"Plamen was on time and extremely courteous, explaining everything he was doing. A part had to be ordered and Plamen was able to return to fit in good time.

"The mixer tap in our kitchen was dripping so Plamen replaced it with a new one. He was very friendly and courteous but also worked very efficiently with little fuss or delay. Everything was tidied up afterwards and he took the old mixer tap away with him which was ideal. We were very pleased with his work."

Plamen from TopFlow services installed a new boiler for me and did an absolute amazing job. Gave me the right recommendations for the correct product suitable for my needs, worked extremely clean, left the kitchen in the same state as he found it. 3 years ago he also refurbished the full central heating system for me, replaced all radiators and some of the pipework. I would always recommend to a friend!

Highly recommended! I used Plamen a number of times already. I am a landlord in Sutton and he is my number one contact if anything urgent happens and requires a repair. He stopped a major leak over Christmas when other contractors were not available, fixed plumbing after his working hours, repaired a boiler in one property when I thought it was not repairable and changed a boiler in a second property. He is always on time and available if there is an urgent call, reliable and a good professional. He goes into all the little details explaining how boiler works - so you understand what causes an issue. Genuinely a good guy! Thank you Plamen for all the work you’ve done!

We recently moved in to a 1930s house that needed a lot of plumbing work done. We've had leaks, issues with the boiler and new bathrooms to fit. I saw reviews about TopFlow online and was very impressed. We initially called Plamen on a Saturday due to a bad leak. He arrived within an hour, solved the issue and even recommended further improvements. Since then, Plamen has spent many days working at our house sorting out blockages, leaks, new fittings and is currently in the process of installing a whole new ensuite. He is professional, tidy, kind and more than happy to help - he goes above and beyond to make sure you are making the right decisions. We have been so happy with his work and will continue to use him and recommend him to family and friends. Thanks Plamen for everything you've done so far.

Plamen has always done a great job for us. He has done gas, plumbing and other works for us and each job was done very well. He is thorough in his trade and always keeps the client's interests in mind. I will recommend him 100%.

Great work from the engineer to replace our radiator valves. He arrived on time and finished the work very quickly. We have used Topflow services in the past and are always impressed with their professionalism.

I am so happy to have found Plamen! He is an exceptional plumber and works so hard and conscientiously. His communication is excellent and he keeps me informed and updated throughout. His prices are very reasonable and all costs are transparent. He is completely honest and discusses and explains all work before commencing, but he also explains everything throughout the work. I recommended Plamen to my neighbours and a friend, and they are equally impressed and delighted with the high standard of Plamen’s work. Plamen has completely transformed the plumbing and heating in my home. He flushed the whole system, upgraded the radiators (see attached photos), replaced radiator valves, improved the function of the shower, changed the kitchen tap (see photo) and he now services my boiler on a yearly basis (see photo). I wouldn’t consider using any other plumber as Plamen has consistently demonstrated a very high standard of expertise, skill and knowledge. He is also a really lovely guy.

A very professional job. My new boiler is working perfectly since being installed. He explained fully what the work entailed and kept me informed of what was happening. Very happy with the work done.

Plamen did an excellent job replacing the toilet in our house today. He was here last week and also repaired our gas boiler. His service is always of the highest quality, and it is always spotless when he leaves. I would definitely recommend him to all of our friends.

Plamen from Topflow Services is an absolute top-class professional, who delivers a very high quality service consistently and reliably. He is my "go to" plumber for any repairs that we've needed in the house, including our immersion heater thermostats and general plumbing, including an excellent job installing our daughter's new showern recently. He is friendly, polite and prompt. To me, he is by far the best plumber in the Epsom area. It is quite difficult I've found to find someone who is as deeply skilled professionally, but also trustworthy and provides a great value service too. Plamen meets all of these criteria and more. I highly recommend him without any reservation - lucky to have found him!!

I’ve been reaching out to Plamen every time I needed help in my flat, and he has always been kind, friendly, and easy to communicate with. He has redecorated my flat, renovated the bathrooms, assembled furniture, and mounted TVs, paintings, and much more; all with great care and true professionalism. He’s the first person I would contact for any job, big or small!

Plamen was polite and accurate in diagnosing with why my hot water tank was not working. I was not convinced but he was correct about my thermostat being the culprit. He replaced it quickly and efficiently. I highly recommend him.

Plamen was great. Despite the issue occurring between Christmas and New Year, he came out to us urgently and rectified the problem with our heating system with maximum efficiency

Plamen came the same day I called, found the problem, sourced the replacement part and returned to fix the boiler. I would highly recommend him and I will be getting him back to fix a hive system to my boiler.

Before you hire a gas engineer

By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
