Heat pump servicing in Twickenham: what to expect
Aftercare matters as much as installation. For a heat pump in Twickenham the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
We service heat pumps in Twickenham whoever installed them, including monobloc and split systems. Homes in Twickenham and across Greater London can book servicing at a time of year that suits them, ideally before winter.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Homes where running costs have crept up or rooms feel cooler than before
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
What's included
- Magnetic filter and strainer clean, with system pressure topped up
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Glycol or antifreeze protection test where fitted
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- Controls and error log check, with settings adjusted where needed
Service visits in Twickenham include unvented cylinder safety checks alongside the heat pump itself.

Heat pump servicing in Twickenham: questions
How much does a visit cost in Twickenham?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
What should I check before booking a visit in Twickenham?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Will the engineer need access indoors as well as outside?
Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.
What does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
How often should a heat pump be serviced?
Once a year is the usual recommendation for air source heat pumps, and many manufacturers require it as a warranty condition. An annual visit cleans filters and strainers, checks pressures and controls, and tests the unvented cylinder's safety devices. If you notice a drop in performance, unusual noises or repeated error codes between services, arrange a visit sooner.
