Gas vs Electric Heating Costs 2026: Real Price Calculator for Your Home
Gas Heating Remains Significantly Cheaper Than Electric in 2026
With gas heating costing approximately 5.93p per kWh compared to 27.69p per kWh for electricity under the current Ofgem price cap, gas remains nearly 4.7 times less expensive per unit of energy consumed[3][5]. However, the right choice for your home depends on installation costs, property insulation, and your specific usage patterns.
The latest quarterly price cap adjustment brought welcome relief to households, with energy bills falling 7% from 1 April 2026, reducing the typical dual-fuel household bill to £1,641 per year[3][4][7]. This creates an opportune moment to reassess whether your current heating fuel offers the best value.
Current Energy Prices Under the Ofgem Cap
From 1 April to 30 June 2026, the Ofgem energy price cap sets these rates[3]:
| Fuel Type | Unit Rate (p/kWh) | Daily Standing Charge (p) | Annual Standing Charge (£) |
|---|---|---|---|
| Gas | 5.93 | 35.09 | 128.08 |
| Electricity | 27.69 | 54.75 | 199.84 |
These figures form the foundation for any accurate cost comparison, but the true picture emerges when you factor in consumption patterns, system efficiency, and installation costs.
2026 Heating Cost Comparison: Gas vs Electric Systems
| Heating System | Unit Rate (p/kWh) | Daily Standing Charge (p) | Installation Cost (£) | Annual Running Cost (£) |
|---|---|---|---|---|
| Gas Central Heating | 5.93 | 35.09 | 5,250 | 708 |
| Electric Heating | 27.69 | 54.75 | 3,790 | - |
| Heat Pump (Heating) | 27.69 | 54.75 | - | 840 |
| Heat Pump (Hot Water) | 27.69 | 54.75 | - | 190 |
Based on average annual gas consumption of 11,808 kWh, gas heating systems cost approximately £708 to run each year[1]. Electric heating systems, operating at the significantly higher electricity rate, cost roughly four times more per unit of energy consumed[1][2].
Installation Costs: Electric Wins Upfront, Gas Wins Long-Term
Installation costs present a key consideration for households switching heating systems[1]:
- Gas central heating: £4,500 to £6,000 (average £5,250)
- Electric heating: £3,230 to £4,350 (average £3,790)
Electric systems cost approximately £1,460 less to install on average, but this upfront saving gets overwhelmed by substantially higher operational costs. For most UK homes, gas heating proves more economical over the long term, with lower per-unit fuel costs compensating for higher installation expenses within 7-10 years[2].
How to Calculate Your Personal Heating Costs
To determine which fuel type suits your specific situation, follow these steps:
Step 1: Find your annual consumptionCheck your energy bills for annual kWh usage. If switching from one fuel type to another, estimate based on your home size and insulation quality.
Step 2: Apply current ratesMultiply your consumption by the relevant unit rate, then add annual standing charges:
- Gas: (Annual kWh × 0.0593) + £128.08
- Electricity: (Annual kWh × 0.2769) + £199.84
Step 3: Account for efficiencyGas boilers typically operate at around 90% efficiency, while electric systems achieve nearly 100% efficiency. However, the significant price difference per unit more than compensates for this efficiency gap in most scenarios.
Services like Lodo can help you navigate supplier options and handle the switching process once you've determined your preferred fuel type, comparing tariffs across providers to ensure you get the best available rates.
Factors That Influence Your Heating Costs
Property Insulation and Size
Well-insulated homes require less energy overall, reducing the cost advantage of gas heating. However, larger properties or those with poor insulation heavily penalize electric heating due to higher energy demands[2].
Seasonal Variations and Usage Patterns
Winter heating peaks affect both fuel types, but gas maintains its cost advantage throughout the year. The 7% reduction in energy bills from April 2026 benefits both fuels, though gas users see amplified savings due to their higher consumption volumes[6].
Hot Water Provision
Annual hot water costs add approximately £190 for heat pump systems and £210 for gas boilers under 2026 pricing[6]. This relatively small difference shouldn't drive your decision, but it contributes to the overall cost picture.
Maintenance and Service Considerations
Annual servicing costs provide additional context for long-term budgeting[6]:
- Gas boilers: £80-£120 annually
- Electric systems (heat pumps): £100-£150 annually
These differences are relatively minor compared to fuel cost variations, but gas systems edge ahead slightly on maintenance expenses as well.
Making Your Decision: Gas vs Electric in 2026
For most UK households with typical energy consumption and average home insulation, gas heating delivers significantly lower total costs in 2026. The combination of cheaper fuel rates at 5.93p per kWh, reasonable installation expenses, and lower maintenance requirements creates a compelling case for gas.
Electric heating makes sense primarily for:
- Small, exceptionally well-insulated properties
- Homes where gas supply installation is impractical or expensive
- Properties using renewable electricity generation
Gas heating suits:
- Most UK homes with average or poor insulation
- Larger properties with higher heat demand
- Households prioritizing predictable, lower running costs

Is gas cheaper than electric heating in 2026?
Gas is cheaper than electric heating in 2026, with unit prices at 5.93p/kWh for gas and 27.69p/kWh for electricity under the Ofgem price cap from April to June 2026[3][6]. Annual running costs for gas boilers average £708-£890, while electric boilers cost around £1,700 for a typical home[1][4]. Efficiency and insulation further favor gas in most setups.
How to use a gas and electric calculator for 2026 costs?
Use a gas and electric calculator with Ofgem's 2026 rates: gas at 5.93p/kWh and electricity at 27.69p/kWh, plus standing charges of 35.09p and 54.75p daily[3]. Multiply your home's annual kWh usage (e.g., 11,808kWh gas) by unit rates, add standing charges, and factor in boiler efficiency (gas ~90%, electric 100%)[1][4]. Tools from suppliers like British Gas or Octopus adjust for gas vs electric usage patterns.
