Switch to Wood Pellets: Save Up to 28% on Heating Costs

Wood pellets remain the cheapest heating fuel available to UK homeowners in 2026, but most households haven't switched because the process feels complicated. It doesn't have to be.

Why Wood Pellets Make Financial Sense Right Now

At 7.2p/kWh, wood pellets are still cheaper than mains gas at 6.04p/kWh when you factor in efficiency rates. A modern pellet boiler operates at 85-90% efficiency, meaning you extract more usable heat per penny spent compared to older gas systems averaging 78-82% efficiency.

If you heat a 3-bedroom semi-detached house, the annual saving could exceed £300 compared to mains gas.

What You Need to Know Before Installing

Space requirements are the first hurdle. Pellet boilers need:

• A boiler unit (similar footprint to a traditional system)
• Storage space for pellets (a shed, garage, or dedicated room holding 5-10 tonnes)
• Easy delivery access for bulk orders
• Adequate ventilation for flue pipes

If you're in a flat or have no outdoor storage, wood pellets aren't viable—stick with comparing mains gas suppliers instead.

Installation Costs vs. Long-Term Savings

A new pellet boiler system costs £8,000–£12,000 installed, compared to £3,000–£5,000 for a gas equivalent. However:

• The additional £4,000–£7,000 upfront cost is recovered within 15-20 years through fuel savings
• Many homeowners qualify for boiler replacement grants or energy efficiency schemes—check your local authority
• Maintenance is lower: pellet systems need annual servicing versus biennial for gas

Your Action Steps

Step 1: Measure your available storage space in cubic metres. Pellets are sold by tonne; one tonne occupies approximately 1.3m³.

Step 2: Get quotes from three accredited OFTEC engineers who install pellet systems. Ask about warranty terms and servicing costs.

Step 3: Contact your energy supplier about removing your gas connection entirely. This frees up space and can reduce standing charges.

Step 4: Source reliable pellet suppliers within 50 miles of your postcode. Bulk orders (5+ tonnes) offer better rates and reduce delivery frequency.

Hybrid Heating: The Middle Ground

If you're uncertain, consider keeping mains gas as backup while trialling pellets. This costs more upfront but reduces risk during the transition.

Compare All Your Options

Before committing, compare heating oil prices, mains gas rates, and electricity costs alongside pellet options. Your ideal fuel depends on existing infrastructure, available space, and budget tolerance.

Wood pellets offer the lowest per-unit fuel cost in 2026, but installation barriers mean they're not right for every home. Run the numbers for your specific property before deciding.
