Andrew is the best plumber I've come across - knowledgeable, hard-working, thorough, professional, explains what's going on. I thought I had a blocked toilet, which turned out to be a blocked main drain, which for some reason South East Water didn't have on their official plans. Andrew unblocked the drain and sorted everything out with South East Water afterwards, so I didn't need to deal with them on the phone (or explain to South East Water the situation, which I wouldn't have been able to, given my very limited knowledge of the terminology). Very reasonable cost as well, and gives a 10% WOMO discount. Definitely would recommend him to anyone!
