What customers say

Based on genuine customer reviews

Septic Tanks North West is described by customers as a specialist in replacing failed septic tanks and soakaways with new treatment plants, most often Graf sewage treatment works and treatment units. Andrew is named repeatedly for assessing sites quickly, producing reports and quotations, and advising on the most suitable system and on government regulations. The installation teams, including Ben, Michael, Ash, Lawrence and Lee, are praised for working through difficult wet weather and heavy clay ground, completing jobs when promised and leaving gardens and ground tidier than they found them.

Several reviewers describe thorough explanations during the work and clear communication from first enquiry to completion. A point that comes up often is the fair, competitive pricing and the way projects were delivered with minimal disruption, even when a property sale depended on a new tank being fitted at short notice. Customers also mention tidy, professional and conscientious working, from the office staff to everyone on site. The recurring picture is of a knowledgeable team that handles septic tank and treatment plant installations, including work in sensitive locations, with care for the finished result.

It isn’t often that a firm delivers what it promises, when it promises, and at a very fair price, too. From the boss to every team member on site, and the office inbetween, everyone was a delight to deal with. We couldn’t be more pleased with our new GRAF sewage treatment plant.

We have also just had a Graf Water Treatment system fitted by Septic Tanks North West and I could not recommend them highly enough. Specifically, Lawrence and Lee did a superb job not only with the extensive groundworks involved but also with installation of the new system and, just as importantly from our perspective, leaving the farm yard, garden and grounds in a state almost as if they hadn't been here ! Lawrence is an absolute master on a Kubota digger by the way too !

I would recommend Septic Tanks Northwest to anyone. They really helped me get the sale of my property through by installing a new water treatment plant at short notice with minimal fuss. Thank you Andrew.

We recently had a Graf One 2 Clean water treatment plant installed by Septic Tanks North West and from start to finish they were amazing! Andrew was so helpful and kept in touch with timescales etc. Lawrence and Lee installed the tank, they were so professional and conscientious, conditions weren’t easy as the ground was so wet and we are on heavy clay soil. They tidied the ground up so well when they finished you would hardly have known they had been there. To say we were delighted with their work is an understatement, if you need a new septic tank don’t hesitate to choose Andrew and his team, you won’t be disappointed!

"Andrew arranged to visit the site quickly to assess the job and provide a quotation. We are extremely impressed with the outcome. The team were extremely professional, neat and tidy in their work and completed the job on time as promised. I am very happy with the way the whole project was delivered with minimal disruption and have no hesitation whatsoever in recommending them. Brilliant company to do business with."
