Got a deteriorating boiler, and considering a replacement?
No problem. This quick guide is going to help you understand whether you should ditch it or fix it!
Some boiler manufacturers offer as little as 2-years warranty, which I personally believe, isn’t a great indication of product quality.
On the flip side, a friend’s about to upgrade his boiler (it still works), and it’s 22 years old!
Like a car, a lot of how long your boiler is going to last, comes down to its quality, and how it’s looked after (more on that later).
The more important question is…
When the potential savings due to reduced energy consumption, outweigh the monthly cost of a new boiler that’s more energy efficient.
Or, when a boiler is out of warranty, and you’re faced with constant repair costs that span into the 100s of pounds.
Let’s start with the repair costs associated with an old boiler. Because unlike energy consumption, this isn’t a savings guestimate based on studies. It’s fact; it’s the money that your boiler is costing you every year.
If you have a major failure on your boiler within the warranty period, your manufacturer should honour that warranty, and replace the offending parts.
One boiler we like, is the Baxi 600 Combi. For 7-years, Baxi have got you covered. If you’re out of warranty, repairing your boiler (check out our guide to boiler repair costs here) is going to start costing you a tonne of cash.
A typical example would be a pump, around £250 to replace. But, pumps are robust. If that’s given up the ghost, there’s a good chance other parts are about to follow suit.
It’s unlikely you’ll find a boiler repair company offering a specific service that gives you an overview of the current state of your appliance. But, there’s no harm in asking your engineer next time you have a service.
You’ll want to get them to assess expensive components for wear and damage, to get an overview of the condition your boiler is in. That means parts such as the:
If your boiler…
I’d be leaning towards a replacement. Or, at the very least, be getting quotes for both replacement and repair, and making a decision with the facts in front of you.
Either way, you can get quotes for both repairs and replacement boilers from multiple heating engineers here.
The next thing a lot of homeowners don’t consider, is energy consumption.
Some old boilers might surprise you, in terms of how much energy they use.
The Energy Saving Trust estimates that savings of up to £305 per year can be gained from a new boiler. Given you can get boilers on finance for as little as £17 per month, you could:
Of course, this £305 saving is going to reduce dramatically if you’re not using a G-Rated boiler, or you live in a small property with lower energy bills.
Anyway, here’s the chart:
|Old boiler rating||Semi-detached||Detached||Detached bungalow||Mid terrace house||Mid floor flat|
|G ( < 70%)||£200||£305||£155||£175||£95|
Expect to pay upwards of £1,600. We’ve created a detailed guide to new boiler costs here.

As we’ve already mentioned, the life of your boiler is dependent on the care you give it. If these preventative measures haven’t been put in place in your current heating system, there’s a good chance your boiler is suffering.
Prevention is better than cure, and an annual service from a Gas Safe engineer is going to help spot potential problems, before they develop into real problems.
And, if you want to comply with the warranty terms and conditions from most boiler brands, you’ll need to get one anyway.

Over time, the water in your heating system gets dirty. It’s a mixture of minerals in water, as well as rust breaking from the inside of towel rails, your radiators, and even from the inside of copper pipe work.
Dosing your heating system will break down these particles, ready for them to be removed from the system.
We’ve created a guide to central heating inhibitor here.
Now the particles are broken down into manageable chunks, they can be caught by a magnetic system filter. We’ve created a guide to exactly what they do, and which are the best brands here.
Most boiler installers will fit a magnetic boiler filter as standard.
And, if you know you’re in a hard water area, consider a limescale reducing filter. This focuses on removing limescale from the heating system.
