Should You Register for VAT?
In the UK, you must register for VAT if your taxable turnover exceeds £90,000 in any rolling 12-month period. But should you register before you hit that threshold? Here's what tradesmen need to know.
Pros of voluntary VAT registration: You can reclaim VAT on business purchases — tools, materials, vehicle costs, even your phone bill. If you spend a lot on materials, this can be significant. It also makes your business look more established to commercial clients.
Cons of VAT registration: You must charge VAT on top of your prices, which makes you effectively 20% more expensive for residential customers who can't reclaim it. You also need to submit quarterly VAT returns and keep detailed records. There's more admin, though software like A.X.E.L can handle most of it.
The bottom line: If most of your work is for VAT-registered businesses (commercial clients, main contractors), registering early usually makes sense — your clients reclaim the VAT anyway, and you get to reclaim yours. If your customers are mainly homeowners, hold off until you have to.
How VAT Works for UK Tradesmen
Value Added Tax (VAT) is a tax on goods and services charged at each stage of production. As a VAT-registered tradesman, you charge VAT on your invoices and pay it to HMRC quarterly, minus any VAT you've paid on business purchases.
Most construction and trade services are charged at the standard 20% rate. Some work qualifies for the reduced 5% rate — for example, installing energy-saving materials in residential properties, or converting a non-residential building to residential use. New-build housing is zero-rated.
This calculator helps you quickly work out VAT in both directions: adding VAT to a net amount for your invoices, or extracting VAT from a gross amount to see the breakdown. It uses the current UK VAT rates and runs entirely in your browser.
