PORTLAND ROAD, NOTTING HILL W11

A Complete Plumbing & Heating Transformation for a Six-Storey London Townhouse

When a Home Rises Six Storeys, the System Behind It Has to Work Harder

In tall London townhouses, comfort issues are rarely subtle.
Pressure drops. Uneven heat. Long waits for hot water. Systems that work on one floor — and struggle everywhere else.

At Portland Road in Notting Hill, the brief was clear:
deliver strong water pressure, efficient heating, and reliable comfort across all six floors — without wasting space or energy.

This wasn’t about replacing equipment.
It was about engineering a system that works vertically, efficiently, and reliably in a compact London footprint.

PROJECT SNAPSHOT

✦ Location: Portland Road, Notting Hill, London W11
✦ Property Type: Six-storey townhouse
✦ Scope: Full plumbing and heating system replacement, commercial boiler, pressure boosting, unvented hot water, UFH, radiators, three bathrooms, commissioning and handover

THE PROBLEM

Multi-storey homes expose the weaknesses in poorly designed systems faster than any other property type.

This townhouse was experiencing the classic symptoms:

• Pressure loss at upper floors

• Inconsistent heating across levels

• An ageing system stretched beyond its limits

• Inefficient performance and rising running costs

A standard domestic setup simply wasn’t enough.
The home required commercial-grade performance, scaled intelligently for residential use.

THE SOLUTION

We delivered a high-performance, space-efficient mechanical system, designed specifically for six-storey vertical living.

✔ Elco Commercial Gas Boiler

A powerful, high-efficiency boiler providing reliable heating performance across all floors.

✔ Megaflo Unvented Hot Water Cylinder

Ensures strong, consistent hot water delivery to every bathroom and outlet.

✔ Duty Point Scuba Tank (Pressure Boosting)

Stabilises and boosts water pressure throughout the full height of the property.

✔ Wet Underfloor Heating (Lower Floors)

Discreet, even warmth across living areas with efficient heat distribution.

✔ Radiators on Upper Floors

Responsive heating where faster warm-up was required, fully balanced with the UFH system.

✔ Three Fully Plumbed Luxury Bathrooms

Concealed pipework, wall-hung WCs, concealed valves, and premium fixtures throughout.

OUR PROCESS

✦ 1. Design & Planning

We worked closely with the homeowner and builder to design a system suited to a six-storey structure.

This included:
– Heat-loss calculations
– Flow-rate and pressure modelling
– Dual-circuit heating design (UFH + radiators)
– Plant-room space optimisation
– Long-term service access planning

This stage ensured performance was built in — not hoped for.

✦ 2. Installation

The installation focused on precision and finish:

• Concealed primary and secondary pipework throughout

• Elco commercial boiler connected to dual heating circuits

• Duty Point Scuba Tank integrated for stable vertical pressure

• Megaflo cylinder installed for high-pressure hot water

• Full plumbing installations to three bathrooms

Every element was installed with long-term reliability in mind.

✦ 3. Testing & Handover

All systems were:
✔ Pressure-tested
✔ Flushed and balanced
✔ Commissioned to manufacturer standards

The homeowner received a full walkthrough covering boiler operation, controls, thermostats, and pressure management — ensuring confidence from day one.

CHALLENGES & SOLUTIONS

Vertical Distribution

Six floors created pressure and temperature challenges.
The Duty Point Scuba Tank ensured stable water supply at every outlet.

Compact Plant Space

A bespoke layout allowed all major components to fit efficiently without compromising service access.

Efficiency Targets

The Elco high-efficiency boiler and advanced digital controls delivered improved performance with lower energy consumption.

THE OUTCOME

The completed system delivers exactly what the home needed:

✅ Consistent water pressure across all six levels
✅ Even, efficient heating via UFH and radiators
✅ Intuitive controls for effortless day-to-day use
✅ Compact, serviceable plant-room design
✅ A robust system built for longevity

This project demonstrates how engineering-led design transforms complex London homes.

WHY THIS MATTERS FOR MULTI-STOREY LONDON HOMES

Tall townhouses demand more from plumbing and heating systems. Without proper design, performance drops — and costs rise.

This project shows how the right approach delivers comfort, efficiency, and peace of mind across every floor.
