Average Heating Bill in the UK: Costs and Ways to Save

There is no single UK heating bill, as costs vary with home size, insulation, climate, fuel type, and thermostat settings. Based on 10,000kWh of useful heat per year, current Ofgem average rates imply roughly £814 for gas through a 90% efficient boiler, £2,611 for direct electric heating, or about £870 for a heat pump with a seasonal COP of 3.0, before standing charges.

Two neighbours can pay very different amounts to keep similarly sized homes warm. One may have good insulation, a modern boiler, and a steady 20°C thermostat setting, while another may live in a draughty property heated with electric resistance heaters for longer periods each day. A useful estimate therefore starts with how much heat a home needs, then considers how efficiently the heating system delivers that heat and what the fuel costs. This guide explains how to estimate those costs, compares the running costs of common heating systems, and looks at practical ways to reduce your heating bill without sacrificing comfort.

Is There an Average Heating Bill in the UK?

Average heating bill UK figures are difficult to define because household bills combine space heating, hot water, cooking, and electricity for appliances. Ofgem publishes typical domestic consumption values for gas and electricity, but it does not label a fixed portion as "heating" for every home.

A better comparison is to choose a useful heat demand and calculate the fuel required by each system. The examples below use 10,000kWh of delivered heat per year for a representative home. Your EPC or heat-loss survey can provide a more useful estimate for your property.

How Much Does Home Heating Cost in the UK?

The table uses Ofgem's average Direct Debit rates for 1 July to 30 September 2026: 7.33p/kWh gas and 26.11p/kWh electricity. Standing charges are excluded because they apply to the wider fuel account rather than to heating alone.

Gas Central Heating

With a seasonal boiler efficiency of 90%, delivering 10,000kWh of useful heat requires about 11,111kWh of gas. At 7.33p/kWh, the fuel component is roughly £814. Older or poorly controlled boilers can require more gas for the same heat delivered to rooms.

Direct Electric Heating

Resistance heaters turn nearly all metered electricity into heat at the point of use, so 10,000kWh of heat requires about 10,000kWh of electricity. At 26.11p/kWh, that is around £2,611 before standing charges. Storage heaters can lower cost if they charge on a genuinely cheaper off-peak tariff.

Heat Pumps

A heat pump moves heat rather than creating it directly. At a seasonal performance factor of 3.0, 10,000kWh of useful heat requires about 3,333kWh of electricity, costing roughly £870 at 26.11p/kWh. Real seasonal performance depends on design, flow temperature, weather, emitters, and controls.

Heating Oil and LPG

Oil and LPG are purchased by litre or bulk delivery rather than the Ofgem kWh tariff. For a fair comparison, convert litres to usable kWh and apply boiler efficiency. Heating oil contains roughly 10kWh/litre and LPG roughly 6.9kWh/litre as planning values.

*Gas/electricity use Ofgem average Direct Debit rates for 1 Jul-30 Sep 2026; oil/LPG prices are illustrative market ranges, not regulated tariffs. Standing charges and maintenance are excluded.

How to Estimate Your Own Heating Bill

Use your own meter data where possible. A winter-to-summer comparison can help separate heating from year-round hot-water or cooking use.

Identify the Energy Used for Heating

For gas heating, compare annual gas consumption and estimate the non-heating baseline from summer months. For electric heating, smart-meter half-hourly data can show heater periods. Heat-pump controls may report compressor electricity and delivered heat separately, although accuracy varies by system.

Multiply Usage by the Unit Rate

If heating-related gas use is 12,000kWh and the unit rate is 7.33p/kWh, the variable energy cost is about £880. If electric heating uses 4,000kWh at 26.11p/kWh, it costs about £1,044. Add the relevant portion of standing charges only if you are comparing total fuel-account cost.

Account for System Efficiency

Fuel input is not the same as useful heat. A 90% efficient boiler needs about 1.11kWh of gas for 1kWh of delivered heat. A heat pump with seasonal COP 3 needs about 0.33kWh of electricity per 1kWh of delivered heat. Efficiency is therefore central to any fair comparison between heating systems.

What Affects Your Heating Bill?

Heating bills winter UK households can vary sharply with the weather, but your property's construction and heating controls also determine the baseline.

Property Size and Insulation

More external wall, roof, and floor area creates more heat-loss surface. Insulation and airtightness reduce the heat flow for a given indoor-outdoor temperature difference. An efficient small flat can need a fraction of the heat required by a large detached house.

Thermostat Settings and Heating Hours

Every extra degree of indoor temperature increases heat loss, while longer heating periods increase overall energy use. Energy Saving Trust recommends the lowest comfortable temperature, usually 18–21°C, and says reducing a thermostat from 22°C to 21°C can save around £90 a year in Great Britain.

Weather and Location

A cold, windy winter creates more heating demand than a mild one. Exposed rural properties can also experience greater heat loss through air infiltration. Compare several years of bills before concluding that a single winter represents your normal baseline.

System Efficiency and Maintenance

Boiler flow temperature, heat-pump commissioning, radiator balance, filters, and controls all affect how efficiently energy becomes comfort. Energy Saving Trust notes that reducing a combi-boiler flow temperature toward 60°C can improve efficiency where the home still heats adequately.

How to Reduce Your Heating Bill

How to cut your heating bills? This is mainly a question of reducing heat loss and avoiding heat when it is not needed. Start with controls and draughts before major capital work.

Use Heating Controls More Effectively

Programme heating around occupancy, use thermostatic radiator valves to avoid overheating spare rooms, and set the main thermostat sensibly. If you are wondering how to reduce heating bill without losing comfort, accurate zoning is often more sustainable than simply turning the whole system off.

Lower Boiler Flow Temperature When Suitable

A combi boiler may run more efficiently at a lower radiator flow temperature because it can condense more effectively. Energy Saving Trust discusses around 60°C as a reasonable starting point for many combi systems, adjusted gradually for comfort. Do not apply this blindly to a conventional boiler with a hot-water cylinder.

Draught-Proof Doors and Windows

Energy Saving Trust estimates draught proofing around windows, floors, and doors can save around £55 a year in Great Britain. Keep intentional ventilation open, especially in rooms with combustion appliances or moisture risk.

Improve Insulation

Loft, wall, and floor insulation reduce heat demand every heating hour. The best measure depends on construction and existing insulation. Have the property assessed rather than assuming the same upgrade will suit a 1930s cavity-wall house and a solid-wall Victorian terrace.

Maintain the Heating System

Service boilers and heat pumps to manufacturer schedules, bleed and balance radiators where appropriate, keep heat-pump outdoor units clear, and fix faulty thermostats. A system that can not distribute heat properly often encourages higher setpoints and longer run times.

Make Better Use of Solar and Stored Energy

If you have solar PV or an off-peak electricity tariff, stored energy can shift some electrical heating-support loads away from expensive periods. This is more practical for a heat pump, circulation pumps, or household loads than for trying to run a whole resistance-heated home from a small battery.

The BLUETTI Home Battery Backup Collection offers practical energy storage solutions for households looking to make better use of solar power, shift electricity use to cheaper periods, and maintain essential power during outages.

For a concrete example, BLUETTI Apex 300+B300K combines an Apex 300 with a B300K to provide 5,529.6Wh of total storage and 3,840W of output. This capacity can help shift selected electrical loads to cheaper periods or solar-generation hours while supporting a heat pump and other essential home appliances during short power interruptions.

What Government Support Is Available for Heating Costs?

Support changes by nation, income, tenure, heating technology, and year. The Warm Home Discount remains a separate £150 electricity-bill discount for eligible households, while England, Scotland, Wales, and Northern Ireland each have different home-energy upgrade programmes. Heat-network customers in Great Britain also gained new Ofgem consumer protections in 2026.

The heat metering and billing regulations framework also changed in 2026. Ofgem became the Great Britain heat-network regulator, while parts of the older Heat Network (Metering and Billing) Regulations were revoked or superseded.

Conclusion

There is no single average heating bill that describes every UK home. A useful estimate starts with heat demand, divides by system efficiency, and applies a dated fuel price. At current Ofgem average rates, direct electric resistance heating is much more expensive per unit of useful heat than gas or a well-performing heat pump.

FAQs

Is Gas Heating Cheaper Than Electric Heating?

At the current average price-cap rates, gas is much cheaper per purchased kWh than electricity. Even after allowing for boiler losses, a gas boiler can deliver heat at a lower variable fuel cost than direct electric resistance heating.

How Much Does It Cost to Heat a House for One Hour?

It depends on the heat output required. A 10kW gas boiler delivering heat at 90% efficiency might burn about 11.1kWh of gas in a full-output hour, around 81p at 7.33p/kWh. A 2kW electric heater costs about 52p/hour at 26.11p/kWh. Most systems cycle rather than run at full output continuously.

Is It Cheaper to Leave the Heating On All Day?

For a typical gas-boiler system, keeping an empty home at a higher temperature all day usually uses more energy than heating it when needed because heat loss continues whenever the indoor temperature is above outside. Heat pumps can be different: steady lower-temperature operation may be more efficient than aggressive on-off schedules.

What Temperature Should I Set My Thermostat To?

Energy Saving Trust recommends the lowest comfortable temperature, typically 18-21°C for most people. Health needs vary, so comfort and safety come first. Its 2026 guidance indicates that reducing the setting from 22°C to 21°C can save around £90 a year in Great Britain in a typical home.
