Regular boiler servicing is essential for safety, efficiency and preventing costly breakdowns. Metropolitan Plumbing provides thorough annual boiler services across Islington and North London, carried out by Gas Safe registered engineers. A yearly service keeps your boiler running efficiently, protects your warranty and gives you peace of mind through the winter.
Why an annual service matters
A well-maintained boiler is safer, more reliable and cheaper to run. Servicing catches small problems before they become expensive breakdowns, and most manufacturers require an annual service to keep the warranty valid. For landlords, a service also demonstrates that appliances are being properly maintained.
A thorough, professional check
Our service includes checking gas pressure and flow, inspecting the heat exchanger, testing all safety controls, checking the flue and ventilation, and cleaning key components. We finish with a full report on the condition of your boiler and flag anything that needs attention.
We got Tommy and his team in to decommission an old back boiler and fit a new combi and we couldn't be happier. We were looking for a quick turnaround as the job was needed to ensure that the sale of the property went through swiftly. I liaised with Jen on the booking of the job, and all the other information including which combi we would have fitted etc - super clear and quick communication from everyone involved. On the days they were here - Both Tommy and the guys working with him were professional, clean and tidy and got the job done with little to no disruption even while I was working.

Second time I've used Tom & Jen, this time to upgrade my gas supply and replace a boiler. They provided helpful advice when I was deciding which make and model to get, installed it promptly, and helped me with some connectivity issues I had with the Vaillant app. Friendly service and great communication.

Boiler installation
Our experience with Metropolitan Plumbing was excellent. Tom and Jen were friendly, helpful and extremely professional throughout the process of installing our new boiler. The work was done in one day, and it's a relief to have hot water again! Can't recommend them enough :)
Powerflush
My radiators weren't getting hot like they used to, and so I was advised by a friend that I might need a power flush as there may be some blockages. I called Metropolitan Plumbing and they came to validate my suspicions and got the job done the next day. My radiators are back working well now, which is a godsend in these colder months. The gentleman was very friendly and kind, and tidied up well upon leaving. He seemed really knowledgeable. I'll use them again.
Boiler installed
Excellent local service. Highly recommend.
Who done it!
Phoned metropolitan plumbing LTD to find out who we had chosen from checkatrade to come do our plumbing work. No job got carried out here soz, however the lovely happy voice answering my query over the phone that I was asking if they had come to mine to do the work can't remember who did?. Jen WOW, so nice to hear such an uplifting person at 6pm as well gosh, Just because of her manner or personality. How helpful she was and kind on a phone, I need any job plumbed next time metropolitan is the first company I'd try. She a keeper, I don't leave reviews anywhere. Don't ever lose Jen thank you.
Tap replacement
Very prompt attendance. Work carried out quickly and efficiently by very pleasant plumber.
Leaky toilet
I needed my toilet fixed quickly. I posted an add and metropolitan got straight on to me and agreed a time to visit. The job was undertaken professionally and I'm happy with the final result. Good price, good comms, good work. Thanks.
Boiler Installation
The team at Metropolitan Plumbing were communicative, and it was clear that they weren't trying to rip us off with the different options they gave us for our boiler installation. Our old boiler was on it's last legs, and we opted for a new Vaillant which included a 10-year warranty, and they gave me a free servicing the following year on top. The workmanship was impressive, the new pipework is very neat-looking and they worked to complete it in a day's time, which I was pleasantly surprised with. Our new boiler is working efficiently, and they will remain top of my list of plumbers to call.
General Plumbing
I have used the company multiple times, Tom is brilliant tradesman - knowledgeable, tidy, respectful and easy to talk to. Have used Tom for everything including installing radiators, boiler repairs & servicing, shower repair. Since we found Tom (through a recommendation from another plumber who was about to retire) we have not looked any further. He takes your problem and makes it his own. Once I have explained the situation to Tom and know that he's coming I feel a weight lifted as I know it will soon be fixed.
Heating system overflow-pipe
Excellent job in confined space, needing precise made-to-measure pipework.
Boiler showing an F2 fault and making a thunderous sound
From the moment I made initial contact with Jennifer from Metropolitan Plumbing I knew I was in safe hands. Jennifer guided me through a series of questions and a plumber was dispatched to me on the same day! Tommy arrived he was professional, friendly and knowledgeable. Got to the problem immediately and before I knew it the job was completed and my boiler making it's usual sounds. I was so relieved. I will be recommending Metropolitan Plumbers to all of my family and friends without hesitation.
Adding inhibitor to the heating system
Prompt, polite and very efficient service.
Kitchen sink
We were quite frustrated by our kitchen sink, as it was draining slow, even after snaking it several times. Tommy from Metropolitan plumbing was efficient, knowledgeable and quick. He found and remedied the main culprit and fixed the sink in less than hour. The whole process, from the time I made a request on checkatrade to booking the appointment to getting the job done and receiving the invoice was very smooth and pain free. Highly recommended.
Boiler fixed
TW plumbing and heating services fixed our boiler, the work carried out was great. Quick and efficient! Definitely recommended.
Installation of Vaillant combi boiler
I was gathering quotes for a new boiler installation for my rental property, I chose Tommy@ TW Plumbing as he provided the most cost effective solutions for a problematic 3rd floor installation. Whilst I was gathering quotes the boiler completely broke down on a Sunday and Tommy was able to attend the property the same day, unfortunately the boiler was completely gone so Tommy installed a new boiler and completed the installation a couple of days later. I had some headaches speaking to various plumbing companies but Tommy is the Ibuprofen of the plumbing world. Highly recommended!!!!
Bathroom repair
Tommy worked hard to replace a tap cartridge that was difficult to remove because of limescale build up and also repaired a couple of exterior waste pipes that were leaking. I am very pleased with the service.
Replacements of toilet seats and shower wire
Tom, got in touch straight away after I submitted my request on the website. He is an absolutely true professional who came to see the work before hand; which was great. His work is responsibly priced and he knows what he is doing. I would definitely use him again without a doubt. Excellent work!
Installed two new radiators
Tommy arrived at the exact time he said he would and performed the job of fitting two radiators efficiently and to spec. I'd recommend him as a competent, trustworthy plumber and heating engineer. He is really pleasant to talk to and carries out his work with a considered approach. I couldn't be happier with the result. He even returned the next day to balance the radiators for me when I informed him of a cool spot in one of them.
Tom changed the elements of our boiler
Tom changed the elements of our boiler and saved our and our clients a** in a frozen winter day! Smooth, quick, professional. Highly recommend.
Tap replacement
Great job! Quick and efficient, responsive too. Highly recommend.
Powerflush and TRV change
Tommy the plumber is a very professional plumber! Sensitive to your situation (I have a vulnerable in the house and he was very quick to come out and carry out the work for us). Very calm and friendly - nothing phases him even though he may be under pressure. Quick thinking on his feet and takes the time to answer your questions whether or not they're daft! I would definitely recommend him and will be having him back for further work. Fair with pricing and his work comes with a guarantee - Need I say more??? Thank you Tommy, it was a real pleasure to meet you and have you working in my home.

Dripping mixer tap, Boiler noise and rad refit
I have just used Tommy's services twice recently for a dripping mixer tap, refit a heavy rad to it's brackets and investigate odd noise from my boiler. Tommy didn't hesitate with refitting rad, which he did with ease and fixed both the drip with new valves and the boiler noise which has remained quiet since. I found Tommy very polite. He was reliable and very quick in response to booking and visit and his rates reasonable. I wouldn't hesitate to use Tommy's services again as I commend his services.
Fitting local isolation valves to stop water flow if needed
Tommy was brilliant, he was away on holiday when I contacted him but still gave me a date for when he was back to come and view the job. He came at the time he said he would. The original job was to fit a stopcock in my flat but this was not possible but he found another option for me and completed the job on the same day. I would definitely call him in the future and highly recommend him.
Removal of old shower and installation of new one
Job was completed on time, finished to an exceptional standard and the price was great too. Tommy is a really nice, honest guy. Pleasure to deal with.
Plumbing maintenance
I contacted TW Plumbing and Heating after having a very strange problem arise, my cold water tank was heating up, they diagnosed the issue of a faulty kitchen tap which was backfilling the hot water system. I was highly impressed with the experience and time it took to solve this issue. I would highly recommend this company.
Gas Leak and boiler service
I had a gas leak so I contacted TW Plumbing who sent Tom around straight away which I was grateful for as the smell of gas was quite strong!
