EXCELLENT Based on 30 reviews Rod Hamilton2025-08-18Trustindex verifies that the original source of the review is Google. OneFlow Drainage were extremely helpful in assisting with a domestic collapsed drain issue. The drain had previously been poorly repaired by another company and I contacted OneFlow to see if they could help. Malika at OneFlow advised that this was probably a shared waste drain and therefore the responsibility of the local water board. She told me to call them for advice as private companies could not touch the drain without permission. The water board did not have a record for my property so asked me to employ a company to produce a survey report. OneFlow were happy to conduct a CCTV survey and write a report which was delivered to the water board. This was all done in a very professional and timely manner and the water board have subsequently conducted a full repair of the drain and accepted responsibility for any future work. I'd recommend OneFlow for any domestic drain work. Communication is excellent, they respond quickly and efficiently, work is carried out to a high standard, staff are friendly and professional, and costs are reasonable and up front.
