Buyer notes
Why Choose WTKnowles?
In 1906 Walter Thomas Knowles commenced the successful business of clay pipe and chimney pot manufacturing at its current Ashgrove Pipeworks site in Elland in the old West Riding of Yorkshire (now West Yorkshire) close to the industrial centres of Bradford, Halifax, Huddersfield and Leeds. The reason for the choice of this location was probably the local rich coal and clay seams and the proximity to the adjacent Calder & Hebble Navigation canal which links Wakefield with Manchester via a junction with the Rochdale Canal. A main arterial railway line passed less than a mile away and between them, the canal and the railway provided the company with excellent distribution routes for its products.
Walter’s sons joined the business in the 1920s and by the 1950s they were running the growing business. About this time, the third generation family joined the company and by the 1970s they had taken control. Now the company is run by the fourth generation family.
Shortly after World War II there were around about 80 individual chimney pot and clay pipe manufacturers; today there are only three clay chimney pot manufacturers in the UK. The massive project for re-building damaged and destroyed homes and after the war ensured W T Knowles had a major supply programme for its wide range of chimney pots over quite a long period.
OUR CHIMNEY POTS
W T Knowles is the only privately owned manufacturer of chimney pots in the UK.
Many of the traditional clay moulding processes from the early 20th Century are still retained, producing both glazed and unglazed products. The original kilns were all coal fired but today company has six down-draught beehive kilns five of which are gas fired with just one remaining coal fired kiln.
W T Knowles is the only UK manufacturer offering traditionally glazed chimney pots.
The clay chimney pots are designed and manufactured to BS EN 13502:2002. A very wide range of clay chimney pots have been tested and certified by BSI.
A quality system to BS EN ISO 9000 is in operation.
Choosing the Right Chimney Pot
Choosing the right chimney pot is essential, whether you’re replacing an old one or installing a new fire system. Either way, a chimney pot should be chosen for functionality and suitability for the service, ease of fitting, and aesthetic appearance.
Some Solid Fuel pots, such as the Altham, Knight, Champion, Edwardian, and Ryburn, offer a striking visual effect, complemented by the traditional Bishop and Windguard pots. For a more minimalist look, Roll Top pots remain a popular choice.
Over time, specific designs and styles have become associated with different regions and have adopted the name of the area as part of the description of the pot. Examples include the Halifax Windguard, Leeds Bishop, Southport, Kendal, and Carlisle Blowdown pots.
Clay Chimney Pots: A Traditional Choice for Heritage and Performance
Heritage organisations, such as the National Trust, English Heritage, and World Heritage, frequently specify clay chimney pots to blend in with historic structures. In one notable case, W T Knowles was engaged to produce special Square Panelled Pots for the Salt’s Mill World Heritage Site in Saltaire near Bradford, West Yorkshire.
For like-for-like replacements, the decision is more straightforward, although there may be an opportunity to improve the performance of a fire by selecting an alternative pot. The style of the base, round or square, may be an influencing factor. Most chimney pots from W T Knowles are available in plain terracotta, salt-glazed finish or in an attractive buff shade. Traditional salt-glazed chimney pots are only available from W T Knowles.
W T Knowles offers an extensive range of over 180 terracotta chimney pots, terminals, and accessories designed for solid fuels, gas, and multi-fuel systems. Even when a flue or chimney system is no longer in use, W T Knowles has a wide selection of flue vents and blanking accessories necessary to preserve the status of the redundant flue. The accessories provide protection for the chimney system from the ingress of rain and nesting birds, and when flue vents are fitted, allow air to circulate to prevent stagnant and damp conditions.

Which pot is suitbale for solid fuel?
Any open pot is suitable for solid fuel.
What does a multi fuel pot do?
This pot can be used for more than one type of fire. It can be used on a living flame or solid fuel.
Which insert can i put in a crowned pot to stop the rain coming down?
There is no suitable insert to go on top of a crowned pot.
Which pot is suitable for a redundant flue?
Flue vent, bonnet hood and mushroom hoods may only be used for redundant flues.
Should i seal my flue when the fire feature has been removed?
Fitting a flue vent will prevent the ingress of rain and birds and allow the flue to ‘breathe’. A flue may be totally sealed by the fitting of a blanked off pot
Why can't I use a bonnet hood on my coal fire?
This pot does not give enough free air space.
