What Our Customers Say

Great and efficient boiler service, fixed price so no surprises. Very professional
Danuta Miloszewski

Used MML Plumbing for the first time today. Administrator in office was easy to deal with, efficient and helpful. Plumber arrived on time as arranged, fixed the problem and explained what he had done. Quick, tidy and courteous worker. What I also especially liked was that I was given an actual confirmed time when he would arrive and not one of those two or three-hour 'window slots'!

MML Plumbing successfully completed the installation of our heating system in our expansive 8-bedroom residence. The placement of the boiler and cylinder was expertly executed in the basement. They meticulously laid new piping throughout the house to facilitate radiators and hot/cold water faucets. The recent commissioning of the system has resulted in its exceptional functionality. Their impeccable organization and absence of any delays were notable. We definitely plan to engage their services again in the future.

In North London, it can be hard to find a company that you can trust and provide quality work. We called MML Plumbing to install a system boiler and a hot water cylinder. The installation was done in a few days, and now everything is fine. They left the area very clean. I highly recommend them.

I have been a landlord for 15 years and used many labour staff in my years. I started to use MML 6months back and now used them 5 times: 1) They are always on time 2) They are respectful 3) I trust their quotes - they do not "make up work" 4) They communicate well on both email and text 5) They are very organised and polite I have dealt with so much domestic help over the years so i know the benchmark - MML are way above Jay (Camden)
MML fitted a shower. Good price, courteous and thorough communication and excellent standard of work. I will call them again if I have plumbing related work

⭐⭐⭐⭐⭐ I am thrilled to leave a 5-star review for MML Plumbing's advanced leak detection services. They were able to find a leak that three other plumbers had missed. Their use of thermal imaging and acoustic leak detection tools set them apart from other companies in the area. What impressed me the most was their commitment to resolving the issue without causing unnecessary damage, while other companies suggested tearing apart my ceiling. Their services are not only effective but also affordable.They are a reliable and trustworthy company that goes above and beyond to solve plumbing problems. Thank you, MML Plumbing, for your expertise and exceptional service. I will definitely turn to you for any future plumbing needs. Hollie xxx

Quality New Boilers That We Install in North London

We help you to understand what system you have.

When calling us, you will already know some boiler basic knowledge, and provide us with as much detail as possible.

Combi Boiler Installation

All our engineers recommend and install combination boilers for all smaller properties and flats. The combi boiler is suitable where are only one bathroom and no high demand for hot water.

We will give you an outstanding free online quotation beforehand. Every job is very important to us, we like to meet you in person and check the system and the old boiler condition. We take care of your safety! Our trusted gas-safe engineers will check all your gas appliances. Thus we can give you a more accurate quote and advice on what is the best boiler installation option for your North London property!

Every job will be inspected by gas-safe registered engineers!

The combination boiler is suitable in cases where there is only one bathroom and no high-demand usage.

Benefits of the combi boiler:

  • It is the best choice for small spaces, which is very frequent in North London.
  • Because there are fewer pipes, it is also cheaper for us to install compared to a system boiler.
  • The cold water is fed directly from the mains, and you can have powerful pressure in the shower.
  • The biggest benefit of combi boilers is that you don’t have to use a separate storage tank, which saves you a lot of space.
  • In this case, you will save hundreds of pounds every year.
  • You can have a powerful shower, without the need for a separate shower pump. Combination boilers are the most energy-efficient & cost-effective boilers on the market.

A few disadvantages of this high-efficiency combination boiler:

  • You need excellent mains pressure for the combination boiler to perform.
  • With the combi boiler, you can use one tap or shower at the same time.

Get ready for an energy-efficient upgrade! Book your free online boiler installation estimate today and unlock the benefits of our high-efficiency boilers, including warranty coverage of up to 10 years and savings in the long run.

System Boiler Installations

We recommend the system boiler installation in homes with multiple bathrooms

  • This boiler can deal with a high demand for hot water, so if you recognise yourself, this is the best boiler type for you.
  • Supplying water to more showers at the same time with the same efficiency and power, to serve more people comfortably in the house.

It is ideal for homes with no space in the loft.

  • For the boiler, we only need to install 1 storage cylinder, which gives more free space.
  • The system boiler can replace the regular boiler.
  • The boiler is heating your radiators. The hot water is produced and stored in a separate storage tank.
  • These system boilers are like regular boilers.
  • The big difference is that the system boiler takes the water directly from the mains.
  • This boiler is a compact unit but it will supply a high volume of domestic hot water and it can fit in the kitchen cupboard.

With this boiler installation, we will help you by boosting your system and having powerful pressure in your shower! You will have it all.

The system boiler advantages:

  • We don’t have to install a cold water tank in the attic.
  • Easier to install compared to other types of boilers.
  • This system boiler responds quickly to your hot water demand, because of a built-in pump.
  • You can use more showers at the same time, without losing any power in the shower.

The great performer system boiler has a few disadvantages:

  • We need to install one hot water cylinder, and this can take up a little more space.
  • You have to use a storage cylinder in the airing cupboard.
  • Your hot water capacity depends on the tank size! If you have used all of your hot water, you have to wait till the boiler reheats the cylinder.
  • Without pipe insulation, you will have some heat loss on the pipes!

Also called a conventional, traditional or regular gas boiler. This is the oldest boiler system in the UK, and some places are still working fine.
The regular boiler is ideal for more than one bathroom. Where the water pressure is low and there is a high demand for hot water it’s the perfect choice.
We upgraded this regular boiler with a system or combination boiler. We supply and install these boilers, where the old regular boiler has broken down.

You have three installation options which you can choose:

  • We can install the same regular boiler.
  • We can install a system boiler by removing the F&E tank from the attic.
  • We can convert your conventional system to a sealed system. For system conversion, we install a combi boiler.

This boiler also has one hot water storage tank, where the hot water is stored and heated. These boilers also have a water tank in the attic. This tank will supply the water for the cylinder.

  • There is a separate F&E tank in the loft. This will top up the heating system through a feed pipe when needed. For a conventional system, a regular boiler is a perfect option.
  • It is because there is low pressure, and the radiators and heating pipes are old. The weak system can not resist the high pressure that a system or a combi boiler will deliver.

Conventional boiler advantages:

  • You have water backup. In case of a boiler breakdown, you can use the electric immersion heater.
  • You can use more showers at the same time without any effect on the pressure or temperature.
  • Any new regular boiler can work with an old system.
  • The regular boiler is also compatible with solar thermal panels.

The conventional boiler has a few disadvantages:

  • This takes up a little more space than other boilers.
  • We need to keep the old cold water tank in the loft to feed the storage tank.
  • If you have used all of your hot water from the storage tank, you will have to wait 30 minutes for the boiler to heat up the cylinder.
  • To avoid the legionella bacteria from growing inside the tank, make sure you always heat the tank above 60°C.
