The Best Plumbers in Radlett, Hertfordshire, United Kingdom (2025)

The Best Plumber I have ever come across! SO helpful, polite, informative and professional! Literally googled local plumber, as our toilet was continually trickling. Sent photos to Harry, who then attended within a couple of days and not only fixed the issue, but replaced flush, rusty bolts and system within the cistern. He went above and beyond! Couldn't recommend him enough! Will definitely be reaching out to him for any other plumbing, gas or heating needs.

Harry was reliable, prompt and efficient. Delivered an excellent service at a very competitive rate. Will definitely use him again.

He saved the day for us when we had an emergency. Great communication, came in the same day, sorted the problem fast, and gave us an honest price. I would highly recommend and will definitely use again.

Fantastic service. Clear communication and great value for money. Harry explained everything he was doing and needed to do. He was tidy and delivered a very high standard of work with professionalism. I didn’t know any trades people in the area and would recommend to anyone.

Having been let down by another company, I rang Marshall McGeever and I’m so glad I did! Right from the start the whole team, from Sue in the office to Alan, Robbie and Kev, have been efficient, friendly and a pleasure to deal with. The communication was excellent as was the professionalism throughout the job which was replacing an old boiler, re-working the associated pipework to streamline it, changing and moving a couple of radiators and repairing the heated towel rail. At the end of the installation, Kev took time to explain how to use the controller for the new boiler as well as a couple of other things. I have already recommended them to a friend and I will definitely be using their services again. Thanks Team!

Excellent service! Alan did us a gas safety check because we are selling our home. He was friendly, thorough and efficient and it was all done for a very reasonable price. I would thoroughly recommend!

Marshall McGeever's plumbers were prompt, courteous and efficient. They solved three problems in one go! We highly recommend them.

I recently had a boiler service at my property in Watford, and I couldn’t be happier with the experience. Special thanks to Alan, who provided fantastic service from start to finish. He was professional, knowledgeable, and trustworthy—qualities that are so important when letting someone into your home. Marshall McGeever delivered exactly what I needed with no hassle, and I’ll definitely be using them again in the future. Highly recommend!

We highly recommend LMH. We had a couple of plumbing issues which Lee carried out very efficiently and at a good price too. First class service. Thank you!

Recommend by my electrician. Lee provided an excellent service. He identified additional problems to the one he had been called to do. He was professional and friendly with the explanation of the work required. He took photographs of before and after the work. He cleared and tidied the work area.

From our first contact through to the completion of works, Lee was excellent. He made regular contact, was very flexible in dates for working, and worked carefully and tidily. Our job ended up being more complicated with life-expired pipework, which Lee rectified for us while honouring the quoted price. Just over a month later we have had no quality issues with the work undertaken. I fully recommend him to others for boiler replacement works.

Lee completed two big jobs (central heating and bathroom installation) for me to a very high standard. Lee worked efficiently, tidily and communicated well during both of the jobs. He was very helpful in guiding me throughout my flat renovation whilst trying to minimise the costs incurred. I will hire Lee for future projects and would recommend him to others!

I recently had the pleasure of working with Alban plumbing &heating Ltd and I am beyond impressed with their service. From the initial consultation to the completion of the job, their team was professional, efficient, and knowledgeable. They provided clear communication every step of the way, and the quality of their work exceeded my expectations. Whether it was fixing a leak or upgrading my heating system, they handled everything with expertise. I highly recommend Alban plumbing &heating Ltd to anyone in need of plumbing and heating services. Thank you for such outstanding work!

Best service I’ve experienced with plumber/boilers in general. Asif arrived on time, and was very professional and knowledgable. He immediately identified a fault caused by another boiler company, and ensured the boiler and gas main was working properly. He was also clearly passionate about his profession and experienced in what he does. Would highly recommend this service to anyone who needs emergency or general boiler, gas or plumbing needs! These guys are a credit to the community of St Albans

Our boiler gave up suddenly and of course this happened in December. Alban Plumbing and Heating went out of their way to accommodate us and replace our old boiler with a combi boiler. They worked non stop despite repeated offers for tea and biscuits and delivered ahead of schedule. They take great pride in their work and also made sure everything was working and tidied up before leaving. The work was done to a very high standard. We are absolutely delighted and will keep using them. Highly recommended.

I recently got serviced my boiler from Albans plumbing & heating ltd. I was very pleased rather astonished with the customer service and overall service received from the guys. Particularly Mr Asif, he is very well versed with the knowledge of the boilers and the technicalities of his field. Overall, I must say it was wonderful experience. Excellent service by excellent people.

So happy with Martin and Luke who have been our plumbers for the last 12 years. They’ve installed 4 bathrooms for us now (in our previous and current home), as well as improvements to our heating and hot water, including radiator pressure wash and installing a mega-flow for high pressure hot water. They are always lovely to have around, friendly and hard working. They recently renovated our ensuite, as well as installing the new bathroom suite, they removed the old, and when they found the old shower had been leaking for the last 20 years and started to rot the floor joists they fixed all this before installing the new bathroom. They also did the tiling and installed an electric heated floor mat which was screed in before the vinyl floor went down. We were so happy with the job, the finish is excellent and they went above and beyond fixing problems they found along the way.

My Dad who is elderly and disabled called out these guys to look at control bar in his shower recently...amazing quick and responsive service. Dad was happy. A couple of weeks after had to get Luke out again to check something as surrounding flat had a leak....they were trying to blame Dad!...Luke came out within half an hour and checked everything over...finding no problems at Dad's. Am REALLY grateful for there professional approach and kindness towards my Dad. Really nice guy...and so lovely with Dad would recommend 100%

Absolutely delighted with the service that I received from Martin and Luke. They asked my wife and I exactly what we wanted before they started on our en-suite and exceeded our expectations. We're so happy with it and couldn't recommend them enough.

Called MJ plumbing and heating to help with a shower issue in my flat. Only cold water was leaving my shower, they responded quickly and got the issue sorted quickly too. Not had a problem since. Highly recommend. (also wore masks and gloves without having to ask)

Great service from Avenue Heating. Charles attended within the hour and gave a very professional and helpful assessment of my boiler. Everything was explained clearly and I was able to make an informed decision about the situation. Callum fitted my new boiler within a few days and was also extremely professional, hard working and reassuring. I can recommend this company highly and am happy with every aspect of the installation.

So pleased to have finally found a reliable company to look after my heating system. Recently have experienced issues with my hot water and an engineer visited the following day and rectified the problem. Nothing was too much trouble and their attention to detail was exemplary. So grateful to Alex and a big thank you to Donna in the office who kept me informed about what was happening

I’ve used Avenue Heating a few times to repair my old boiler, and they were always great. When the old boiler finally stopped working, we decided to install a new one with them, and everything went smoothly. Few days ago, our new boiler had a fault, and they responded very quickly and came yesterday. The issue was a condensate pipe blockage, which was causing the problem, and they fixed it straight away. Charles, the engineer, has been fantastic every time he comes—professional, knowledgeable, and efficient. I highly recommend Avenue Heating for their professional service, fair pricing, and quick response times. A reliable company you can trust!

We needed to replace a 30yr old boiler. The job was assessed by Ellis clarifying what was needed and what should be additionally considered. The items were individually costed and similar to other quotes we had. The work was done by Ellis giving continuity and he dealt with any issues very competently with minimal disruption to our own schedule including him having to work late on one occasion. Thoroughly recommend the service and we would happily use Avenue Heating again.

Jake took care of everything, from discovering the leak and removing the damaged materials to installing a new floor and everything else. He was full of helpful advice, organised the flooring fitter and decorator, and always delivered on time. Jake was tidy, very polite, and friendly, making us feel assured we were in good hands. He clearly holds himself to high standards, and we’re very happy with the finish. Highly recommended!

Recently updated our downstairs cloakroom. Its small so hard to know what to have re storage. Jake was helpful in advising options. Marc and Owen came to carry out the work. They made sure flooring was protected, did a fab clean job. Both very polite and helpful. Also a shout out to Croxley Plumbing. Gwyn was really helpful and patient when helping me choose what would work in the small space!

Jake and his team did a fantastic job on a sizeable bathroom repair. They were professional, communicative, and easy to work with—exactly what you want as a landlord. It was a refreshing experience from start to finish, and I wouldn’t hesitate to recommend them. Tidy high quality finish done to time. Highly impressed!

After seeking a recommendation from a close neighbour I employed the services of Revive Plumbing services. My first contact was with owner Jake who visited my property within a couple of days for a survey which was followed up a email with my quotation. We agreed a start date and during this period the communication was excellent. The fitter Jordan was fantastic and a very multi skilled young man who did not see problems only solutions. His level of finish is high end and he showed great patience in answering my many questions. I highly recommend Jake and Jordan.

Elis replaced our boiler, which had reached the end of it's economical life, together with a reworking of the way the radiators and underfloor heating are connected and controlled. Elis really understands how a modern system should be put together. Quite a tight space to fit everything in, as we still wanted space to store the vacuum cleaner and retain shelving. Polite, knowlagable, and very helpful. 5*

Elis is very professional arriving within his ETA . Explaining exactly what he is going to do and then carrying it out. Supplied & fitted a replacement bathroom basin tap plus two isolation valves. Reliable & very pleasant. Top plumber & heating engineer.

I'm a Landlord Living Abroad so managing properties and finding Good Trustworthy Tradesman who don't try and inflate the initial quote is rare! Top Job Very Happy :)

Elis from Home Comfort Assured is an outstanding Plumber. We had several complicated heating issues that Elis attended to and resolved quickly and efficiently. He took time to explain why various things had failed in our heating system and presented clear and understandable options on how to proceed. Not only is he an excellent and knowledgeable heating engineer, but he really cared about ensuring that we were happy with what he was doing, and he spent all the time that was necessary to resolve some complicated problems so that we were not left without hot water or heating. He stayed quite late to fix things but did not charge us for all his time, caring more about customer service than profit - so rare these days. He is my go-to plumber from now on, as I have not come across anyone better in over 40 years and I can recommend him highly to anyone who wants a great plumber/heating engineer that can be trusted to do a great job quickly and efficiently.

We completely trust Sylwester with all of our gas and plumbing repairs. He is extremely professional and thorough, and keeps us fully informed throughout the whole process. Nothing is too much trouble for him. Highly recommended!

I found SG Services when we moved into our new house last year and I’m so happy I did. Sylwester has done lots of work in the house, including installing new radiators, fixing our shower and installing a new nest system and each time he is nothing short of professional, knowledgeable and very honest. I don’t hesitate in recommending SG Gas Services if you’re in need of a plumber.

Great work by Sylvester, had a issue with my boiler system and was recommended to contact SG gas services. Could not praise him enough, will definitely be using he's services again. Perry

I would highly recommend the services of SG Gas Services. I have used Sylvester for many years and have always found him to be professional, honest and efficient in all his work. His labour rates are competitive and reasonable and he always does his best to please. If your job is urgent he will respond ASAP and he will always return calls and messages promptly. After completion of his work he will provide an excellent ‘After Sales Service’ should you need it. Apart from all this, he has a polite, calm manner that always puts you at ease and will patiently explain anything you need to know about your particular job.
