If you’ve googled boiler prices and ended up more confused than when you started… yeah, that’s normal. Half the numbers online assume a “perfect” installation that basically never exists in real homes around Bromley, Orpington and the rest of South East London.
I’m Stuart (Gas Safe), and I’m on the road most days between Orpington High Street, Bromley South, the A21/A232 run into Croydon, and the A20 corridor. This page is the straight version: what a new boiler cost tends to look like, what affects the price, and how to spot a quote that’s missing the important bits.
The honest problem is this: two houses can be on the same road in BR6 and still need completely different work. One has tidy pipework and a sensible flue route. The other has a boiler shoved in a corner, a condensate run that freezes every winter, and a gas supply that’s… let’s be polite… “optimistic”.
That’s why you’ll see quotes all over the place. And it’s also why the cheapest quote often turns into the most expensive job once the installer starts listing “extras”.
Small note before we get into numbers: I’m not trying to scare anyone into spending more. I’m trying to stop you spending twice.
SKR Plumbing & Heating isn’t a call centre or a chain. It’s me and the team, and we’re the ones who turn up, protect the floors, fit the kit, and test it properly.
I’ve done a lot of boiler work in and around BR, CR, DA and the edges into Kent — and you start to notice patterns. The “quick swap” in a modern house off a wide road near West Wickham is usually straightforward. The older places, tighter cupboards, awkward flue routes, and surprise pipe sizes you get around parts of Chislehurst, St Mary Cray, or the hilly runs heading toward Sevenoaks… those are where the price moves.
One recent call in BR6 sticks in my mind. The customer had “shopped around loads” (their words) and got a bargain quote. When the installer arrived, suddenly there was a list: new flue, upgraded condensate, magnetic filter, system clean… all “optional”, but somehow also “required”. We ended up doing it properly from the start and the customer said the same thing most people do: “I wish I’d just asked what was included in writing.”
Real-world lesson: boiler prices aren’t just a number — they’re a scope of work.These ranges are realistic for homes we work in around Orpington, Bromley, Croydon, Dartford and nearby areas. They assume a proper install: safe flue, correct gas sizing, correct condensate, commissioning, and paperwork. Not a “fit-and-run”.
Want to understand what’s behind those numbers? This page is useful: what’s included in a proper boiler installation.
A quick reality check: if someone quotes £1,200 all-in for a “new combi fitted”, ask exactly what’s included. Sometimes it’s a genuine deal. More often it’s missing safety work, system protection, or the boring-but-critical parts like decent flushing and commissioning.
Here’s what changes the cost most — not in a salesy way, just in a “this is what takes the time” way.
If the gas pipe feeding the boiler is undersized, your new boiler can’t run correctly. It might “work”, but it won’t run right. Sorting that can mean new pipework runs, floors up, careful routing, proper testing.
You’d be amazed how often I see flues that are borderline — not always dangerous, but not something I’m comfortable leaving. A correct flue setup is non-negotiable. It’s safety. It’s carbon monoxide risk. It’s also why some quotes jump when you compare them.
In winter, the “cheap” condensate run is the one that freezes. If you’ve ever had a boiler stop on a cold morning when the school run traffic is already stacking up near the A21, you know how fun that is. Doing condensate properly avoids repeat call-outs.
If a system is sludgy or neglected, installing a shiny new boiler onto it is like putting a new engine into a car with dirty oil and hoping for the best. You might get away with it. Or you might not. This is why you’ll see recommendations for a clean, inhibitor, and sometimes a filter.
If your boiler is still running but you’re unsure whether to replace or maintain it, this is a useful starting point: how a proper annual boiler service is done.
BR6 — replacement boiler, “nothing was too much trouble”. The customer had been quoted all sorts. We did a proper survey, explained what we’d include, and didn’t play the “it’ll be extra later” game. The install went smoothly and the feedback was basically: reliable, genuine, good value. That’s the aim every time.
(Paraphrased from a July BR6 review.)DA4 — multiple jobs over time. One household had a boiler service, radiators, and a gas oven installation done across different visits. What they appreciated wasn’t magic — it was turning up when we said, keeping it tidy, explaining what we were doing, and finishing properly. Consistency beats “cheap” long term.
(Paraphrased from an August DA4 review.)CR2 — Sunday call-out, kept informed, reasonable price. Not boiler pricing exactly, but it shows how we work: clear ETA, clear cost, no disappearing acts. That same approach carries into boiler installs — you should know what’s happening and why.
(Paraphrased from an August CR2 review.)One more trust thing: we’ve also had a low review in the past about delays and attendance on a bigger refurb. I’m not pretending it didn’t happen. Bigger projects can overrun if schedules go sideways — the lesson for us is to communicate earlier and tighter. For boiler installs specifically, we keep scope and timing clear so you’re not left guessing.

When people compare boiler quotes, they often compare a number… but not the scope. Here’s what we typically include (and you should expect from anyone quoting sensibly):
If you’re weighing up whether to replace or repair, this page can help with the decision: boiler repair vs replacement guidance.
I’d rather you read one good page and make the right decision than panic-buy a boiler because someone on the phone made it sound urgent.
(We’ll build dedicated “price-by-brand” pages too — but I’d rather publish them once they’re genuinely useful, not just placeholders.)
Usually it’s not the boiler — it’s the setup. Gas pipe sizing, flue condition, condensate route, access, and whether the installer is including the safety/commissioning properly. Two “combi swaps” can be totally different once you check what’s behind the casing and where everything runs.
Yes. If the boiler is generally healthy and the repair is sensible (and not a constant cycle), I’ll say so. A lot of breakdown calls we attend are small issues that are fixable. If the heat exchanger is done or you’re repeatedly chasing faults, then replacement starts making sense.
Sometimes they’re a base price for a best-case install. The problem is most homes aren’t best case. If your quote doesn’t mention flue work, condensate, system protection, or commissioning, it may be missing the stuff that stops headaches later.
System condition. If the water is dirty and you fit a new boiler without addressing it, you can shorten the life of the new appliance. It’s not glamorous work, but it’s the difference between “new boiler feels brilliant” and “why is it already noisy?”
A straightforward swap can often be done in a day. Conversions, relocations, or situations where pipework needs upgrading can take longer. If you tell me the boiler make/model and send a photo of where it sits, I can usually give you a realistic timeline (and not the “yeah mate, tomorrow” promise that then turns into next week).
No scripts. No pushing you into a decision. Just a proper conversation and a clear idea of what your house is likely to need.
