THE SHEFFIELD FIELD GUIDE / AIR SOURCE HEAT PUMPS
A sloping plot can change the base, drainage and delivery route for a heat pump. Include those Sheffield site details alongside the room survey.
START WITH THE PROPERTY
If a Sheffield garden has steps or changing levels, show where equipment would be delivered, placed and later serviced. A flat site sketch can conceal ground work and access costs.
BEFORE YOU ACCEPT A QUOTE
Check the position, base, drainage and pipe entry against the heat-loss plan. If the quote excludes lifting equipment or retaining work, resolve that before comparing its total with a fuller proposal.
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 11,826 kWh, the 2024 mean annual domestic gas use per meter in Sheffield. 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 quote assumes a level base and normal trolley access.
Another includes ground preparation, lifting route and drainage at the chosen position.
Check the actual levels and access before comparing totals. A provisional ground-work allowance is a material risk on an otherwise detailed proposal.

Ground works can be priced accurately while heat output is still guessed. A room-by-room heat-loss assessment should support the radiator and hot-water design.
