A heat pump is a major investment — and in the UK the quote determines more than the price. Grant support such as the Boiler Upgrade Scheme (England and Wales) requires an MCS-certified installer, a proper quote is built on a room-by-room heat-loss calculation, and the outdoor unit has to meet planning noise limits. We check your heat pump quote so you know whether the promised savings are realistic and what you are committing to contractually.
What do we check?
- ✓ Price breakdown — is every item specified or only roughly estimated?
- ✓ Scope — what is and isn't included in this quote?
- ✓ Included / excluded — VAT, materials, transport, waste removal?
- ✓ Extra work — how and when is it communicated and approved?
- ✓ Warranty — on labour and materials, for how long and under what conditions?
- ✓ Schedule — is the completion date binding or only indicative?
- ✓ Payment — are instalments tied to progress or set arbitrarily?
- ✓ Terms — what are the cancellation and liability clauses?
- ✓ Missing information — what isn't stated but should have been?
- ✓ Questions for the supplier — concrete points to clarify.
Common risks
- ⚠ No room-by-room heat-loss calculation behind the quote — an MCS requirement, and without it the system size is a guess
- ⚠ MCS certification not stated — without it, grant support such as the Boiler Upgrade Scheme is off the table
- ⚠ The efficiency (SCOP) is based on ideal conditions that don't apply to your home or radiators
- ⚠ Radiator upsizing, pipework changes or a hot-water cylinder are needed but not included
- ⚠ No noise assessment for the outdoor unit against planning (permitted-development) limits
- ⚠ The warranty is conditional on an annual service, but the service cost isn't in the quote
- ⚠ VAT charged on the installation while energy-saving installations are currently zero-rated in Great Britain
- ⚠ The warranty on installation is shorter than the manufacturer's warranty on the unit
Example questions for your supplier
After our analysis we send you concrete questions to put to the supplier. For example:
- 1 "Can I see the room-by-room heat-loss calculation this quote is based on?"
- 2 "Are you MCS-certified, and do you handle the Boiler Upgrade Scheme application?"
- 3 "What efficiency (SCOP) do you expect in my specific situation, at my flow temperature?"
- 4 "Are radiator changes, pipework and a hot-water cylinder included in the price?"
- 5 "Does the outdoor unit pass the planning noise assessment at my boundary?"
- 6 "What are the exact costs and terms of the annual service the warranty requires?"
