How to Cut Heating Costs This Winter: Compare Your Fuel Options Now
With oil at 102.5p/litre and gas at 6.04p/kWh, choosing the right fuel matters. Here's how to pick the cheapest option for your home.
Winter 2026 is shaping up to be expensive for UK homeowners. Energy prices remain volatile, and your heating fuel choice directly impacts your bills. Whether you're on mains gas, heating oil, electricity, or wood pellets, now is the time to understand your options and lock in savings.
Compare Your Current Fuel Costs
Let's start with the facts. Today's typical UK energy prices are:
- Mains gas: 6.04p/kWh (Ofgem cap)
- Electricity: 24.5p/kWh (Ofgem cap)
- Heating oil: 102.5p/litre (ex. VAT)
- Wood pellets: 7.2p/kWh
These prices vary by region and supplier, but they give you a baseline. Gas remains the cheapest per unit of heat, though availability depends on whether your property is connected to the mains network.
Step 1: Know Your Current Fuel Type
First, identify what you're using:
- Mains gas (most common in urban areas)
- Heating oil (rural properties without gas)
- Electric heating (immersion heaters or storage heaters)
- Wood/biomass (increasingly popular for cost savings)
If you're unsure, check your most recent heating bill or contact your supplier.
Step 2: Calculate Your Potential Savings
If you're on electricity at 24.5p/kWh, switching to mains gas at 6.04p/kWh could slash your heating costs by up to 75%. For heating oil users, the economics depend on current crude prices and geopolitical factors—recent G7 oil releases may create short-term price pressure, but long-term trends remain unpredictable.
Wood pellets at 7.2p/kWh offer competitive pricing for those with suitable heating systems, though installation costs are significant.
Step 3: Take Action This Week
1. Compare mains gas suppliers if you're currently on electricity or oil
2. Check heating oil prices if you're in a rural area and locked into oil—bulk buying now may lock in rates before winter demand peaks
3. Review electricity rates if you're on a fixed deal—confirm when it ends and what renewal rates look like
4. Explore wood pellets if you have space for storage and a compatible heating system
Key Takeaway
Don't assume your current fuel is your best option. Switching suppliers takes minutes online, and even small unit-rate reductions add up across a heating season. For oil users particularly, secure your winter supply within the next 4-6 weeks before peak demand drives prices higher.
Energy volatility is your new reality. Act now to protect your budget.
