How Long Does a New Boiler Installation Take?

If you’re planning to replace your boiler, one of the first questions you’ll likely ask is: “How long will the installation take?” The short answer? It depends — on what’s being replaced, where it’s going, and whether any upgrades are needed.

How Long Does a Standard Boiler Replacement Take?

In most cases, a like-for-like boiler swap takes 1 day.

This includes removing the old boiler, installing the new one, updating the pipework as needed, setting up your thermostat, testing the system, and giving you a full handover.

What Can Add Time to a Boiler Installation?

Here are common factors that can stretch your boiler installation to 2 or even 3 days:

• System type conversion — e.g. changing from system boiler to combi
• New boiler location — moving it to a different room or wall
• Upgrading pipework — especially if existing pipes are undersized or old
• New flue setup — flue relocation or vertical flues
• Extra radiators or smart controls being installed at the same time

Same-Day Boiler Installations: Are They Possible?

Yes — if you’re replacing a combi boiler with another combi, in the same location and with minimal changes, we can often complete the job in one full working day. This is typical for customers choosing our Essentials or Plus boiler packages.

Boiler Upgrades That Take Longer

Here’s what might take 2+ days:

• Changing from a regular or system boiler to a combi
• Adding a magnetic filter, flushing radiators, or fitting new controls
• Carrying out a power flush on a sludged system
• Installing the boiler in a new location (especially with long flue runs)

We’ll always let you know upfront how long the job will take based on your home, system layout, and package chosen.

Can I Use Heating and Hot Water During the Install?

In most cases, you’ll be without heating and hot water for one day. If it’s a longer job, we’ll always keep you updated and may provide temporary heating if needed — especially in colder months.

How Can I Prepare for the Installation?

We recommend:

• Clearing access to the boiler and surrounding space
• Making sure pets and valuables are out of the way
• Having someone home to run through the controls with you afterwards
