30°C or 40°C?
We found no official kWh figure for a 30°C wash against 40°C. UK ecodesign rules require manuals to include “a statement that the most efficient programmes in terms of energy consumption are generally those that perform at lower temperatures and longer duration”.6
Bosch: “The actual washing temperature is specified in the user manual and, depending on the load size, may deviate from the selected washing temperature for reasons of saving energy.”7
Who these figures cover
Costs use the Ofgem price cap average for England, Scotland and Wales, 26.32p per kWh by Direct Debit, 1 October to 31 December 2026. Your region and tariff change it.4
HMRC: “The temporary zero rate applies from 1 October 2026 to 30 June 2027.” The Budget on 28 October 2026 extended it from 31 March (announced; the legislation is due in early 2027). Gas stays at 5% VAT.5 In Northern Ireland, use the unit rate on your bill.
