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.
If you need a plumber in Dulwich Village, the houses set the terms before anyone opens a toolbox. Most of what we do around SE21 is inside Georgian and Victorian houses, plenty of them listed or standing inside the conservation area, and old pipework changes how a job gets approached. We're Gas Safe registered, registration 657719, there's no call-out fee, and weekday work starts at £100 plus VAT an hour with the full rate card published before you book. Call 020 8935 5206, or WhatsApp a photo of the problem to 07521 853 507.

Yes, we cover Dulwich Village and the whole SE21 postcode from our Dulwich base. Weekday work between eight and six is £100 plus VAT an hour, the first hour is the minimum charge, and anything after that is billed in 15-minute steps. There's no separate call-out fee. Send your postcode, a photo of the problem and, for a boiler, the make, model and any fault code, by WhatsApp to 07521 853 507, and we'll usually tell you the likely job and cost before anyone gets in the van.
The calls from Dulwich Village follow a pattern, mostly old-house plumbing:
Day to day it's mostly small faults. A dripping tap normally needs a new washer or cartridge. A damp patch on a ceiling is more often a pipe joint or a waste upstairs than the spot where the stain actually sits, so we find what failed before anyone lifts a board.
A boiler that won't fire, keeps losing pressure or is showing a fault code doesn't automatically mean an expensive part needs replacing. We test the appliance before condemning anything, because a fault code tells us where the boiler noticed a problem, not which part has actually failed. Common culprits are a faulty diverter valve (heating but no hot water, or the reverse), a stuck pressure sensor, or a fan on its way out. We repair and service any make of gas boiler, no restrictions, though Vaillant, Worcester Bosch, Ideal, Baxi and Viessmann come up often in Village houses simply because that's what's fitted locally. Full detail on how we diagnose and price a boiler repair or service is on its own page.
An annual service is a fixed £100 plus VAT, worth doing every twelve months. Skipping it can void the manufacturer's warranty on a young boiler, and it's the easiest way to catch a fault before it fails mid-winter. The case comes off, the burners and heat exchanger get checked, and combustion is tested with a flue-gas analyser. A gas fire is serviced separately, that's its own one-hour job at the normal hourly rate, not part of the CP12's extra-appliance charge. Book a CP12 alongside the service and both are done in one visit: £100 plus VAT for the service, £100 plus VAT for the CP12 covering up to two appliances (£30 plus VAT each extra), a straight £200 plus VAT together with no discount for booking them side by side.
A straight like-for-like combi swap in a Village house is normally a day's work. Moving the boiler to a new location, or changing the type, takes two or three days because of the extra pipework and, in a listed property, the extra care over where anything gets chased or drilled. We'll always weigh up whether repair still makes sense before recommending a swap: a well-installed boiler usually manages ten to fifteen years or more, and repair is often the better answer while it's still youngish and the fault is one component. See our boiler installation page for the fuller process.
Out-of-hours help is available in the Village, including 24-hour cover for a genuine emergency, subject to which engineers are free that night. The rate changes with the time, not the job: weekday evening £145 plus VAT an hour, weekday overnight £180, weekend daytime £145, weekend evening £180, weekend overnight £270, all with the same first-hour minimum and no call-out fee. A pipe that lets go at 2am on a Sunday is billed at the weekend overnight rate for that period, nothing added on top of the published bands.
If you can smell gas, don't call us first. Call the National Gas Emergency Service on 0800 111 999, free, 24 hours a day. Don't touch switches, don't light anything, open a window if you safely can and get out. We come in once the gas engineers have made things safe.
Same rates as everywhere else we work, the Village doesn't pay extra for the postcode.
| When | Rate |
|---|---|
| Weekday daytime (08:00-18:00) | £100 +VAT |
| Weekday evening (18:00-00:00) | £145 +VAT |
| Weekday overnight (00:00-08:00) | £180 +VAT |
| Weekend/BH daytime | £145 +VAT |
| Weekend/BH evening | £180 +VAT |
| Weekend/BH overnight | £270 +VAT |
The first hour is the minimum charge, then billed in 15-minute steps. Bank holidays run at the weekend rates. No call-out fee at any hour. Payment is by card on completion, all major cards except American Express, cash is no longer accepted. Bigger jobs, over about six hours, usually work out cheaper on the day rate: £680 plus VAT weekday, £870 plus VAT weekend. A power flush of up to ten radiators is normally a day at that day rate, plus around £40 for the cleaning chemicals; larger systems take longer and get priced once we've seen the pipework. The full rate card, including the day rates, is on our rates page.
Most of the houses we work on around Dulwich Village are Georgian or Victorian, and a good number sit inside the conservation area. Original lead or iron mains are still in use here and there, imperial copper won't take a modern fitting without the right adaptor, and pipes are often tucked under original floorboards or above lath-and-plaster ceilings we'd rather not open unless we have to. On a listed building we say which parts of the job are likely to be awkward before we start, and where the work might need listed-building or conservation-area consent, we raise that rather than cutting first and finding out afterwards.
One job in the Village came from a couple fed up with poor pressure upstairs. The house still had its original vented cylinder, fed by gravity from a loft tank, and gravity only gives you so much. We stripped the tank out and fitted a Megaflo unvented cylinder running straight off the mains. Unvented work is regulated: it needs the right qualification, the correct safety controls and a discharge pipe run to outside. The difference in the shower was the first thing they noticed.
A basin mixer in another Village house had seized solid with limescale. Hard water across most of South East London scales up the inside of a tap body, not just the spout, and this cartridge had welded itself in. Forcing a seized cartridge out on an older mixer usually cracks the tap, and the part can rarely be matched anyway, so a new tap went in: supplies off at the isolation valves, swap, flush through. The flow came straight back.
In a Village house, the expensive part of a leak is rarely the pipe, it's whatever sits underneath it. Before winter, find your stopcock and check it still turns. In houses this age it's often painted solid, and the ten minutes it takes to free it can save a ceiling.

Yes, out-of-hours cover is available in the Village around the clock, subject to which engineer is free that night, at the published evening, overnight and weekend rates above. For a burst pipe, turn the water off at the stopcock first, then call. There's no call-out fee even at 3am, so you're paying for time worked, not for the hour on the clock.
Yes, it's most of what SE21 asks of us. We route pipework to avoid original plaster and joinery where we can, fit the correct imperial-to-metric adaptors on old copper, and say before starting which parts of a job are likely to need extra care. Where a listed building might need conservation-area consent, we raise it rather than opening something up and finding out afterwards.
A Gas Safe registered engineer from Paul the Dulwich Plumber's team, with the work overseen by Paul Orzeszak, Senior Engineer & Head of Heating and Plumbing. Every engineer carries a Gas Safe ID card; ask to see it when they arrive.
Yes, our work is guaranteed, terms vary by job, and the business carries £2,000,000 public liability insurance. Payment is by card on completion, we don't take cash, and American Express is the only card we can't process.
No, payment is by card once the job's finished. We accept all major debit and credit cards except American Express. Cash stopped being accepted across the whole business, not just in the Village, so the answer's the same wherever you're calling from.
Send your postcode, the appliance make and model, any fault code and a photo by WhatsApp to 07521 853 507, and for a defined job like a service or a CP12 we can often give a written estimate without a visit. Where a fault needs diagnosing on site, that hour is charged at the normal rate like any other visit.
Yes, one visit, two jobs. A CP12 covering up to two appliances is £100 plus VAT, extra appliances beyond that are £30 plus VAT each, and an annual boiler service is £100 plus VAT. Booked together that's a straight £200 plus VAT, no combined discount, and it's popular with Village landlords between tenancies. Out-of-hours visits cost more, per the rates above.
A machine pushes cleaning chemicals round the whole heating system at high flow to break up sludge, then an inhibitor goes in to slow it building up again. Up to ten radiators is normally a day at the day rate, £680 plus VAT weekday or £870 plus VAT weekend, plus around £40 for the chemicals. Bigger systems take longer and get priced once we've seen the pipework.
Rule of thumb: a well-installed boiler manages ten to fifteen years or more. Repair usually makes sense while the boiler's younger and the fault is one component; replacement starts to make more sense once repairs become a habit or a major part like the heat exchanger fails on an older unit. We'll say which side of that line yours is on, and why.
Any make of gas boiler, we don't limit ourselves to a short list of brands. Vaillant, Worcester Bosch, Ideal, Baxi and Viessmann come up often in Village houses, but that's what we see locally, not a restriction on what we'll take on.
No, call the National Gas Emergency Service first, free, on 0800 111 999, available 24 hours. Don't touch switches or light anything, open a window if you safely can, and leave the property. We come in afterwards, once the gas engineers have confirmed it's safe to do any plumbing or boiler work.
The Village sits one street from our home ground. We also work regularly in East Dulwich SE22, Herne Hill SE24 and Camberwell SE5, and across the full South East London coverage area. For urgent problems at odd hours, the emergency call-out page explains how the out-of-hours bands work.
