Why Woolwich customers keep calling us back.
Woolwich has changed enormously in the last decade: Royal Arsenal, Elizabeth line, thousands of new apartments, but the plumbing and heating stock is still overwhelmingly a mix of Victorian and Edwardian terraces, 1930s semis and post-war council builds. That is the housing we cut our teeth on, and it is the housing most of our week is still spent inside. Being local matters here: we can be at a burst pipe in Plumstead Road faster than most firms can pick up the phone.
Our base is in South East London · approx 5–10 minutes on a normal traffic day.

The problems we see again and again in Woolwich.
Local heating and plumbing issues are rarely random. They follow the era of the property, the pipework, the water conditions and the way the house has been extended. Here is what our diary in SE18 actually looks like.
Ageing combis in ex-council stock
A large share of SE18 flats and maisonettes were fitted with entry-level combis in the last upgrade cycle. Many are now well past the point where repair makes sense. We give a plain-English 'repair vs replace' answer with numbers, not a sales pitch.
Small bathrooms that need re-planning
Original Woolwich terraces and maisonettes typically have very small bathrooms with awkward soil-stack positions. Danny designs the layout with you before ripping anything out, so the finished bathroom actually works for the family that lives there.
Royal Arsenal apartments
Newer Riverside blocks use compact system boilers or communal heat networks. Warranty conditions and management-company sign-offs must be respected. We handle both, and stay inside the building's rules on flue routes and isolation.
Landlord compliance
SE18 has a heavy rental market. Missing or late CP12 certificates are a real legal exposure for landlords. We book annual gas safety checks in blocks so a portfolio does not slip, and issue certificates as soon as we can.
Hard water and sludged systems
Older Woolwich central-heating systems are usually full of magnetite sludge that quietly kills pumps and heat exchangers. Power flushing plus a properly fitted magnetic filter typically restores full output without the cost of a new boiler.

Questions we hear from Woolwich customers.
Are you actually based in Woolwich?+
Yes. DHP London Ltd is a London-based business. Woolwich isn't a 'service area' for us in the marketing sense, it is where our yard is.
How quickly can you get to a boiler emergency in SE18?+
Being inside SE18 means we can usually be with you as quickly as we can for a genuine emergency during our 9am–9pm office hours. Non-urgent bookings are typically slotted in as soon as we can schedule you in.
What's the minimum you charge in Woolwich?+
Our minimum labour charge is £80. That covers the initial diagnostic visit; parts are on top and always quoted in writing before we fit them.
Do you cover both sides of the river in SE18?+
SE18 is entirely south of the Thames, so yes, the whole postcode is inside our core coverage. Cross-river North Woolwich (E16) is outside our normal patch; call us and we'll be honest about whether it makes sense.
Can you issue a landlord CP12 in Woolwich the same week?+
In most cases yes, often within 24–48 hours of the request. Danny is Gas Safe registered (#180521) and can inspect boiler, hob, cooker and gas fire in a single visit.
Do you fit boilers in the Royal Arsenal Riverside apartments?+
Yes. We work regularly on compact system boilers in Riverside flats, following the block's rules on flue routing and building-management sign-off. If a job needs communal-heat-network access, we tell you honestly at the quote stage.
What brands of boiler do you install in Woolwich?+
Mainly Vaillant, Ideal, Baxi and Glow-worm. All come with the manufacturer warranty (typically 7–10 years) registered in your name,.
Do you take on full bathroom refurbishments in Woolwich?+
Yes. Danny will design the layout with you, price the whole job in writing, and coordinate the tiling, plumbing, plastering and electrical safe isolation from start to finish.
