Answer first
Energy Saving Trust says a heat-pump service typically costs around £150, while noting that price varies by heat-pump type. Scotland-wide travel, system complexity, manufacturer requirements and whether remedial work is needed can move the final charge.
Before booking, ask what tests are included, whether a written record is supplied, whether filters and system pressure are covered, and whether the price includes travel and VAT. Repairs and parts should be approved separately.

Define the visit before comparing price
A useful service reviews the outdoor unit, accessible refrigeration and hydraulic components, pressure, filters or strainers, condensate route, controls, fault history and operating temperatures in line with the manufacturer’s requirements.
It should not automatically include refrigerant work, replacement parts, system flushing or correction of an installation defect. Those items need diagnosis, authorisation and appropriately qualified personnel.
Understand what changes the charge
Travel distance, island or rural access, number of heat pumps, cylinders, zones, filters and plant-room complexity all affect time. A first visit without commissioning records may take longer than a routine visit to a documented system.
A suspicious noise, repeated fault code or loss of pressure should be disclosed when booking so the right engineer, tools and likely parts can be planned. Calling it a routine service can delay a needed repair.
Protect the warranty and the performance
Follow the manufacturer’s required interval and evidence standard. A calendar reminder, invoice and completed service sheet are more useful than relying on memory when a warranty question arises.
Servicing is also a chance to identify changed heating curves, blocked airflow, dirty strainers or heavy immersion use before they become a winter complaint or a larger bill.
Ask for an outcome, not just attendance
The engineer should explain material findings, urgent actions and optional improvements. Settings should not be changed without recording the before-and-after values and the reason.
If performance cannot be assessed during mild weather, the report can say so and identify what evidence to collect during colder operation. Honest limits make the visit more useful.

Is £150 a fixed price?+
No. It is a current typical guide from Energy Saving Trust; actual prices vary with type, location, scope and remedial work.
Are repairs included in a service?+
Normally diagnosis may identify them, but parts and substantial remedial work should be quoted and approved separately.
Do I need the original installer?+
Not always, but use a competent provider familiar with the equipment and warranty requirements, and share the commissioning documents.
