Heat pump servicing in Barnet: what to expect
Aftercare matters as much as installation. For a heat pump in Barnet 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 Barnet include unvented cylinder safety checks alongside the heat pump itself. Homes in Barnet 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.
- Heat pumps installed by another company that need a new servicing arrangement
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps a year or more past installation
What's included
- Glycol or antifreeze protection test where fitted
- A dated service record for your warranty and property files
- Expansion vessel, pressure relief and water quality checks
- Unvented cylinder safety checks and legionella cycle check
- Magnetic filter and strainer clean, with system pressure topped up
If a heat pump in Barnet 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
Homes in Barnet can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump servicing in Barnet: questions
How often should a heat pump in Barnet 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.
What should I check before booking a visit in Barnet?
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.
How much does a visit cost in Barnet?
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.
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.
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.
