We service systems installed through us and systems fitted by other companies, including monobloc and split units. If your heat pump was installed by someone else, tell us the make, model and age when you book so the engineer brings the right parts and information. Refrigerant work on split systems must be done by an F-gas certified engineer.
Service visits in Essex include unvented cylinder safety checks alongside the heat pump itself. Landlords in Essex can arrange servicing for several properties, with a dated record for each. We service heat pumps in Essex whoever installed them, including monobloc and split systems.
Who it suits
- Heat pumps installed by another company that need a new servicing arrangement
- Landlords who need dated service records for each property
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps a year or more past installation

Heat pump servicing questions
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.
What does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
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.
