Control Flow water audit

Stuart from Control Flow came round to do a water audit on behalf of United utilities. Stuart was polite, friendly and engaging, and explained what he found clearly and thoroughly but without being patronising. The next steps were also explained well. Very happy with the entire process!

Excellent service from Joel last week

Excellent service from Joel last week. Easy to organise the appointment, turned up within the time slot, took less than 30 mins, polite and helpful, no hassle, and agreed actions before he left.
The follow up is still to happen so fingers crossed that is as good.

am extremely disappointed with my experience with Control Flow.
A representative arrived at my door unannounced and told me that communication had supposedly been sent to me regarding an upcoming visit. I had received no such communication.

I was told that my property may have a leak because of high water usage and was asked to allow an inspection. The representative was very pushy and put me under considerable pressure. After walking around my property, I was told that a new flow control device would be installed within a couple of days. At the time, I initially agreed.

However, after reflecting on the way the visit had been conducted and the fact that I had been approached without prior notice, I changed my mind. I sent an email clearly stating that I did not consent to the installation.

Despite this, just one hour later my Ring doorbell captured them returning to my property and installing the flow control device. A card was then pushed through my door stating that the installation had been completed.

I am extremely annoyed that this was carried out after I had explicitly withdrawn my consent. The installation has also reduced the water flow into my property, which is causing further inconvenience.

I will now be contacting United Utilities to raise this matter and request that the device is removed.

In my view, the whole experience was unacceptable — from the unannounced visit and high-pressure approach to proceeding with an installation after I had clearly stated that I did not consent.

UU audit. Recommended

Stuart Leek was my auditor and he was polite and chatty. The appointment lasted 20-25 mins and he checked all the taps and loos. Found 2 leaks and suggested an attachment for my meter. Very easy. Leaks to be fixed without charge. Could not fault him.

Good job in all senses

The visit was quick, easy and hassle-free. The engineer came to my home and explained the process, then quickly installed the device. It was done before I knew it. I can't see any difference in water pressure. Thank you Control Flow for saving water and money.

Cold Calling at my House

We received a visit from this company unbeknown to us that they would be attending. Apparently 2 SMS 1 Email were sent to us and i can honestly say we received nothing. After talking to the company who were rude and said do you not want to save money, which to be honest was not the point. Myself and husband were not in when your employee arrived and my 84 year old Mother was in the property. She was told it was to read the meter and from United Utilities. They had not got our permission to come in and start changing other things in the house. I had to ring home after seeing on our ring doorbell that you were in my house much longer than just taking a meter reading. You changed things in our taps that made when we turned off a tap it ran for a while after (how is that saving me money?) This is cold calling at its best

My water was working perfectly this morning
You've come round telling us we might have a leak, messed about with the water and now left us with no water at all and we have 3 children.

Now I cant get through to any phones.

In reply to your reply.

No this has not been sorted.
Who ever came out that day from your company causes a leak on my pipe, and united utilities are now saying they need to rip my drive up to fix the leak and they will not be able to put the drive back the way the found it.
Between you and united utilities you are and an absolute shambles

We are very sorry to hear about the experience you had and completely understand how distressing and frustrating it must have been to be left without water, particularly with three children at home.

We understand that this issue has now been resolved, but we sincerely apologise for the inconvenience and concern caused at the time. This is certainly not the experience we want any customer to have.

If you are still experiencing any issues or have any concerns following the visit, please do get in touch with our team with your full details so we can look into this for you and make sure everything has been properly resolved.

You can contact us at watersaving@controlflow.co.uk or call us on 0800 783 700.

Saved me a fortune

brilliant experience all round for me the man came did an assessment realised too much water was coming out of my taps fitted the device all hassle free from me and after having it fitted in April I am now delighted to have had my first bill and have saved a fortune. Nothing to be worried about at all , I hadn't heard of them and did wonder if it was legitimate at first as I had received an email but hadn't seen it . Thanks for a great experience and saving me money.

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.
