Summer 2026: Why Now Is Peak Season to Upgrade Your Heating
With energy prices stable but high, June is your ideal window to install efficient heating and lock in savings before winter demand hits.
Summer months are when heating engineers have availability, installers offer competitive quotes, and you can complete upgrades before October. If your boiler is over 15 years old or you're burning heating oil at 90.1p/litre, now is the time to act.
The Current Price Picture
At today's Ofgem cap rates, mains gas costs 6.04p/kWh while electricity sits at 24.5p/kWh. These prices remain elevated compared to pre-2021 levels. Homeowners relying on heating oil face particularly sharp costs, making efficiency upgrades a genuine financial priority rather than optional.
Wood pellets remain competitive at 7.2p/kWh for those with suitable space and access to reliable supply.
Three Upgrades Worth Considering Now
1. Boiler Replacement
Modern condensing boilers achieve 90%+ efficiency compared to 70–80% in older models. A typical family could reduce gas consumption by 20–30%, translating to hundreds of pounds annually. Compare mains gas providers to find the best rates once you've upgraded.
2. Insulation and Draught-Proofing
You don't need a new boiler to see immediate savings. Loft insulation, cavity wall filling, and draught seals are cheaper, faster, and often eligible for grants. These cuts heat loss, reducing demand on whatever system you use—whether gas, oil, or electric.
3. Heat Pump Consideration
For those on mains gas, an air-source heat pump can seem expensive upfront, but combined with good insulation, they're increasingly cost-effective over 10+ years. Electricity costs at 24.5p/kWh are higher per unit, but heat pumps deliver 3–4 units of heat per unit of electricity consumed.
Why Summer, Specifically?
- Engineer availability: Winter waiting lists are long; June appointments are quick
- Competitive pricing: Installers offer discounts during quieter months
- Installation comfort: No rushing; work can be thorough without freezing weather complications
- Winter readiness: Upgrades complete before October, when heating demand and prices spike
Your Action This Week
Request three quotes for either a boiler replacement or insulation package. Include both gas and electric options if considering a heat pump. Compare the annual running costs—not just installation price.
If you use heating oil, compare current rates and ask installers about conversion to mains gas or air-source heat pumps during quotation calls. Oil-dependent homes benefit most from switching.
Bottom Line
Energy prices may stabilise, but they won't fall dramatically. Your best defence is reducing consumption, not waiting for price drops. Summer 2026 offers the perfect window: good weather, available tradespeople, and time before winter demand forces prices higher and books fuller.
Start today with three quotes. The savings begin in October.
