Heat pump servicing in Balham: what to expect
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
Service visits in Balham include unvented cylinder safety checks alongside the heat pump itself. We service heat pumps in Balham whoever installed them, including monobloc and split systems.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps installed by another company that need a new servicing arrangement
- Homes where running costs have crept up or rooms feel cooler than before
What's included
- Cleaning of the outdoor unit coil, fan area and condensate drain
- A dated service record for your warranty and property files
- Controls and error log check, with settings adjusted where needed
- Expansion vessel, pressure relief and water quality checks
- Glycol or antifreeze protection test where fitted
Heat pumps in Balham that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
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 Balham quote.

Designing for Balham's winters
Balham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat pump servicing in Balham: questions
How often should a heat pump in Balham 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.
Do you also cover Tooting?
Yes. We arrange heat pump servicing and repairs in Tooting, which is about a mile south-west of Balham, and across Greater London.
What should I check before booking a visit in Balham?
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 heat pump service cost?
An annual heat pump service has a guide price of £120–£250, including VAT. Where your price sits depends on the type of system, whether it is a split system needing refrigerant checks and whether an unvented cylinder is included. Any parts or repairs found during the service are explained and priced before any work goes ahead.
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.
