Heat pump servicing for Marlborough homes
Aftercare matters as much as installation. For a heat pump in Marlborough 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 Marlborough whoever installed them, including monobloc and split systems. Homes in Marlborough and across Wiltshire 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
- Heat pumps a year or more past installation
- Landlords who need dated service records for each property
What's included
- Glycol or antifreeze protection test where fitted
- Expansion vessel, pressure relief and water quality checks
- Controls and error log check, with settings adjusted where needed
- Unvented cylinder safety checks and legionella cycle check
- Refrigerant circuit checks on split systems by an F-gas certified engineer
If a heat pump in Marlborough has not been serviced for a while, the first visit includes a full check of settings and pressures.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Marlborough quote.

How long is the heating season in Marlborough?
On the shortest day Marlborough gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump servicing in Marlborough: 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 Swindon?
Yes. We arrange heat pump servicing and repairs in Swindon, which is about 10 miles north of Marlborough, and across Wiltshire.
Can you work on a heat pump in Marlborough that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Marlborough, whoever fitted them. Tell us the make and model when you get in touch.
Can you service a split system?
Yes. Split systems have refrigerant pipes running between the outdoor unit and an indoor unit, and checks on that refrigerant circuit must be done by an F-gas certified engineer. We arrange the service so a suitably certified engineer attends. The water side, controls and cylinder are checked in the same visit, just as on a monobloc system.
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.
