Very pushy.
Very pushy.
Sent a letter which I was getting around to dealing with.
They cold called at the doorstep confusing my elderly parents, I was luckily there to tell the cold called to go away.
This company is acting like it is the 1980’s, we have signs plastered over all of our door saying ‘No Cold Callers’.
This company put my parents in danger, they are at high risk of falls and had just been settled with cups of tea and programmes to watch.
I will be reporting this company for cold calling, ringing the bell and knocking on the door ignoring signs.

Cold caller from Control Flow Technologies
A representative from Control Flow Technologies Group cold called my house yesterday. Neither myself or my wife were home, but they managed to talk their way past my 82 year old father in law before making their way around my home on the premiss that we are using too much water. With clearly no attempt to check if he was the homeowner, they then arranged to install some sort of flow restriction. They left no paperwork, contact details, or any evidence of the planned work. When I called UU they could also find no details of the visit. We recently had a new water meter installed (I think the whole street had the same judging by all the discarded parts left behind). Following this we suffered from greatly reduced water pressure. I called UU and the next day someone (white van, no uniform, so guessing a contractor) turned up and removed something from the new water meter installed- I’m guessing it was the same thing that they have now organised to re-fit without the homeowner’s consent. I’m pretty disgusted by what’s happened. UU said they’d received a number of complaints about Control Flow Technologies and are investigating.

Misleading sales tactics
Misleading sales tactics. We were informed that there appeared to be a water leak on our premises due to increased water usage, and that the company was working alongside United Utilities to help identify the issue.
After requesting further information, I received an email which turned out to be a general water audit offering advice on reducing water usage and saving money, rather than any formal notification regarding a suspected leak.
I felt this approach was misleading. The sales representative’s communication did not accurately reflect the purpose of the contact and was not an appropriate way to promote the company’s services. A more transparent and honest approach would have been appreciated.

Hi Andrea,
Thank you for taking the time to share your feedback. We're sorry to hear that your experience left you feeling misled.
We work in partnership with United Utilities to offer customers free water audits, which are designed to help identify opportunities to save water, reduce bills, and, where leaks are found, arrange for these to be repaired at no cost to the customer. As part of this service, higher-than-expected water usage may sometimes indicate a potential leak, which is why a water audit may be recommended.
We understand your concerns regarding how this was communicated and appreciate your comments. We aim to ensure that the purpose of our visits and services is explained clearly and transparently at all times.
We would welcome the opportunity to look into your experience further. Please contact our team directly with your details so that we can investigate the circumstances surrounding your interaction and address any concerns you may have: watersaving@controlflow.co.uk.
Great company and communication.

We did not receive prior notification from United Utilities when an employee from ControlFlow turned saying we were using more water than we should be - we are fairly typical - and hustled their way on to our property, claiming to be from the utility to do our free water audit. We felt put on the spot and under pressure, including being made to sign something - we aren’t sure what - that we now suspect includes having flow control devices that we don’t want or need. Very unhappy with what appears to be high pressure sales.

Hi John,
Thank you for your feedback. We’re sorry to hear that your experience left you feeling uncomfortable and under pressure.
Customers should always receive communication either from us or United Utilities before any visit takes place, so we are concerned to hear that this may not have happened in your case. We take comments like yours seriously and would like the opportunity to investigate what occurred.
A member of our team will be in touch directly to look into this further, understand the circumstances surrounding the visit, and work with you to resolve any concerns.

Coming to properties Unannounced!
I did receive an email regarding having a water test on my property. I assumed this would be optional ? I do appreciate you are trying to help. But I was disappointed when one of your employees came to my property on a Sunday which was a Bank Holiday. Unannounced!
I felt put on the spot a bit and harassed.
I did not request an appointment.

Hi Neil,
Thank you for your feedback, and we are very sorry for the experience you had.
We do have auditors who visit properties to offer customers the opportunity to take up a free water audit service; however, this service is completely optional and not compulsory in any way.
We are very sorry that this left you feeling uncomfortable or pressured, as this was never our intention. As discussed when we contacted you directly, we appreciated the opportunity to address your concerns and hope we were able to resolve the matter for you. We can also confirm that your details have now been removed from all future communications regarding this service.

Overall great experience!
Overall great experience!
Had a survey carried out to see how Control Flow could help with my water usage.
Very polite and informative during the initial survey.
A plumber was booked for a few days after to install a water saving device to my water meter.
The Plumber arrived and was very professional, courteous and the installation was seamless.
If you want help with your water usage get in touch with Control Flow who are experts in what they do.

Turned up unannounced saying here to fit device on water meter. Had had no prior information and kept talking at me. I ended up letting him in and he did something to my taps. I was trying to wfh at the time and felt completely derailed. I told him that I needed to think about things and he gave me a qr code to scan.
Not surprised to see such a low trust pilot score.
I'm actually fuming now as we have a trading standards sticker on the door saying no cold callers which he completely ignored. Having a name badge does not exempt you from being a cold caller if you don't have an appointment. Even if they saved me £1000 on my bill I don't want this company anywhere near me.

Hi there,
We are very sorry about your recent experience with us, this is not the service we aim to provide to our customers.
We work directly with many of the UK water companies, and your water company will be someone we work with. As part of this project, the goal is to help customers save on their utility bills by having a Water Audit carried out and potentially installing a water-saving device for free (as this is funded by your water company).
Our auditors are trained to visit properties to offer this free service; however, you should also have received a letter or email from us prior to any visit.
Your details were provided to us by United Utilities, as they identified that your property may benefit from one of our water-saving devices as part of their water efficiency programme.
This service is completely optional, and you do not need to go ahead with it, and we are very sorry if you were made to feel pressured. If you could contact us directly with more information, we will look into this to ensure it does not happen again.
