How to Price a Heat Pump Installation
Pricing a heat pump is pricing a system, not a box. The number that wins the job and still makes money starts with the heat loss survey and ends with the MCS paperwork — everything in between has to be costed honestly.
The temptation on a heat pump quote is to price the unit, add a day or two of labour, and send it. That is how installers lose money — because the cost of a heat pump job lives in the design, the emitter upgrades, the electrical work and the MCS admin, not in the kit on the pallet.
This guide breaks a heat pump installation into the parts you actually have to cost: the survey and design, the heat pump and cylinder, emitter and pipework upgrades, the electrical supply, commissioning and the MCS and grant paperwork. Price each properly and your quote is defensible when the customer compares it to a cheaper one that has cut corners.
Key takeaways
- A heat pump quote is only as good as the heat loss survey behind it — price the design work in, don't give it away.
- The biggest hidden cost is emitter and pipework upgrades to suit a low flow temperature, so survey for them before you quote.
- Cost the electrical supply and any DNO notification as a line item, not an afterthought.
- MCS certification and the grant admin take real time — build them into the price rather than absorbing them.
- Break the quote into clear stages so the customer sees where their money goes and you can stage the invoicing.
Start by pricing the survey and design
Every heat pump price rests on a room-by-room heat loss calculation to a recognised method. That survey and the design work that follows — emitter schedule, flow temperature, pipework, cylinder sizing — is skilled time, and it is what separates an MCS-standard install from a guess. Cost it as a real part of the job.
A proper survey also protects your margin: it tells you which radiators need upsizing and where the pipework is undersized before you commit to a number, so you are not discovering the expensive parts of the job halfway through the install.
The survey is the quote
Never quote a heat pump from a boiler size or a quick look round. The heat loss survey is what makes the price accurate — and it is a chargeable, valuable piece of work in its own right.
Kit, emitters and pipework
The heat pump, hot water cylinder, buffer or volumiser, controls and sundries are the obvious line items. Less obvious, and often larger, is the cost of getting the emitters to deliver enough heat at a low flow temperature: radiators sized for 70°C water frequently need upsizing, and some rooms may want underfloor heating instead.
Pipework and flow rate have to carry the heat at that lower temperature too, so factor in any upsizing of runs. Use the radiator sizing figures to decide exactly which emitters change — pricing a blanket 'upgrade all radiators' either loses you the job or loses you money.

Electrical supply, siting and access
A heat pump needs a suitable dedicated electrical supply, and in many cases DNO notification because of the load. That is electrical labour and sometimes a supply upgrade — price it as its own line, and involve the electrical requirements early so it is not a commissioning-day surprise.
Siting and access shift the price too: a long condensate run, an awkward outdoor position, scaffolding, or lifting a cylinder into a loft all cost time. Survey for them so the labour figure reflects the real job rather than an ideal one.
Commissioning, MCS and grant admin
Commissioning a heat pump properly — setting the flow temperature and weather compensation, balancing emitters, confirming flow rates — is a genuine block of skilled time, not a token final hour. Under-price it and you either rush it or eat the cost.
Then there is the MCS certification and the Boiler Upgrade Scheme paperwork, which unlocks the grant for the customer. It takes real time to do correctly, and it is part of what your customer is paying for. Build it into the price openly rather than treating it as free admin.
Quote in stages, invoice in stages
TradePlanr lets you build a heat pump quote as clear line items — survey, kit, emitters, electrical, commissioning, MCS — then stage the invoicing across deposit, install and handover, so cash flow follows the work.
Presenting a quote that wins on value
A cheaper competing quote has almost always skipped the survey, kept the old radiators, or skimped on commissioning. Your quote wins by being transparent: show the heat loss design, the specific emitter upgrades, the electrical work and the MCS handover, so the customer understands why the numbers differ.
Break the total into stages the customer can follow, and reference the design that sits behind it. A clear, itemised quote reads as competence, and it makes the eventual handover paperwork feel like the promise being kept rather than an extra.
From guidance to action
Frequently asked questions
Why is one heat pump quote so much cheaper than another?
Usually because the cheaper quote has cut something you can't see: no proper heat loss survey, keeping undersized radiators, minimal commissioning, or skipping the MCS admin. Those shortcuts show up later as poor efficiency and callbacks.
Should I charge for the heat loss survey?
Yes. The survey and the design work that follows are skilled, chargeable work and the foundation of an accurate quote. Giving it away trains customers to see it as worthless and squeezes your margin.
What's the most commonly under-priced part of a heat pump job?
Emitter and pipework upgrades to suit a low flow temperature, closely followed by commissioning and the MCS and grant paperwork. Survey for the emitter changes before you quote so they aren't a nasty surprise.
How should I structure the payment?
Stage it — typically a deposit, a payment at install, and a final payment at commissioning and handover. Staged invoicing keeps cash flow in line with the work and the paperwork you deliver.
