Client Testimonials

Edmund has done a fantastic job on installing our sewage treatment plant. We couldn’t be more pleased. He was always willing to explain everything before hand and as work progressed. He did the job in the timescale he gave us and dealt with everything that was needed along the way. Edmund and his son did not seem to be phased by anything. Very professional and courteous. The finished job left the driveway looking far better than it did before! Great job.

Edmund replaced our old septic tank with a new sewage treatment plant to comply with the change in regulations. The job presented several challenges, one being that the area available to put the new plant was small and the area to where the treated water could flow into was not straightforward. However, Edmund navigated his way around these issues professionally and successfully. His work was excellent and to a very high standard. Building Regulations were very happy with his work too. I would highly recommend Mainline Environmental Installations Ltd without hesitation.

Edmund made a fantastic job of installing a new small sewage treatment plant on our property after we had a nightmare with our old septic tank and drains. It was a very complex job that required some lateral thinking but Edmund came up with a great solution that met Building Control requirements. The standard of work is excellent and overall we are very satisfied. The price was as per initial quote despite several complications cropping up and Edmund worked through the biblical rain to get the job done. The area looks better now than before he started. Highly recommended.
