Wood Burning Stove vs Central Heating: 2026 UK Cost Comparison

Wood Burning Stove vs Central Heating: 2026 UK Cost Comparison

Updated: May 2026 — Power Guardian UK Editorial Team

Are log burners still cheaper than gas central heating in 2026? Real costs, Defra rules and savings explained. This guide gives you the latest 2026 unit rates, real-world UK examples and a clear bottom line so you can decide what's right for your home.

Quick answer

Under the April 2026 Ofgem price cap, electricity costs around 27p per kWh and gas around 6.5p per kWh for a typical UK direct-debit customer. Standing charges are about 60p/day for electricity and 31p/day for gas. We use those figures throughout this article — your exact rates will be on your latest bill.

The 2026 cost numbers that matter

These are national averages. Northern Scotland, North Wales and the South West tend to be 5–10% above the average; East Midlands is usually cheapest.

A worked UK example

Take a typical 3-bed semi in the Midlands using 2,700 kWh of electricity and 11,500 kWh of gas a year. At April 2026 cap rates:

• Electricity: 2,700 × £0.27 = £729 + 365 × £0.60 = £219 standing → £948
• Gas: 11,500 × £0.065 = £748 + 365 × £0.31 = £113 standing → £861
• Total: £1,809/year (slightly above the headline because Ofgem uses slightly lower assumed unit rates in its TDCV calc)

The main mistakes UK households make

1. Comparing only unit rates — standing charges add over £330/year before you switch on a single light.
2. Ignoring the small print — exit fees of £50/fuel are still common on fixed deals in 2026.
3. Sticking on the price cap by default — fixed deals from Octopus, EDF and OVO have averaged 4–8% below the cap throughout early 2026.
4. Forgetting Warm Home Discount — £150 in 2026 if you're on certain benefits, applied automatically by most suppliers.
5. Not submitting meter readings — even smart meters drift; one missed reading can mean a £200 catch-up bill.

What to do next

1. Find your latest bill or app and write down your unit rate and standing charge for both fuels.
2. Multiply your last 12 months of kWh by the figures above to sanity-check what you'd pay on the cap today.
3. Run a comparison on a whole-of-market site (or our bill calculator) and look for a fix at least 3% below your current rate.
4. If you're vulnerable, in fuel poverty or on benefits, check the Warm Home Discount and Priority Services Register.
5. Submit a meter reading on the day your tariff changes.

How often do UK energy prices change in 2026? The Ofgem price cap is reviewed every 3 months (January, April, July, October). Fixed deals stay the same for the length of your contract — usually 12 or 24 months.

Is the price cap a maximum bill? No — it caps unit rates and standing charges, not your total bill. Use more energy and you pay more.

Should I fix my tariff in 2026? Most independent forecasts (Cornwall Insight, EnAppSys) expect the cap to stay broadly flat through 2026 with mild seasonal moves. A fix gives certainty; the cap gives flexibility. If a fix is 3%+ below the current cap with no exit fees, it's usually worth it.

Where can I get help if I'm struggling? Citizens Advice, your supplier's hardship fund, the Household Support Fund through your council, and the Warm Home Discount. We cover all of these in our fuel poverty guide.
