    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.

    1. Can you have heating and hot water at the same time?

    A single boiler is located in the basement of a house which heats water for pipes to travel through and heat different rooms. A combi boiler provides hot water as soon as you turn on a tap, making it more efficient than central heating systems that take longer to have it.

    2.Can I drain my radiators and still have hot water?

    You can’t have hot water from the boiler if the system has been drained. However, you may have an electric immersion heater that will provide enough hot water to take a shower or handwashing.

    3. How long will the water stay hot in a water heater without power?

    We would recommend not showering until the power is restored, as tank-style heaters only have a 1 to 2 hours reserve of hot water, to avoid legionella infections.
