Heat pump servicing for Lewes homes
Aftercare matters as much as installation. For a heat pump in Lewes 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.
If a heat pump in Lewes has not been serviced for a while, the first visit includes a full check of settings and pressures. Heat pumps in Lewes that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
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 a year or more past installation
- Landlords who need dated service records for each property
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Unvented cylinder safety checks and legionella cycle check
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Expansion vessel, pressure relief and water quality checks
- Magnetic filter and strainer clean, with system pressure topped up
- Glycol or antifreeze protection test where fitted
Landlords in Lewes can arrange servicing for several properties, with a dated record for each.
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 Lewes quote.

How long is the heating season in Lewes?
On the shortest day Lewes gets about 7 hours 56 minutes of daylight, and the winter sun reaches only around 16° 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 Lewes: questions
Can you work on a heat pump in Lewes that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lewes, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Lewes be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
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.
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.
Do I need to do anything between services?
A little. Keep the area around the outdoor unit clear of leaves, snow, plants and stored items so air flows freely. Check the system pressure gauge occasionally if you have one, and note any error codes. Avoid covering the unit or building an enclosure around it without advice, as this can reduce performance.
