Heat pump installation estimate

See what your heat pump installation could cost.

Choose the closest answers for an immediate estimated installation price. You do not need technical measurements; the home survey confirms the final design and price.

Installed heat pump estimate

See your likely installed heat pump cost

Answer a few straightforward questions to see an estimated cost after the government grant. Nimbus then visits to check the home, radiators and hot water before giving you a fixed price. This is not a quote until the survey and design are complete.

We start with a typical 3-bedroom home, mains-gas heating and an existing hot-water cylinder. Change anything that does not match your home. If you are unsure, choose the closest answer - the survey confirms it.

Your postcode helps us allow for local access and installation conditions.

Approximate home size

Where can I find my floor area?

Check your EPC or an old estate-agent floorplan. Rightmove and Zoopla sold-property listings may also show the total floor area. A close estimate is fine for now.

Before you choose

Would a heat pump suit your home?

Start with the rooms, hot water and space you have. The survey turns those details into a system and price you can assess.

Independent advice from Energy Saving Trust
Can a heat pump work in an older home?

Yes, but the design matters more than the age of the house. We assess insulation and room-by-room heat demand before selecting the heat pump and any radiator or pipework changes.

Will I need new radiators or underfloor heating?

Not necessarily. Existing radiators are checked against each room's heat demand at the proposed water temperature. Some may need upgrading; underfloor heating is an option, not a requirement.

Where will the outdoor unit and hot-water cylinder go?

The survey checks outdoor airflow, access, drainage and noise considerations, together with indoor hot-water space. A home replacing a combi boiler may need space for a cylinder.

What should my installation proposal include?

Your proposal sets out the heat pump, hot-water arrangement, radiator or underfloor-heating work, controls, electrical work and installation scope. It explains any grant allowance, exclusions and work needed before installation.

Can I discuss my home without completing the calculator?

Yes. Call Nimbus or request a survey below with your postcode and current heating type. Photos of the existing boiler, cylinder and proposed outdoor position help us prepare for the first conversation.
