What a boiler swap usually looks like in Croydon.
Croydon's stock spreads fairly evenly across types. Census 2021 puts 29 per cent of homes in purpose-built blocks of flats, 25 per cent semi-detached, 23 per cent terraced, 12 per cent detached and 9 per cent in converted houses. The Victorian and Edwardian terraces run through Addiscombe, South Norwood, Thornton Heath and Broad Green, the inter-war semis and detached houses fill Shirley, Selsdon, Sanderstead, Purley and Coulsdon, and New Addington is a large post-war council estate on the eastern edge. The town centre has seen former office towers converted to flats in the last decade.
In the terraces of Addiscombe and Thornton Heath the boiler usually sits in a rear kitchen or a back-addition bathroom, and a combi swap with a rear-wall flue is the normal job, though an older open-vented system with a cylinder still turns up and the mains pressure decides whether a combi conversion will work. The larger semis and detached houses of Sanderstead, Purley and Coulsdon often have two bathrooms and loft conversions, which is where a system boiler with an unvented cylinder tends to be specified rather than a combi. Census 2021 shows 75 per cent of Croydon households on mains gas only and 10 per cent electric only, the latter mostly in the flats around the centre, where converted office buildings often have no gas at all.
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 Croydon
Our engineers cover CR0, CR2, CR5, CR7, CR8, SE19, SE25 and the wider Greater London 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 Croydon will not mind being asked, and one who bristles has told you something useful.
Water and heating in Croydon
Croydon is split between two suppliers. Thames Water serves the centre and north, including Addiscombe, Thornton Heath and the Norwoods, and SES Water serves the south from South Croydon down through Purley and Coulsdon. Both draw on chalk groundwater and both are hard, with published readings for the borough in the region of 250 to 300 mg/l as calcium carbonate, so scale protection on the hot water side is needed whichever company bills you.
Planning, flats and the edges of Croydon
Croydon has 22 conservation areas, among them Central Croydon, Church Street, Croydon Minster, The Waldrons, Chatsworth Road, Addington Village, Norwood Grove, Beulah Hill, Upper Norwood Triangle, South Norwood, and the Norbury Estate, an early London County Council cottage estate. In those streets a flue on a front elevation may need planning consent as well as building regulations sign-off. The town centre and Wellesley Road have some of the tallest residential buildings in outer London, where heating is often communal and an individual flat cannot simply have a new gas boiler fitted. Building control is Croydon Council, and gas here is distributed by SGN because the borough lies south of the Thames.
Areas of Croydon this covers
Addiscombe, South Norwood, Thornton Heath, Shirley, Selsdon, Sanderstead, Purley, Coulsdon, New Addington and Upper Norwood, and everywhere else in CR0, CR2, CR5, CR7, CR8, SE19, SE25. The districts are Croydon itself; a job just outside them still reaches engineers who cover that postcode.
Croydon questions.
Is Croydon's water hard, and which water company do I have?
Both companies serving Croydon supply hard water. Thames Water covers the centre and north of the borough, including Addiscombe, Thornton Heath, Selhurst and the Norwoods, while SES Water covers South Croydon, Purley, Sanderstead and Coulsdon. Each draws largely on chalk boreholes and published figures for the borough sit around 250 to 300 mg/l as calcium carbonate. At that level limescale builds on a combi's plate heat exchanger and in hot water pipework, so most boiler makers ask for a scale reducer or inline inhibitor on the cold main, and some make it a condition of the warranty.
My 1930s semi in Shirley has a hot water cylinder. Should the new boiler be a combi or a system boiler?
It depends on how many bathrooms are in use at once and how strong the incoming main is. Many inter-war semis in Shirley, Selsdon and Sanderstead still run an open-vented boiler with a cylinder in the airing cupboard and a tank in the loft, and where there is one bathroom and good mains pressure a combi conversion frees that space. Where the house has been extended into the loft and has two showers, a system boiler with an unvented cylinder keeps pressure steady in both. An engineer will measure flow and pressure at the kitchen tap before recommending either.
What does a new boiler cost in Croydon?
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 Croydon do you cover?
Croydon is CR0, CR2, CR5, CR7, CR8, SE19, SE25, and we match on the outward code, so a job in CR0 only goes to engineers who have told us they cover CR0. 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 Croydon?
Your job reaches engineers covering CR 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 Croydon 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 Croydon?
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.
