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.

Call 020 8935 5206 or WhatsApp 07521 853 507 with a photo of the problem, the appliance make and model if there is one, and your postcode.
Yes, it's part of our normal patch, worked out of Dulwich. The rates section further down has the full picture. Quickest way to a straight answer on cost is a photo of the fault with your postcode, and any fault code the boiler is showing. We'll tell you whether it needs a visit or just an estimate.
The regular list here is short. A tap that won't stop dripping. A toilet that runs on after the flush, a shower mixer gone stiff behind the wall, a radiator that stays cold however long the heating runs, a boiler that's lost pressure again. We take on all of it, from a five-minute washer swap to a full pipework replacement.
The photo above is from a Camberwell job: a shower mixer valve that had been dripping into the bath for months, worn enough that the handle barely turned any more. A straightforward swap sorted it inside an hour, priced on the standard hourly rate, the same rate whether the leak's found under a sink or behind tiles.
Every job on that list runs off the same rate card we use across South East London.
On a recent Glow-worm Compact service nearby, a flue-gas analyser went straight onto the test point and measured oxygen, carbon monoxide and efficiency, checked against what the manufacturer allows. The readings came back well inside tolerance, carbon monoxide barely into double figures against an efficiency above 87%, so the appliance was signed off there and then. A fault code narrows the search but doesn't identify the failed part, so we test before anything gets swapped.
An annual service is £100 plus VAT, fixed, on any make of boiler, no brand restrictions. If a fault turns out to need parts, that gets priced as a proper estimate once we know what's actually wrong. Book a service alongside a landlord gas safety certificate and both are done on the same visit, £100 plus VAT each, £200 plus VAT total, no combined discount. Full detail on what a service covers, and when a repair is worth doing over a replacement, is on our boiler service and repair page.
A gas smell is different from a boiler fault: that goes to the National Gas Emergency line on 0800 111 999 before anyone rings us. The full what-to-do is in the questions further down.
Replacing a boiler outright is a bigger job than a repair. A like-for-like swap in the same spot is usually a single day's work; moving the boiler or changing the type of system can run to two or three days, mostly down to new pipework and flue routing. Either way we look at it in person before quoting, checking what's there now, where it needs to go, and what the gas and water supply can actually support.
There's no fixed from-price we can quote over the phone or in writing until an engineer's actually seen the job, because a like-for-like swap and a full relocation cost very differently. Full detail on the process, and current pricing, is on our new boiler installation page.
Radiators warm at the top but stone cold lower down are usually telling you the system's sludged up; it rarely means the boiler itself is failing. Fitting a magnetic filter clears the underlying problem, catching that debris before it wears at the heat exchanger or pump, and it's a fixed £230 plus VAT to supply and fit. Where the whole system needs it, a flush of up to ten radiators is normally one day's work at the day rate, plus approx £40 for the cleaning and inhibitor chemicals on top; a larger system takes longer, and we'd need to see it before pricing that part of the job.
Heat pump installs, macerator pumps and drain jetting sit outside what we take on directly, and for those we'll usually know a specialist worth trying. A hidden leak trace is different again: it's a chargeable inspection in its own right, because finding one isn't something anyone can promise before they've actually looked.
We take emergency calls here subject to engineer availability, so it's worth calling to check. Weekday daytime work is charged at the normal £100 plus VAT rate; evenings, nights and weekends move onto different bands. Weekday evenings, 6pm to midnight, are £145 plus VAT an hour, weekday overnight is £180. Weekends and bank holidays run £145 in the day, £180 in the evening and £270 overnight, all plus VAT, with no separate call-out fee whatever time it is.
If it's a gas smell rather than a burst pipe or a stuck valve, that's the one time to skip us and ring the National Gas Emergency line direct: 0800 111 999, free, any time.
Weekday daytime work is £100 plus VAT an hour, with the first hour charged as a minimum whether the job takes ten minutes or fifty-five, and every 15 minutes after that billed at a quarter of the hourly rate. For anything likely to run past about six hours, a day rate usually works out cheaper: £680 plus VAT on a weekday, £870 plus VAT at a weekend or on a bank holiday. It's the same rate everywhere we cover, so there's no postcode premium.
When | Rate | After the first hour |
Weekday 8am-6pm | £100 +VAT | £25 per 15 min |
Weekday evening (6pm-midnight) | £145 +VAT | £36.25 per 15 min |
Weekday overnight (midnight-8am) | £180 +VAT | £45 per 15 min |
Weekend/bank holiday day | £145 +VAT | £36.25 per 15 min |
Weekend/bank holiday evening | £180 +VAT | £45 per 15 min |
Weekend/bank holiday overnight | £270 +VAT | £67.50 per 15 min |
Payment is by card on completion, all major cards except American Express; we no longer take cash. Full detail, including every band, is on our rate card. A diagnostic visit is a paid call-out, priced at the hourly rate, never a free quote.
We're based in Dulwich and work Camberwell as part of our regular South East London patch, which means an engineer who already knows the area. These are a couple of recent Camberwell jobs.
We serviced a Glow-worm Compact combi due its yearly check. The analyser went on the test point and everything sat within tolerance, so it was paperwork and the service sticker.
The control panel in the photo is a Vaillant ecoTEC pro we were called in to diagnose. Unfortunately the visit turned into a safety issue. What we found meant the appliance wasn't safe to use, so we shut it down and issued the formal warning notice on the spot. Nobody enjoys that conversation, and we'd rather have it than leave a dangerous boiler running. The customer got the paperwork and a plain explanation of what to do next.
I still catch people topping a boiler back up to pressure every few days and treating that as normal, when it isn't. If it keeps dropping, something's letting water out somewhere or a valve has failed, and leaving it running like that for months usually turns a £100 diagnostic into a bigger repair once a part finally gives up. Get it looked at the first time it happens twice in a fortnight.

Pretty much the full list: burst pipes and leaks, boiler repairs and annual servicing, landlord gas safety certificates, central heating faults, radiators, taps, toilets, showers and the smaller pipework jobs in between. Everything's priced from the same rate card we use across the areas we cover.
No. One rate card covers every area we work in: £100 plus VAT an hour on a weekday daytime, first hour as the minimum, and the same £680 plus VAT day rate wherever the job is on our patch.
Yes. Recent ones include a Glow-worm boiler service with a full combustion check and a Vaillant fault diagnosis, both pictured above. We're careful about which photos get captioned to an exact street or postcode until that's confirmed, but the jobs themselves are real and recent.

The first hour, at whatever rate applies for the time of the call, £100 plus VAT on a weekday daytime, is the minimum. After that it's billed in 15-minute blocks, so an hour and a quarter means the first hour plus one extra block.
Yes: £680 plus VAT on a weekday, £870 plus VAT at a weekend or on a bank holiday. Once a job looks like it's heading past about six hours, the day rate usually works out better value than letting the hourly total climb past it. Same day rate wherever the job is.
Once a year. It keeps most manufacturer warranties valid, and it's the point where a small fault, a sticking valve or a marginal combustion reading, tends to get caught before it turns into a breakdown in the middle of winter. Summer's the easiest time to get it booked in.
Usually not on its own; most boilers lock out below around 0.5 bar as a safety feature. But it means water's escaping somewhere, or a valve or expansion vessel has failed. Topping it back up gets you through the evening, but if it keeps happening, the leak needs tracing properly.
Note the code down along with the boiler's make and model before you call; that alone often narrows it to ignition, pressure, the fan or a sensor before an engineer's even seen it. Send it over on WhatsApp with a photo and we can usually talk through roughly what's involved before booking a visit.
£100 plus VAT, covering up to two appliances, with £30 plus VAT for each one beyond that. It's issued by a Gas Safe registered engineer, registration 657719.
No. Ring the National Gas Emergency line straight away, free, any time: 0800 111 999. Don't touch switches or use any appliance, don't light anything, open windows and doors and get out of the property. We come in once that's dealt with, to sort the appliance itself.
For most systems, yes. Several manufacturers now make it a condition of the extended warranty on a new install, and it's a fixed £230 plus VAT either way, so fitting one before there's a problem is usually the cheaper order to do things in.
Just as often we're called out to Herne Hill SE24, Peckham SE15 and Dulwich Village SE21, all close enough that getting to any of them rarely adds much to the day. See every area we cover for the full South East London list.

Based on ten years of enquiries to one boiler-comparison site (2009–2019), not a full national census — but London topped the same study’s regional breakdown-rate table (6.08%), so the January spike shown here is, if anything, understated for SE5.
