Increase Energy Efficiency With A Boiler Replacement

Choosing to replace your boiler might be a necessary investment to make if your current boiler has suddenly stopped working. However, you may wish to replace your boiler for energy efficiency reasons. Newer boilers are far more energy efficient than older models, due to their upgraded technology that goes on behind the scenes. The way in which they are manufactured nowadays ensures they are burning fuels more effectively, meaning that less heat is lost.

Additionally, with mod cons like thermostats, smart controls and more, modern boilers are far better at cutting the costs of your energy bills. Our A-rated combi or back boilers run at an efficiency output of 92%, while boilers that are 10 years old or older, may only be running at an efficiency of around 72%, meaning that a newer boiler can save you money in the long run.

Save up to £95 a month on your energy bills with a new "A" rated boiler

Why Choose Us For A Replacement Boiler?

Gas Safe Registered

At NCSA, we understand how important gas safety is for our customers. The work we do with boilers and boiler replacements is accompanied by a responsibility for health and safety on all our installations. That’s why we’re proud to showcase our Gas Safe verification. What’s more,  we’ve provided the importance of a Gas Safe registered engineer for your property, to help convey this even further.


If your boiler is 10 years old or more, we would recommend that you get it replaced to increase the energy efficiency of your property. As well as this, your boiler may need replacing if it;

  • Is visibly leaking
  • Needs constant repairs
  • Has a strange smell
  • Is making odd noises
  • Has a yellow flame
  • Water temperature keeps changing
  • High energy bills

If you are not sure if your boiler needs replacing, simply get in touch with our team.

With correct maintenance and servicing, your boiler should last at least 10-15 years on average.

On average a boiler replacement can take around 1-3 days to install. However, this can depend on a few different factors. For example, it will be much quicker if the boiler is the same as the one being replaced. So, if you have a combi boiler and you’re replacing it with another combi, this will be quicker than if you are replacing a different system with a combi. This is due to the nature of the boiler and the system it is connected too.
