Boxt

BOXT is a UK platform specialised in fixed-price home heating, cooling, and energy installations: A-rated boilers, air conditioning, solar panels with batteries, heat pumps, and EV chargers. The process is 100% online: you answer a few questions about your home, compare brands and models, and get a fixed quote in minutes, with finance options and, in many cases, fast installation (including next working-day installation if you buy before the stated cut-off time).

BOXT’s value proposition combines convenience and transparency (fixed pricing and a “like-for-like” price match/beat promise) with add-on services such as BOXT Life-style plans (maintenance and repairs) plus one-off boiler repair or service visits. It’s a great option if you want to avoid open-ended quotes, have an installation handled by accredited engineers, and take advantage of recurring promo-code campaigns (for example, free thermostat gifts or air-con discounts) as well as solar-and-battery promotions.
