New Town Estates
Post-war semis and terraces across the town often have heating systems that have been altered more than once. The boiler may be fairly modern while the pipework and radiators behind it are not.
Up to 18 years' warranty on ATAG boilers
12 years as standard, extendable to 18. Only approved installers can offer it, and we're one of the few in the North East who can.

A Boiler Firm on Peterlee's Doorstep
Our office and stores are at Castle Eden, TS27 4SU, a few minutes down the road from Peterlee. That matters more than it sounds. Surveys get booked quickly, the van is never far away if something needs checking after the install, and you are not waiting on a firm travelling in from another county.
Connected Gas & Heating has been trading since 1999 and has looked after more than 3,000 customers across County Durham. We complete over 150 boiler installations a year. Neil, the owner, still attends jobs himself, so the person quoting the work is the person responsible for it.
Peterlee Housing
What We Find in Peterlee Homes
Peterlee was built as a new town from the late 1940s onward, so a lot of the housing shares a similar age and layout. That gives us a fair idea of what to expect before we arrive, but every quote still starts from the property in front of us.
Older Radiator Circuits
Fitting a new boiler onto a tired system without cleaning it first is how warranties get refused. We assess circulation and system condition before quoting and include a flush where it is needed.
Back Boiler Replacements
Some homes still have an old back boiler or a boiler in an awkward spot. Moving it usually means new pipework and a new flue route, which we price properly at survey rather than adding on later.
Combi Conversions
Swapping a tank and cylinder system for a combi frees up a cupboard, but it only works where mains pressure and flow will support it. We test that on the survey rather than assuming.
Soft Water Locally
Water across most of the area is soft, which is kind to boilers and means limescale is rarely the problem. Sludge and poor circulation in older systems usually are.
Landlords and Rentals
There is a fair amount of rented property in and around Peterlee. We handle installations for landlords and agents alongside the gas safety certificates that go with them.
- The survey comes first. We look at the radiators, the hot water demand and where the boiler can sensibly go before we put a price on anything.
- The price is fixed before we start. What we quote is what you pay, unless you ask us to change the job.
- Old boiler removed and taken away. That is part of the job, not a line added at the end.
Approved Boiler Brands
Baxi and ATAG Approved Installation
We are approved by both manufacturers, so the recommendation is based on what suits your house rather than the only brand we happen to be able to fit.
ATAG Approved Installer
ATAG boilers carry a 12-year warranty as standard, extendable to 18 years when the terms are met. Only approved firms can install them, and we deal with ATAG directly.
How the ATAG warranty works
Baxi Approved Installer
We have held Baxi Approved Installer status for more than 15 years, since the scheme began. Baxi boilers fitted by us come with a 5-year guarantee.
Our Baxi approved installer statusWhat It Costs
Fixed Prices, Agreed Before We Start
We do not publish a headline figure for a new boiler in Peterlee, because the honest answer depends on the house. What we do is survey it, explain the options and give you one price that does not move.
The quote covers the boiler, the flue, the controls, any work the existing system needs and removal of the old unit. If something turns up that changes the job, we tell you before we do it.
Flexible payment options are available, and a service plan can be arranged afterwards so the annual service that keeps the warranty valid never gets forgotten.

Horden and Blackhall
Mining-era terraces where heating systems have often been changed piecemeal over the years. A full system assessment matters before a new boiler goes on.

Common Questions
New Boilers in Peterlee, Questions Answered
Do you cover Peterlee?
Yes. We are based at Castle Eden, around ten minutes from Peterlee, and we work across SR8 and the surrounding East Durham villages every week.
How much does a new boiler cost in Peterlee?
It depends on the boiler, the property, where the flue goes and what the existing system needs. We survey the house, explain what we would recommend and give you a fixed price before anything is booked.
How long does the installation take?
A straightforward replacement is usually quicker than moving the boiler, converting the system or fitting a new cylinder. We explain the expected timescale after the survey.
Can you replace a back boiler?
Yes. Replacing a back boiler normally means new pipework and a new flue route, which we assess and price at the survey rather than adding on later.
What warranty do I get?
Baxi boilers fitted by Connected Gas & Heating come with a 5-year guarantee. ATAG boilers come with a 12-year warranty as standard, extendable to 18 years when the installation and servicing terms are met.
Do you take the old boiler away?
Yes. Removal and disposal of the old boiler is included in the agreed installation price.
