Hi all.
I've got my woodburner installed now (a 4kW model). The installer told me no external vent was required below 5kW.
A while back I had a survey/quote for CWI. At the time I had a normal fireplace, and they told me they were required to add an external vent in the wall in the front room. This added 50 quid to the price.
I want to resurrect that quote and get them back to do the job, and I was wondering if anyone knows the letter of the law regarding vents. Do the people doing the cavity insulation have to fit a vent if the woodburner is less than 5kW?
Thanks in advance.
