Hi thanks for the reply. Seen Kiln linings but probably won’t be near the £200 minimum limit which is frustrating.
Probably just have to sit it out despite have a couple of weeks spare time 😭[/pquote]
If you are not far off the £200 minimum I would consider just buying extra bricks. If you don't use them, they should eBay well. Mine did. Or offer them through this site. I remember my local builders merchant wanting a ridiculous amount per brick compared to kiln linings. Made no sense ordering local but have a ring round where you are. Maybe try fireplace shops. I got two cheap bags of vermiculite from a company that mend cooking AGA's!
