Gas boiler installation and replacement

A new boiler is a big decision. We size it properly, fit it neatly and certify it correctly, so you get reliable heat and hot water for years to come.

Whether your old boiler has finally given up or you are upgrading to something more efficient, a boiler is only as good as the installation behind it. We take the time to recommend the right unit for your home and the way you use it, rather than simply fitting the cheapest box on the shelf.

As Gas Safe registered engineers, we install and certify every boiler to the required standards. We work with trusted brands including Worcester Bosch, Baxi and Vaillant, and we will always talk you through the options and the warranty before you commit.

Why choose Sabin & Ball

We are not a rip-it-out-and-run outfit. Because we book work in properly rather than chasing emergencies, we can give your installation the care it deserves and leave your home clean.

We work across Leamington Spa, Warwick, Kenilworth, Stratford-upon-Avon, Southam and the surrounding Warwickshire villages. If you are just outside that area, ask and we will let you know honestly whether we can help.

Common questions

Which boiler brands do you install?

We regularly fit Worcester Bosch, Baxi and Vaillant, and can advise on the best option for your home and budget. Each comes with its own manufacturer warranty, which we will explain before you decide.

How long does a boiler swap take?

A straightforward replacement is usually completed in a day. A more involved job, such as moving the boiler or converting the system, may take longer. We will give you a realistic timescale with your quote.

Do you provide a Gas Safe certificate?

Yes. Every gas boiler we install is commissioned and certified by a Gas Safe registered engineer, and we notify building control where required.

What customers say

★★★★★
“Dan, Kyle and Albie replaced and moved our boiler from a bedroom cupboard into the garage. Booked us in quick, great advice, and very tidy, efficient work by all of them. Couldn't fault their work and would highly recommend.”

★★★★★
“Our family home required a new boiler, which Kyle and the team fitted on time, within budget and with minimal fuss. They turned up on time, tidied up after themselves and solved some very challenging problems in a tight boiler cupboard with minimal disruption. They are now our go-to plumbers for all jobs.”
