• Lower energy bills due to improved efficiency.
• Reduced repair costs compared to older models.
• Lower environmental impact.

The best boiler depends on your home size and needs:

• Regular boiler – ideal for larger homes with higher hot water demand.
• Combi boiler – compact and energy-efficient for smaller properties.
• System boiler – designed for homes with more than one bathroom.

Boiler size is determined by:

• Number of radiators.
• Hot water usage.
• Home insulation quality.
• Fuel type.

Consider:

• Boiler type (combi, regular, or system)
• Hot water and heating demand
• Available space
• Energy efficiency rating

• Instant hot water.
• Compact design.
• Cost-effective installation.
• Ideal for homes with limited space.

The cost to replace your boiler is impacted by a few important things.

• The boiler’s brand and model
• Its physical size and energy output
• The location(s) of your old boiler and where you want your new one

A well-maintained boiler typically lasts between 10-15 years.

Through the Government’s Boiler Upgrade Scheme, you could be eligible for a grant to partly cover the cost of replacing fossil fuel heating systems with a heat pump or biomass boiler. Make sure you’ve checked if you’re eligible.

A boiler’s efficiency determines how much energy is converted into usable heat. Higher efficiency means lower energy waste and cost savings.

Replacing an old G-rated boiler with an A-rated one can save around £310 per year (Energy Saving Trust, April 2024).

* This estimated figure is from the Energy Saving Trust website and is based on fuel prices as of April 2024. The figure is based on replacing an old G-Rated boiler and installing a new A-rated condensing boiler with thermostatic radiator controls (TRVs), as well as a new programmer and room thermostat. This applies to gas heated semi-detached homes in England, Scotland and Wales, but savings will vary depending on the size and thermal performance of your home.

Boilers have one of two ratings:

• ErP rating (post-2015): A-G scale, with A+++ being the most efficient.
• SEDBUK rating (pre-2015): Percentage-based efficiency scale.

A-rated boilers (90% efficiency or higher) provide the best value.

• Lower energy bills due to improved efficiency.
• Reduced repair costs compared to older models.
• Lower environmental impact.
