Boiler installation in Paisley without the guesswork
If your boiler is on its way out, you want it replaced quickly and at the price you were quoted. CDM handles boiler installation in Paisley and across Renfrewshire, fitting new boilers with a minimum 5-year warranty as standard. All gas work is carried out by our own Gas Safe registered engineers, and every job starts with a free, fixed, written quote, so the figure you agree to is the figure you pay.
Most of the calls we get are about boilers that have either packed in completely or limp along with pressure drops and lukewarm radiators. We replace old and broken boilers with a system sized for the house, matched to your radiators and hot water use rather than whatever is easiest on the day. One in-house team handles the whole job from survey to commissioning. No subcontractors, ever.
It’s the same small family-run team on every job, and customers mention Gary, Craig and James by name in our Google reviews, where we hold 5.0 out of 5 across 37 reviews. If you’d rather not pay for a new boiler in one go, finance is available to spread the cost. And once you accept your quote we don’t hang about. A house with no heating can’t wait, so we book the installation in fast.

What our boiler installations include
Every installation starts with a survey, because the right boiler depends on the size of your home, how many bathrooms you have and how you actually use your hot water. We’ll recommend a boiler that suits the house rather than the one that’s easiest to sell, and the quote covers the whole job, including any pipework alterations the new boiler needs.
On the day, the engineers disconnect and remove your old boiler, fit and commission the new one, and test everything before signing it off. You get a walkthrough of the controls so you’re not left squinting at a manual, and we take all the old kit and packaging away with us.

Boiler installation questions
How long does it take to fit a new boiler?
A straightforward like-for-like swap is normally finished in a day. Moving the boiler to a different spot takes longer, and we’ll give you a clear timescale with your written quote.
What warranty comes with a new boiler?
Every boiler we install carries a minimum 5-year warranty. To keep it valid the boiler needs servicing once a year, and we can take care of that for you too.
How long does a boiler installation take?
Most straightforward swaps are quick jobs, and anything more involved gets scoped properly at the survey. Your fixed written quote sets out the timescale before anything is booked.
Can I spread the cost of a new boiler?
Yes, finance is available. We’ll explain the options when we give you your fixed written quote, and there’s no obligation either way.
Do you take the old boiler away?
We do. The old boiler is disconnected safely and removed along with any packaging and waste from the job, so you’re not left with a pile of rubbish to get rid of.
