The challenges
What is at stake
Switchboards, distribution, lighting, sockets, protection and earthing: we build and bring into compliance the electrical installations of your buildings, from the main switchboard to the point of use.
Continuity of service
A fault on one circuit must not cut off a whole floor, let alone the server room.
Our answer
Circuits separated by use, discriminating protection, dedicated supplies for critical equipment.
Control of consumption
Energy-hungry lighting and no metering make it impossible to cut the bill.
Our answer
LED lighting, presence detection and sub-metering by use.
Compliance
Technical inspections, insurers and operators require a compliant, documented installation.
Our answer
Up-to-date diagrams, labelled circuits and remedy of inspection findings.
Architecture
An architecture designed in layers
Power flows from the supply point down to every socket and light fitting, through a chain of protection designed to isolate a fault without shutting everything down.
Every installation is delivered tested, labelled and documented, for simple operation and maintenance.
- Layer 01
Incoming supply & main switchboard
Supply point, main protection, metering and main outgoing feeders.
- Layer 02
Distribution
Cables and busways to each floor and area, sized with spare capacity.
- Layer 03
Sub-distribution boards
Protection and labelling of the circuits in each area.
- Layer 04
Lighting & sockets
Normal and emergency lighting, sockets and dedicated circuits.
- Layer 05
Earthing & protection
Earth electrode, equipotential bonding and surge protection.

Sectors
Where we have deployed it
Maintenance & 24/7 support
This system can be covered by a preventive and corrective maintenance contract, with priority response on critical sites.
See the plansCan you bring an old installation up to standard?
Yes. We start with an assessment, then propose a prioritised programme of work that can be carried out in stages.
Can you work without cutting power to the whole building?
Work is organised by area and any necessary shutdowns are scheduled with you, outside sensitive hours.
Does switching to LED pay off?
Generally yes: much lower consumption, longer life and less maintenance. We estimate the savings before the work.
