A heat pump that runs without regular maintenance is one that quietly becomes less efficient, more prone to faults, and shorter-lived. Annual maintenance from Brook Renewables keeps your system performing the way it was designed to, protecting your investment and your comfort throughout the year.
Why Annual Maintenance Matters
Heat pumps are built to last, but they work continuously across changing seasons and varying demand. Over time, components wear, filters accumulate debris, refrigerant levels can shift, and small issues develop that are invisible until they become costly problems. An annual maintenance visit catches all of this early, before it affects performance or leads to an unexpected breakdown.
Homeowners who invest in regular maintenance consistently see lower energy bills, fewer emergency callouts, and longer system lifespans compared to those who don’t. Most heat pump manufacturers also require evidence of regular servicing to honour warranty claims, making annual maintenance a practical necessity as much as a good habit.
What Our Annual Maintenance Visit Covers
Every maintenance visit carried out by Brook Renewables is thorough and methodical. Our engineers follow a comprehensive checklist designed to assess every part of your system, not just the components most likely to cause problems.
Our annual maintenance includes:
- Full system performance check against manufacturer specifications
- Inspection and cleaning of filters, coils, and heat exchanger surfaces
- Checking all electrical connections, terminals, and control boards
- Lubrication of moving parts including fans and pump assemblies
- Flow temperature review and system optimisation
- Testing of defrost cycles and safety cut-out controls
- Inspection of the outdoor unit for debris, corrosion, or physical damage
- Review of zone controls, thermostats, and time scheduling settings
- A written maintenance report detailing findings and any recommended actions
If we identify anything during the visit that needs attention, we will explain it clearly and provide a quote before any additional work is carried out.
Keeping Your System Running at Peak Efficiency
Heat pumps are rated by their Coefficient of Performance, which measures how much heat they produce relative to the electricity they consume. A well-maintained system holds close to its rated efficiency. A neglected one can drop well below it, meaning you pay more to heat your home for no good reason. Our maintenance visits are designed specifically to keep your system as close to its rated performance as possible.
We also review your system settings during every visit. Over time, heating schedules and flow temperatures are often left on default settings that do not suit how a household actually uses heat. Small adjustments here can make a noticeable difference to both comfort and running costs.
Suitable for All Heat Pump Types
Brook Renewables carries out annual maintenance on all major heat pump types and brands, including:
- Air-to-water heat pumps

Whether your system was installed by us or by another contractor, our engineers have the training and experience to service it correctly.
