The answer
Will your existing electricity supply support a heat pump?
Often, yes, but an electrician needs to check your supply alongside other heavy users such as showers, cookers and EV chargers. The electricity network may also need to be notified or approve the work.
01 / 03
Count all the electricity the system may use
The heat pump, any backup heater, hot-water immersion and circulation pumps all need power. An electrician should compare that with what the rest of your property may use at the same time.
02 / 03
Think about future chargers or other upgrades
An EV charger, electric shower or second heat pump could change the answer. Tell the electrician about work you may add later so the supply is not checked in isolation.
03 / 03
Ask who contacts the network operator
Your local electricity network may need a notification or an application. Agree who will handle it and when, before equipment is ordered.
Who checks the electrical supply before work starts?
The installer needs the heat pump's electrical characteristics and the property's existing supply details. An electrician can assess the consumer unit, cable route and likely load. The distribution network operator handles the network-side notification or application under the applicable process; the procedure and timing depend on the equipment and connection.
Ask who will submit the information, when a response is needed and whether a supply upgrade or limitation is possible. If solar, storage or EV charging is planned, include those systems in the same electrical picture rather than treating each one as an unrelated addition.

Could a heat pump work at your property?
Every property is different. A free survey checks heat loss, hot water and radiators to see whether a heat pump may fit before a system is priced.
