THE LEEDS FIELD GUIDE / AIR SOURCE HEAT PUMPS
Insulation installed last year changes the evidence behind a heat-pump quote. Share the work and fuel use with the surveyor for your Leeds home.
START WITH THE PROPERTY
If a Leeds home recently gained insulation or new glazing, a year of fuel use describes two different versions of the building. Give dates and specifications where known, so the surveyor can interpret both bills and room measurements.
BEFORE YOU ACCEPT A QUOTE
Ask whether planned fabric upgrades are included in the heat-loss calculation. If they are, understand what happens to emitter sizes and running estimates if the work is delayed or not completed.
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 £830approximate 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 11,805 kWh, the 2024 mean annual domestic gas use per meter in Leeds. 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 Yorkshire.
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 design sizes emitters for the home as it stands.
Another assumes a scheduled insulation upgrade will reduce the room loads.
Keep the upgrade date and specification beside both calculations. If it slips, you need to know which radiators and running estimates change.

If insulation changes lower the space-heating load, hot-water demand still needs its own design. Show existing cylinder space and how many people the system must serve.
