Understanding UK home energy use is essential context for retrofit policy, fuel poverty analysis and decarbonisation planning. This page summarises UK home energy statistics for 2026 covering typical household consumption, the fuel mix used for space and water heating, regional variations and the count of off-gas-grid households. Figures are drawn from ONS, BEIS sub-national consumption data and Ofgem reporting.
Average UK household consumption
Ofgem's Typical Domestic Consumption Values (TDCVs), used to define standard household energy bills, were updated in 2023. Approximate UK average household energy consumption (medium-use household):
| Fuel | Typical annual consumption (medium-use household) |
|---|---|
| Electricity (single-rate) | ~2,700 kWh |
| Gas | ~11,500 kWh |
| Total household energy (gas + electricity, gas-heated) | ~14,200 kWh |
| Heating oil (off-gas household) | ~17,000-23,000 kWh equivalent |
Real-world consumption varies widely with property size, occupancy, EPC band and heating system efficiency. A heat-pump-heated household typically uses approximately 4,500-7,500 kWh of electricity annually for space and water heating combined, replacing the equivalent gas consumption.
Fuel mix for space and water heating
According to BEIS/DESNZ housing energy data, approximate fuel mix for primary space and water heating across UK dwellings is as follows:
| Heating fuel/system | Approximate share of UK dwellings |
|---|---|
| Mains gas (boiler / combi) | ~78-80% |
| Electric storage heaters / electric panel | ~7-9% |
| Heating oil | ~4-5% |
| LPG | ~1-2% |
| Solid fuel (coal/biomass) | ~1% |
| Heat pump (ASHP/GSHP) | ~1-2% (rising) |
| District/communal heating | ~2-3% |
Regional variations in consumption
BEIS sub-national consumption data shows clear regional variation, driven by climate, dwelling type and tenure mix. Approximate average annual gas consumption per household by UK nation/region (medium-use):
| Nation/Region | Approximate average household gas consumption (kWh) |
|---|---|
| England (national average) | ~11,400 |
| North East | ~12,500 |
| North West | ~12,000 |
| Yorkshire & Humber | ~11,800 |
| East Midlands | ~11,600 |
| West Midlands | ~11,500 |
| South East | ~11,200 |
| South West | ~10,800 |
| East of England | ~11,100 |
| London | ~10,200 |
| Wales | ~11,800 |
| Scotland | ~13,000 |

EPC band distribution and energy use
EPC band correlates strongly with household energy consumption. Approximate medium-use household consumption by EPC band:
| EPC band | Approximate annual primary energy use (kWh/m²) | Indicative annual heating cost (gas-heated) |
|---|---|---|
| A/B | ~50-90 | £500-£750 |
| C | ~90-150 | £750-£1,100 |
| D | ~150-220 | £1,100-£1,500 |
| E | ~220-310 | £1,500-£2,100 |
| F/G | ~310+ | £2,100+ |
Indicative costs use the 2024-2025 gas price cap and assume a typical 90m² dwelling.
Off-gas-grid household count
Approximately ~2.0 million UK households are off the mains gas grid, of which:
- Heating oil-heated households: approximately ~1.0-1.1 million
- LPG-heated households: approximately ~150,000-200,000
- Electric-only heated households (off-gas): approximately ~500,000-700,000
- Solid fuel and other: approximately ~150,000
Off-gas households are concentrated in rural Scotland, Wales, Northern Ireland and rural English regions. Heat pump uptake under BUS is disproportionately strong among off-gas households because the alternative fuel cost economics favour electrification.

Trends in UK household energy use
Long-run UK household energy use has trended downward since around 2005, driven by boiler efficiency upgrades, cavity wall and loft insulation programmes and the gradual shift away from solid fuel. Headline trends:
- Average household total energy use (gas + electricity, gas-heated): down approximately 20-25% since 2005
- Average household electricity use: down approximately 15% since 2010, driven by lighting/appliance efficiency
- Average household gas use: down approximately 20% since 2005, partially reversed by colder winters
- Heat pumps and EV charging are starting to push residential electricity demand back upward in highly electrified households
UK domestic gas and electricity supplier market
The UK domestic energy retail market is concentrated among a small number of major suppliers. Approximate domestic supply market shares as of 2024-2025:
| Supplier | Approximate domestic supply share |
|---|---|
| Octopus Energy (incl. Bulb book) | ~24-26% |
| British Gas / Centrica | ~18-20% |
| OVO Energy (incl. SSE retail) | ~13-15% |
| EDF Energy | ~10-12% |
| E.ON Next | ~10-12% |
| ScottishPower | ~7-9% |
| Other licensed suppliers | ~6-10% |
Source: Ofgem retail market data; shares fluctuate with customer migration and the periodic exit/merger of smaller suppliers.
Average annual energy spend by income decile
Energy spend as a share of household income varies sharply across the income distribution. Approximate UK distribution based on ONS and BEIS analysis:
| Income decile | Approximate annual energy spend (GBP) | Approximate share of household income |
|---|---|---|
| Bottom 10% (decile 1) | £1,500-£1,900 | ~14-18% |
| Decile 2 | £1,500-£1,950 | ~10-12% |
| Decile 3 | £1,600-£2,000 | ~7-9% |
| Mid (decile 5-6) | £1,750-£2,200 | ~4-6% |
| Decile 8-9 | £2,000-£2,500 | ~3-4% |
| Top 10% (decile 10) | £2,300-£2,800 | ~2-3% |
Figures use the 2024-25 price cap and approximate ONS Living Costs and Food Survey data.
The disproportionate burden on low-income households underpins both fuel poverty policy and the supplier obligation funding model used under ECO.
Cooking, hot water and appliance fuel breakdowns
UK domestic energy use is dominated by space heating but the breakdown by end-use is informative for retrofit prioritisation. Approximate UK domestic energy consumption by end-use:
| End-use | Approximate share of household energy consumption |
|---|---|
| Space heating | ~60-65% |
| Hot water | ~16-18% |
| Cooking | ~3-4% |
| Lighting | ~2-3% |
| Cold appliances (fridges, freezers) | ~3-4% |
| Wet appliances (washing machines, dishwashers) | ~3-4% |
| Consumer electronics, IT, entertainment | ~5-7% |
| Other (small power, garden, miscellaneous) | ~2-4% |
Source: BEIS energy consumption in the UK, latest published year. Shares vary modestly by region and dwelling type.
Space heating's dominance is the reason heat pump and insulation policies command the largest share of UK retrofit funding. Lighting and appliances have already delivered material consumption reductions through efficiency standards over the past 15 years.
Heating degree days and consumption variation
UK heating energy demand correlates closely with heating degree days (HDD), the standard climate-corrected metric. Approximate HDD figures by region for a base temperature of 15.5C:
| Region | Approximate annual HDD (15.5C base) |
|---|---|
| South West England | ~1,600-1,750 |
| South East England | ~1,750-1,850 |
| London | ~1,650-1,750 |
| Midlands | ~1,950-2,100 |
| North England | ~2,100-2,300 |
| Wales (varies elevation) | ~2,000-2,300 |
| Scotland (lowlands) | ~2,400-2,700 |
| Scotland (highlands) | ~2,800-3,200 |
HDD figures are approximate climatological averages; year-to-year variation can be ~10-15%.
Year-on-year variation in HDD is one of the largest drivers of national gas demand swings; the relatively mild winters of 2023-24 and 2024-25 contributed to the post-2022 decline in residential gas consumption.
Smart meter rollout and time-of-use tariff data
Smart meter coverage is a critical enabler of time-of-use tariffs and demand response. Approximate UK smart meter installation status:
- Total UK domestic smart meters installed: approximately ~36-38 million (gas + electricity combined)
- Smart meter coverage of UK households: approximately ~65-70% of domestic supply points
- SMETS2 share of installed base: approximately ~75-80%
- Households on time-of-use tariffs: approximately ~1.5-2.0 million
- Octopus Agile and similar half-hourly tariffs: estimated at ~250,000-400,000 households
Time-of-use tariffs have become a meaningful adjunct to solar PV and battery installations, with active price-following households reportedly saving an estimated 20-40% on import costs.
EV charging impact on household electricity
EV ownership materially shifts household electricity consumption. Approximate annual EV-related domestic electricity demand:
| Annual EV mileage | Approximate annual home charging demand |
|---|---|
| 5,000 miles | ~1,500 kWh |
| 8,000 miles | ~2,400 kWh |
| 12,000 miles | ~3,600 kWh |
| 15,000 miles | ~4,500 kWh |
UK EV registrations passed approximately ~1.5 million by end-2024 with around ~1.2 million battery-electric vehicles. EV-driving households can effectively double their electricity import without active management; EV-aware tariffs and solar/battery integration substantially mitigate the cost impact.
Energy bills and price cap context
UK domestic energy prices fluctuated sharply during 2022-2024 driven by wholesale gas prices. Approximate Ofgem default tariff price cap levels for a typical dual-fuel household:
| Period | Approximate annual dual-fuel cap (medium use) |
|---|---|
| Q4 2021 | ~£1,277 |
| Q4 2022 (with EPG) | ~£2,500 (govt-supported) |
| Q1 2023 | ~£3,280 (cap), £2,500 (EPG) |
| Q3 2023 | ~£2,074 |
| Q3 2024 | ~£1,568 |
| Q1 2025 | ~£1,738 |
| Q2 2025 | ~£1,849 |
Source: Ofgem default tariff price cap announcements. Figures are typical medium-use household; individual bills vary.
The post-2022 step-up in energy prices materially improved retrofit payback economics relative to the pre-2022 baseline, contributing to the BUS, ECO4 and solar PV uptake observed across 2023-2025.
Fuel poverty in UK households
Fuel poverty data is published separately for England, Scotland, Wales and Northern Ireland under different methodologies. Approximate UK-wide fuel poverty headline figures (most recent reporting):
- England (Low Income Low Energy Efficiency definition): approximately ~13% of households (~3.2 million)
- Scotland (10% of household income on energy): approximately ~24-31% of households
- Wales: approximately ~14% of households
- Northern Ireland: approximately ~22% of households
Fuel poverty is concentrated in band D-G properties, off-gas-grid households and lower-income tenures. ECO4 LA Flex routes are designed to reach this population.
Data caveats
The following caveats apply to UK home energy use statistics:
- Ofgem's TDCVs are statistical averages and individual household use varies widely with occupancy and dwelling size.
- BEIS sub-national consumption data lags real-time use by 12-18 months and is restated periodically.
- Heating oil and LPG household counts are estimated from sales and survey data; the figures lack the granularity of metered fuel data.
- EPC band consumption ranges are indicative; SAP-modelled energy use can differ from real metered consumption.
- Off-gas-grid totals exclude properties with mains gas but using a non-gas heating system as primary.
- Fuel poverty figures use different methodologies across UK nations and are not directly comparable.
UK home energy use has fallen materially since the mid-2000s thanks to insulation, boiler upgrades and appliance efficiency, but mains gas still heats roughly four out of five UK dwellings and around two million households remain off-grid. The combination of EPC band distribution, fuel mix, regional variation and persistent fuel poverty in around 13-30% of households (depending on nation) defines the size and shape of the UK retrofit task ahead.
