50 YEARS SERVING CHESTER-LE-STREET
Boiler Installation,
In Chester-le-Street
As a local boiler installer covering Chester-le-Street, we install gas and electric boilers across the town, including in its many family homes. We size systems for how the property is used today, rather than simply swapping the existing boiler like-for-like.
Our process is simple: a free home visit and quote, an installation date to suit you, and most jobs completed within a single day. Every boiler comes with a full manufacturer’s warranty and Gas Safe registration on completion.
BOILER UPGRADES
Boilers We Install And Upgrades Availables
We primarily install Worcester Bosch boilers and are long-standing Worcester Accredited Installers, offering warranties of up to 12 years. We’re also accredited installers for Baxi and Viessmann. Alongside combi boilers, we install system, traditional (regular), electric and LPG boilers, as well as unvented cylinder systems where they’re better suited to the property.

BOILER TYPES
Which Boiler Is Right for Your Home?
The right boiler depends on your property, not just your budget. As a rough guide:
Extended Or Converted A Loft
Often means extending radiators and system capacity rather than just replacing the boiler
Larger Family Or Higher Hot Water Demand
A system boiler with an unvented cylinder often works better than a combi
Like-For-Like Replacement
Usually a straightforward combi-to-combi swap if the property hasn’t changed

FAMILY HOMES & EXTENSIONS
Extending Your Heating System In Chester-le-Street
Chester-le-Street is home to a lot of family houses, and extensions, loft conversions and conservatories are some of the most common reasons a heating system needs more than a like-for-like boiler swap.
We regularly help homeowners extend central heating into new rooms, add or upsize radiators, and upgrade to a system boiler with an unvented cylinder where an additional bathroom or growing household has increased hot water demand.
DO YOU NEED A NEW BOILER?
Benefits Of A New Boiler
Replacing an older boiler isn’t just about fixing something that’s broken. A modern A-rated condensing boiler can reduce energy use, running costs and emissions compared with an older, inefficient system — potentially making a noticeable difference in a busy family home.
We’ll give you a straight comparison of running costs for your specific property during a free quote, rather than a generic estimate.
- Lower running costs, especially compared with an older, inefficient boiler
- Far fewer breakdowns and call-outs than an ageing system
- A full manufacturer's warranty for peace of mind
- Compatible with smart heating controls, for better day-to-day efficiency
- Lower carbon emissions than an old, inefficient boiler
AFFORDABLE SERVICING
Boiler Servicing
In Chester-le-Street
Regular servicing keeps your boiler safe, efficient, and within its warranty terms. Our Gas Safe engineers carry out a full service every visit — visual inspection, flue and ventilation checks, system pressure, condensate trap and filter, and more. We service all boiler brands, not just the ones we install.
Why annual servicing matters:
- Keeps your boiler running efficiently, which helps keep bills down
- Checks safety components, reducing the risk of leaks or faults
- Catches small issues before they become expensive breakdowns
- Keeps your manufacturer's warranty valid - most require an annual service
CP12 GAS SAFETY
Landlord Gas Safety Certificates In Chester-le-Street
If you’re a landlord, we also provide CP12 Gas Safety Certificates across Chester-le-Street. During the inspection, we’ll check all gas appliances, pipework and flues, ensuring your property meets current gas safety regulations and providing the documentation you need to stay compliant.
FREE EXTENDED WARRANTIES UP TO 12 YEARS
Boiler Repairs
In Chester-le-Street
With so much family housing across Chester-le-Street, we regularly repair older heating systems that have had extra radiators, extensions or other demands added over the years. Common faults include no heating, no hot water, low boiler pressure, a diverter valve fault, or radiators heating unevenly.
We repair all boiler brands, not just the ones we install — Alpha is one example we repair but don’t fit as new. Many repair call-outs can be attended the same day, depending on engineer availability.
HONEST RECOMMENDATIONS
Repair or Replace?
Not every fault means you need a new boiler. As a rough guide, a single fault on a boiler under 8–10 years old is often worth repairing. If breakdowns are becoming frequent, the boiler is approaching the end of its expected life, or a major repair would cost a significant proportion of a replacement, we’ll talk you through both options.

“Will and his team were helpful and pleasant to deal with throughout the replacement of aging boiler. There was a lot to get through in a single day, but they arrived promptly with a strong team and got through the work quickly and efficiently, leaving everything tidy and clean behind them”
“Alex and Kyle fitted a new boiler moving it to the loft. Lovely guys, polite and friendly. The quality of work is exceptional. Despite it being in the loft where it will not be seen the pipes are really neat. Have a look at the photos. Never use anybody else.
“Just had a boiler installed by Housewarmers to replace the one they installed 18 years ago, and serviced annually by them.
Great service from a super friendly team. Fast and efficient installation, all rubbish removed and house left clean and tidy.
We have recommended Housewarmers to a few of our friends and they haven’t been disappointed with the level of service."
“I have had Housewarmers servicing my boiler for the last 19 years. We were looking at getting a new bathroom makeover and decided to ask Will at Housewarmers to give me a quote. We had the new bathroom installed in 2 days, this was for new wall panels, radiator, thermostatic shower, shower cubicle, and flooring.
Excellent job by Alex and Kyle.”

Only if your hot water demand justifies it — typically larger families or homes with more than one bathroom. We’ll advise honestly during your survey rather than fit one as standard.
