We recently contracted Vasil to help fix a gas leak. He was an incredibly quick to respond and did a fantastic job installing new pipework to a very high level. We were very grateful for his level of professionalism and pace of work! We would highly recommend using Vasil and we will certainly do so for any future jobs we have.

Boiler replacement A ok

Very professional and good communicator. Basil walked us through all the stages of the installation. Very old boiler (25+) with old electrical system which probably made the installation difficult. However the job was brilliantly done. Definitely recommend.

Professional, Honest and Reliable Gas Engineer

Vasil installed my boiler about 6 years ago and ever since he conducts my annual boiler check ups. He installed the equipment in a very difficult place, and throughout the years has also helped me with gas regulation installations and other gas and heating related matters. He has always provided very good recommendations that are in my interest. Vasil is a serious professional, punctual, highly skilled, and reliable. What stands out is his honesty and readiness to help and find solutions. Highly recommended, I would not trust anyone else with my gas and boiler matters.

Effective and reliable expert

Vasil came recommended to me by my trusted builder when I needed to replace my flat’s hot water cylinder. Vasil provided honest expert advice and guidance as to what was the most appropriate system to purchase and then completed the agreed work to a high standard. I would highly recommend their services and would definitely use again for any future work.

Outstanding Service

Outstanding Service - My Go-To for All Boiler Installations I cannot recommend Boiler Engineer 4U LTD highly enough! Over the years, they've installed nearly 10 boilers across my rental properties and my own home, and every single experience has been exceptional. What impresses me most is their consistency. Whether it's a rental property or my personal residence, the quality of workmanship never varies. The installations are always completed quickly without cutting corners, and the craftsmanship is built to last. I've never encountered a single issue with any of their installations, which speaks volumes about their expertise and attention to detail. As a landlord, finding a reliable, efficient contractor is invaluable. Boiler Engineer 4U LTD has proven time and again that they're professionals you can trust. Fast turnaround, flawless execution, and installations that stand the test of time - what more could you ask for? If you need a boiler installation, look no further. These are the people you want for the job.

Outstanding service from start to finish

I cannot recommend Vasil highly enough. From our initial consultation to final installation, his professionalism has been exemplary. We originally contacted Vasil to repair our Viessman combi boiler, but after his thorough assessment, we agreed that replacement would be the better option. He carefully checked our gas supply and identified that our existing pipe wasn't 22 mm, advising us to select a boiler appropriate for our current setup. He explained we might need a larger gas pipe if adequate pressure couldn't be achieved during commissioning. During the process, Vasil suggested we remove and cap off our old gas cooker in favour of an electric induction hob. This thoughtful recommendation saved us the expense and disruption of running a new gas pipe across the room. He cut the gas supply to the cooker at no charge and even installed CO2 alarm without as usking - going above and beyond what was required. Vasil's dedication was remarkable. He returned on a Sunday to install our new boiler and worked though without breaks until the job was completed to perfection. Throughout, he was easy to communicate with, friendly and demonstrated exceptional knowledge of his trade. Five-star service in every aspect!

Highly professional

Having worked with Vasil over a period of a few weeks on two projects and getting to know him and his background it became clear to me that he really stands out from the crowd. He is much more of an engineer than a boiler man which can be hit and miss. He is also a very friendly man. I must admit that initially I did not fully appreciate that as I have had many not so good experiences with tradespeople but he is the real deal. I can only recommend him. And given the quality of his work he represents very good value for money.

Happy Clients for Life

Amazing service! So fast, knowledgeable, professional and very good value. We had a problem with our under floor heating and not only was Vasil able to come right away and diagnose the problem, but he also found a temporary solution for our heat while we waited for the new pump he ordered to arrive. He came back the next week and installed the new pump and now everything is working perfectly again. I would absolutely recommend him to anyone! Such a trustworthy, reliable and lovely man. We are happy clients for life!

Excellent boiler service!

I had an excellent experience with Vasil, who came to service my boiler. He was punctual, polite, and very professional throughout the visit. Vasil took the time to explain what he was doing, carried out the service efficiently, and made sure everything was working perfectly before leaving. It’s great to find someone so knowledgeable and reliable, I’ll definitely be calling him again for future maintenance. Highly recommended!

Great work

I highly recommend Vasil of Boiler Engineer 4U. I had 5 quotes for an urgently needed new boiler and am very glad I chose him. Nothing was a problem and he installed it in a few hours. He also fixed a stuck radiator valve and as a great bonus for me he found the indoor stopcock which no other plumber had bothered to find in all my years in my house- they just turned the water off at the outside mains which was not ideal. He also will be doing the annual service. He was incredibly tidy and cleaned up after he finished. I will definitely be using him for all plumbing needs in the future.

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Verify at the sourceCheck them yourself

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.

Check the WaterSafe register
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
