Heat Pumps and Heating Upgrades in UK Homes: What Buyers and Landlords Should Check

The Short Answer

Most UK homes are heated by a gas boiler and radiators. Heat pumps are an alternative that move heat from the air or ground into the home using electricity. They suit well-insulated homes best, and a poorly insulated home may need other work first. Whatever the system, ask for its age, its servicing record and the Energy Performance Certificate (EPC) before you commit.

What to Look for in the Heating You See

• Type of system: gas boiler, electric heaters, oil, district heating or a heat pump.
• Age of the boiler or heat pump, and whether the manufacturer's guarantee still runs.
• Service history. Ask for records of annual servicing.
• Controls: a programmable thermostat and radiator valves help control costs.
• Radiators and pipework: look for leaks, rust marks or cold spots.

The EPC Is Your Starting Point

The EPC rates a home's energy efficiency and lists recommended improvements. It is also a legal requirement to provide one when marketing a property for sale or rent. Look at the heating and insulation sections, and remember that it is an estimate, not a bill. Landlords should also check the current minimum EPC rules for lettings on GOV.UK, because they have been under review.

What Is a Heat Pump?

An air-source heat pump takes heat from outside air and delivers it to the home, usually through radiators or underfloor heating. A ground-source system uses pipes in the ground. Heat pumps usually run at lower water temperatures than gas boilers, so they work best with good insulation and suitably sized radiators.

• Pros: efficient use of electricity, no gas on site, and in some cases government support, which you must check on GOV.UK as schemes change.
• Cons: upfront cost, outdoor space for the unit, planning or noise considerations, and the need for a suitable heat distribution system.

Questions to Ask When Buying

• Who installed the system, and is there a certificate or guarantee that passes to the new owner?
• If there is a heat pump, is the installer registered with a recognised scheme, and what is the servicing arrangement?
• What do recent bills look like? Ask the seller for a typical year of gas and electricity use.
• Is the home insulated, with double glazing and loft insulation, and what does the EPC recommend?
• If it is a flat, is heating individual or communal, and how are communal charges calculated?

If You Plan to Let the Property

Landlords have gas safety and electrical safety duties. A working, serviced heating system is part of what tenants expect, and a broken boiler in winter is a priority repair. Our guide on landlord gas safety, EICR and smoke alarms covers the checks before letting.

If you manage from overseas, set up a clear process with your letting agent for emergency repairs and servicing dates, and keep the records.

Before You Upgrade

• Ask a qualified heating engineer for a heat-loss survey and written quote.
• Compare quotes from more than one installer.
• Check whether the property is leasehold, as you may need the freeholder's consent for outdoor units.
• Check conservation-area or planning rules for external equipment.
• Check any grant or scheme on GOV.UK for current eligibility.
