Annual servicing isn't just recommended — it's essential for maintaining efficiency, protecting your warranty, and catching problems before they become expensive. Here's exactly what a proper service includes. By Craig Ball 28 March 2026 5 min read ![How Often Should You Service a Heat Pump? — featured image](/assets/blog-heat-pump-servicing-BE9IO_6O.jpg) ## The Short Answer: Annually Every heat pump manufacturer recommends annual servicing. This isn't a suggestion — it's typically a condition of your warranty. Skip a service and you risk voiding warranty coverage on a system that cost £8,000–£15,000 to install. Beyond warranty requirements, annual servicing catches small problems before they become expensive failures. A £150 [annual heat pump service](/services/heat-pump-servicing) can prevent a £2,000 compressor replacement. ## What a Proper Service Includes A genuine heat pump service — not just a visual check — should include: refrigerant pressure and temperature checks, electrical connection tightness testing, filter cleaning, condensate drain inspection, flow temperature verification, COP measurement, and a functional test of all operating modes including defrost. If your engineer isn't measuring refrigerant pressures and calculating COP, you're not getting a proper service. These measurements are the only way to verify the system is operating efficiently and catch refrigerant leaks early — they form the core of our [heat pump health checks](/services/health-checks). ## F-Gas Compliance Requirements Systems containing fluorinated greenhouse gases above certain thresholds have legal inspection requirements under the F-Gas Regulation. Most residential heat pumps fall below the mandatory leak check threshold, but proper record-keeping of refrigerant quantities is still a legal requirement. Your service engineer should provide documentation of all refrigerant handling — charges, recoveries, and leak checks. This documentation may be required if you sell your property or if the system is decommissioned. ## Signs Your System Needs Attention Between Services Don't wait for your annual service if you notice: unusual noises from the outdoor unit, ice forming on refrigerant pipes, the system running continuously without reaching temperature, error codes appearing on the controller, or a noticeable increase in electricity consumption. Early intervention on these symptoms almost always costs less than waiting. A small refrigerant leak detected early might cost £200 to repair. Left six months, the compressor damage could cost £2,500 — far more than a prompt [heat pump repair](/services/heat-pump-repair).
