About the company

Cotswold Drainage Ltd is an independent, family-run drainage specialist company based in the West Midlands. The company is insured and serves Worcestershire, Warwickshire, and Gloucestershire. It provides drainage and off-mains services, including a 24/7 emergency call-out service and on-site service within 24 hours.

What customers say

Based on genuine customer reviews

Households replacing an old septic tank with a sewerage treatment plant, along with farms and businesses needing CCTV surveys or tank cleaning, form the sort of projects Cotswold Drainage Ltd takes on. Several customers describe the firm as organised and punctual, with work starting when promised and quotes honoured even after a long gap between enquiry and re-engagement. Communication is a recurring theme: clients mention being talked through each stage, kept informed of progress, and given honest advice about whether extra work and costs were needed.

Named staff appear often in feedback, with Callum and Arran praised for working hard in extreme heat and difficult ground water, Shaun and Mark credited with valuable expertise, Oscar described as brilliant, Adrian as knowledgeable and professional, and Ellie handling bookings efficiently. Reviewers frequently point to tidiness and the friendliness of the operatives on site, and the technical scope ranges from unblocking and CCTV drainage surveys to septic tank emptying and treatment plant servicing. Problems such as delays and challenging conditions are described as handled openly rather than left unresolved, and the office team is singled out for efficiency. Repeat custom for annual servicing and cleaning is a point that comes up often.

I was pleased to find that although this was not a straight forward visit, I was helped and assisted until we had ascertained what needed to be accomplished. A great guy, friendly, knowledgeable and dedicated. The report showed exactly what was required. Fantastic company I will use if needed without hesitation. Well done

Excellent service from initial contact to job completion. Callum and Arran worked their socks off in 30C and in spite of some ground water challenges the installation went well. Shaun and Mark provided valuable advice and expertise and we had great communication from the Office staff. I can thoroughly recommend Cotswold Drainage for any drainage works.

Pre-work was very professional. Initial site visit was thorough and the estimate quickly delivered. I had previously contacted the supplier who had recommended Cotswold, so I was made fully aware of what would be provided. The work began on schedule and was carried out expeditiously by a very friendly, hard-working team. Kept informed of progress throughout. Contacts friendly and efficient. Work completed 2 days after original schedule, but was not bothered due to standard and cleanliness of the whole operation. Costs were exactly on estimate. All in all a great job and would highly recommend Cotswold Drainage,

Cotswold Drainage Ltd were very organised, punctual and efficent with both the septic tank emptying and also the CCTV survey. I cannot fault them and both the guys who we dealt with on the day were such great advertisements for the company. A pleasure to deal with all round.
