The cost of replacing a gas boiler is between €2,000 and €3,000 including installation. The exact price will depend on the type of gas boiler you are installing and individual labour costs. It is recommended to replace your boiler after 15 years as its efficiency will begin to reduce, leading to higher energy costs. Servicing your gas boiler each year can help to extend its lifespan and maintain its efficiency.
The cost of replacing your gas or combi gas boiler is around €2,000 to €3,000.
There are several factors that will influence the final cost, such as:
The size of your home will dictate the size of boiler you need and thereby its cost.
Below, you'll find a comparison of the estimated price of a gas boiler based on its size:
Size of Home | Boiler Size | Estimated Price |
|---|---|---|
One to Two Bedrooms | 15–18 kW | €2,500 |
Two to Three Bedrooms | 18–24 kW | €2,800 |
Four to Five Bedrooms | 30 kW | €3,000 |

As we can see from the table above, for smaller homes and apartments, a 18kw gas boiler would be sufficient while for larger homes, it would be better to invest in a larger boiler bigger than 20kw.
Given the factors that influence the final cost, we recommend getting two or three separate quotes before making a final decision on the price you are going to pay. This way you can try and find the best price that suits your budget.

Is It Better to Service or Replace My Gas Boiler?
Given the cost of a new boiler, you might want to consider servicing your boiler, especially if it isn’t that old or only a couple of issues that could be fixed by bleeding your boiler. Servicing a gas boiler will cost roughly €130.
If you’re certain that your gas boiler is broken and needs replacement, you should definitely look into getting it done as soon as possible.
Getting a replacement can take a bit of time, however, so you should follow these steps to get it done in a straightforward way:
Details About Your Current Boiler Quotes Assessment Installation
1
Make sure you know what type of boiler you have and how long you’ve had it. This will help a gas boiler company or engineer understand your needs.
2
Shop around for different boiler quotes and find out how much it will cost to replace. In some instances, if you have boiler insurance or cover, you might be able to get a discount on the cost of a new boiler.
3
You’ll need to get an assessment from a gas registered engineer to get an idea of what you need and what your property may require when it comes to your heating. The engineer will usually be from the same company as your boiler cover.
4
Once you’ve decided on the quote, you will need to get it installed. This must be done by a Registered Gas Installer (RGI) as you cannot install your own boiler. After installations, your engineer will double-check to see if everything’s in good working order.

To know how efficient your gas boiler compare to others such as electric, condensing or biomass boilers, you first need to look at its energy efficiency rating.
You can find these labels on various energy appliances in your home. Here is what these labels mean:
An inefficient gas boiler will use more units of gas than necessary to heat your home and water.
Using Ireland's average gas usage for a three-bedroom house, the yearly gas cost is approximately €1,403 including VAT.
An inefficient gas boiler, therefore, costs you the following:
Gas boiler efficiency rating | Extra gas cost per year | Estimated time required to pay off a new boiler |
|---|---|---|
B rating - 86-90% | €55 | N/A |
C rating - 82-86% | €112 | 30 years |
D rating - 78-82% | €168 | 20 years |
E rating - 74-78% | €225 | 15 years |
F rating - 70-74% | €280 | 12 years |
G rating - under 70% | €420 | 8 years |
