    WOW.... what fantastic service... Levy arrived at the time I was given. He was totally professional, in capping my gas pipe. Unfortunately, he had to remove it all, as previous engineer left it short! in order for an Induction hob to be fitted. He went above and beyond what he came to do. He also checked my boiler as he was not happy about the pressure.. would definitely use MML again.. and I can highly recommend them..

    Did not have a 'regular' plumber in north London, so took a punt and mailed a few from Google search. MML came back immediately, great communication, good price for the work (which was not a simple job) and the engineer was excellent - friendly, professional and super hard working. Three long days for what was hoped to be a two day job, no moaning when it became more complicated (due to the old system being problematic), definitely reccomend.

    This was my second time using MML Plumbing. The plumber arrived on time, assessed the problem and did his best to resolve it. It was all completed within the hour and I am very pleased with the result. A very clean and tidy job done.

    I called MML Plumbing to investigate a boiler fault and they were very helpful and quick to respond. The engineer, Mike, arrived earlier than expected and was friendly and professional. He thoroughly explored the problem(s) and fixed what he could. Unfortunately, it is a problem that the manufacturer will have to deal with (due to availability of parts). Mike was very honest about this and, here is the amazing part, he did not charge me today as he couldn’t fully resolve the issue! Am so impressed and would not hesitate to call this family business out again.

    MML Plumbing did an excellent job. The engineer was very thorough with the safety checks, boiler service and Gas Safe certification of two properties he worked at for me. Very good value for money, very good service. Admin staff were courteous and friendly over phone and email and we very prompt with sending all paperwork and copies of photographs to me. Highly recommended!

    Fantastic service! Our boiler stopped working unexpectedly. MML Plumbing came quickly, diagnosed the problem and resolved it immediately to make sure we weren’t without radiators for too long. Very impressed with the expertise, friendliness and communication. They also gave us tips for maintenance. Highly recommended!

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

    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 up online, by their gas safe number.

    Always make sure, your family and you are safe, 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, the position you would like to install, (the same place or a different location). Also, an important matter, 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, 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.

    3.How long does a boiler swap take?
