Heat pump aftercare services
Independent support for existing heat pump systems across Hampshire, Surrey and Sussex.
Guide prices shown clearly, with no hidden call out fees.
Useful if:
Your heat pump is due its annual service
You have moved into a property with an existing heat pump
You want the system checked before winter
You are unsure whether it has been maintained properly
You want a general performance review
From £210 - includes full strip-down service, expansion vessel checks, filter/strainer inspected and cleaned, general system checks, service certificate upon completion. Typical service time 1.5 - 2 hr.
Annual heat pump servicing
A thorough annual service helps you heat pump run safely, reliably and effectively -
and gives you a clear picture of whether the system was set up correctly in the first place.
Many heat pump owners discover during a first service that flow temperatures are set too high, weather compensation is incorrectly set, or simple changes could significantly reduce their running costs.
Heat Pump Optimisation
A heat pump can be working — technically — while still performing badly. High flow temperatures, incorrect scheduling, poor balancing or unnecessary complexity can all increase running costs and reduce comfort without triggering any fault codes.
Optimisation focuses on making the system run as it should: steadily, efficiently and reliably, with running costs that reflect the technology.
Useful if:
Electricity bill seems too high
The house feels unevenly heated
The system runs constantly but comfort is poor
Weather compensation is disabled or badly configured
Flow temperatures are set too high
You are unsure whether the system was set up and commissioned properly
You want to understand how to run the system efficiently
Priced as controls & optimisation visit (from £220) or half-day review (from £350) depending on scope. I’ll advise which is appropriate after hearing about your system.
Your heat pump is showing fault codes
Heating or hot water is unreliable
Rooms are not reaching temperature
The system keep stopping or locking out
The system is noisy or cycling frequently
Previous visits have not resolved the problem
You want an independent second opinion
From £180 - includes 90 minutes on site. £80 / hr thereafter.
Fault finding and diagnostics
Heat pump faults are not always caused by the heat pump itself. The problem can come from controls, sensors, flow restrictions, pumps, valves, pipework, system design or original commissioning.
Rather than guessing or swapping parts unnecessarily, I take a methodical approach to finding the actual cause, and explaining it clearly.
Useful if:
Heating Systems & Controls
Controls are one of the most common reasons heat pump systems underpeform. A properly set-up system should run steadily at the lowest practical flow temperature, using weather compensation and sensible scheduling - not constant manual adjustment.
If you’re regularly changing settings, or the house overheats and underheats in cycles, the controls almost certainly need attention.
Useful if:
You do not understand your controls
The house overheats or underheats
You keep changing settings without improvement
Weather compensation is not set up properly
You want to reduce unnecessary cycling
From £220 - includes 2 hours on site. £80 / hr thereafter.
Guide Pricing
Every system is different, so the prices below are intended as a guide. All visits are based on time on site — any parts, refrigerant, inhibitor or additional materials required are priced separately and always agreed with you before any work is carried out.
Annual heat pump service — from £210
A thorough annual service to keep your heat pump running safely and reliably. Includes a full strip-down of the external unit, filter and strainer checks, pressure checks, electrical checks, flow rate check and a general review of system condition.
If I spot signs of poor setup, high flow temperatures or controls issues during the visit, I'll flag them clearly. Resolving those issues falls under a separate optimisation or controls visit — the service is focused on the condition and safety of the heat pump itself.
Diagnostic / fault finding visit — from £180
Includes 90 minutes on site. £80/hr thereafter.
For faults, lockouts, poor heating, hot water issues or unexplained performance problems. I take a methodical approach to finding the actual cause rather than guessing or replacing parts unnecessarily.
Controls & optimisation visit — from £220
Includes 2 hours on site. £80/hr thereafter.
A focused review of your settings, schedules, weather compensation and overall system performance. If your bills seem too high, the house isn't heating evenly, or you've never had the controls properly explained, this is the right starting point.
Half-day system review — from £350
For systems with ongoing comfort, efficiency or setup issues that need a more detailed assessment. Covers a thorough review of the heat pump, controls, emitters, flow temperatures and pipework.
Full-day remedial / optimisation work — quoted individually
For more involved system improvements including balancing, controls work, pipework changes or remedial work following a diagnostic or system review.
System upgrades & installation work — quoted individually
Following a review of the property, system and scope of work.
Additional parts & materials
Any parts, components, inhibitor or other materials required during or following a visit are not included in the above prices. These will always be identified, quoted and agreed with you before any additional work or ordering takes place. There are no surprises.
Not sure which service you need? Describe what's happening and I'll recommend the most suitable option.
System upgrades and remedial work
Some heat pump problems are caused by the wider heating system rather than the heat pump unit. Pipework, emitters, pumps, buffers, valves, controls and hydraulic layout can all affect performance.
I can advise on practical upgrades or remedial work where the existing system is holding the heat pump back.
Useful if:
The original installation was poorly designed
Radiators are too small for low temperature heating
Flow rates are poor
The system has unnecessary complexity
The property has mixed heating circuits, multiple zones
You need changes to improve comfort or efficiency
Larger work is quoted individually after reviewing your property and system.
