How Long Does it Take to Fit a New Boiler?
On average most simple combi swap boiler installations take less than a day, however this may vary depending on your current system.
A broken boiler can be incredibly inconvenient, especially in the winter months when it is cold and you’re left with no heating or hot water until an engineer can come out to replace it.
For some unknown reason, boilers always seem to know when you’re at your busiest and decide to break at that exact moment, which is why we understand the pressure to get the job done as quickly as possible to get your heating up and running again without taking too much time out of your busy life.
The time it takes to fit a new boiler can vary, depending on factors such as the type of boiler you currently have, if you’re swapping to a different type, if you wish to relocate your boiler and if any additional work needs to be done e.g. fitting all new pipes.
In this guide, we’ll take a look at how these factors can affect the time it takes to install a new boiler and the costs that come with it, but first let’s look at what a general boiler installation involves.
What Does a Boiler Installation Involve?
- Arranging the Installation
To arrange an installation with iHeat, simply answer a few questions about your home and then select the boiler of your choice from a range that we believe to be most suitable based on your answers. You can then use our finance calculator to work out how you’ll be paying and choose a date for installation.
Once you have booked your installation, we will ask you to send us some images of your current boiler to send to the installer so they can prepare ahead. We will also give you a call 1-2 working days before the install to confirm your order and the engineer that will be installing your boiler. - Removing the Old Boiler
When the installer arrives at your property between, they will display their Gas Safety Registered ID card to confirm their identity and will update you on their progress as they follow a checklist to ensure each task is completed to a high standard. This begins with removing your old boiler.
- Installing the New Boiler
Once the old boiler has been removed, the engineer will start to install the new boiler in the same location, unless you have chosen to have it relocated, and a new iHeat thermostat. They will then fully test the new boiler and ensure the central heating system is fully balanced. - Any Mess Tidied and Old Boiler Disposed Of
The installer will tidy any mess and remove all packaging from your new boiler, as well as disposing the old boiler to ensure your home is left clean and tidy. A few days after the install we will call to check how everything went and if we could have done anything better.
How Long Does it Take to Install a New Combi Boiler
4-6 Hours
Replacing an old combi boiler with a new combi boiler in the same location is the simplest and quickest job for an installer to do. Assuming everything goes smoothly, this will usually take an installer a day’s work (4-6 hours).
During this time, the engineer will remove the old boiler, install the new one and give it a free chemical flush (not to be confused with a ‘power flush’) and fit an iHeat thermostat. Once the job is done, they will tidy and mess and dispose of the old boiler as well as the new boiler’s packaging.

How Long Does it Take to Replace a Regular/System Boiler with a New Combi Boiler?
Up to 2 Days
If you currently have a regular or system boiler and are looking to convert to a combi boiler, you should expect this to take longer than a like-for-like swap due to the extra work required, including removing the water tank that will no longer be required and any new pipework.
The installers must also gain access to the heating system which may mean that floorboards have to be lifted and any corrective work must be done afterwards.

How Long Does it Take to Replace a Back Boiler with a New Combi Boiler
Up to 2 Days
If you currently have a back boiler and are looking to convert to a combi boiler, you should expect this to take up to two days due to all of the extra work required. First of all, you will need your boiler relocated to a different place in the house.
This could be inside a kitchen cupboard, in an airing cupboard, utility room etc…
Secondly, all boilers need a flue or some way to ventilate harmful gases such as carbon monoxide. Back boilers vent these gases directly up a chimney, whereas a combi boiler can vent in both horizontal and vertical directions.
This means that you’ll need a new regular flue from the new location of the boiler.
All of the work such as the removal of the back boiler, the relocation of the new combi and any repiping and flue work that must be done is why the price of a back boiler replacement is much higher than a like-for-like combi swap.

How Long Does it Take to Relocate My Boiler?
+ Half a Day
There are a number of reasons why someone may wish to have their boiler moved from one position to another. For example, many homeowners feel that a boiler in their kitchen cupboard takes up too much space that could otherwise be used for storage.
In these cases, they may wish to have their boiler moved from their kitchen to the loft or an airing cupboard.
Due to the extra work involved in moving your boiler, such as repiping and installing a new flue, this can take around half a day on top of the time it costs to remove your old boiler and install the new one.
The further away from the original position you choose to move the boiler, the more complicated the job and therefore the longer it takes. The price of the job works in the same way.
| Boiler Type | Relocation | iHeat Cost |
|---|---|---|
| New Combi | Same Room | £250 |
| New Combi | Garage | £400 |
| New Combi | Kitchen | £400 |
| New Combi | Loft/Attic | £400 |
| New Combi | Utility Room | £400 |
| New Combi | Airing Cupboard | £400 |
| New Combi | Bedroom | £400 |

Other Factors that Affect How Long it Takes to Install a New Boiler
Your Current Heating System Doesn't Meet Gas Safety Regulations
Unfortunately, in England and Wales there are over 60 deaths from carbon monoxide poisoning every year. As a result, the government set up the Gas Safe Regulations which are there to prevent mistakes that could potentially result in a fatality.
One of the regulations that came into force within the last 15 years was the 22mm gas supply pipe rule. In the past, gas supply pipes had to be a minimum of 15mm, however this has since changed to 22mm.
Despite it being a legal requirement, many homeowners are unaware of this rule, so those who have boilers over 15 years old will likely have non-regulation pipes.
If an installer comes across 15mm pipes when installing the new boiler, they must legally replace your gas supply pipes with 22mm ones. This of course costs time and money, but it is a necessary part of the job.
Installing a Smart Thermostat
A smart thermostat has many benefits, such as giving you the ability to control your heating from anywhere and saving on your energy bills.
As standard, iHeat installs a free wireless controller, but we do offer the option of purchasing a smart thermostat which we can install and explain to you. Whilst it doesn’t take too long, it does add on a small amount of time to your installation, as well as the added cost of the thermostat itself.
