What should a heat pump quote include?

A heat pump quote is a design, not just a price. If it does not say how big the heat pump is, why it is that size, which radiators change and what happens to the old boiler, the price means very little, and the gaps turn into extras later.

Checked 18 October 2026. This is the checklist our free check uses when it reads your quote.

Six things a fair quote lists

1. A heat loss survey. The size of the heat pump, and of the radiators, should come from a room-by-room heat loss calculation of your house, not from the floor area or the old boiler's size. If the quote does not mention one, the size is a guess. Homes built before 2007 may also need SEAI's technical assessment before the grant is approved.
2. A hot water cylinder. Heat pumps heat water more slowly and at a lower temperature than a boiler, so they need a larger, well-insulated cylinder. Most retrofits replace the existing one; the quote should say whether yours is included and what size.
3. Radiator upgrades, named. A heat pump runs at a lower flow temperature, so some radiators need to be bigger. The quote should say which rooms, or state that the survey found the existing radiators adequate at the design flow temperature. "Radiators as required" is not an answer. This is also what unlocks the €2,000 central heating part of the grant.
4. Removing the old boiler, and the oil tank if you have one. From 6 October 2026 removing an oil or gas boiler earns the €2,000 boiler scrappage grant, so the quote should be clear it is included.
5. Controls. Which thermostats and controller, and whether they let you schedule hot water for a night rate. This is where much of the running cost saving is won or lost.
6. The warranty, in writing. Separately for the heat pump unit and for the installation work, with who to call if it breaks.

Beyond those six, a complete quote names the make, model and rated output of the heat pump, states whether the price is the full price or the price with the grant already deducted, and says whether it is fixed.

Red flags

• No heat loss survey, or a size chosen from the boiler's output. Boilers are routinely oversized; copying that size into a heat pump gives a unit that cycles on and off and costs more to run.
• No make, model or kilowatt figure. You cannot compare two quotes, or check the unit's efficiency, without them.
• "Price subject to survey." The survey should come before the price.
• Grant status unclear. "After grant" with no grant figure, or a grant figure from before October 2026 when the boiler scrappage part was added. The grant page has the current breakdown.
• Not SEAI-registered, or the registration is in another company's name. No registration, no grant.
• Pressure to start before the grant offer arrives. Work started before SEAI's written offer is not funded, and that loss is yours, not the installer's.
• A price far from SEAI's medians with nothing in the scope to explain it. The cost page has the medians by type of home; our check does the comparison for you.

Eight questions to ask before you sign

1. Can I see the heat loss calculation, room by room, that the size is based on?
2. Which make and model of heat pump, and what is its rated output at −3°C outside?
3. Which radiators will you replace, and what flow temperature is the system designed for?
4. Is a new hot water cylinder included? What size?
5. Is removing the old boiler and oil tank included?
6. Are you SEAI-registered, and will you handle the grant paperwork?
7. What warranty do I get on the unit and on your work, and who do I call if it breaks?
8. Is the price fixed, or can extras be added once work starts?

A good installer answers all eight without hesitation, because the answers are in their design. An installer who gets defensive about the first one is telling you something.
