Buy your flexible chimney liner with peace of mind
You can install a stainless steel chimney liner easily and economically to repair an unsafe, deteriorated, or inefficient chimney. You can usually install a chimney liner without professional experience - just read our instructions (see fitting a flexible liner) and you can complete the entire job with regular DIY tools.
You should install a flexible flue liner to reduce the chance of a carbon monoxide leak, chimney fire, and creosote build-up. A chimney liner also improves the energy efficiency of your stove or burner and makes fireplace maintenance easier.
If you have a question in your head right now on which flexible lining system is best for your situation and the materials you may need, just contact us here.
Single wall pipes
You can choose single-wall pipes in two styles. We offer a black enamel flue pipe in a standard matt finish for visible piping or a stainless steel flue pipe for use inside an existing chimney that people generally don’t see. Whether you decide on our black enamel or stainless steel flue pipes, they fit easily together and are interchangeable without any fuss.
Stove "Connector" Pipes
Our stove pipe is a matt black, single-wall stove pipe. Its enamelled interior and exterior means it has a finish that lasts- as well as increasing its performance at high temperatures and being unaffected by condensation. At 1mm thick, you can easily cut these steel pipes using a grinder or a suitable saw from a DIY shop.
The single wall flue pipe is the standard used in homes all across the UK in order to provide a stable and safe outflow of air from heating stoves and burners. You use a black stovepipe to bridge the gap from the stove itself inside your home to the flue pipe system that takes the outflow into a chimney liner or chimney system. This is commonly called a "connector pipe".
All our stove pipes or “connector” pipes are UK approved for use as a stove connection to a chimney or liner, for domestic and commercial heating appliances. See our guarantee page for more details.
Twin wall flues for new chimneys
A twin wall flue system allows your stove to be installed practically anywhere in your home. Whether it's in an existing property or a new place you will be moving into, an isolated twin wall flue pipe lets you install a new chimney that is safe, effective, and easy to fit.
If you want to install a new heating appliance, such as a wood-burning stove, gas coal-effect fire, or an oil boiler, you will more than likely need an insulated flue system. If you do not have a brick chimney stack then you definitely need a twin wall flue system. These are really your only solution for creating a truly safe and reliable chimney system for your stove or burner.
Twin wall flue pipes are suitable for the creation of both indoor and outdoor flues and they can be used to pass through roofs and floors. Our double-wall flues are suitable for use with wood, coal, gas, and oil appliances.
Our Twin wall flue system is also perfect for biomass boiler installations. For twin wall pipes, top-quality ceramic wool is chosen as insulation material.
To fit a twin wall flue successfully and safely, you need the correct locking bands. All our twin wall flue systems and pipes come with free locking bands for ease of installation and your peace of mind.

Frequently asked questions
-
What is the difference between a chimney and a flue?
A flue is the channel, pipe, or tube through which gases and smoke travel from the fireplace to the outside. A chimney is, on the other hand, in its simplest definition, the housing that encases the flue.
There’s a misconception that masonry chimneys are simply made of brick. This isn’t true. The uneven and porous surface of brick provides a space for combustion byproducts to accumulate. This is a major fire hazard. Therefore chimneys are lined with a flue, so the smoke passes over a smooth surface that helps prevent excessive accumulation of combustion byproducts and minimizes the chance of fire. Read our full article on chimneys and flues here. -
What does open flue mean?
An open flue typically consists of a pipe to carry combustion gases from the fireplace, whilst fresh air enters the fireplace via the casing. So for safe operation, additional air vents are required in the room where the appliance is installed to re-supply fresh air.
-
Does a chimney need a liner?
If you are installing a chimney in a new build property and you want to use it for an open fire, wood-burning stove or gas fire, then the chimney does need to be lined to comply with document J of current building regulations. In an older property, your chimney doesn’t have to be lined to meet building regulations. An inspection by a chimney professional will tell you if you need to have it lined for safety purposes.
-
How does a chimney work?
Chimneys operate on the principle that hot air rises above cold air. Hot exhaust gases and ash are lighter in weight than cold outdoor air. The flue directs exhaust from these lighter gases from a fireplace upward to vent outdoors into the atmosphere. Additional air vents are required in the room where the appliance is installed to re-supply fresh air.
