All work fully insured and guaranteed.

The housing decides the calls. The flats bring pressure and combi faults, and leaks that reach a neighbour within the hour. The terraces bring imperial copper that needs the right adaptor, pipe runs buried under original floors, and stopcocks painted solid.
Looking for a plumber in Peckham? Dulwich Plumber works right across SE15, from the streets around Peckham Rye up to the high street, and the same Gas Safe engineers handle everything from a dripping tap to a dead boiler. Weekday call-outs start at £100 + VAT for the first hour, there's no separate call-out fee on top, and after that first hour it's billed in 15-minute blocks rather than rounded up.
Call 020 8935 5206 or WhatsApp 07521 853 507 with your postcode, a photo of the problem and, for boiler faults, the make, model and any code on the display. You'll get a straight answer on timing and an estimate before work starts.

We cover Peckham SE15 from our Dulwich base, so getting here doesn't eat into the job. Send the postcode and a photo by WhatsApp and we'll say whether it's a job for today or one that can wait for the cheaper daytime rate. Fixed-price work (a boiler service or a landlord gas certificate) is quoted as an exact figure, never "around" or "roughly." A diagnosed fault works differently: it's priced once we know what's actually wrong, and that diagnostic time itself is charged at the standard hourly rate.
Most calls aren't boilers. Leaking pipes under a sink, a toilet that won't stop running, a shower that's gone from a trickle to nothing, a radiator that stays stone cold. That's the bulk of the work across SE15's mix of Victorian terraces, flat conversions and the newer blocks near the station.
Some of it comes down to what's actually behind the wall. Older SE15 terraces still often run on imperial copper or, occasionally, the original lead supply pipe, and a fix that takes minutes on modern plastic push-fit can mean working around a painted-over stopcock or tracing a pipe route under floorboards instead.
Send a photo by WhatsApp and we'll usually tell you what's involved before anyone gets in the van. A good few of these turn out to be a quick fix rather than a full replacement once we've had a proper look, which keeps the bill down. Every job is priced from the same published rate card; there's nothing extra for being in Peckham rather than Dulwich itself.
Boilers are the single biggest reason Peckham residents call us, and it's rarely the whole unit that's gone wrong. Usually one part has failed and the rest is fine.
Pressure that keeps dropping, a boiler that locks out and won't reset, hot water with no heating (or the other way round): these point at a handful of usual suspects, among them a diverter valve, a failed sensor, a worn pump, or a printed circuit board. We work on any make of gas boiler, no brand restrictions, and diagnosis happens before anything gets replaced. Fault-finding is charged at the standard hourly rate, because working out what's actually wrong is skilled time in its own right. If you've got a fault code on the display, send it with the make and model over WhatsApp before we arrive; it often tells us most of what we need to know.
A boiler service is £100 + VAT, fixed. That covers a visual check of the boiler, flue and its surroundings, the casing off to inspect the burner and heat exchanger, safety devices tested, and a flue-gas analyser reading to confirm it's burning cleanly. It's worth doing every 12 months, since most manufacturers make it a condition of the warranty, so skipping a year can leave a later claim exposed even on a boiler that's barely been used. Book it alongside a landlord gas safety certificate if you need both; they're two separate jobs, £100 + VAT each, so £200 + VAT for the pair with no discount for combining them, but only the one visit.
A straight like-for-like combi swap is normally a one-day job; changing the boiler type or moving its position runs to two or three days. There's no fixed installation price published, because every property is different. The process is a ballpark figure over the phone first, then a free on-site survey for anything over about £1,500, then a written quote before anything's ordered. As a rough steer, a full boiler swap tends to land somewhere around £3,000–£4,000 all-in including VAT, and a hot water cylinder replacement around £1,700–£2,000; the survey is what turns that into a real number for your flat or house.
We take emergency calls out of hours, though what we can reach depends on which engineer is free at the time. We'd rather say that plainly than promise something we can't back up. Out-of-hours work is priced by the same time-band system as everything else rather than a flat "emergency" surcharge: weekday evenings (6pm–midnight) £145 + VAT/hr, weekday overnight £180, weekend or bank holiday daytime £145, weekend evening £180, and weekend overnight £270, all with the first hour as the minimum and no call-out fee stacked on top.
If you can smell gas, don't call us first. Call the National Gas Emergency line on 0800 111 999, free, 24 hours. Don't touch light switches or plug sockets, don't light anything, open the windows and doors and get out of the property. Once the gas network has made things safe, that's where a Gas Safe engineer comes back in.
A burst pipe, water you can't stop, no heating in cold weather: turn the water off at the stopcock if you can reach it, and call 020 8935 5206.
£100 + VAT an hour on a weekday between 8am and 6pm, first hour as the minimum, then billed in 15-minute blocks of £25 + VAT rather than rounded up to the next full hour. No call-out fee, ever.
| When | Rate + VAT |
|---|---|
| Weekday 8am–6pm | £100/hr |
| Weekday evening 6pm–midnight | £145/hr |
| Weekday overnight midnight–8am | £180/hr |
| Weekend/bank holiday day | £145/hr |
| Weekend/bank holiday evening | £180/hr |
| Weekend/bank holiday overnight | £270/hr |
For anything likely to run past about six hours, a day rate usually works out cheaper: £680 + VAT weekdays, £870 + VAT weekends and bank holidays. It's the same figure everywhere we work, with no premium for Peckham over Dulwich itself. See the full rate card for every band. Payment is by card on completion; we take all major debit and credit cards except American Express, and we no longer take cash.
A power flush for a typical system up to ten radiators is priced as one day at the day rate above, plus roughly £40 for the cleaning chemicals and inhibitor. A magnetic filter, which stops that sludge building back up, is £230 + VAT supplied and fitted. It's worth having on most systems, and several manufacturers now require one for the extended warranty on a new boiler.
SE15 isn't one type of housing. Around Bellenden Road and Choumert Road it's mostly Victorian terraces, plenty still on their original pipe runs. Closer to Peckham Rye and the newer developments near the station it's flats and conversions, often with shared risers and pressurised combi systems. Both throw up different faults, and we've worked on both often enough to know what to check first.
A boiler that keeps losing pressure in one of the Rye-side conversions is a common one. Often it's not the boiler itself but a failed expansion vessel or a small leak somewhere in the system, both of which show up once you know where to look. In the older terraces further from the park, it's more often a stopcock that hasn't been turned in years and needs care rather than force, or original pipework that's finally worn through at a joint.

£100 + VAT on a weekday between 8am and 6pm, with the first hour as the minimum and 15-minute billing after that, no call-out fee on top. Evenings, overnights, weekends and bank holidays move up through the bands published on our rates page, up to £270 + VAT/hr for a weekend overnight. The same rates apply everywhere we cover; there's no extra charge for Peckham over Dulwich itself.
Yes: £680 + VAT for a weekday, £870 + VAT for a weekend or bank holiday. It usually makes sense once a job looks like it'll run past about six hours, a bathroom refit or a multi-radiator power flush being typical examples. One day rate covers the whole team, whatever the mix of trades needed.
The first hour, billed at the applicable rate: £100 + VAT on a weekday daytime. After that it's 15-minute blocks, so a job that finishes 20 minutes past the hour is charged the hour plus one block, instead of a second full hour.
We charge by time rather than a flat fee: £100 + VAT/hr weekday daytime, first hour minimum, parts extra. Most common faults (low pressure, a lockout, a failed diverter valve) are diagnosed inside that first hour. We work on any make of gas boiler.
Once a year. It keeps the manufacturer's warranty valid, catches small faults before they turn into a breakdown in the middle of winter, and doubles as a safety check on the flue and gas connections. A service is £100 + VAT, fixed.
Depends on the fault. A well-installed boiler typically runs 10–15 years or more, and a single failed component on a younger unit is usually worth fixing. When repairs keep coming back, or a major part like the heat exchanger fails on an older boiler, replacement tends to make more financial sense, and we'll tell you which side of that line yours sits on.
The same published bands as everything else, just at the out-of-hours rate: £145 + VAT/hr weekday evening, £180 overnight, £145 weekend day, £180 weekend evening, £270 weekend overnight, first hour minimum, no separate call-out charge. Whether we can reach you depends on which engineer is free at the time.
Water you can't stop, no water at all, sewage backing up, a leak anywhere near electrics, or no heating in genuinely cold weather with anyone vulnerable in the house. If you're not sure, call and describe it; we'll say whether it can safely wait for the cheaper daytime rate.
Don't call a plumber first. Call the National Gas Emergency line on 0800 111 999, free and available 24 hours. Don't touch switches or sockets, don't light anything, open windows and doors and get everyone out. Gas Safe work on the appliance afterwards is where we come back in.
£100 + VAT, covering up to two gas appliances, typically the boiler and a gas hob. Each extra appliance beyond that is £30 + VAT. A separate gas fire, where fitted, is priced as its own one-hour service rather than folded into the extra-appliance charge. Book it alongside a boiler service and it's two separate fixed prices, £200 + VAT total, done in one visit.
For most systems, yes. It catches the sludge circulating in the pipework before it reaches the boiler, protecting the pump and heat exchanger, and several manufacturers now make one a condition of the extended warranty on a new boiler. Supplied and fitted, it's £230 + VAT.
Yes: Gas Safe registration 657719, checkable at gassaferegister.co.uk, and the business carries £2,000,000 insurance. Every gas job in Peckham is carried out by a registered engineer, our work is guaranteed, and payment is by card on completion: all major cards except American Express, no cash.
