yep, i have the same nightmare each year. i managed to put them off for 3 mnths last year but it was a pain in the ass. and in the end they applied to get a court order to enter my property. so i just have to do one less grow a year. luckily its during the summer, so not too bad, but still could do with out it.
i'm not sure having your gas capped will stop them coming mate, because if you have a boiler they have to by law, service it once a year. good luck with it.
