Hi Shaun,
Thanks so much for taking the time to leave a review. We are so pleased you were happy with your experience.
We did not receive prior notification…
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.

Control Flow visited our property after we received a letter, and they were very helpful and let us know what was happening during every step of the way.
They were extremely friendly and made us feel very comfortable! I can’t wait to see some potential savings on my utility bills!

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.

"I recently had a free water audit carried out after receiving an email from my water company. It explained this could help me save on my bills so I thought why not.

Great experience
Great service. Control Flow person named Shaun arrived on time, was helpful explaining everything then checked for leaks and fixed a dripping tap in our downstairs toilet. He installed the water saving device in less than 45 minutes. Looking forward to seeing the reduction in our water bill.

Two guys knocked on the door saying they were from United Utilities, my house had been flagged as high water usage and they needed to come in and take a meter reading. The meter had been read a few days ago, my water usage is as low as it's possible to get, the guys were in unbranded high viz. I sent them on their way, to be told I should let them in next time. Called United Utilities. They hadn't sent them. So called police who conducted enquiries and tracked them to this company. They had my name, data breach, and lied through their teeth to try to enter my home. GMP are aware and United Utilities will be getting complaints.

Hi Paul,
Thank you for bringing this to our attention. We are very sorry for your experience. Our aim is to make all of our customers feel comfortable when we visit a property, and we want to make this right.
We work directly with many of the UK water companies, and United Utilities are one of our partners. 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).
We are sorry that you were subsequently advised that the visit had not been arranged by United Utilities. We understand how confusing and concerning that must have been. We can assure you that we do undertake authorised work in partnership with them.
We would also like to reassure you that we do not access or obtain customer information unlawfully. Our teams are expected to always carry identification and clearly explain who they are, who they are working on behalf of, and the purpose of their visit. We also fully respect that no one is ever obliged to allow entry if they feel unsure.
We are reviewing this matter internally to understand exactly what happened in your case, as this does not reflect the standard we expect. Your feedback is extremely important in helping us improve.
If you are able to contact us directly with any further information, we will look into this as a priority.

A ' NO SHOW ' by Control Flow
Like the previous poster I've had a similar experience with Control Flow failing to attend an appointment. Utterly disgraceful. No call, text or email of apology - nout!
I arranged the appointment on the phone and was informed that 'someone' would be visiting my property between 9am - 1pm today 28th/ 01/26.
I've waited in all morning only to hear NOTHING! At least Cenergist turned up last time.
United Utlities will need to sit down and check the integrity of the companies they are recommending. Someone in high office hasn't done their homework- please monitor the failed appointments or as in my case the 'No Show.'
United Utilities may want customers to save water but customers need to save time aswell. I've wasted 4 hours this morning. Unprofessional and 'casual' to say the least.

Very disappointing customer service
Very disappointing customer service. I was pressured into installing a control valve in just one day, with the promise that they would respond immediately if any issues arose. From an hour after installation, I began contacting their customer service team — they took down the details but never followed up or resolved the problem. It’s clear they are focused solely on pushing more installations to generate revenue from the water company, with little to no concern for the customer issues.
