Whilst attending a neighbours property, James from Allerton kindly offered some really helpful advice and guidance on my own sewerage system. I will definitely be contacting them for maintenance services in the future.

Excellent service. Engineers arrived punctually and despite awful weather and working conditions set about resolving an outlet issue with my treatment plant. I was kept informed of developments throughout the whole process in a clear and concise manner. I was impressed by the way both engineers systematically approached their work which gave me confidence and alleviated my concerns.Finally after resolving the issue in the late afternoon, and with another call to make, the engineers only left my property when they were satisfied that the system was working as it should. Great customer care - very much appreciated.

Brilliant company!
Engineer came straight to site, assessed, explained and came up with a solution to repair the unit. His office contacted me that same day and booked in for the repair, explaining everything I needed to do.
Repair was carried out super fast and on time by a great bunch of blokes. They showed me the job after finished to check I was happy.
I gotta say, I couldnt be happier!
THANK YOU ALLERTONS!!!

I always receive an excellent service from Allertons. All staff seem to have a refreshingly genuine 'can do' attitude and the work they undertake is always value for money. Thank you all.

Excellent company! Always helpful when called and have reasonable charges. The young man who came was well on time. He was efficient, friendly and informative about the work he carried out. I feel confident using Allerton's and I would recommend them.

Jason and Aaron came to unblock my drains today, they were very courteous and polite. They went about the work in a very professional manner, and it was easy to see, they knew exactly what they were doing. I hope I never have another problem like today, but if I did, you'd be the first people I'd call. Can't thank you enough.

We moved into our new home complete with Allerton Sewage Treatment Unit in 1994 and some thirty years later I can say that the unit has worked wonderfully well with only regular maintenance and two replacement electric pumps paid for - no wastewater charges from Anglian Water. Jon Allerton and his customer first team have always been great to deal with at the biennial maintenance visit. The too many to count froglets that appeared in the unit some years ago were merely a bonus!

Used Allerton's for nine years. Apart from annual service of the pump also had a new pump and guide rails.
Always turn up and provide what we consider to be excellent service. Previous owners never had pump serviced and the installer didn't want to know when asked about servicing. Luck to have found Allerton's

Excellent service from Allertons when my Consep failed to pump out. Called them just before closing on the Thursday, their engineer was with me by 8am the next day. The problem was quickly resolved and I was given advice on what to do if the problem re-occurred.

I would like to say a huge thank you to Allerton Bradley. I had a survey done on my septic tank by them this week. Having been really stressed about my house move, I booked the survey.
Allerton Bradley were recommended by one of my neighbours. The appointment was confirmed and took place within a couple of days of me emailing my request.
James, the engineer came out and was incredibly courteous and professional. Also knowledgeable, most informative and reassuring.
There was a comprehensive report which I received within 2 days of the survey.
I thoroughly recommend this company and have indeed recommended them already to all my neighbours and friends who have septic tanks.
Thank you to all at Allerton.

Sewage Treatment Plants are a very important part of the home and we wouldn’t trust ours to anybody else other than Allerton. They installed the system many years ago and have maintained it ever since. They are professional, knowledgeable and always courteous. They always go out of their way to help, going the extra mile every time. I can’t recommend Allerton highly enough. In fact on our recommendation, our next door neighbours have installed an Allerton system too and are as happy with it and the service they’ve received as we have been.

Allerton Bradley installed a treatment plant into our existing septic tank in 2020. Until then it had proved very problematic. Since then we have never had any problem with it, and in a couple of the years since have not had to have it emptied either. They are always friendly and approachable and very responsive. Very happy to have chosen them.

Allerton's work installing a new domestic sewage treatment plant was first rate. From the initial visit and quote through to the installation everything was prompt, efficient, friendly and lived up to all promises and expectations. The installation team were great to work with, and despite some interesting old drainage issues when excavating the new location and decommissioning the old septic tank, they maintained their good humour and professionalism throughout. I can highly recommend their services. Thank you.

Excellent system and the engineer (Dayton) who carried out our annual service recently is clearly very skilled, taking the time to explain things to us and ensuring the septic tank was working correctly, he also enjoys his job which is refreshing to see. The tank still doesn't need emptying after 3 years, very satisfied!

Many thanks to Allerton Bradley and especially Jason, Chris, James, Aaron and the team for a top rate service from start to finish. Had a new Diamond DMS3 water treatment plant installed to replace our old septic tank. Extremely professional installation, great communication throughout from the guys on site and the office, tidy, punctual and a fantastic end result. I would say I'm not the easiest to work for, have very high standards, know exactly the job i want done, do not employ many companies as prefer to carry out most jobs myself, however it was a pleasure having these guys on site. Would not hesitate to recommend. Oh and its great to be able to use the loo's etc whenever needed rather than going to the local garden center to use their facilities!!! Many Thanks, Graham & Catherine

We have used Allerton to maintain our household pump system for several years. Always found their staff pleasant and helpful. Last weekend a fault developed which we reported on the Monday morning. By Monday afternoon they had called, identified the fault, offered advice, made the repair and everything left tidy and all with a smile.

Living close to one of Hampshire's best chalk stream rivers, having the right treatment plant that is compliant and meets with the EA's stringent regulations is a necessity. Our old cesspit did not meet with the latest regulations so when we looked into changing to a sewage treatment plant Allerton gave us the reassurance and expert knowledge that we needed. The treatment plant has been installed for over a year now and we have just had our annual service. The team at Allerton are all knowledgeable, professional, helpful and courteous when ever I have needed to contact them, nothing is too much trouble. I would recommend the company and specially if you live close to a river where specialist advice is needed when considering the options of changing from a septic tank arrangement to a compliant treatment plant.

Two members of the Allerton team decommissioned my old Allerton 6PE pumped outlet sewage treatment plant this June in West Sussex. What came across was a determination by them to meet the highest professional standards whilst at the same time displaying every common courtesy combined with good humour. They worked tirelessly in temperatures approaching 27C and humidity for 1.5 days, and in addition speedily resolved problems regarding additional materials required. My cottage property was left as they found it, and all waste materials and refuse were removed by them.
You would have to search hard to find better - a sincere thank you Tom, and Jason, and for his administrative support, Aaron. I wish the Allerton business well - it deserves it!
