4.0 / 5
☆☆☆☆☆
★★★★★
Pros
- MCS-certified installer — eligible for the £7,500 BUS grant out of the box
- Vaillant aroTHERM plus partnership — R290 refrigerant unit available in 5/7/10/12/15 kW (covers most UK homes including larger detached)
- Fixed-price quote model — no day-rate creep once the survey is signed off
- 7-year manufacturer warranty on the Vaillant aroTHERM plus heat pump
- Trustpilot rating consistently 4.7+ across BOXT's overall installer business (heavily weighted by boiler reviews; heat pump volumes are newer)
Cons
- No published pricing — every quote requires a survey, so BOXT cannot be price-compared against Octopus's fixed £4,460 Cosy 6 net price
- Vaillant-only on heat pumps — no choice of manufacturer if you'd prefer a Daikin, Mitsubishi, or Samsung unit
- Native promotion banned by Awin terms — partner content can read as awkwardly hedged compared to editorial coverage of installers without affiliate ties
- Heat pump install volume is materially smaller than BOXT's boiler business — most positive Trustpilot reviews are gas-boiler-led, not heat-pump-led
