Q: What's the difference between gas and oil boilers?

A: Gas boilers use mains gas or LPG and are the most common type of boiler. Oil boilers run on heating oil, making them ideal for homes that are off the gas grid. Both types are available as combi, system or heat-only models, and deliver reliable heating and hot water..

Q: How does a boiler work?

A: A boiler heats water for central heating and, in some cases, domestic hot water.

• Combi boilers provide heating and hot water on demand, with no cylinder or tanks.

• System and heat-only boilers store hot water in a cylinder and are ideal for higher water demand.

• All boilers use a fuel source - natural gas, LPG or heating oil - and circulate hot water to radiators and taps as needed.

Q: How much does a new boiler cost?

A: Boiler costs vary by type, output and brand. As a general guide you should expect to pay anywhere between £1,000 to over £3000 for a new boiler. You’ll also need to pay for labour as boilers need to be fitted by professionals for safety and regulatory reasons. 

Q: How long does a boiler last?

A: With regular servicing, most boilers last 10 to 15 years. Oil boilers tend to have a slightly longer lifespan with proper maintenance. If your boiler is over 15 years old or needs frequent repairs, a replacement may be more efficient and cost-effective in the long run.

Q: Is it worth replacing an old boiler?

A: If your boiler is more than 15–20 years old, it's likely running at lower efficiency and may be costing you more in energy and repairs. Replacing it with a modern, energy-efficient gas or oil boiler can improve performance and reduce your heating bills.

Q: Do you stock boiler accessories and spares?

A: You’ll find a full range of accessories to support installation and maintenance, including:

• Boiler flue kits and extensions.

• Wall brackets and jigs.

• LPG conversion kits.

• Valves, pipe fittings and filling loops.

We also offer system protection products like filters, scale reducers, and water treatments.
