Superb company, very responsive to my calls and excellent pricing. Thank you to James, Steve and Miles and to the wonderful office staff too, please use this company-you will not be disappointed! James Cook
Good STP systems and great maintenance support and annual servicing from a highly qualified and customer centric team of excellent engineers. Big shout out to Zak Harrison for his excellent recent service visit, which was professional and efficient and also friendly and helpful
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.
As a customer for almost 20 years I am pleased to recommend Allertons for their efficient professional service; their work technicians have always proved helpful as was Zak who is the most recent.
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.

Efficient, pleasant and polite, service completed and area left clean and tidy
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.
Excellent company to deal with. Knowledgeable and great people. James who did the survey and Aaron who organised it.
Very pleased that I chose them. Higfhly recommended.

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!
Excellent service, great communication and lovely people to deal with.
I first wrote this review 3 years ago and they have consistently delivered excellent service since then. Very friendly and professional

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
Cannot recommend Allertons enough! Excellent service with speedy attendance by an engineer and the problem of a faulty timer was resolved without being too costly! Will definitely be saving their contact number on speed dial!
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.
Great service, good to receive email reminder when service is due!
Very pleasant person arrived promptly to do the service.

Fantastic service from Allerton. Chris was brilliant! He was punctual, polite and professional. The finish was outstanding. We are so pleased with the result. Would definitely recommend Allerton and Chris. Thank you so much.
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.
Alerton is a reliable company that thrives on clear customer contact, providing us with a no nonsense practical service that is invaluable and most necessary.
Allerton personnel are pleasant, informed and helpful. We have used the company for years and intend to stay with them.
Thank you Allerton for your immaculate service.
