Additional Costs to Consider

Often it is not as simple as installing a new boiler, hitting the on button and forgetting about it. Depending on the existing system you have in place and how old it is, a competent installer may well recommend extra work to ensure your new heating system works to its full capacity.

This may include some of the following services:

  • Moving the location of the boiler
  • Removing old equipment, e.g. storage cylinders or water tanks
  • Adding or replacing radiators
  • Mechanical / chemical flushing of pipework (recommended)
  • Installing thermostatic radiator valves (TRVs)
  • New thermostats and smart programmers
  • Ongoing annual aftercare / servicing plan

Make sure you ask for an itemised quote from your installer as prices for these services can vary considerably between installers. You can then ensure you are comparing like for like and make sure you’re getting both a quality service and a competitive deal.

How Much Could a New Boiler Save You?

When faced with a substantial upfront cost like a new boiler it’s important to consider the long term benefits. The main benefits in this case being improved energy efficiency which will deliver both lower energy bills and reduced carbon emissions. The efficiency of a boiler represents the money you are wasting on lost energy. For example, if your boiler is only 70% efficient, you are losing 30p of every £1 you spend on your energy bills to wasted energy.

By installing a new A-rated, gas condensing boiler with a programmer, thermostat and TRVs in place of an older boiler with a programmer and thermostat, you should be able to achieve efficiency of 90% or higher. To illustrate what this means in the long term, you could make the following annual savings on your energy bills:

Old boiler efficiency rating Flat (mid-floor) Mid-terrace house Semi-detached house Detached house
78-82% D £55 £100 £110 £170
74-78% E £60 £105 £125 £190
70-74% F £70 £125 £145 £220
<70% G £100 £180 £210 £320
Average annual saving £71.25 £127.50 £147.50 £225
These figures have been taken from the latest research by the Energy Saving Trust using fuel prices in April 2017. Savings will vary depending on the size and thermal performance of your home.

Yearly Savings Conclusion: Installing a new A grade boiler could save you, on average, between £71.25 and £225 on your annual heating bill but savings could be as high as £320.
