Heat Pump Service Plus
]
Most heat pump servicing is a single yearly visit. Someone checks the heat pump, ticks the boxes and leaves.
Heat Pump Service Plus is different. We look at your whole heating system — not just the heat pump.
We help optimise it for efficiency, prepare it properly for winter and give you access to experienced heat pump support throughout the year — not just on the day an engineer visits.

Is Service Plus Right for You?
Service Plus is for homeowners who already have a heat pump installed and want it properly looked after.
If you're still planning an installation, our Pre-Installation Design or Heat Loss Survey is the better place to start.
If your heat pump already has a specific fault or isn't working properly, take a look at Fix My Heat Pump.
Already installed and working? Service Plus is about keeping it working well, efficiently and reliably.
How This Heat Pump Service Works
Start with a short enquiry telling us about your heat pump, your heating system and anything you're unhappy with.
One of our heat pump experts will then arrange a short video call to understand your system, any problems you're experiencing and what you'd like to improve whether that's lower bills, warmer rooms or simply knowing your system is set up properly.
If you're happy to proceed, we'll arrange your Service Plus assessment.
If you don't already have a suitable room-by-room heat loss calculation, we'll complete one as part of your first-year assessment at no extra cost.
That gives us the information we need to assess your radiators, flow temperature and system performance properly rather than guessing.
What's Actually Included in Your Annual Heat Pump Service
Heat pump service and operational checks
Heating system pressure
Expansion vessel checks
Zone valve operation
TRVs and radiator performance
Heating controls and thermostat settings
Flow temperature optimisation
Weather compensation and system settings
Heating-mode performance
System balancing where required
Performance checked against your property's heat loss
If your heat pump also provides cooling, we'll check its cooling operation too.
Where we find something worth improving whether that's a setting costing you money, a blocked filter, an underperforming radiator or another system issue we'll explain exactly what we've found and what we'd recommend doing about it.
Where appropriate, we can provide a price for the work, but you're never under any obligation to use us. You're welcome to use your own plumber or electrician, and we'll provide them with the technical information they need.
Getting Your Heat Pump Running as Efficiently as Possible
Heat pumps generally become more efficient as flow temperatures come down.
Using your property's heat loss alongside the heating system you actually have installed, we'll work out the lowest practical flow temperature your home can run at while still keeping you comfortably warm.
We'll also show you how to use your heat pump efficiently day to day, so you're not left trying to work it out yourself.
Direct Engineer Support Throughout the Year
As a Service Plus member, you'll have access to our technical support team Monday to Friday, 8am–6pm.
For urgent problems raised during those hours, we aim to respond within one working hour.
Wherever possible, we'll help diagnose problems remotely. If somebody needs to attend your property, we'll help establish what's likely to be wrong and what needs to happen next.
You can use your own local engineer if you prefer we're happy to work alongside them and provide the technical information they need.
Ready for Winter
Your annual service will normally be arranged before the main heating season, typically around September or October.
We'll run the system in heating mode, check the wider heating system, review your settings and deal with anything we identify while there's still time to do something about it.
The aim is simple: get your heat pump ready before you actually need it not discover a problem during the first cold week of winter.
Heat Pump Service Plan Cost
This isn't just an annual heat pump service. You're paying for us to understand your whole heating system, help optimise how it runs and be there to support you throughout the year.

Frequently Asked Questions
How is this different from a standard heat pump service?
A standard heat pump service is usually a single yearly visit and nothing more. Service Plus includes that annual heat pump service, but adds a first-year heat loss assessment, ongoing system optimisation, and direct access to technical support throughout the year, not just on the day the engineer happens to be there.
Is this the same as other heat pump service plans or maintenance plans?
Do I have to use your team for any repair work you recommend?
What if I already have a heat loss calculation done?
How much does the heat pump service cost with Service Plus?
Can I cancel after the first year?
What happens if my heat pump breaks down during the year?
