Barry from BN Drainage was very polite and professional he went the extra mile to ensure that the job could be finished the same day and left the area clean and tidy . .The manhole that needed to be accessed to cap of the drain is on our neighbours driveway  and Barry was able to reassure them and me about the process . I would have no hesitation in recommending BN Drainage .

I would highly recommend BN Drainage. I called them out to fix a blocked drain, and they arrived within the hour. They quickly identified and fixed the problem, providing a fast, efficient and professional service.

They also sent over a job sheet detailing the work they had carried out, which was really helpful and kept me fully informed throughout.

Their prices were reasonable, and they were friendly and approachable from start to finish.

Overall, a great experience with a reliable company that I wouldn’t hesitate to use again. Highly recommended!

We'd had a blocked manhole and a toilet that wouldn't clear properly for about two weeks, so I was glad to get someone out. A contractor from BN Drainage attended, explained clearly what the problem was, and got stuck in straight away.

He was friendly, straightforward and didn't oversell anything. The engineer came out in the morning to finish the job. All sorted.

BN Drainage were incredibly helpful with our pre-purchase CCTV survey. Dan and Barry explained the findings clearly over several phone calls and kindly reviewed repairs carried out by another contractor following their survey. Great communication and support throughout a stressful house purchase. Highly recommend!

I’ve had a fantastic experience with Dan and the team at BN Drainage. From start to finish they were professional, knowledgeable, efficient and reliable.

The work was carried out quickly and accurately and their pricing was extremely competitive without compromising on the quality of the service. Dan clearly knows his trade and took the time to explain everything clearly, which gave me complete confidence in the work being carried out.

If you’re looking for a drainage company that combines knowledge, professionalism, efficiency and great value for money, I would highly recommend BN Drainage. I wouldn’t hesitate to use them again!

Thank you all for your help :)

Extremely happy with BN Drainage who surveyed our drains before the purchase of our house , came following purchase and repaired our drains and unblocked our sink.  Every interaction was easy, every appointment was confirmed the day before and they turned up on time and did a first class job. I highly recommend!!!!

This is a bona fide feed back review about BN Drainage Ltd, written with integrity and honesty. We recently discovered the horror of broken gulley drains and leaking water into our basements (i.e. our neighbour and ourselves because the gulley grains were connected) and were introduced to this drain specialist by our local Whatsapp group. From the beginning to the end of the job they have been an excellent company. Courteous and respectful (for us an important part of the relationship with any company); They inspected the drains and we received a detailed breakdown & invoice of the work that had to be done. The cost was very reasonable and much cheaper than we anticipated. It was a big job because our neighbour's drain being connected to ours, meant that they had to do the 2 jobs together. They set a date for the repairs and came on time as planned. We were expecting a big messy job with mud everywhere, but they were respectful of our house and living space and curtailed the mess and mud and cleared away the old drains and debris and left the site clean ready for us to do our home cleaning-up. They removed the old drains, pipes & debris etc from our house altogether. We anticipated that our conservatory tiles would have to be broken during the work (and replicas hard to find since they had been down for many ears), but the engineers found they did not have to do this and preserved our tiles. We received an excellent professionally produced report about their findings (before and after the job) and details of the work they had carried out. They really do deserve a big 'thank you' for a job well done, for a very good cost and deserve a 5 star rating.
