UK VAT rates explained
20% standard rate applies to most goods and services sold by VAT-registered businesses. This is the rate most tradespeople apply to their labour and standard materials.
5% reduced rate applies to energy-saving installations (boilers, insulation, solar panels under certain conditions), mobility aids for older people, children's car seats and some other specific items.
0% zero-rated applies to things like children's clothes, most food, books and newspapers. Zero-rated supplies are still "VAT-able" - just at 0% - so you can still reclaim input VAT on related purchases.
If you are not VAT-registered (turnover below £90,000 for 2026), you do not charge VAT on your sales but you also cannot reclaim VAT on your purchases. Once turnover hits the threshold, registration is mandatory.
