If you’re considering a new boiler for your home in Leamington Spa, Warwick, or anywhere across Warwickshire, one of the first questions on your mind is probably: how long is this going to take? The good news is that most boiler installations are completed within a single working day — though a few factors can affect this.
Typical Boiler Installation Time
For a like-for-like boiler replacement — where the new boiler goes in the same position as the old one — you’re usually looking at 4 to 6 hours. Most engineers from PPS Gas & Electric will be in and out within a full working day, leaving you with a fully functional heating system by evening.
What Can Make the Job Take Longer?
Not all installations are straightforward. Here are the main factors that can add time to the job:
- Changing boiler position: Moving a boiler from the kitchen to the airing cupboard, for example, means more pipework and time.
- Switching boiler type: Converting from a heat-only (regular) boiler to a combi, or vice versa, involves more work to the system.
- First-time installation: If you’re fitting central heating where there was none before, the job will take significantly longer — potentially 2–5 days.
- Older property challenges: Older homes in Warwickshire can sometimes present unexpected plumbing challenges.
- System condition: If the existing pipework or radiators need attention, this will add time.
What Happens on Installation Day?
Here’s a typical breakdown of what your engineer will do:
Morning
- Drain down and remove the old boiler
- Prepare the pipework and flue connection
- Mount the new boiler and make pipe connections
Afternoon
- Connect the gas supply and electrical controls
- Fit the flue through the wall and test for sealing
- Refill and pressurise the system
- Commission the boiler and run a full test
- Walk you through the controls and programmer
Do You Need to Be at Home?
Yes — someone over 18 needs to be present for the duration of the installation. Your engineer will need access to the property, and at the end they’ll need to hand over the boiler controls and paperwork with you.
What About Disruption to Hot Water and Heating?
You’ll have no hot water or central heating during the installation, so plan ahead — especially if you have young children or vulnerable family members. Most installations are completed in a single day, so disruption is kept to a minimum.
After the Installation
Once the boiler is installed, your engineer will register the boiler with the manufacturer on your behalf (if included in the package) and issue you with a Building Regulations compliance certificate (Part P/Part J). Make sure you receive these documents — you’ll need them if you ever sell your home.
