THE COVENTRY FIELD GUIDE / AIR SOURCE HEAT PUMPS
Moving from a gas boiler changes hot-water storage and the old system's removal. Put both on the Coventry heat-pump scope before judging price.
START WITH THE PROPERTY
For a Coventry home changing from gas, show the existing boiler, cylinder if any, and storage space. The heat pump choice must sit inside a workable plan for hot water and radiator changes.
BEFORE YOU ACCEPT A QUOTE
A complete quotation should price decommissioning, the new cylinder, controls, electrical work and making good. Ask who takes responsibility for the old equipment and for balancing the finished heating system.
LOCAL COST EVIDENCE / OCTOBER 2026
A quoted installation price depends on the work inside the home. Electricity use depends on the finished design and tariff.
We could not verify a representative local average for a fully installed, family-sized system. Published installer figures mix starting prices, example homes and different scopes. Averaging them would suggest more certainty than the evidence allows.
For a useful comparison, ask each installer to itemise the heat pump, cylinder, radiator changes, electrical work and commissioning, then show the price before and after any eligible grant.
about £780approximate annual cost if the October–December 2026 unit rate lasted a full year
This is a model, not a measured bill or an average for families with heat pumps. It starts with 11,117 kWh, the 2024 mean annual domestic gas use per meter in Coventry. We apply 85% boiler efficiency and a heat pump seasonal performance factor of 3.1, then price the electricity at 25.60p per kWh in West Midlands.
Calculation: 2024 mean gas kWh per domestic meter × 0.85 ÷ 3.1 × Ofgem electricity unit rate. The result is rounded to the nearest £10. It assumes the gas meter's entire use was for heating and hot water, so cooking and other gas use can make it too high. It does not include existing electricity standing charges, servicing, or changes to your other electricity use.
Gas consumption is by local authority, except London, which uses the London region. Oxfordshire combines its five districts by gas-meter count. The electricity rate follows the distribution region for the place; Oxfordshire spans two regions. Actual cost depends on your heat-loss survey, hot-water use, chosen tariff, controls and the installed system's measured performance. Ask the installer for a property-specific annual estimate.
ILLUSTRATIVE QUOTE COMPARISON
One price starts at the new heat pump connection.
Another includes decommissioning, cylinder, controls, electrical works and balancing.
Ask each installer to price the same finished state. Otherwise the cheapest figure may leave several trades and a hot-water gap for you to arrange.

NEXT STEP IN COVENTRY
Replacing gas also changes operating temperature. Ask the installer to connect room heat losses, emitter output and proposed flow temperature instead of assuming every radiator can remain.
