Two heat pump quotes can describe very different projects. The cheaper total may exclude work included elsewhere. Treat price comparison as a scope comparison first: what will each supplier deliver, install and take responsibility for?
1. Ask for an itemised quotation
Request separate entries for the heat pump, cylinder where needed, controls, accessories, materials, labour, delivery and commissioning. Ask whether taxes, removal of old equipment and site reinstatement are included. Mark each item as included, excluded or provisional.
2. Compare the same design
Check the exact model, proposed operating conditions, hot-water provision and any backup heater. Ask why one proposal changes radiators while another retains them. Resolve these design differences before judging the price. Features such as remote control should be assessed against your actual needs, including any recurring fees.
3. Read running-cost estimates carefully
Request the assumed annual heat demand, seasonal system performance and electricity tariff. Ask whether hot water, backup heating and auxiliary consumption are included. Energy Saving Trust notes that bill savings depend on factors including the system being replaced and energy prices.
Do not treat a laboratory efficiency figure as a guaranteed annual bill. Compare estimates using the same assumptions, and ask for a less favourable scenario as well as the expected one. Keep incentives separate from the base price until local eligibility is confirmed.
4. Identify potential additional work
Ask about electrical upgrades, foundations, drainage, pipe routes and emitter changes. For work that cannot yet be priced, request the reason, decision point and pricing method. Agree that additional work needs written approval before it starts.
5. Compare ownership costs and service
Request maintenance requirements, service prices, warranty exclusions and charges for travel, labour or replacement parts. Ask who handles a fault if equipment and installation come from different companies. A longer warranty headline is not a substitute for understanding the coverage.
6. Use this comparison checklist
- Same building brief and design assumptions?
- Exact model and complete accessory list?
- Installation, delivery, taxes and commissioning clearly stated?
- Provisional items and additional-work approval defined?
- Running-cost assumptions consistent?
- Maintenance, warranty and local service responsibilities documented?
The best quote is the one you can understand and verify against your requirements, not automatically the lowest or highest. Contact Thermovo with your project brief and request a clearly defined supply scope.
Before requesting a project quotation
| Check | Information to prepare |
|---|---|
| Project scope | State the country, project type, operating conditions and required delivery date. Identify which decisions still need an installer or designer. |
| Topic-specific evidence | a common quotation scope and a list of exclusions |
| Responsibility and acceptance | Record who supplies, installs, commissions and services the equipment. Ask which documents and checks are included, and confirm exclusions in writing. |
This checklist helps define a request; it is not a model performance claim, installation design or promise of availability.
