How Long Does it Take to Install a Boiler?

When you have an outdated or defective gas boiler, replacing the entire unit is often the only solution. Moreover, it’s not a job that can afford to wait as persisting with a faulty boiler can waste money and pose potential safety risks.

As well as providing increased cost-efficiency, new boilers will reduce your carbon footprint. So, how can you go about fitting a new boiler and how long does it take? Here’s all you need to know.

New boiler installation times

The short answer is that your new boiler installation will take between 1-2 days. There are several variables that will dictate how long it takes, such as the boiler size and complexity of a job. Replacing a combi boiler with a new combi boiler, for example, will only take a day. Changing an old system boiler to a combi will take longer.
This timeframe covers all aspects of the boiler install procedure, including;

  • The safe disconnection and removal of the old boiler
  • New boiler installation and all necessary safety tests
  • Cleaning any mess and disposing of the old boiler

Why should you use a professional?

It may be tempting to complete this job on a DIY basis, but only a certified Gas Safe registered engineer can install a boiler. This is because the new system must meet new safety regulations. Following the boiler install process, you will gain a certificate to confirm that yours meets the latest guidelines.

Unfortunately, if your gas pipes are old, they may need replacing as the regulations state that they must now be 22mm (the limit used to be 15mm). If your gas engineer needs to complete this assignment, the installation could take a day longer than expected.
