Commercial

The electrical package has to land in the right week.

Commercial work is a programme problem before it is a technical one. Landlord conditions, base-build limitations, other trades and trading continuity decide the sequence.

How commercial work is structured

Four ways clients engage us, each with a defined output.

A

Fit-out package

Distribution, small power, lighting, containment and final connections delivered against a drawing set and a main-contractor programme.

Inputs
Drawings · landlord conditions · programme dates
Output
Priced package, phased programme, as-installed records
B

Small works & alterations

Reconfiguration of an occupied space: additional circuits, desk power, lighting changes, decommissioning and making safe.

Inputs
Site walk · access windows · continuity requirements
Output
Fixed scope per instruction, out-of-hours where needed
C

Planned maintenance

Scheduled inspection of distribution, emergency lighting function checks and minor remedial works with an asset and defect register.

Inputs
Asset list · criticality · site access rules
Output
Visit reports, prioritised defects, maintained register
D

Condition reporting

Inspection and testing of an existing installation with a written, prioritised report — kept separate from any remedial quotation.

Inputs
Extent agreed in advance · access to boards
Output
Written report, classified observations, optional quote

Continuity

Isolation is a plan, not an announcement.

In a trading premises, the electrical risk is rarely technical — it is the unplanned outage that takes tills, servers or refrigeration with it. Live premises are worked in phases with agreed isolation windows and a route back if something does not go as expected.

  • Access and hoursOut-of-hours, night and weekend working where the space cannot be interrupted.
  • Phased isolationCircuit-by-circuit transfer rather than a single site-wide shutdown, where the distribution allows it.
  • Trade coordinationSequencing agreed with the main contractor and other services trades so containment is not built twice.
  • Records at handoverAs-installed schedules, labelling and test documentation issued with the works, not chased afterwards.
