From strip-out to finished bathroom
The same bathroom, two stages. The work in between disappears under the tiling, and it is what decides how long the tiling lasts.

Who turns up
The person turning up
When you call Clean Blue Water, the person who answers is the person who does the work. Mustafa Değerli has been a plumber for over thirty years and registered the company in his own name in 2021.
That means nothing is lost between a salesperson's promise and an installer's day. If something is going to be awkward — a flue with nowhere to go, a supply pipe too narrow for the shower you want — you hear about it at the quote, not halfway through.
All forty-four Google reviews are five stars, and nearly all of them mention the same three things: turning up when promised, explaining what is happening, and leaving the place clean.

Process
How the job runs
No surprises. This is the same sequence on a dripping tap and a full bathroom.
- 01
You call or message
Describe the problem in plain words. Photos over WhatsApp help more than you would think — often we can tell you what the part is before we set off.
- 02
We look at it
For anything beyond a simple repair we come and see it. Quoting a bathroom or a boiler over the phone means guessing, and the guess is always wrong in one direction.
- 03
You get a fixed price
Written, itemised, and it does not move unless you change the job or something genuinely unforeseen appears behind a wall — in which case you hear about it before any extra work starts.
- 04
The work gets done
Agreed date, agreed arrival window. Floors covered, old parts taken away, and the site left clean. That last part is what most of the reviews are about.

Reviews
What customers say
Every review below is a real Google review, in the customer's own words.
We recently had a new boiler and full heating system installed throughout our house by Clean Blue Water and are extremely pleased with the result. They explained everything clearly, worked efficiently, and completed the installation to a very high standard while keeping the house clean and tidy throughout. The new system is working brilliantly, and we've already noticed a huge improvement in how quickly and evenly the house heats up.
I needed my radiator removed and Mustafa did a great job, nice and quick. When I first contacted him, he came out the same day to have a look and then booked me in to get the work sorted. I previously had two plumbers come and look at the job, but they refused to touch it because they weren't familiar with the heating system. Mustafa knew exactly what to do with no hassle at all.
He installed a clean water supply and waste pipe for our washing machine by connecting it from the ground floor toilet to the space under the stairs. This allowed us to free up space in the kitchen for a dishwasher. His workmanship was very clean, and he worked quickly and efficiently. He also came fully prepared with all the necessary materials, and we didn't face any issues throughout the process.
I recently had a water leakage issue at home, and Clean Blue Water Ltd provided an absolutely outstanding service from start to finish. He sourced the tap and valve himself, arrived promptly, and completed the job with impressive speed and precision. He explained everything clearly, worked neatly, and made sure the problem was fully resolved before leaving.
Honestly I appreciate so much such hard work Mr Mustafa done today for my bathroom, changing old pipes and replacing the whole shower set. Anyone else wouldn't do that job in 2 hours. Changed the toilet too. Thank you so much.
We recently had a new boiler installed and the whole experience was excellent from start to finish. Everything was explained clearly before the installation and the job was completed on time with no mess left behind. The system is working perfectly and the heating and hot water performance has noticeably improved.
FAQ
Common questions
The questions that come up most on the phone. If yours is not here, message and you will get a straight answer.
No. Quotes are free and there is no obligation. For larger jobs like a bathroom or a boiler replacement we come and look at the property first, because a phone quote on that kind of work is guesswork.
Gas work is carried out through our Gas Safe registered partner, so anything involving gas is done and certified by a registered engineer. Plumbing, heating and bathroom work is carried out by Mustafa directly.
It depends where you are. Around Enfield and north London a leak is usually same-day. Further across London, planned work is booked for an agreed date. If someone closer would get to you faster in a genuine emergency, we will tell you.
The phone is answered outside normal working hours and the business is listed as open 24 hours. For a real emergency — water coming through a ceiling, a burst you cannot isolate — call rather than message.
All major makes and models. Vaillant, Worcester Bosch, Baxi, Ideal, Glow-worm and Main come up most often, and parts for those are quick to source.
Yes. Clean Blue Water Ltd is a registered company (number 13729485) and carries insurance for the work we do.
Yes, including repeat and scheduled maintenance across several properties. Tenant appointments and access are arranged directly, so you are not passing messages back and forth.
Yes. Floors are covered before work starts, old units and packaging are taken away, and the room is left clean. It is the thing customers mention most in reviews, so it is not treated as optional.
