THE YORK FIELD GUIDE / AIR SOURCE HEAT PUMPS
The outdoor unit needs a position an engineer can reach later. For a York home with a tight yard, ask how delivery, maintenance and neighbour-facing sound will work.
START WITH THE PROPERTY
A York home may have a viable patch for an outdoor unit but no straightforward delivery or service route. Photograph gates, steps and boundary walls as well as the unit position, so the installer can price the real job.
BEFORE YOU ACCEPT A QUOTE
A quiet-looking location is only useful if pipework can reach the heating system and engineers can maintain the unit. Ask for the chosen position, pipe route, noise assessment and heat-loss design together.
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 £820approximate 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 11,727 kWh, the 2024 mean annual domestic gas use per meter in York. We apply 85% boiler efficiency and a heat pump seasonal performance factor of 3.1, then price the electricity at 25.46p per kWh in North Eastern England.
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
A compact unit is drawn in the rear yard without a delivery or service route.
Another proposal uses the side return and includes the gate, base and pipe run in its price.
Measure the route and ask how each unit will be delivered and maintained. A viable position on a plan is not yet a buildable installation.

An EPC and current fuel bills are useful background; a room-by-room heat-loss survey decides the design. Tell us if you already have one so we can avoid asking for the same work twice.
