Replacing an old outdoor unit like-for-like has a guide price of £6,000–£9,500, installed and including VAT. Where the system needs re-sizing or other upgrades, the written quote sets out each item. Grant funding rarely applies to replacements, because the Boiler Upgrade Scheme in England and Wales cannot usually fund a home already funded for a heat pump, so we check eligibility before quoting.
Homes in Nottinghamshire with a heat pump that never kept them warm can have the whole design checked before a new unit is chosen. Every replacement in Nottinghamshire starts with a fresh heat loss survey, not just a copy of the old unit's size. Across Nottinghamshire and Nottinghamshire, old units are removed with their refrigerant recovered by an F-gas certified engineer.
Who it suits
- Oversized systems that short cycle and cost more to run than expected
- Units that have failed with a major fault, such as a compressor failure
- Older units where parts are becoming hard to source
- Systems that were undersized and struggle in cold weather
Grants and rules for heat pumps in England
Homes in Nottinghamshire can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump replacement questions
Can I get a grant to replace my heat pump?
Usually not. In England and Wales, the Boiler Upgrade Scheme cannot normally fund a home that has already been funded for a heat pump, and it is aimed at replacing fossil-fuel or electric heating. Your circumstances may differ, so we check eligibility before quoting. In Scotland, check Home Energy Scotland's criteria. Northern Ireland has no dedicated grant at present.
What happens to my old heat pump?
The old outdoor unit is removed and disposed of responsibly. Its refrigerant is recovered first, which must be done by an F-gas certified engineer, and metals and components are recycled where facilities allow. If the old cylinder or controls are replaced too, they are removed at the same time, and pipework that is no longer needed is capped or taken out.
Can I replace just the outdoor unit?
Often, yes, if the rest of the system is sound and correctly designed. The cylinder, controls and radiators can stay where they are compatible with the new unit. Some older cylinders and controllers do not work with a new heat pump, and the survey checks this. If the original design was the problem, replacing only the unit will not fix it.
How much does it cost to replace a heat pump?
Replacing an old outdoor unit like-for-like has a guide price of £6,000–£9,500, installed and including VAT. Re-sizing, a new cylinder, radiator upgrades or new controls add to that, and each is itemised in your written quote. The final price is fixed after a survey, once we know what the existing system needs.
