If you’re considering a new boiler in Ascot or the surrounding areas, one of the first questions you might ask is how long the installation will take. After all, a boiler replacement is a big investment, and knowing what to expect can help you plan. At T S Gas, we aim to make the process smooth, efficient, and stress-free, ensuring minimal disruption to your home.

In this post, we’ll explain the factors that affect boiler installation times, outline typical timelines, and help you understand how to make the process as quick and straightforward as possible.

 

How Long Does a Boiler Installation Take?

In general, installing a new boiler takes between 1-3 days, depending on the complexity of the job and the type of installation. For example, replacing an old boiler with a modern, like-for-like system will be quicker than switching boiler types or relocating your boiler to a different part of the house.

To give you a clearer picture, here’s a breakdown of the most common scenarios and their typical timelines:

 

1. Like-for-Like Boiler Replacement

If you’re replacing your existing boiler with a new model of the same type (e.g., swapping a combi boiler for a new combi boiler), the installation is relatively straightforward. In this case, the process usually takes 1-2 days.

The heating engineer will:

  • Remove the old boiler.
  • Connect the new boiler to the existing pipework.
  • Test the new system to ensure everything is working correctly.

This is the quickest and least disruptive type of installation, particularly if your existing pipework is in good condition.

 

2. Switching Boiler Types

If you’re upgrading to a different type of boiler—such as replacing a conventional boiler with a combi boiler—the installation will take a little longer. Typically, this process takes 2-3 days because additional work is required, such as:

  • Removing the old boiler and hot water cylinder (if you have one).
  • Adjusting or upgrading pipework to suit the new system.
  • Installing the new boiler and ensuring all connections are secure.

Switching boiler types can be a great way to improve energy efficiency and free up space, but it does require more time and planning.

 

3. Moving the Boiler to a New Location

Sometimes, homeowners choose to move their boiler to a different part of the house—for example, from the kitchen to the loft or garage. While this can be a practical solution for saving space, it does add extra time to the installation process.

Moving a boiler typically takes 2-3 days because the heating engineer will need to:

  • Reroute the pipework and flue.
  • Install new connections.
  • Safely remove the old boiler and fit the new one in its new location.

 

Factors That Can Affect Installation Time

Several factors can influence how long it takes to fit a new boiler:

  1. The Age of Your Heating System – Older homes with outdated pipework or radiators may require upgrades, which can add time to the installation.
  2. Boiler Type – As mentioned earlier, switching boiler types takes longer than a like-for-like replacement.
  3. Access – If your boiler is in a hard-to-reach location, such as a loft or tight cupboard, this can slow down the process.
  4. Additional Work – If you need a power flush to clean out your heating system, new thermostats, or radiator replacements, this will extend the installation time.

 

How to Prepare for a Boiler Installation

To ensure a smooth installation, there are a few simple steps you can take to prepare:

  • Clear the Area – Make sure the area around your boiler is accessible and free from clutter.
  • Check for Parking Access – If your heating engineer needs to park a van nearby, ensure there’s space available.
  • Discuss Your Needs – Before the installation, discuss any concerns or specific requirements with your engineer to avoid delays.

At T S Gas, we always provide clear communication and planning to keep the process efficient and stress-free.
