Delivering reliable plumbing solutions across London since 2009
Ducazu was established in 2009 by three qualified plumbers who shared 27 years of combined industry experience. Starting from a single van operating in West London, we built our reputation by completing every job to British Standard specifications and responding to emergency calls within 90 minutes.
Today, we operate six fully equipped service vehicles covering Greater London. Our team includes 14 Gas Safe registered engineers, 8 qualified plumbers, and 3 bathroom installation specialists. We handle approximately 2,400 service calls annually, from fixing dripping taps to installing complete central heating systems.
We maintain partnerships with manufacturers like Worcester Bosch, Ideal Heating, and Grohe, ensuring access to genuine parts and extended warranties. Our work complies with Building Regulations Part G and Part L, and we hold £5 million public liability insurance.
Fixed-rate quotes provided before starting work. No hidden charges or surprise fees. You receive a detailed breakdown showing labour, materials, and VAT separately.
Every engineer holds current Gas Safe registration and City & Guilds Level 3 plumbing qualifications. We verify credentials annually and require ongoing training in new technologies.
All installations carry a 24-month labour guarantee. Parts are covered by manufacturer warranties ranging from 2 to 10 years depending on the product.
We provide 2-hour arrival windows and send SMS notifications 30 minutes before arrival. Our average response time for emergencies is 75 minutes across London zones 1-6.
Our work speaks through measurable outcomes. We've installed 340+ combination boilers, renovated 180+ bathrooms, and resolved over 8,000 emergency repairs since opening. Each project is documented with before-and-after photos and customer feedback.
We specialize in properties built between 1900-1950, understanding the unique challenges of cast iron pipework and outdated drainage systems common in London homes. Our team has worked on Victorian terraces, Edwardian conversions, and post-war council flats throughout Kensington, Chelsea, Hammersmith, and surrounding boroughs.
We handle installations, repairs, and maintenance across residential and commercial properties in London. Each project is completed to British Standards with certified materials and documented work.

Most plumbing issues in London properties are addressed within 2-4 hours of your call. We maintain a fleet of fully-equipped vans positioned across SW3 and surrounding areas, ensuring our engineers reach you quickly when problems occur.
Every member of our team holds Gas Safe registration and City & Guilds qualifications. With an average of 8 years in the plumbing trade, our specialists handle both modern systems and older Victorian-era pipework common in London homes.
After inspecting the issue, we provide a complete breakdown covering labour, parts, and VAT. The quoted price remains unchanged regardless of how long the repair takes. No surprises appear on your final invoice.
Our vans stock over 200 common plumbing components including copper fittings, PVC pipes, washers, valves, and modern push-fit connectors. This inventory means most jobs are completed during the first visit without delays for parts ordering.
All completed work comes with a written guarantee covering both parts and labour for one full year. Should any issue arise with our repairs or installations during this period, we return to resolve it at no additional charge.
We install dual-flush toilets, aerated taps, and modern shower valves that reduce consumption by 30-40% compared to older fixtures. These upgrades lower your Thames Water bills while meeting current Building Regulations for water conservation.
