Gas Boiler Servicing

Regular boiler servicing is vital to ensure that your boiler is running safely and efficiently. Poorly maintained or faulty boilers present a serious health risk to you and your family as they can cause fatal carbon monoxide poisoning.

How often should I arrange a service?

You should arrange to have a Gas boiler service at least once each year. Annual servicing will ensure your boiler is operating properly at all times. This allows expert engineers a chance to identify small and potential problems before they turn into larger issues. In turn this will help avoid the need for emergency breakdown services and ultimately save you money.

When Should I Arrange a Gas Boiler Service?

Most people choose to have their gas boiler serviced in winter as this is when it is used the most. However you may want to take this into account when booking your appointment. It may be worthwhile booking your service in advance of the busy period or in a different season, such as summer. This means you can avoid long waiting times due to busy engineers. Arranging a service for the summer will benefit you as it gives you more time to have any problems resolved before the cold weather sets in.

What do Gas engineers do during a boiler service?

  • Our engineer will inspect your boiler and controls to make sure they are operating safely.

  • The inspection will include checking your boiler for corrosion and leaks.

  • Your boiler casing will be removed to check the functioning of its main components.

  • A gas pressure check will ensure your boiler is operating at the correct gas pressure.

  • A flue test will ensure that no unsafe emissions are being released from your boiler.

  • Your boiler’s parts will be cleaned as required.

  • Your boiler’s casing will be put back on and properly sealed.

  • Our engineer will leave a checklist with you including all of the relevant information you need about the safety of your boiler.

Oil Boiler Servicing

At DMS Installations we offer a fully comprehensive oil boiler service for just £250.

Why the Efficiency of Your Oil Boiler has been reduced

There are many reasons why the efficiency of an oil fired boiler could be reduced. Here are a few:

Heat Exchanger

Heat ExchangTo maintain your boiler efficiency the heat exchanger must be kept clean. Excessive smoke and partially burnt fuel deposits can cause soot to form within the boiler heat exchanger. This will restrict the amount of heat that can be transferred into the heating system water. Therefore the cleaner the heat exchanger, the more efficient the boiler will be.r

Oil Nozzles

The oil nozzles can also contribute to reduced boiler efficiency. Oil nozzles regulate how much oil passes through the burner. The nozzles are consumable items that over time become worn down. This affects combustion and lowers boiler efficiency. If the oil nozzles are not replace, they could cause “sooting up” of the heat exchanger due to too much fuel passing through the burner.


Photocells are an important safety feature which detect whether the boiler has been lit. Over time photocells can become glazed over with deposits of dirt from the boiler. If a photocell is dirty it may not be able to detect the burner flame correctly and could cause the boiler to shut down randomly. Boilers frequently switching on and off will be less efficient than those running for longer periods.


Electrodes produce the spark to light the fuel, if they are worn or in poor condition the boiler may not light. Electrodes can become worn down over time. They also attract soot and deposits of dirt. If the electrodes do become worn or dirty this will cause inconvenience, inefficiency and increasing fuel cost.

What to Do if You Have Not Been Servicing Your Boiler Regularly

If our expert engineers determine that your oil boiler requires any additional labour or parts that are not covered in our full service we will inform you of this before we start any work. At DMS Installations we always ensure that our customers have agreed to the extra costs before commencing the project.

Why You Need Oil Boiler Servicing

The best way to ensure your oil fired boiler remains operating efficiently is to have it serviced regularly. By doing so you can reduce your fuel bills and save money on costly call-out fees for unexpected breakdowns. OFTEC recommends that oil fired appliances and equipment are serviced at least once a year or as recommended by the manufacturer.

“Outstanding service”

Contacted DMS Installations when my boiler packed in. Can not fault the service from start to finish and I'm amazed how quickly my problem was resolved. They sent an engineer out to my house straight away to give me quotes for a new boiler then within three days I now have a new combi boiler fitted!! Which means hot water and working radiators woo hoo!! Would recommend this company to anyone.
