We've been using Cotswold Drainage for a few years. They are great to deal with and have always sorted issues out promptly with our septic tank. Shout out to Dave Streeter for looking after us so well!
- Nigel Carter
Great service - really hard ground and tough conditions and the guys came back the following Monday to complete the job at no extra charge. Thankyou
- Tim Stretton
Very pleased with service provided by Cotswold Drainage, Luke did a great job. Would certainly recommend them, very efficient. Arrived on site when promised and solved the problem, can't ask for more than that.

I’d happily use Cotswold Drainage again - the engineer arrived and within a couple of minutes had not only identified the problem but cleared the blockage. He then went on to give everything a good hose down and then did a camera inspection to make sure there were no more issues further down the drain. Highly recommended.
