What you need to know
Price only makes sense once the scope is clear
Energy Saving Trust currently gives around £150 as a typical annual servicing allowance, but the actual price varies with location, system, access and what is included. Ask for a written scope rather than comparing one headline figure.
Follow the manufacturer, warranty and installer requirements for your exact system. Many owners arrange a yearly visit, but the required interval and evidence should come from those documents—not a universal promise online.
Request a system-specific heat-pump service
Send the make, model, age, postcode and any current symptoms so FLO can confirm availability and whether servicing or diagnosis is appropriate.
What a service can examine
The exact schedule should follow the manufacturer and installer documentation. A competent visit may combine visual condition, accessible hydraulic components, outdoor airflow, controls, operating observations and recorded findings.
A checklist is useful, but it should not become a promise that sealed or specialist components will be opened regardless of qualification or need.
- Outdoor unit condition and clear airflow
- Visible pipework, insulation and signs of leakage
- System pressure and accessible filters or strainers
- Controls, schedules and reported comfort
- Fault history and operating observations
- Written actions and any further diagnosis required
Know whether you need a service or a repair
Choose routine servicing when the system is operating and you want scheduled maintenance, warranty evidence and a condition record. Choose fault help when heating or hot water has stopped, an error keeps returning, pressure will not hold, electricity use has changed sharply or the unit has unusual noise, ice or leakage.
Disclose the symptom before booking. That gives FLO a chance to identify the equipment, request useful photographs and explain whether a maintenance appointment, diagnostic visit or manufacturer route is most appropriate.
- Routine service: planned checks and written findings
- Fault diagnosis: investigate a reported problem
- Repair: authorised work after the cause and options are understood
- Performance review: controls, temperatures and measured behaviour
Prepare the system information before booking
Photographs of the data plates, indoor equipment and controller help identify what the engineer will attend. Include the installation date, last service, current pressure, recurring alerts and whether the original installer remains involved.
If heating or hot water has been lost, say so clearly. You may need fault diagnosis rather than a routine maintenance appointment.
Safe homeowner checks between visits
Keep the outdoor unit free from leaves and obvious obstructions while respecting the manufacturer’s safety guidance. Watch for damaged insulation, unusual persistent ice, unexpected pressure change or recurring fault messages.
Do not remove covers, alter sealed components or repeatedly reset a returning fault. Record what happened and when so the engineer receives useful evidence.
- Keep manufacturer clearances unobstructed
- Check user-visible pressure only as instructed
- Note fault codes before any permitted reset
- Use the documented heating and hot-water schedule
- Keep handover and service records together
Compare service quotations properly
Ask what equipment and checks are covered, whether travel is included, how additional parts or diagnostic work are authorised and what written record you will receive.
Where a warranty requires particular evidence or provider qualifications, confirm that before the visit. A cheap generic checklist may not meet the installed system’s actual requirement.
Keep in mind: Servicing can identify maintenance and operating issues, but it cannot correct an underlying design limitation without separate investigation and agreed work.

Questions people ask
How often should an air source heat pump be serviced?+
Follow the manufacturer, warranty and installer requirements for the exact system. Provide the model when requesting a service.
Can FLO service a heat pump installed by another company?+
Provide the make, model, age, postcode and service history so FLO can confirm whether the team can help and what kind of visit is appropriate.
Will servicing reduce my electricity bill?+
It may identify settings, airflow or maintenance issues, but bills also depend on heat demand, tariffs and the original design. Savings should not be guaranteed.
Is a fault repair included in a routine service?+
Not necessarily. Ask how diagnosis, parts and additional work are handled if the service finds a fault.
