Heat pump replacement means removing an existing outdoor unit, and sometimes the cylinder and controls, and fitting a new heat pump sized and set up for the home as it is now. Air source heat pumps typically last 15–20 years, so systems fitted when the technology was newer to UK homes are reaching the point where repairs become harder to justify.
Some of the earlier heat pumps in West Yorkshire are now reaching the age where replacement is worth considering. Every replacement in West Yorkshire starts with a fresh heat loss survey, not just a copy of the old unit's size. Across West Yorkshire and West Yorkshire, 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
- Heat pumps nearing the end of their typical life with rising repair costs
- 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 West Yorkshire 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
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.
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.
How long does an air source heat pump last?
Air source heat pumps typically last 15–20 years, depending on the quality of the original design, how hard the unit has worked, where it is sited and how well it has been serviced. Units that short cycle or run at high flow temperatures for years may wear sooner. Annual servicing helps components last and spots problems early.
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.
