Why Greenwich customers keep calling us back.
Greenwich is a demanding place to run a plumbing and heating business. The housing stock ranges from Georgian and Victorian conversions off Crooms Hill and Royal Hill to river-facing new builds on the Peninsula, and each type behaves differently once you get a spanner on it. We know where the awkward stopcocks hide, which streets still have lead branches on the incoming main, and which developments were signed off with combi boilers that are already struggling under family demand. That local memory is the reason customers in Greenwich keep calling Danny back after two decades.

Neighbourhoods we cover
- We serve Greenwich
- Greenwich SE10 and Blackheath-side SE3 are inside our core service belt. We are based locally in South East London, which means most Greenwich visits are a short van hop rather than a cross-London trip.
- Response times
- Typical response for a booked call in Greenwich is as soon as we can schedule you in. For genuine emergencies, a live leak, no heat with a baby in the house, a suspected gas smell, Danny will always try to divert a van as quickly as we can during our 9am–9pm office hours.
- Property types we know
- We work daily on the borough's mixed stock: Georgian and Victorian townhouses converted into flats, ex-local-authority blocks off Trafalgar Road, riverside apartments on the Peninsula, and 1930s semis on the Blackheath fringe. Each has its own quirks, from combi boilers oversized for a studio to system boilers running unvented cylinders in a townhouse loft.
- Common Greenwich jobs
- The three jobs we book most often in Greenwich are boiler repairs on ageing combis in period conversions, full boiler replacements when annual services throw up an unsafe verdict, and bathroom refurbishments where a Victorian layout needs modern plumbing hidden behind the tiles.
What we get called out for in Greenwich.
The jobs below make up the bulk of our week inside SE10, SE3. Every one is priced in writing, Gas Safe compliant.
Boiler Repairs
Cold radiators, no hot water, an F1, F22 or E133 lockout code, we've seen every fault on every major boiler over the last 30+ years. Fixed-price diagnostic, honest recommendation on repair versus replace, no upsell.
Boiler Installation
A quiet, efficient, A-rated boiler installed by a Gas Safe engineer with over 30 years on South East London homes, lower bills, hotter showers, and the manufacturer warranty registered in your name before we leave.
Gas Safety Engineer
Suspect a gas leak, need a safety inspection, or moving in and want the appliances checked before you use them? A Gas Safe registered engineer on-site as quickly as we can, with the tools, tightness testing kit and combustion analyser to prove the job's been done right.
Bathroom Installation
A new bathroom without the six-trades chaos. Danny sits with you, sketches the layout, sources fittings, then plumbs, tiles and finishes with a small trusted team, clean site, agreed timeline, one point of accountability from first sketch to final silicone bead.
Central Heating Installation
A complete central heating system designed around your home, from heat loss calculation and boiler sizing through radiators, zoning, controls and commissioning. One team, one accountable install, warrantied in writing.
Power Flushing
A proper high-flow reverse flush that strips a decade of magnetite sludge out of your radiators and pipework, restoring flow, quieting the boiler, cutting gas bills, and unlocking manufacturer warranty on any new install.
Concrete reasons, not marketing lines.
Every fact below comes from how we actually run the business, over 30 years continuously trading from the same Plumstead yard, one Gas Safe registration.

The problems we see again and again in Greenwich.
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 SE10, SE3 actually looks like.
Victorian and Georgian conversions
Period homes off Royal Hill, Crooms Hill and the Ashburnham Triangle usually still have the original pipe routes hidden behind cornicing and floorboards. We take the time to trace the actual system before quoting, so a boiler swap does not end up destroying a lath-and-plaster ceiling.
Undersized combis in family flats
A lot of two- and three-bed conversions were fitted with 24kW combis a decade ago. Once a second bathroom or a rain shower goes in, the boiler cannot keep up. We size correctly and quote a like-for-like or upgrade with the honest trade-offs written down.
Peninsula new-build apartments
Newer blocks around the Peninsula are typically fed off communal heat networks or compact system boilers in utility cupboards. Access panels, warranty rules and building management sign-offs all need managing, we handle that admin as part of the job.
Hard-water scale and heat exchangers
Greenwich is on hard London water. Scale is the number one killer of combi heat exchangers in SE10. We fit magnetic filters and inhibitor properly on every install, and offer power flushing where an older system is clearly sludged rather than broken.
Landlord and rental turnover
A big share of Greenwich flats are let. We turn CP12 landlord gas safety certificates around quickly, flag any borderline appliances in writing, and can take over annual servicing so a portfolio does not slip out of compliance between tenancies.

Yes. We cover SE10 across West Greenwich, East Greenwich, Maze Hill and the Peninsula, plus SE3 on the Blackheath side. If you are inside the borough boundary, you are inside our core service area.

Our minimum labour charge is £80, quoted up front. Most diagnostic visits fall into a fixed one-hour window; parts are billed at trade cost plus a clear markup. You will always have a written price before we start the work.
Are you available for emergencies in Greenwich?+
Our office phones run 9am–9pm, seven days a week. Live leaks, no-heat calls with vulnerable occupants and suspected gas smells are prioritised for prompt dispatch inside SE10 and SE3.
Can you install a new boiler in a Victorian conversion?+
Yes, that is one of the most common jobs we do in Greenwich. We survey the existing pipe runs, flue route and gas supply first so the quote reflects the real building rather than a template price.
