Experienced plumber South East London

[user1482874333]

Can anyone recommend an experienced plumber who covers SE London? The issue I have is challenging and very likely to need complex remedial work so I am looking someone with plenty of experience who can determine the best next steps (I have twice had generic plumbing firms come out and resolve it temporarily - but it is too significant for that to be a viable longer term approach and it needs sorting properly). Thank you in advance.

Should have added - the reason the two other firms used the 'sticking plaster' method is that they were only really suited to common / day-to-day plumbing issues so I think that was within the limit of their capabilities - hence request for someone highly experienced.
