Radlett Farm New Electrical Upgrade

---

We were instructed by the client to carry out a full electrical infrastructure upgrade at the Radlett site, working in close coordination with UKPN to deliver an increased power capacity and new distribution arrangement to support both existing facilities and future operational demands.

The project involved upgrading the existing incoming electrical supply from a 100A three-phase and neutral (TPN) supply to a new 200A TPN mains supply, providing significantly increased capacity for the site. The works included liaison with UKPN for the incoming service alteration, coordination of shutdowns, supply changeover procedures and final energisation of the new installation.

As part of the upgrade, DDS installed a new 125A TPN sub-main supply to a newly constructed workshop unit complete with CT metering arrangement, allowing accurate monitoring and future scalability for the client’s electrical consumption requirements. The installation included new containment systems, sub-main cabling, distribution equipment and protective devices designed and installed in accordance with current BS7671 regulations and utility requirements.

Additional works included the full installation of lighting and power throughout the new workshop unit, incorporating energy-efficient LED lighting, socket outlets, local distribution boards and power supplies to support operational equipment and day-to-day workshop activities. All systems were fully tested, inspected and commissioned upon completion, ensuring a safe, compliant and reliable electrical installation ready for occupation and long-term use.
