What a boiler swap usually looks like in Durham.
Census 2021 counted 18,428 households in the Durham built-up area: 46.5% semi-detached, 20.4% terraced, 19.3% detached, 11.2% in purpose-built flats and 1.2% in converted houses. The terraces are concentrated in the Victorian streets of Gilesgate, Claypath, Crossgate and the Viaduct area, much of it now student housing within the Durham City Conservation Area. Newton Hall to the north is a large private estate of 1960s and 1970s houses, and Belmont, Carrville, Framwellgate Moor and Pity Me are mainly post-war semis and bungalows.
The Victorian terraces near the centre are tall and narrow, often three storeys on the Viaduct side, so a boiler on the ground floor faces a long run to the top bathroom and the flue usually goes through the rear wall into a small yard or up through the roof. Where a house has been converted to rooms for students, the boiler and cylinder sizing needs to reflect five or six people showering in the same hour, which favours a system boiler with an unvented cylinder over a combi. Newton Hall houses were built with gas from new and mostly run combis today, so the typical job is a straight swap.
We deliberately don't put a figure on this page, because nobody can price a boiler from a postcode. The cost calculator will give you a realistic range for a property like yours in under a minute, and three quotes for your actual job give you the real answer.
Getting three quotes matters more on a conversion
On a straight replacement the prices tend to cluster. On a cylinder-to-combi conversion they do not: how the engineer plans to route the pipework, whether a system flush is included and what happens to the cupboard afterwards can each move the number by hundreds. Three quotes is not about haggling. It is about seeing three different opinions on how the work should be done.
Whoever you go with must be Gas Safe registered. It is against the law for anyone else to work on your gas boiler, and you can check any engineer's registration number yourself before they start.
Finding a boiler engineer in Durham
Our engineers cover DH1, DH6, DH7 and the wider County Durham area, and those codes are examples rather than a limit. Rather than ringing round yourself, you fill in one form and we pass it to up to three Gas Safe registered engineers who work in your postcode. They contact you, they quote, and you decide.
Ask all three the same questions
Is the price fixed or an estimate? Does it include a power flush or just a chemical clean? Is a magnetic filter included, since most manufacturer warranties require one? Who notifies building control? A good engineer in Durham will not mind being asked, and one who bristles has told you something useful.
Water and heating in Durham
Postcode summaries built from Northumbrian Water's published data give DH1 an average of about 144 mg/l of calcium carbonate, which sits in the slightly hard band on the Drinking Water Inspectorate scale, a step up from the softer supplies in Newcastle and Sunderland. Northumbrian Water blends sources so the figure moves during the year. Limescale will form slowly in a combi's heat exchanger; a scale reducer is not required below 200 mg/l but is a cheap precaution here.
Planning, flats and the edges of Durham
Durham County Council provides building control for the city. The Durham City Conservation Area covers about 121 hectares, following the old borough boundary and taking in Crossgate, Gilesgate, Claypath and the Viaduct as well as the cathedral and castle World Heritage Site on the peninsula. An Article 4 direction that came into force in August 2016 removes some permitted development rights inside the conservation area, so a flue terminal on a front or street-facing elevation there should be checked with the council's conservation team first.
Areas of Durham this covers
Gilesgate, Claypath, Crossgate, Neville's Cross, Framwellgate Moor, Newton Hall, Belmont, Carrville, Pity Me and Langley Moor, and everywhere else in DH1, DH6, DH7. The districts are Durham itself; a job just outside them still reaches engineers who cover that postcode.

Durham questions.
My terrace in Gilesgate is in the Durham City Conservation Area. Does that stop me moving the boiler?
No, but it limits where the flue can come out. The conservation area and the 2016 Article 4 direction mean the council takes a close interest in anything that alters the street-facing side of the house, and a flue terminal on the front elevation may need consent. A rear kitchen wall or a vertical flue through the roof at the back avoids the issue in most Gilesgate and Claypath terraces. Inside the house the boiler can be moved freely, as long as the condensate has somewhere to drain.
Is water in Durham hard enough to bother with a scale reducer on a new combi?
It is on the borderline. Published figures for DH1 put the supply around 144 mg/l of calcium carbonate, which is slightly hard rather than hard, and below the 200 mg/l level at which Building Regulations expect scale protection on a combi. A small inline scale reducer on the cold main is still a sensible addition because a combi's plate heat exchanger is the first place limescale settles, and it is easier to fit at installation than later.
What does a new boiler cost in Durham?
It depends far more on the job than the town. A straight combi-for-combi swap sits at the bottom of the range; a cylinder-to-combi conversion sits well above it, and only an engineer standing in your house can see which one you have. The cost calculator gives you a realistic range in under a minute, and comparing 3 quotes for your actual job gives you the real answer.
Which postcodes in Durham do you cover?
Durham is DH1, DH6, DH7, and we match on the outward code, so a job in DH1 only goes to engineers who have told us they cover DH1. Those districts are the town itself rather than a service boundary. If your postcode isn't listed, enter it anyway: we place jobs across the UK, not only in the towns we have a page for.
How quickly can someone come out in Durham?
Your job reaches engineers covering DH and DL postcodes within about a minute of you submitting it. How soon one of them can actually fit a boiler depends on their diary and on the job, so we don't promise a date we don't control. If your boiler has failed completely, say so on the form and it is flagged as urgent.
Are your Durham engineers Gas Safe registered?
Yes. Every engineer on our network is on the Gas Safe Register and we check the number against the public register before any job is sent to them. It is illegal for anyone else to work on your gas boiler. Ask to see their ID card and check it yourself at gassaferegister.co.uk before work starts.
Do you own the property in Durham?
This is the one thing we have to know before anything else. A boiler replacement is a permanent change to the property, so it has to be authorised by whoever owns it - which means we can only arrange quotes for the homeowner, or for someone acting on the owner's behalf. Landlords are welcome to use the form for a property they let. If you answer no, we stop there rather than pass your details to an engineer who would not be able to take the job.
