Useful answers
Drainage Specialist hiring FAQs
Straightforward answers to common questions about hiring a drainage specialist.
Do I need permission to repair a drain?
It depends on who owns the drain or sewer and what work is proposed. Work affecting public sewers or new connections can involve the sewerage company and, in some cases, building-control requirements.
Should I get a CCTV survey?
Not every blockage needs one, but CCTV evidence can be valuable where damage, repeated problems, excavation or lining is being proposed.
