    Which is the most suitable for you? The first thing that’s important is determining the need for your new installation. It all depends on your property circumstances, your old system, your property, your budget, your previous boiler, your heating system’s condition, and last but not least, your preference. 

    We will go out and do the necessary tests in order to provide you the best option possible for your home.

    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.

    MML Plumbing were really efficient, turned when he said he would, gave an accurate quote and did the job on time with no mess. I would definitely recommend them!

    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!

    This is the third time I have used MML plumbing. They are by far the most helpful and efficient plumbers I have used. They have installed a boiler, replaired radiators, replaired and shower and toilet for me - all work is to a high standard and every repair explained in full. HIGHLY RECOMMEND

    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?

    We can’t tell enough. Only a gas safe registered engineer is competent to work on gas appliances, whether it is a boiler or a gas hob.
    Call us on 020 8355 0840, to request a visit by our gas engineer.

    2. How do you find a good installer? – You just found one.

    We mentioned above all the advantages we are coming with. There is a lot of things to check and consider before you hire someone.

    1. We always recommend working with a limited company like us. First of all, Ltd’s requires to have Public liability insurance of up to £ 2 million.
    2. Ltd’s have more investments, so they have more to lose. This fact makes us being more reliable, and dependable than others.
    3. Good presents are everything. Read the reviews everywhere. Our customer’s experiences are displayed clearly.
    4. Website. Some of you know the amount of work and expense you need to spend to maintain and advertise a business website. I think this investment shows the business’s intention. If a tradesman just presents on free sites and advertising for free, that is not a good sign.
    5. Recommendations. Again, reviews, and word of mouth. We have worked with many homeowners, businesses and landlords across Barnet, and within North London. Probably visited your neighbours or family members as well.
    6. Contacts. For us the appearances are crucial. Small things such as personalised email addresses, or having a landline office number can mean a lot. This again shows, the company’s intention, if they are investing hundreds and thousands of pounds to grow their business, or not and happy with a mobile number to serve their customers.
    7. When it comes to boiler installation, the first thing is to verify the company REGISTRATION NUMBER. Do not hire someone without the right qualification to install your boiler, because their offer is a little cheaper. It can cost your own safety. You can see our Registration number at the bottom of our website. We also recommend asking the gas engineers gas safe card with a photo, on the appearance. Unfortunately, it is a very common method by companies, to send out someone with only experience but no qualification. The company itself is registered, but not the engineer. Our engineers are registered individually, please feel free to ask for their photo cards upon arrival.
    8. Companies House check.
      As we said earlier, it is always worth using a limited company rather than anything else. However, there are still some companies acting as a company, and they are already dissolved. Please always check, who you are inviting into your property.
      Just to mention a few tips before you consider getting a big job done like a boiler installation to think about. Hope it helps.
