Gilson Environmental Services did an outstanding job replacing my old septic tank with a new treatment plant, tackling a tricky site with professionalism and a can-do attitude. From navigating tight access and handling planning approvals to coordinating with Calor Gas, they managed every challenge with ease and attention to detail.

They went above and beyond—taking on extra tasks without compromising quality, improving the garden layout, and ensuring everything was finished to a high standard. I’m delighted with the result and wouldn’t hesitate to recommend them.

We were well overdue having our old septic tank updated (20yrs), it was a daunting task for us but we engaged Lee Gilson of Gilson Environmental, which was a very good choice by us. Lee and Jason made easy work of the change over and took care of every logistical task and in 3 days we were on the fantastic new system/ treatment plant. They have great background knowledge and work ethic, nothing was a problem for them.

So all we now look forward to is not being backed up when it rains hard - especially when guests are here and having the peace of mind knowing that the system works and having Gilson Environmental on hand should there be a problem. I can’t recommend them highly enough and you won’t be disappointed.

Gilson Environmental Services completed the installation of our sewage treatment works and renewed house drainage. Excellent work completed. The team are neat, efficient, and  communicated  well with us. The work completed was to an exceptional standard.

We used Lee and his team again to install the pipe work for a new downstairs toilet. Great service and again work completed was neatly done. The team are highly efficient & we would highly recommend them.

I am happy to recommend Lee and the team from Gilson Environmental. As a small high spec developer ourselves, it is essential to us that we involve the best trades in the marketplace, Gilson Environmental have been part of our preferred contractor list for many years now. During this time I have come to trust Lee, his experience and the quality
