Gas vs Electric Heating Costs: Which Fuel Type Saves You Money in 2026

Understanding Your Energy Bill Components in 2026

Your energy bill is built from three main components: unit rates (what you pay per kilowatt-hour of energy used), daily standing charges (fixed daily fees), and your actual consumption patterns. The difference between gas and electricity costs has remained significant in 2026, with electricity typically costing much more per unit than gas.

Under the Ofgem price cap for January to March 2026, electricity costs 27.69p per kWh while gas costs just 5.93p per kWh^[3]. This substantial difference means gas remains the cheaper option for heating, cooking, and hot water in most UK homes.

2026 Tariff Rates and Price Cap Details

The Ofgem price cap for standard variable tariffs sets the maximum rates suppliers can charge Direct Debit customers across England, Scotland, and Wales. For January to March 2026, the rates include 5% VAT:

• Electricity: 27.69p per kWh with a 54.75p daily standing charge
• Gas: 5.93p per kWh with a 35.09p daily standing charge

These rates result in an annual bill of £1,758 for a typical dual-fuel household with medium usage, representing a 1% increase (£20) from the previous period but still 2% lower year-on-year after adjusting for inflation^[3].

The good news is that prices are forecast to decrease through 2026, with bills expected to drop to £1,641 between April and June, and £1,637 from July to September^[2].

How Major Suppliers Compare

EDF standard tariff charges align closely with the price cap. Their Standard Variable tariff costs around £147 monthly or £1,765 annually with no exit fees^[1]. ScottishPower offers both standard variable and Cap Tracker tariffs that track below the cap, with prices set to drop from 1 April 2026 across all their tariffs^[2].

Gas vs Electric: Real Cost Differences for Home Energy Use

What's cheaper gas or electric? For heating, cooking, and hot water, gas wins decisively due to the unit rate difference. Here's how the costs break down for typical household uses:

Heating Costs

Gas central heating costs approximately 4-6p per kWh when accounting for boiler efficiency, while electric heating (storage heaters or direct electric) costs 25-30p per kWh^[3]. For an average home, this translates to annual savings of £500-£1,000 when using gas instead of electric heating^[6].

Cooking Costs

Gas hobs and ovens operate at around 6p per kWh, while electric induction cooking costs approximately 28p per kWh^[3]. Gas offers better value for households that cook frequently, though the overall impact on bills is smaller than heating costs.

Hot Water Costs

A gas combi boiler heats water at roughly 6p per kWh, compared to 28p per kWh (or more for inefficient systems) for electric immersion heaters^[3]. Gas remains preferable unless you have very low hot water usage.

When Electric Tariffs Make Sense

While gas generally offers better value, some electric tariffs can work for specific situations. The Scottish Power Economy 7 tariff provides cheaper night-time rates for seven hours (ideal for storage heaters or EV charging) but charges higher day rates^[4]. This tariff only makes financial sense if more than 40% of your electricity usage occurs during the cheaper night period^[6].

If you're considering whether to switch to Scottish Power, their tariffs come with no exit fees for changes within their own range, and their Cap Tracker consistently stays below the price cap^[2]. They also offer fixed-rate options for those wanting price certainty, though early exit fees may apply to these^[5].

Average UK Household Energy Usage

How many kW does a house use varies significantly, but average UK homes consume around 2,700 kWh of electricity and 8,000-12,000 kWh of gas annually^[3]. This medium usage profile typically results in dual-fuel bills of approximately £1,700 under current price caps.

Peak demand for a whole house ranges from 5-10 kW, while the daily average works out to about 7.4 kWh for electricity (roughly 0.3 kW average power)^[3]. Your actual bills will depend on your chosen tariff, meter type, and energy habits.

Making Smart Switching Decisions

When comparing energy deals, start with Ofgem-capped standard variable tariffs as your baseline, then examine fixed-rate deals for price certainty. Dual-fuel tariffs from the same supplier often simplify billing and may offer small discounts.

Services like Join Lodo can handle the switching process for you, comparing tariffs and managing the paperwork while you focus on understanding which fuel type best suits your household needs.

For accurate comparisons, use smart meters to track your actual usage patterns. Some suppliers like ScottishPower offer additional perks for smart meter customers^[5].
