One complete system.
Engineered as one.
PEP coordinates boilers, cylinders, distribution, gas, electrical controls and commissioning for substantial London homes — through one accountable team.

Domestic Installer SchemeCertified since 2010The PEP difference
The plant room is where the house becomes a system.
A high-performing home cannot be assembled as a collection of disconnected trades. The heat source, hot-water demand, distribution, power and control sequence all depend on one another.
PEP takes responsibility for those relationships. We plan the plant around the building, coordinate the heating and electrical interfaces, and remain accountable until the complete system has been balanced, tested and explained.
One surveyOne coordinated scopeOne accountable team
A complete installation
Every part considered. Every interface owned.
From the first pipe route to the final operating sequence, the system is developed as one connected piece of infrastructure.
Hot-water storage
Cylinder capacity, recovery, secondary circulation and simultaneous demand planned around how the home is actually used.
Distribution
Headers, pumps, pipe sizing and zoning arranged to deliver stable flow across radiators, underfloor heating and hot water.
Electrical & controls
Power, sensors, valves, pump control and boiler-enable logic coordinated with the hydraulic design from the outset.
Protection
Water quality, filtration, expansion, isolation and system protection built into the installation rather than added later.
Commissioning
Circuits balanced, operating sequences proven and controls explained before the completed system is handed over.

01 · DistributionWhole-home heating
Correct flow to every part of the property.
Heat generation is only the beginning. Comfort depends on stable circulation, sensible zoning and controls that match the way the home is occupied.
We coordinate the distribution serving radiators, underfloor heating, hot-water storage and secondary circulation. Pumps, valves, headers and pipe routes are selected and arranged as one hydraulic system — then balanced in operation.
- Multi-zone heating layouts
- Radiator and UFH coordination
- Pump groups and hydraulic separation
- Balancing, insulation and water quality
Designed beyond installation day
A plant room that can be understood, isolated and serviced.
Good plant-room design is measured years later — when an engineer can reach the equipment, identify the circuits and maintain the system without dismantling the room around it.
We plan equipment spacing, valve access, drainage, expansion, protection and control interfaces from the outset. The result is a compact installation without making serviceability the price of saving space.

Electrical & controls
Controls should command the hydraulics — not fight them.
A multi-zone system still needs to behave as one installation. We coordinate sensors, thermostats, valves, pumps, boiler-enable signals and hot-water priority so that each demand starts the correct sequence — and stops it cleanly when the demand is met.

04Operation is proven and balanced
Where the property requires it, the scope can include weather compensation, boiler sequencing, interlocks, fault signals and coordinated plant-room automation.
From survey to handover
One accountable route to a working system.
Clear decisions early. Coordinated installation on site. A system proven in operation before we leave.
Survey
We establish demand, plant space, existing services, access and the practical constraints of the property.
Coordinate
Heating, hot water, gas, electrical supplies and controls are developed as one installation before work begins.
Install
Our own heating and electrical teams deliver the agreed system, testing interfaces as the work progresses.
Commission
We fill, flush, balance, sequence, test and explain the system so it is ready to operate as designed.
Two disciplines. One responsibility.
Heating and electrical expertise inside the same team.
PEP does not leave the critical interface between the plant and its controls for someone else to resolve. Our heating and electrical leads coordinate the installation together — from service requirements and panel interfaces through to inspection, testing and final sequence checks.

Before we begin
Useful answers for a complete heating project.
If the project is already designed, send the drawings. If it is still taking shape, bring us in early and we will help define the practical route forward.
07825 268 43401Do you install complete central-heating systems?
Yes. PEP delivers complete systems for refurbishments, new installations and substantial London homes. The scope can include boilers, unvented cylinders, radiators, underfloor-heating circuits, pumps, distribution, gas services, electrical supplies, controls, testing and commissioning.
02Can PEP coordinate the heating, gas and electrical controls?
Yes. This is one of the principal reasons clients appoint us. Our gas, heating and electrical disciplines work as one team, so the hydraulic arrangement, electrical interfaces and operating sequence are considered together rather than passed between separate contractors.
03Can you upgrade an existing plant room?
Yes. We can assess an existing plant room, identify performance or serviceability problems and propose a proportionate upgrade. Depending on condition, that may involve controls, pumps, zoning, hot-water storage, distribution, water treatment or full replacement of the plant.
04Do you work with architects and main contractors?
Yes. We regularly work within larger residential refurbishments and can coordinate with architects, designers, builders and other specialists. Early involvement is particularly valuable where plant space, routes, electrical capacity or the construction programme affect the final system.
05What happens during commissioning?
The agreed circuits are filled, cleaned where required, vented and balanced. Pumps, valves, sensors, thermostats and boiler-enable signals are checked through their operating sequence, safety devices are tested and the controls are explained at handover.
06Which parts of London do you cover?
PEP works across Central, West and North West London, with regular projects in Kensington, Chelsea, Notting Hill, Holland Park, Chiswick, Hampstead, St John’s Wood, Maida Vale and the surrounding districts.
