How to add or remove VAT
Adding VAT: multiply the net price by the rate and add it on. At 20%, multiply by 1.2 — so £100 net becomes £120 gross (£20 VAT).
Removing VAT (working out the net from a VAT-inclusive total): divide the gross price by 1 + the rate. At 20%, divide by 1.2 — so £120 ÷ 1.2 = £100 net, with £20 VAT.

| 5% (reduced) | e.g. domestic fuel and power, some energy-saving work |
