    Used MML Plumbing for the first time today. Administrator in office was easy to deal with, efficient and helpful. Plumber arrived on time as arranged, fixed the problem and explained what he had done. Quick, tidy and courteous worker. What I also especially liked was that I was given an actual confirmed time when he would arrive and not one of those two or three-hour 'window slots'!

    MML Plumbing successfully completed the installation of our heating system in our expansive 8-bedroom residence. The placement of the boiler and cylinder was expertly executed in the basement. They meticulously laid new piping throughout the house to facilitate radiators and hot/cold water faucets. The recent commissioning of the system has resulted in its exceptional functionality. Their impeccable organization and absence of any delays were notable. We definitely plan to engage their services again in the future.

    In North London, it can be hard to find a company that you can trust and provide quality work. We called MML Plumbing to install a system boiler and a hot water cylinder. The installation was done in a few days, and now everything is fine. They left the area very clean. I highly recommend them.

    ⭐⭐⭐⭐⭐ I am thrilled to leave a 5-star review for MML Plumbing's advanced leak detection services. They were able to find a leak that three other plumbers had missed. Their use of thermal imaging and acoustic leak detection tools set them apart from other companies in the area. What impressed me the most was their commitment to resolving the issue without causing unnecessary damage, while other companies suggested tearing apart my ceiling. Their services are not only effective but also affordable.They are a reliable and trustworthy company that goes above and beyond to solve plumbing problems. Thank you, MML Plumbing, for your expertise and exceptional service. I will definitely turn to you for any future plumbing needs. Hollie xxx


    1. How much does a plumber charge to install a boiler in  Finchley?

    This is a very common misunderstanding, and we would like to help you out with useful information and make this clear. ONLY a qualified gas engineer is allowed to touch, check, repair, or install a boiler. There is no other qualification making someone eligible to work with gas. Our specialists are registered by the local gas authority called GAS SAFE, which you can easily check online, by their gas safe number.

    Always make sure, your family and you are safe, and always use a professional to work with gas. Contact us today, and stay safe! 

    2. How much should a new boiler and installation cost?

    There is no exact price for this. Everything is depending on the boiler brand you wish to choose, and the position you would like to install, (the same place or a different location). Also, an important matter is if you want to keep your existing system type, (combi boiler to combi boiler) or you might want to change it. (heat-only system to combination system) for instance.

    And more good news to come. We also have to check the gas pipes, and your existing system’s condition to give you an exact price.

    That is why we created a customer-friendly button online, you can contact us 24/7. By answering our questions, we can tell you a 90% accurate installation price. However, to give a 100% accurate price, we have to visit you.

    In most cases, you can expect around 1 day on average. At most, it usually takes 2 days; installation is fast and often within a few hours when like-for-like units are swapped to one another.
