Heat pump servicing in Wandsworth: what to expect
Aftercare matters as much as installation. For a heat pump in Wandsworth 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.
Service visits in Wandsworth include unvented cylinder safety checks alongside the heat pump itself. If a heat pump in Wandsworth has not been serviced for a while, the first visit includes a full check of settings and pressures.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Heat pumps installed by another company that need a new servicing arrangement
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
What's included

- A dated service record for your warranty and property files
- Cleaning of the outdoor unit coil, fan area and condensate drain

Heat pump servicing in Wandsworth: questions
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.
Do you also cover Putney?
Yes. We arrange heat pump servicing and repairs in Putney, which is about a mile west of Wandsworth, and across Greater London.
Can you work on a heat pump in Wandsworth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Wandsworth, whoever fitted them. Tell us the make and model when you get in touch.
Is servicing needed to keep my warranty valid?
Often, yes. Many manufacturer warranties require an annual service with a dated record, and some extended warranties require an approved installer. Manufacturer warranties pass to you, and the length depends on the make and model. Check your warranty documents, and keep every service record safe with your MCS certificate and handover pack.
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.
