Whether your old boiler’s on its last legs or you’re upgrading to something more efficient, getting a new boiler fitted can feel like a big job, especially if you’ve never done it before. But it doesn’t have to be stressful.
At Clyde Boiler Installations, we’ve been fitting boilers across Glasgow for years, from traditional tenement flats in Shawlands to new-builds in Bearsden. This guide walks you through the full boiler fitting journey so you know exactly what to expect, how to prepare, and how we make the process simple, safe, and efficient.
Step 1: The Boiler Fitting Survey
Every boiler fitting begins with a free, no-obligation home survey. One of our Gas Safe registered engineers will visit your home to:
- Inspect your current boiler setup
- Check pipework, radiators, and flue positions
- Assess water pressure and heating needs
- Flag any access issues (common in older Glasgow flats)
Local tip
In properties like Victorian tenements or converted lofts, we often plan for non-standard layouts and legacy systems. That’s why our surveys are detailed and tailored to each home.
After the visit, we’ll send you a fixed-price quote. No hidden fees. No surprises.
Step 2: Choosing the Right Boiler for Your Glasgow Property
Once the survey is complete, we’ll help you choose a boiler that suits your home and lifestyle.
In Glasgow, combi boilers are ideal for flats and smaller properties as they save space and provide hot water on demand. For larger homes or households with multiple bathrooms, a system or regular boiler may be more appropriate.
What we consider
- Your home’s layout and age
- Number of bathrooms
- Existing pipework and radiator compatibility
- Local water pressure
- Budget and efficiency goals
Glasgow-specific insight
In areas like Hyndland or Pollokshields, older pipework may need slight updates to support a modern boiler. We’ll flag this early in the process.
Step 3: Preparing for Your Boiler Fitting Day
To keep the fitting process smooth, a little prep goes a long way. Here’s what we recommend:
- Clear the space around your current boiler
- Make sure someone is home during the time slot
- Let us know about pets or access instructions
- If parking is limited, try to reserve a nearby space
What we bring
We’ll handle the rest. From dust sheets and floor protection to tools and materials, our team comes fully equipped and respectful of your home.
Step 4: The Boiler Fitting Process
Here’s what typically happens on fitting day:
- Switch off and isolate the system
- Remove the existing boiler
- Fit the new boiler in the agreed location
- Connect flue, pipework, and condensate drainage
- Flush the system if needed
- Test and commission the new boiler
- Clean up and tidy the work area
Time estimate
A straight combi-to-combi boiler fitting usually takes one working day. More complex upgrades (like changing boiler types or relocating the unit) may take two to three days.
Note for older homes
Routing pipework in tenement flats or listed buildings may take longer, but we plan thoroughly so you’re never left in the dark.
Step 5: Final Checks, Certification, and Handover
Before we finish the job, we’ll make sure everything is working safely and efficiently. This includes:
- Issuing your Gas Safe certificate
- Completing the Benchmark logbook
- Registering your boiler warranty
- Explaining how to use the new controls and thermostat
You’ll also receive a handover pack with everything documented and saved.
Listed buildings or conservation areas
If your home is listed or falls within a conservation area, we’ll advise on flue positioning or permissions as needed.
Step 6: Aftercare and Ongoing Support
Even after your boiler is fitted, our job isn’t over.
We’ll remind you when your first annual service is due to keep your warranty valid and your system running smoothly.
If anything unexpected comes up, our Glasgow-based engineers are just a call away. Because we’re local, we can usually attend promptly.
