A long-established industrial estate in Letchworth Garden City, home to twelve commercial and light-industrial tenants, was experiencing repeated LV trips. The landlord engaged us directly — being our own base, we'd done minor works there before and knew the network.
Scope: replace the underground LV distribution between the main intake and each tenant unit, joint into existing meter cabinets, and not interrupt trading hours.
What the job involved
- 800m of LV cable pulled across the estate in phased sections.
- 12 service connections into existing meter cabinets, all jointed under temporary back-feed.
- Tee-joints at four feeder pillar positions, replacing aged distribution boards.
- Insulation and continuity tests on every circuit before handover.
- Weekly tenant communications co-ordinated with the landlord.
Key challenges
- Twelve tenants, twelve different working patterns — sequencing required.
- One tenant ran 24/7 — those works planned for a Sunday afternoon under temporary supply.
- Existing duct routes were partially documented — trial holes used to verify before pulling.
Outcome
- Zero tenant trading hours lost across the eight-week programme.
- LV trips reduced to zero in the six months since handover.
- Landlord engaged us for the same treatment of a sister estate.
Round the corner from their yard and they took it as seriously as a job two hours away. Twelve tenants, none of them complained — that's the test.
