  • I would highly recommend ph Water as I have found them to be a reliable organisation who work with their clients to provide the best possible service. This is why I had no hesitation in introducing ph Water to the London Borough of Redbridge who had been having problems with previous service providers.

  • HW are still the only WT specialist that have produced Zero Bacteria and Chemical results for Skanska to date. They are by a large margin my preferred specialist from a professional point of view, with the best engineers from the process world and the best technical backup in the country.

  • Full of praise for the professional way that your operatives conducted themselves. I also congratulate ph on the standard of the report very professional.

  • Their staff are punctual, well presented, knowledgeable and have good communications between site staff and office. Management/Sales staff give all required back up on technical matters Yes, I would recommend ph Water Technologies for future works. Using ph Water & Air gives me the comfort of knowing that the job will be completed correctly and affordably so giving me more time to run my own business.

  • I know we are inundated with approved Contractors but I would like to introduce PH Water – they are specialists in water treatment (amongst many other environmental solutions). The introduction is the least I can do for them, we have an ongoing Legionella issue at a building in Cambridge and their Directors Graeme Stevens knowledge, input and support in terms of findings a solution has been nothing short of brilliant. Based on my experience here, they are exactly what we need to support us in terms of compliance and maintenance at our buildings.

  • I’d like to just say a few words and thank you and your team for the service you provided at Langley Grammar school. We appreciated the professional service throughout the duration of the project and we had a successful outcome covering both the Water treatment, Air requirements and including aftersales communication/service which resulted in the handover and a happy client. I look forward to working with you on future projects.

    Project manager Wates Construction

  • I am happy with the professional manner that the project has been undertaken by PH Waters and Technologies, your engineers have shown great knowledge of the air and water systems and have commissioned the systems to design. The project has a high specification for achieving a pressure cascade through the rooms served by each AHU, this specific item has been achieved by your commissioning engineers with no difficulty. I would also like to add that both yourself and the engineers are good to work with and we also get a helpful response to accommodate the projects needs.

    Contracts manager Edge DBS

  • Just a note to pass on our appreciation and recognition of Ricky and Richard, they are both so attentive and efficient and out of all of our contractors the service and support is second to none, I know that everyone is always keen to moan and groan but I can honestly say I hear very little in relation to PHW even Wales and that is down to the hard work of both; it really feels like a partnership and one I am thankful for. I am sure you recognise this in them both but it is certainly noticed across our business.

    Group procurement manager Nationwide Leisure Provider

  • We had experienced recent issues with one of our ventilation AHUs distributing black dust and debris into our clinical engineering and kitchen departments. After identifying the root cause, the debris had already become confined within the ductwork. We then employed ph Water to undertake ventilation duct cleaning of this system, upon recommendation of using this company’s services at my previous Trust. Between May until now, ph Water have completed the works to a high and professional standard. Correspondence and arrangements were made for out of hours working, cost breakdowns were included within the quotations received, RAMS were acceptable and the reports clearly identified the findings, PVT analysis, photo evidence and pass/fail comments for the contamination levels that were taken.
