Heating, Boilers and Energy Bills: What Overseas Buyers Should Check in a UK Home

The Short Answer

Before you buy, find out what type of heating the property has, how old the boiler or heat source is, whether it has a service record, and what the Energy Performance Certificate (EPC) says. Ask for evidence rather than assurances, and have a surveyor comment on heating and insulation. If you will let the property, these points also affect tenants and your legal duties.

The Main Types of Heating

• Gas central heating. A boiler heats water that runs to radiators and taps. It is the most common system in older homes.
• Electric heating. Storage heaters, panel heaters or electric boilers. These can be simple to install, but running costs depend on the tariff and the property.
• Heat pumps. Increasingly installed, particularly in new builds. They work best in well-insulated homes.
• Communal or district heating. Common in flats, where heat is supplied from a shared system and billed through the building. Ask how it is billed and who runs it.

Checking the Boiler

• Ask for the make, model and installation date, and for the servicing record.
• Ask for the installer's certificate for any recent boiler, so you know the work was registered.
• Ask whether any warranty is transferable to the new owner.
• Ask the surveyor to note signs of poor maintenance, leaks, noise or repeated repairs.

If you will let the property in England, you will also have legal safety duties. Our guide to landlord gas safety, EICR and smoke alarms explains what to arrange.

Reading the EPC

Every home sold or let in England needs an EPC, which rates energy efficiency from A to G and lists suggested improvements. Use it to compare properties and to see what upgrades might be recommended. Read our guide to reading a listing, tenure, EPC and council tax band, and note the rules for landlords in new EPC rules for UK landlords. Because the rules have been under review, confirm the current position on GOV.UK.

Insulation, Windows and Damp

Heat is only useful if the home keeps it. Ask the surveyor about loft insulation, wall construction, window condition and any signs of damp or condensation. Our guide to flood risk, damp and subsidence lists the warning signs. A RICS survey at the right level is the usual way to get an independent view.

Flats and Leasehold Properties

In a leasehold flat, the heating system may be shared or part of the building, and the cost of replacing it can fall under the service charge. Ask the managing agent about planned works, and read the leasehold management pack before exchange.

Questions to Ask When You Cannot Visit

• Can you send a short video of the boiler, radiators and the meter?
• Who supplies gas and electricity, and can you see recent bills?
• Is there a smart meter, and what type of meter does the property have?
• Are any rooms without heating, and has anything been added without permission?
• Which upgrades does the EPC suggest, and has any been done?

Budgeting for Upgrades

If the system is old, ask a heating engineer for a written quote before you offer, so you can reflect the cost in your price. Do not rely on an agent's guess. Keep copies of invoices, as they help when you sell or let.
