INDEPENDENT HEAT-PUMP QUOTE CHECK
Is this a good heat-pump quote?
A good quote is more than a competitive price. It should contain enough written evidence for you to understand the design assumptions, exact equipment and complete installed scope before you commit.

What should a good heat-pump quote show?
- Heat-loss evidence. Look for the whole-home figure and, ideally, a room-by-room schedule. A headline heat-pump size is not proof of correct sizing.
- Outdoor and flow design temperatures. These assumptions help explain equipment sizing, emitter requirements and expected performance.
- The exact heat-pump model. Compare the precise proposed model and ask for relevant output and performance evidence at the proposed design conditions.
- Room-by-room emitter changes. The quote should make clear which radiators or other emitters change and why.
- Hot-water design. Cylinder size, location, controls, backup arrangements and any plumbing changes should be clear.
- Electrical and installation scope. Compare electrical work, controls, pipework, condensate/drainage, commissioning, making good, removal and exclusions.
- Performance claims. Treat COP, SCOP, efficiency, bill-saving and running-cost statements as claims until their assumptions and evidence are clear.
- MCS and Boiler Upgrade Scheme statements. Keep installer claims, product information and whole-installation eligibility separate. A grant deduction on a quote is not independent verification of eligibility.
- Price before and after any grant. Record the gross installed price and grant assumption separately so quotes remain comparable.
- Warranty, servicing and payment terms. Check what is covered, what keeps the warranty valid and when payments become due.
Compare quotes side by side
When two installers disagree, put the written facts next to each other. The biggest decision risks usually become obvious quickly.
| Evidence to compare | Quote A | Quote B | Quote C |
|---|
| Whole-home heat loss | ___ kW | ___ kW | ___ kW |
| Outdoor design temperature | ___ °C | ___ °C | ___ °C |
| Design flow temperature | ___ °C | ___ °C | ___ °C |
| Exact model + nominal capacity | ___ | ___ | ___ |
| Room-by-room emitter schedule | Yes / No | Yes / No | Yes / No |
| Hot-water cylinder / controls | ___ | ___ | ___ |
| Electrical + making-good scope | ___ | ___ | ___ |
| Gross / post-grant price | £___ / £___ | £___ / £___ | £___ / £___ |
Heat-pump quote red flags
- No room-by-room heat-loss calculation is supplied or clearly promised.
- The proposed heat-pump size is presented as proof the system is correctly designed.
- Radiators are said to be suitable without showing the emitter evidence at the proposed flow temperature.
- Large efficiency, bill-saving or running-cost claims are made without their assumptions.
- Electrical work, controls, hot water, drainage, making good or commissioning are vague or excluded.
- The BUS grant is treated as guaranteed before application-level eligibility is confirmed.
- You are being pushed to pay a deposit before material design disagreements are explained in writing.
What to do when two quotes disagree
- Identify the disagreement. Is it heat loss, flow temperature, model capacity, emitters, installed scope or grant assumptions?
- Ask for the underlying evidence. Request room-by-room heat loss, design temperatures and equipment performance at the proposed conditions.
- Separate design from scope. A higher price may simply include more electrical, emitter, cylinder or making-good work.
- Ask each installer to explain the difference in writing. Do not resolve a technical disagreement by choosing the lowest number automatically.
- Compare the evidence again before paying a deposit. Home Quote Check is designed to make those conflicts and missing items visible.

Questions worth asking before you sign
- Can I see the room-by-room heat-loss calculation?
- What outdoor and flow temperatures did you design for?
- What does the exact proposed model deliver at those conditions?
- Which radiators or emitters need changing, and why?
- What hot-water cylinder and controls are included?
- Exactly what electrical, commissioning, drainage and making-good work is included?
- What assumptions support any efficiency, SCOP or running-cost claim?
- What is the gross installed price before any BUS deduction?
- What warranties, servicing requirements and payment milestones apply?
Current UK grant context
Ofgem states that BUS is installer-led, that eligible installations must meet scheme requirements and that property owners should obtain quotes from multiple installers. Use current Ofgem guidance rather than relying on copied grant wording in a sales quote.

Heat-pump quote FAQs
What should a good heat-pump quote include?
It should make the design assumptions and installed scope inspectable: heat-loss evidence, design temperatures, exact equipment, emitters, hot water, controls, electrical work, commissioning, exclusions and the assumptions behind performance or grant claims.
Why do heat-pump quotes differ so much?
Installers can use different heat-loss assumptions, design temperatures, emitter strategies, equipment and included works. Compare the written design evidence and scope rather than price or nominal capacity alone.
Does a BUS grant deduction prove eligibility?
No. Treat it as a quote assumption until the application-level requirements are confirmed. Check current Ofgem guidance and ask the installer to explain how the proposed installation meets the scheme rules.
Can Home Quote Check prove the heat pump is correctly sized?
No. It compares what the quotes state, highlights conflicts and missing evidence, and generates questions to take back to installers. It is not a heat-loss calculation or installation design certification.
What Home Quote Check does differently: this is not just a checklist. You can add the facts from genuine installer quotes and create a Decision Case showing where proposals conflict, what evidence is missing and what to ask next.
