Three ways to heat this home

Compare your options

Option 01

Air to water

A conventional heat pump outdoor unit, heating radiators or underfloor via a hot water cylinder — the most familiar route, and usually the lowest cost.

Typical cost, after grant

£4,350

Best if: You want the simplest, lowest-cost route and don't need summer cooling.

Price breakdown

Heat pump unit£5,000
Hot water cylinder£1,100

Electrical works£550
Labour£3,000
MCS commissioning & certification£350
Subtotal£11,850
BUS grant–£7,500

Option 02

Air to air + hot water

Wall-mounted indoor units heat and cool each room directly from one outdoor unit; hot water is handled by a separate solution.

Typical cost

£10,850

Best if: Keeping the house cool in summer matters as much as heating it in winter.

Price breakdown

Heat pump unit (multi-split)£5,000
Hot water solution£1,600
Pipework, controls & electrical£1,500
Labour£2,400
MCS commissioning & certification£350

Option 03

Samsung EHS Quint

One outdoor unit provides heating, cooling and hot water simultaneously — including heat recovery, where heat pulled from a room being cooled goes into the hot water cylinder instead of being dumped outside.

Typical cost, after grant

£11,400

Best if: You want heating, cooling and hot water from a single unit, and value the heat-recovery efficiency.

Price breakdown

Quint outdoor unit (12.5kW)£7,250
Indoor units & hydro-kit£3,750
Hot water cylinder£1,100
Pipework & controls£2,400
