Superb customer feedback.

I called on Monday morning and spoke to Shannan who was brilliant. She was professional and extremely helpful, arranging to empty the tank that day and for an engineer the following day.

… I can only be totally complimentary for the service we have received from the first out of hours call to the successful conclusion. I have total faith in R A Dalton and would recommend them to anyone wanting a supplier or service provider for their treatment plant needs.

David Raw

Thank you to all you for all your help and advice and installing our new sewage system.

Martin and Chris have done a really great job. They have worked with good humour all week and did their utmost to cause us as little disruption as possible, considering the mammoth task they had to complete. Every thing was left tidy and looking good, you can hardly tell it all happened.

Graham Gamble

I was greatly impressed by all who worked on the project.

Ian Murray, contracts manager, was extremely helpful and thorough discussing the contract.

The team who worked on the installation were diligent, friendly and co-operative. At the time of the installation the weather was appalling but they continued to work hard and completed ahead of schedule, and when completed they left a very tidy site.

Mr Parsons

We have had excellent service throughout our contract with R A Dalton – from the initial advice and site survey (Ian) to the installation team.

The installation team in particular were fantastic, tidy, helpful, efficient and always keen to take care of my plants, and advise, especially as access is awkward.

And the office team are great too. Thanks everyone!

Mick and Ada
Just a quick note to say “thank you” to Carl, who carried out the service to our pump. He arrived early (which was certainly appreciated) and acted in a very professional manner throughout – proving an excellent representative of RA Dalton Ltd.
Brett Warburton

They provide both maintenance and installation solutions and carry out the work with utmost professionalism and efficiency, especially where they interact with our customers. I would have no hesitation in recommending them.
Colin Robson, Estate Maintenance Manager, Partnership Hotels
