THE NOTTINGHAM FIELD GUIDE / AIR SOURCE HEAT PUMPS
Two heat-pump prices can hide different radiator and electrical scopes. For a Nottingham home, ask which enabling works each design includes.
START WITH THE PROPERTY
For a Nottingham home, list existing radiators and any rooms that already struggle to heat. A heat-loss survey may call for new emitters or electrical work that a short equipment quote does not reveal.
BEFORE YOU ACCEPT A QUOTE
Put the room-by-room emitter plan beside the price. If a radiator or consumer-unit change appears in one offer but not another, ask whether it was judged unnecessary or simply omitted.
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.

This is a model, not a measured bill or an average for families with heat pumps. It starts with 11,046 kWh, the 2024 mean annual domestic gas use per meter in Nottingham. We apply 85% boiler efficiency and a heat pump seasonal performance factor of 3.1, then price the electricity at 25.36p per kWh in East 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 leaves the upstairs emitters and specifies a higher flow temperature.
Another enlarges them to allow lower-temperature operation.
Put room losses and emitter outputs side by side. Compare upfront work with the stated seasonal performance, using the same comfort target.

Emitter upgrades are only part of a full replacement. Request cylinder sizing, controls and any electrical work in the same quotation so the final scope can be compared.
