your installer whether your project applies.

Why is there no email wall?
