Client Testimonial
“Dean from Groundsource sat down with us and went through the whole scope of works so that we both understood how the works would progress and the timescales involved. The works comprised of replacing our old cesspit with a sewage treatment plant and associated drain cleaning. From day one the work was carried out in a very clean and efficient fashion, there were a couple of unforeseen issues that cropped up but these were dealt with very quickly and with no fuss. The project was completed to our satisfaction and I would have no hesitation in recommending Groundsource Drainage.”

After a terrible experience with a previous contractor that caused major delays and unexpected costs, GroundSource were an absolute lifesaver. They managed everything — from the groundworks and sewage connection to all the sign-offs and inspections — quickly, professionally, and with minimal involvement needed from us. Excellent communication throughout and a completely stress-free experience. From the workers on the ground to the management and operations team. Their expertise has been an invaluable guide throughout - Highly recommend! C Hill7 August 2025Trustindex verifies that the original source of the review is Google. One of the best firms I have ever used. Extremely efficient with knowledge, suggestions and doing the work. Great to have Dean and his team on site - hard working and friendly. They have given us complete peace of mind. Just one criticism. Some weeks on and no commissioning certificate, which will be important whenever we sell.
