So you’ve decided to upgrade your heating system and get a new boiler. It’s an exciting step towards improved efficiency and reliability, but many of our Bath customers wonder exactly what happens during installation. Having completed thousands of Worcester Bosch boiler installations across Bath and the surrounding areas, we’ve refined our approach to make the day as smooth and stress-free as possible for you.
In this guide, we’ll explain exactly what to expect when our heating engineers arrive at your door to install your boiler, from initial preparations to the final system checks.
Before Boiler Installation Day
Before we dive into the installation day itself, it’s worth mentioning some preparation that happens beforehand:
- Our team will have already conducted a thorough survey of your property to ensure the correct boiler type and size have been selected
- You’ll have received a detailed quote and installation date
- Our Gas Safe registered engineers will have ordered all necessary parts and equipment
What Time Will We Arrive?
We typically arrive between 8-8:30am. We understand the importance of punctuality, so our Bath-based engineers always aim to arrive promptly within the agreed timeframe.
How Long Does Boiler Installation Take?
The duration depends on the complexity of the job:
- Like-for-like replacements: Usually completed within a day
- System changes (e.g., conventional to combi conversions): May take 2-3 days
- First-time installations: Typically take 2-3 days, depending on pipework requirements
We’ll always give you a realistic timeframe before we begin, so you know exactly what to expect.
Step-by-Step: Your Boiler Installation Day

Common Questions About Boiler Installation
Will I be without heating all day?
Yes, it is likely your heating and hot water will be unavailable during the installation. We try to minimise this inconvenience by working efficiently, and in most cases, you’ll have a fully functioning system by the end of the day.
Do I need to move furniture or clear space?
We appreciate if you can clear the immediate area around your existing boiler and provide reasonable access to the installation location. We’ll handle the rest, including protecting your furnishings.
What about waste removal?
We take care of everything – you won’t be left with packaging or your old boiler to dispose of.
