Amazing service

Luke and his team were the most efficient, hard-working and genial chaps that we've ever encountered! Despite extremely hot weather and heavy work, even when they had to deal with our rising water table turning the tank over, they kept at it with great humour! They left the site better than when they found it and liaised with us at all stages. I could not recommend the company any higher, everyone we dealt with was professional and cheerful.

Excellent company for drainage services

Proseptic replaced an old cesspit with a new sewage system in July, and made it a very easy process for us. The company worked seamlessly to deliver the solution: from Tom with the site survey & design, to Sarah & the operations team who managed deliveries / collections and kept us updated, to Luke and the team on the ground doing the actual installation and commissioning of the new system. The site was left in great condition, just needing time for grass seed to grow. The fixed quote generated from site survey was the final charge - no hidden surprises.
Overall the streamlined installation process really showed the benefit of Proseptic's expertise and experience in these types of specialised relatively one off drainage solutions.

Good job well done

Everyone from reception to accounts to the guys doing the work were polite and helpful. The work was completed a little late but that was because of late deliveries from other companies. We were kept up to date with everything. The garden was protected so minimal damage and all was made good. Very happy with Proseptic.

We recently had a sewage treatment plant installed in Guildford and couldn’t be more pleased with the service we received. The entire team were professional, hardworking, and a pleasure to deal with from start to finish.

We were kept well informed throughout the process, and everything ran smoothly and on schedule. The quality of the installation was excellent, and the site was left tidy and well-finished.

A huge thank you to the whole team for their efforts — we thoroughly recommend their services and wouldn’t hesitate to use them again.

I am extremely pleased with the service provided by Proseptic. From start to finish, the team demonstrated the highest level of professionalism and efficiency. The work was completed in a timely manner, with excellent communication throughout the process.

The team on site was courteous, knowledgeable, and clearly experienced. They worked with great care and attention to detail, leaving the area so clean and tidy that you could hardly tell any work had taken place.

It was a pleasure working with such a reliable and professional company. I would not hesitate to recommend Proseptic to others and will certainly consider them for any future needs.

Continuing good service

We had a STP installed 4 years ago by Proseptic with no problems. Since then it has been serviced annually and we are very satisfied with this arrangement and especially with Ollie who is an expert engineer, always friendly and ready with advice based on years of experience. A good company overall.

Treatment plant installation

Proseptic have just completed the installation of a new treatment plant for us.

The work was done promptly and neatly; the installation team (Nick and Darren) did a great job in difficult circumstances, and the administrative side has been handled very efficiently.

Totally Competent and Reliable

Selecting a reliable Company from those advertised, can be a minefield.
Careful reading and cross checking was done for several potentials, and Prosepitic were chosen on a basis of cost and professionalism.
After a site visit, the type of drainage field was determined.
Two very competent men did the work over a five day period, and were considerate and friendly.

I am very happy to recommend Proseptic

I am very happy to recommend Proseptic.
We have recently had a new sewage treatment plant installed.
The service we received was first rate, from the initial survey through to installation and completion of the job.
I was particularly impressed with the site team who were polite, hardworking and went the extra mile. I would like to give special mention to Stewart. Nathan, Luke and Aiden for delivering a fantastic project.

Thank you!

Proseptic have been fantastic in helping us through a stressful job. Tom explained all our options and gave comprehensive quotes. Works had to be paused halfway through for water board and neighbour discussions, which proseptic helped us navigate. We had two teams on site for the two parts of the job; both were very tidy, efficient and knowledgeable. Would happily use them again
