As far as I know you have to use smokeless fuels - can be bought in several places, I get mine from the mini supermarket on Barry Road. Its a source of amusement when I see the expensive shops on LL selling overpriced logs....... As for folk to come and clean, I have used S. Pearce for the last few years (though it has been the other half who has been in to watch him work). Try him on 0208 699 3713 or 2028857 6511. always clean and tidy, no complaints.
