Has anyone fitted a liner after not using one?

Skulls

I have been using logburners for years without a liner. I'm quite happy with the draw etc but, I have scaffolding ready erected on my roof for next door and gives me access to my chimney top, just thinking is it worth fitting a liner now whilst the cost would be very low, about £300.

Has anyone retro fitted a liner and has there been a big difference to the fire and the amount of wood you use?

Thanks in advance for anyone taking their time to respond.

I have had a Dovre multi fuel stove for 25 years now in a 'normal' flue.
I am having a Clearview multi fuel stove fitting in a couple of weeks from now.
Clearview recommend having a lined flue so I am having a liner put in.
Thing is my chimney is just over 100 years old so I thought I would have it lined as recommended by Clearview.
I suppose I might be able to answer your questions about the fire & wood consumption in 2 or 3 weeks time !!
Thing is if the scaffolding is up there it might be sensible to have the job done.
A liner can't make things any worse can it ???

It depends a lot on what the existing flue is and make/quality of the appliance, all the quoted stove effencies are based on their ideal flue size wether its be 5/6/7 inch etc.
Having a stove exit into a square 9inch flue from a 5 inch diameter flue pipe can increase the draw and loose efficency, but it can also cause all sorts of problems with tar forming as the size of flue can cool the gas allowing them to reach the dew point and tar/creosote forms this can cause fires blockages etc.
Aliner will make the stove run better and may increase the heat output depending on appliance, they do need to be looked after or they can fail in 3-5 years use good dry wood avoid slumbering and have a good hot fire every day and it should last for years, seen sme 20+ years old and still OK.If you go ahead make sure the flue is swept well before hand rotary or power sweeping will make sure its as clean as possible, any tar left in the flue can attack the new liner from the outside and could catch alight, always insulate well if external wall and not damp chimney/flue
Remember all work on solid fuel needs to be signed off under building control or by a HETAS engineer.

My current chimney is 3ft deep and 6ft wide for the first 15ft then narrows down to about 12" x 12", it's an old inglenook fireplace. 200 years old this August and once owned by Lloyd George.

Fitting a liner is a must imo
But the figure of £300 seems a liťtle low?
You need to get a HETAS engineer to fit these and
