Who can work on my existing lined chimney for my stove fit?
Updated: Aug 12
Besides questions on chimney sweeping in Cardiff etc. I have been getting a lot of calls from people who have work done on their chimneys lately and want to know if what has been done is correct. I saw a truly shocking picture over the weekend, a chimney stack had been demolished and roofed over by a roofing contractor. In one of the chimneys was an existing stove fit with a flexible liner so of course that had to be dealt with as part of the work. The contractor had replaced the section above the roof with a ridged system that was in fact only suitable for a gas appliance and would be highly dangerous to use with a stove and could well lead to a fire in the roof! Now the roof will have to be opened up and the position of combustibles adjusted in the roof and sections of twin wall insulated chimney fitted with the correct load bearing bracket.
If you want to alter the chimney in such a significant way then you must contact a HETAS engineer who can ensure the work is done correctly and sign off the work against building regulations. You can find a HETAS engineer at https://www.hetas.co.uk/find-installer/ and of course you need to check they have the right skill set for the job you want doing. On the page is some tips about checking ID and it has a link to some advice leaflets, (https://www.hetas.co.uk/consumer/hetas-advice/ ). For the leaflets you can click also click on the image of a leaflet.
From my point of view I would never quote if you ask me for advice in such cases as it just feels wrong, at least then you know I have your best interests at heart and in the case I have described I would advise you go to the person who fitted the stove in the first place and perhaps consider changing the liner at the same time for a whole host of reasons. When I am sweeping a chimney in your house it is just plain wrong to quote for work like this.
