Stefan handled our boiler replacement in an efficient manner. He kindly assisted with installing our water filter and noticed some old piping that needed to be removed and overall increased our water pressure, which was great! He communicated well and answered all my questions, which truly put me at ease. Extremely reliable and trustworthy.

Stefan replaced a faulty thermostat for me today. The work was completed swiftly and efficiently. He has done other work for me over the last few years, including fitting a new boiler. I think he is an excellent heating engineer, extremely knowledgable and a very trustworthy and pleasant person to have in the house. I would most definitely recommend him - a top notch tradesman!

Stefan replaced our 17 year old Worcester boiler,which although working ok was obviously at risk of sudden failure. So we could plan a suitable date. His quote was more detailed and included items not given by other quotes. But still competitive on cost. He is clearly extremely skilled and competent It was all done effectively and punctually. Altogether a good experience, and he's also a good guy! No doubt about recommending

"Best in Class": Stefan is the best plumbing/ heating engineer I've ever appointed!

Stefan has undertaken plumbing/ heating work at my property for the last 10+ years. He installed my Worcester Bosch boiler 2.5 years ago and most recently 2 new mobile thermostats. He's also offered kind, informed & precise technical advice/ solutions for more minor jobs. Stefan is head & shoulders above any other tradesman I've engaged since moving to my house in 2006: he's super-smart, always punctual, friendly and professional but, most importantly, technically exceptional in relation to major installation work (and follow up maintenance). I strongly endorse & highly recommend Stefan (& Grand Central)!

Stefan provided quick and professional service at a highly competitive price. He worked efficiently to deliver a high-quality installation, ensuring everything functions perfectly and suits my needs. This included advice on how to reduce the cost by excluding/refunding some items initially ordered (which following discussion we decided I did not really need). The boiler connections, including piping and cabling, are neatly done, the workplace was left tidy and his pricing was significantly lower than other quotes I received (even received a further discount upon completion!). Stefan’s knowledge and experience are evident in his work, and his passion for the job shines through in the results.

I cannot speak highly enough of Stefan Adams. Extremely knowledgeable, very precise, and unbelievably helpful. Heating and hot water supply to house suddenly crashed from old system. Stefan was round immediately and provided a solution for hot water to the house to keep us going. Needed an entire new boiler system from scratch. Stefan explained all the options very clearly, worked around exactly what we wanted and needed, and was very adaptive around our schedule. Came in, got the job done, didn't even hear from him. Came home from work to find everything working perfectly! Any questions I had he was very clear to take into account and explain. Having had a lot of work done over the years, Stefan has proven he is one person I can close my eyes and blindly trust, with a better outcome than expected. If anyone is looking for someone experienced and trustworthy, stop searching and just book in with Stefan, you won't regret it.

Bathroom plumbing

Stefan made time to discuss a plumbing problem over the phone. I have have badly installed plumbing and a saniflo in my bathroom. Stefan was calm, knowledgeable and able to explain what he felt was causing the problem. I felt immediately less panicked. On his way home after a busy day he then dropped in and took apart the pipes until we located the blockage. This was above and beyond what I have ever experienced before and I am so impressed and grateful!

Stefan Adams knows his job back to front. He fitted a condensing boiler in place of an old balanced flue boiler. He reworked the plumbing with speed and accuracy- Stefan is a very pleasant person who by nature works in with the customer. Stefan is down to earth and from the start I was sure he would do a great job- Which he did!- If you need a boiler fitted Stefan is your man!

Big thank you to Stefan for saving us. Our boiler had crashed at a cold time of year and he was round at our house within hours of me texting, with a new boiler delivered the next day and fitted the next working day after that. Ours was not a straight forward job and yet he carefully managed our expectations and exceeded them.

Stefan Adams was working at a neighbour's when we had the nightmare experience I don't wish anyone. Thames Water had a major pipeline burst and the flooding was polluting the Cadent gas main. Instead of gas, our boiler had been supplied with water and had a short when we returned from our vacation. We first did not know what was going on and we had no info on the event which shut 10-15000 households from gas and water services. Our then plumber fiddled around for two weeks and finally recommended a new boiler. He must have been himself abroad not connecting our issue with the Thames Water Christmas surprise for all of us. But it got worse, not only did he scrap the old boiler so I had no proof when I figured the coincidence out, he was still unable to get the boiler he had sold to work reliably and without water bounce sounds which had been most annoying. We had at that point to fire this plumber and we asked Stefan Adams on the street on his way home for help. The next morning he was at our place and had a first look. He got the boiler running properly without any extra noise within half a day. He checked our system and bathrooms and pointed out, that our inversion boiler was taken off the electric due to a product recall and danger of shorts. Unfortunately, the old plumber had not noticed that, so we had lost our warranties the seller of the house had signed up for. We asked Stefan to schedule replacements and he gave us various options, sourced our favourite and installed it at the promised time and in the time scheduled. We had checked the product prices at other suppliers and noted that Stefan's had good quality and excellent pricing. We have been here for 3 years most happy and our annual service visits are reliable and very good quality for small money. Stefan also supplied and installed our replacement Saniflow toilets and the one he recommended works better and is very quiet. Of course he also stepped in on standard plumbing issues and no job is too big or too small for him, that is comfort too. As a retired Judge for commercial law and son of a father who was a plumber I know quality and see if one is a professional, Stefan Adams is, I would bet money on him! My children and their families and our neighbour friends meanwhile all count on Stefan Adams for help, so should you.

Boiler replacement. Stefan is a very reactive person. He did great professional work: always on time and efficient. He provided great support after the installation when my partner and I had some questions. Would definitely recommend Stefan as a good professional trader

We had a few boiler installation quotes but chose Stefan for the work as he was very personable, and honest and gave us good advice and recommendations. We were very satisfied with his work and he was always punctual and responded whenever we reached out to him, particularly when we needed further help with our underfloor heating. He even came around to install a temporary thermostat for us when our builder let us down.

I have known this company for some years and have always found Stefan very helpful and knowledgeable. To save time he always likes to receive photos of the problem, especially the make of the boiler. This is to make sure he has the correct parts. He responds to phone calls ASAP. He is very friendly and professional and I highly recommend him.

Mr Stefan Adams replaced my own boiler earlier in 2023 and it was done on time and on budget. In August 2023 I asked him to replace the boiler of another property I own and he did so. Both are working well. He was very pleasant and helpful. I have asked him to provide the servicing of these two, identical, Vaillant boilers for the years to come. As an authorised Vaillant heating engineer, this extends my warranty to 10 years and he has agreed to do so. I am happy to recommend him.

Stefan replaced my boiler, and despite malfunction the manufacturer worked with them to sort the problem as quickly as possible. He worked quickly tidely and explained the new system clearly. I would not hesitate to recommend Stefan.

The boiler was showing error messages during a very cold snap. I contacted Stefan and he responded immediately. Though not able to attend straight away, he attempted to diagnose via videos and photos. A Vaillant engineer came and did a fix but it turned out that it was not the right fix. Contacting Stefan again, he came the same day with a temporary fix. A new boiler was ordered and this was installed that day. We have since had other plumbing/heating problems and Stefan has been very good with advice. He has exceptional customer service - I can text him at 0600 or 2200 and will have a response. If he is unable to commit to the job, he will recommend a colleague he can trust. He is honest and will explain the job in layman's terms. He is now our go-to guy and is highly recommended.

Stefan provided excellent service when dealing with a leak and failed boiler. He initially asked for photos and gave some initial guidance for free by WhatsApp which was hugely appreciated. When ultimately the boiler needed to be replaced, he provided a clear and accurate quote and talked us through the steps he would have to take and various options. He was patient, and responsive with questions and left me feeling very assured about what he had done and why. There was no pressure to do additional work. I would have no hesitation in recommending him as honest, reliable and thorough, and have used him for some subsequent work on a rental flat too.

Needed new boiler and wanted to upgrade and update the radiators in my flat. Was able to discuss requirements and gain a better understanding in an area where I lacked expertise. Installation was done timely and professionally and the invoice matched the estimate originally provided. Had some after-sales questions regarding the thermostat and again received the help I needed. Also cordial, works neatly and keeps agreements and promises
