Dean installed a new water heater for me. When I contacted him about doing this, he researched different options for me and went through the pros and cons of each. He arrived on time on the scheduled day. He was efficient and thorough throughout and at the same time personable and friendly. I have used Dean before and have no hesitation whatsoever in recommending him.

After my combi boiler stopped working I contacted Dean at Limitless Boilers, whom I have used before for boiler servicing and repairs. He said the boiler was not worth repairing, we both knew it had been hammered and not serviced by the previous owners of the house. He rearranged his schedules so he could install a new combi boiler the following day, as I need hot water. He really knows his stuff, works cleanly and efficiently without cutting corners. Old boiler removed and taken away, new boiler installed, tested and working, documentation completed within 5 hours - all on a really hot day. Fantastic customer service, quality of work and not expensive.

I've used Dean and Limitless Boilers for a few years now, ever since our boiler gave up the ghost and we needed an emergency replacement. Thankfully he helps with household plumbing too and as ever, He answered our call and booked an appointment for us in short order when our cistern and outdoor tap went awry. He's very friendly and efficient in all his work, discusses possible options and arrives on time and does a very professional job (which he cleans up afterwards). I consider him and his work good value for money and have no hesitation in recommending him as he's been on our books for a number of years now.

I was extremely impressed with the service Dean provided. My boiler had stopped producing hot water in the bathroom, and Dean responded very quickly to my initial enquiry. He identified the fault almost immediately and resolved the problem with minimal fuss. The repair was completed efficiently and to a very high standard, and everything is now working perfectly. Dean was friendly and courteous throughout while remaining focused on completing the job properly. I would have no hesitation in recommending Dean to anyone looking for a knowledgeable, reliable and professional plumber.

Limitless boilers first helped us out in an emergency when we had our new baby granddaughter to stay and had no hot water…they responded really quickly and sorted it all out for us. Since then they have replaced our old boiler and updated our heating system. Dean is fantastic at diagnosing problems and understanding what’s needed. They are friendly, trustworthy and conscientious. The standard of work is excellent. Their pricing is fair and accurate - things don’t escalate. I cannot recommend them highly enough.

We had our old boiler replaced with a new Worcester Bosch boiler and couldn't be happier with the whole experience. Dean and his team were professional, explained everything clearly, and took real pride in their work. It's great to deal with a local business that genuinely offers a personal touch. I'd happily recommend Limitless Boilers to anyone looking for a boiler installation in St Albans.

Dean at Limitless boilers is a highly recommended Gas Safe registered engineer. From the initial booking through to completing the work, the entire experience was professional, efficient, and stress-free. He gave me a time of arrival, on the day, called me when he was on his way, arrived on time, explained everything clearly, carried out the work to an exceptionally high standard, and left the area spotless afterwards. Dean takes great pride in his work, genuinely cares about safety and customer satisfaction He is friendly, honest, and was happy to answer all of my questions without any pressure. Dean gave my combi boiler an inspection, carried out remedial works required to ensure it fully met Gas safety regulations, full service and provided a Gas safety certificate. It's refreshing to find someone who is not only highly skilled but also reliable trustworthy, and respectful of your home. I have no hesitation in recommending him to family, friends, and anyone looking for a first-class Gas Safe registered engineer. Outstanding service from start to finish - definitely a five-star experience! He also does plumbing work too by the way.

Dean grom Limitless Boilets Ltd, proved himself something of a hero to us last year when he came to do a repair and found himself in the middle of of a medical emergency. He calimly completed the work and left so when we needed another repair doing last week he was the only person I requested to do it.Job assessed, part ordered and completed very quickly . No fuss, no muss.

We had a boiler issue and needed someone out quite quickly. Limitless Boilers team came round the same day, had a look, and got it working again without any fuss. Everything was explained in simple terms and the engineer was easy to deal with. Really glad we called them — all sorted and no stress in the end. Would happily use again and recommend locally in St Albans.

Really pleased with the service. Our hot water stopped working unexpectedly, so we called for an emergency repair. The plumber arrived promptly, quickly found the fault, and was able to replace the port valve straight away as he had one in the van. It was a huge relief to have everything sorted in a single visit. Friendly and knowledgeable - a very positive experience overall.
