You could be £7,500 better off

Buy the Samsung EHS Mono HT Quiet

A heat pump is almost always installed by a certified fitter rather than bought off a shelf, but you can price the unit and parts yourself to sanity-check an installer’s quote.

Our verdict on the Samsung EHS Mono HT Quiet

For homeowners whose headline question is 'what's the cheapest decent heat pump?', the Samsung EHS Mono HT Quiet is the best-value answer. It's the most affordable of the big-five brands after the £7,500 grant — typically £3,500–£7,500 installed — while still delivering a respectable SCOP of 4.3 and a useful 65°C flow temperature.

You also get Samsung's SmartThings app for control and scheduling, so it's one of the easiest units to program around an off-peak electricity tariff. It's a smart, budget-conscious choice for a well-insulated modern home where the extreme efficiency of an R290 flagship isn't worth the premium.
