A few examples when you might have a problem, and it is time to call professional help to avoid major damage!

1.Bottom of the radiator is cold?

  • This is most likely a sludge build-up in the bottom of the radiator, this easily can be fixed! Our engineers check this using a thermal imaging camera. The solution is a central heating system cleaning.

4. Boiler switch themselves off?boiler service in north london, call us and choose your boiler

For our engineers, this including in the weekly repairs list. It can happen every second or minute. The boiler can lockout if you have some safety issues inside, so it is always better to have a look!

Good news is, if you have an annual service every year, this can be avoided.

Reasons for the lockout are:

Problem with:


  • The thermostat.
  • The central heating pump.
  • Pressure loss in it, or there is low pressure.
  • A shut off valve is closed, not allowing water flowing into the boiler.

5.Noisy boilers?

  • We mean gurgling or banging noises. Most of the cases related to the central heating pump. If the air will build up in the pump, causing an airlock and the pump will be noisy but can be fixed very simply. Usually, our gas safe engineers can sort out by bleeding the air from the pump. Also, double-check everything.

6. Kettling noises?

  • Can you hear kettling noise coming out from it? If so, this must be sludge in the heating system. This sludge will block the heat exchanger inside, and the water will start to boiling. This is a kettling noise, mostly happens in hard water areas.
  • Our gas engineers will check if they can be cleaned out. Sometimes, the old part has to be replaced, and we will install a scale reducer.
  • MML Plumbing’s local, reliable and experienced gas safe professionals can identify the problem, and fix it. Do not wait, book your service on time.

Central Heating System

There are 3 types of central heating systems in the UK, and we can install 3 types of boiler.

1. Combi Boiler System

This is very popular and also the most energy-efficiency system.

These systems don’t require a hot water cylinder in the airing cupboard. This gas boiler heats the water only when you need it, which makes it very efficient.

It is also heating your radiators when you turn up the room thermostat.

Which means:

  • You save a lot of space and money on your bills.
  • We can install modern heating controls.
  • Your boiler is heating the water only when you need it.
  • The boiler fed by main supply, and you can have powerful pressure at the shower.
  • This is recommended to serve only 1 bathroom.

2. High-Pressure System

Our installer helps you choose the best option for you.

Our installer can say that the main advantages of this boiler are:

  • You can have a storage tank installed.
  • The cold water will be fed from the main, thus producing powerful hot water for the bathrooms.
  • You can have multiple bathrooms.
  • You can use more than one shower at the same time.

3. Conventional Boilers

In this scenario, we install a regular boiler for you together with a storage tank. Usually, we replace or upgrade these types.

This can heat the radiators and also the cold water what is stored in the storage tank. This is ideal for homes, where is for low pressure and high water demand.

The Conventional Boiler advantages:

  • Because you have an immersion heater in the storage tank, you have backup water. If your boiler will break down, the immersion heater can be used.
  • Multiple people can use the bathroom at the same time.
  • Works with low pressure.
