    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!

    Replacement of fill valve. Efficient, professional and pleasant plumber.


    You might have a boiler that is inefficient, old or just not working well. If your property has the following 10 signs, you may need to install a new gas boiler.

    1) Your heating and hot water bills are higher than normal
    2) You can hear banging sounds from inside the house when it’s on
    3) It takes forever to heat up in cold weather.
    4) There is an unusual odour coming from the vents when you turn on the system. This could be because of bacteria buildup or gas leaks.
    5.)The boiler is making an unusually loud noise when it’s on or off
    And these are just 5 reasons from all.

    Choosing the right boiler for you can be a difficult task. There are many different factors to consider, including efficiency, heating capacity, and installation requirements.

    -Firstly, you should consider whether or not your current boiler is in good condition. If it needs replacement soon then this may be a better option than choosing one now.

    If you’re looking for a professional, affordable gas engineer in Friern Barnet then contact MML Plumbing today.

    To make it easier on yourself we offer 3 ways to get in touch with us:

    PHONE: 020 8355 0840, EMAIL: or QUOTE: submit your job in the quote online form!


    Choosing between a heating system conversion or boiler replacement/swap can be difficult, especially if you are not well-versed in the different methods and materials. A boiler replacement takes less time to install and is typically less expensive than a complete heating system conversion. 

    Ultimately, the decision between a boiler replacement and heating system conversion is dependent on factors such as how good shape is your system, where the boiler is located, your hot water and heating needs and how good quality boiler you want to install, 

    If unsure about which solution to go with, it’s best to consult a professional, like MML Plumbing ltd. We are happy to guide you.
