    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. What are the benefits of getting a boiler installation?

    If you have a boiler that is more than 10 years old, it is time to consider changing it. With an old boiler, many issues can arise, which can cost you more than swapping to a new boiler overall. Expensive parts, hard to find them, because most of the manufacturers are not producing them already, and not talking about the higher bills yet, which can be caused by your old boiler.

    2. What is a typical process when installing a new boiler?

    It depends on a lot of things. If you need a boiler installed in the same location, it is easier, than convert your whole heating system for instance. When you call a gas engineer, he will explain the whole process, so by the time you agree on the work, you will know every detail.

    3. What is the first step in getting a boiler installation?

    The first step is usually to choose the company you trust, and like, and talk to them. Here at MML Plumbing, we are available online 24/7 so you can send us your questions, plans, we are happy to give you an online estimation for free.

    4. What are some of the most important customer considerations when installing a new boiler?

    The first thing is most people think of, is the budget. But we always say, buy cheap buy twice. We think the most important thing is to listen to the gas engineer’s advice, as they are up to date on the latest building regulations, and gas safety, they are the specialists, to work with gas appliances, and they know what will suit your home the best.
