Hi all many thanks for all your replies and sorry for radio silence - been a few developments this end - rat people have come and laid some bait which is killing them off but the smell isn't a rat smell at all which rules them out.
i was outside the other day where the boiler flume is and it smelt exactly like it did in the drains!! So... I switch the heating off and leave on hot water only... Voila the smell has gone.... So I think I may need to now move this over to the boiler forum to continue the investigation... I've been reading about the condensate trap being empty and allowing sulphur fumes out into the vent pipe.... It's got to be that! So relieved to be able to stop the smell though was driving us crazy! Thanks for everyone's help to date
