Domestic customers

“Shaun came very highly recommended by a friend who had had ongoing problems with his septic systems, problems that were only solved when ESTS took over the job. ESTS have lived up to every expectation set. They did a fantastic job of the installation and making good afterwards. I continue to recommend them to people needing help with existing systems or needing new installations.  

Gillian Turner – Wokingham, Berkshire

“The whole process of deciding on the correct tank, and then its installation, was very straightforward. Shaun is extremely knowledgeable about the options available, patient with repeated questions and was able to give a good recommendation of which system he considered best for our requirements. The installation was very slick, didn't cause the disruption that I'd anticipated and the garden was left looking very neat, with everything back in its place. I would definitely recommend ESTS in the future.”

Annie Sandon – Marsworth, Buckinghamshire

"Many thanks for the work you have done and for providing information to the financial Ombudsman. I expected more devastation to the garden but the workers were very professional and things look as good as they could at this time of year. Thank you." 

Mrs Lynn Kenworthy

"We are delighted with the quality of work carried out. Shaun’s project management skills are second to none and he and his team are courteous and extremely hard working. We would happily recommend you to any future customers." 

Eric Hall – Truro

"A very straightforward installation of our second Klargester from ESTS. I wouldn't hesitate to recommend them to anyone wanting this product / service." 

Rob Reynolds – Radlett

"ESTS were extremely helpful in navigating through various drainage issues on the site. The pre-installation advice and help was really good. It has been a good experience dealing with ESTS."

Steve - Foulmere

"We are very pleased with the installation process and the operation of the system so far. You and your guys were very helpful, efficient and tidy, despite the horrid weather. Thank you for all your work and expertise during this challenging installation. You made a potentially very difficult project seem easy for us, we really appreciate your input."

S&T Ryan - Tonbridge, Kent

"Shaun, big thanks to you and your team getting this done in a timely and professional manner. I will have no hesitation recommending ESTS to others."

G Cunningham-Walker - Cookham, Maidenhead

Commercial customers

“ESTS have helped us with drainage solutions on a number of projects now and I have been consistently happy with their advice and workmanship.” 

Tony Lewis – Property Manager at W.H.Brakspear & Sons Ltd.

“We have worked with Shaun and ESTS now for about ten years. They have installed hundreds of our MATRIX Treatment Plants from the smallest 6pe unit right up to the largest 300pe. The feedback we get from our customers is one of extreme gratitude that we have put them in touch with such an expert installer who are professional, clean on site and to budget. We would not hesitate in recommending ESTS to any of our customers and look forward to the next ten years of working in partnership together.”

Steven Lamb – Director, C+L Fabrication Ltd.

ESTS has attended site as a specialist sewage consultant for some 6 years. The company has worked on difficult and tricky sites including collapsed tanks and very high water table areas. ESTS’s work and diagnosis has always been to a high standard and is always carried out on time and within a set cost. The feedback given from policy holders is that of a high regard.

Steve Cable - Office Manager, Ansa Utilities 

“I have worked with Shaun and ESTS for the past 7 years on a range of projects from small domestic to large commercial applications . I always call Shaun first, because I know Shaun has the technical knowledge, will size the plant correctly for the job in hand, is quick to problem solve with difficult sites and is very competitive. I also know that if I have a site request, I don’t need to go - I can just hand it over to Shaun and he will put the client’s mind at ease and guide them through how the plant works and what they need to do to maintain it. I would recommend Shaun on a personal level and as a most competent installer of wastewater products who is extremely professional and well known in our specialist field.”

Mark Bishop - Area Sales Manager, Balmoral Tanks Ltd.
