Four Decades of Trusted Plumbing,
Gas & Heating Engineering
Across South East London.
Local homeowners, landlords and letting agents choose DHP London because every job is carried out by a Gas Safe registered engineer, and fully documented, first time, on time.
Built from the tools up by Danny Hensman.
The Hensman team on the job
DHP London Ltd was founded by Danny Hensman, a Gas Safe registered engineer with over 30 years on the tools across South East London. What began as a one-van operation servicing neighbours in Woolwich and Greenwich has grown into a trusted local firm covering the whole borough belt from Blackheath to Dartford.
We specialise in domestic plumbing, gas and heating: boiler installations and repairs, landlord gas safety (CP12) inspections, full central heating systems, power flushes, unvented cylinders, bathroom installations and 24/7 emergency plumbing. If it involves a pipe, a boiler or a bathroom, we've done thousands of them.
DHP London is a family business. Danny works day in, day out alongside his son, a qualified plumber, and a small team of trusted engineers. It means every job is overseen by someone whose name is on the van, and the standards stay the same on a boiler swap in Woolwich or a full bathroom in Blackheath.
Our customers are homeowners who want the job done properly the first time, landlords who need certificates issued reliably before a tenancy starts, and letting agents who need one engineer they can call for the whole portfolio. We hold Gas Safe registration number 180521 and trade as Company No. 06064438.
Certified engineering, transparent pricing and a job that lasts.
Gas Safe on every gas job
Every boiler, cooker and gas appliance job is carried out and signed off by a Gas Safe registered engineer under registration #180521. No exceptions, no subcontracted gas work.
Fixed, written quotes
You get a clear written estimate before we start. Our minimum call-out is £80 and pricing is agreed upfront, no surprise bills once the tools are out.
Manufacturer-backed warranties
New boiler installations carry the full manufacturer warranty, honoured because we install to spec, with paperwork registered in your name before we leave site.
Clean, respectful workmanship
Dust sheets down, boots off where needed, everything tidied before we leave. Your home is treated the way we'd want ours treated.
Documented for landlords & agents
Landlord Gas Safety Records (CP12) issued electronically shortly after the inspection, ready to forward to tenants and letting agents before the tenancy start date.
One engineer, one point of contact
You'll deal with the same team from the first phone call to the final commissioning, no call centres, no handoffs, no chasing.
