A flue liner is a metal tube installed inside a chimney that improves safety, performance, and compliance with UK Building Regulations.

Key Benefits

1. Improved Safety – Helps prevent chimney fires by containing sparks, embers, and hot gases.

2. Better Efficiency – Maintains higher flue temperatures, improving stove draw and combustion.

3. Lower Fuel Costs – More efficient burning means less fuel is needed to produce the same heat.

4. Reduced Carbon Monoxide Risk – Helps ensure combustion gases are safely expelled from the home.

5. Longer Chimney Life – Protects the chimney structure from heat, moisture, and corrosive gases.

6. Added Value for Property Sales – A properly lined and certified chimney can provide reassurance to future buyers.
