Three-phase power provides three separate AC supply phases instead of the standard single-phase supply in domestic properties. It is used in Sleaford commercial and industrial premises with high power demands — such as large motors, industrial machinery, CNC equipment, large commercial catering equipment, and commercial EV charging installations. If your single-phase supply is insufficient for your equipment requirements, or if your Sleaford business has machinery rated above approximately 3kW, three-phase is likely the right solution.

We liaise with the Distribution Network Operator (DNO) — typically Western Power Distribution or UK Power Networks — to arrange the three-phase supply connection to your Sleaford premises. This involves an application, network assessment and connection work by the DNO. We manage the whole process, from application through to the internal installation, metering and switchgear.

Three-phase installation costs in Sleaford depend on the scope of work — the size of the distribution board, the number of circuits required, cable runs, and whether a new DNO supply is needed. A new three-phase supply from the DNO involves a separate connection charge, and internal works are priced on the specific requirements. Call 01529 265060 for a site visit and fixed-price quotation.

Yes — we install three-phase socket outlets and isolators for workshop machinery, CNC equipment and industrial plant throughout Sleaford and Lincolnshire. We advise on the correct socket type, IP rating and cable sizing for your specific equipment, and provide a dedicated circuit with appropriate protection from the three-phase distribution board.

A typical three-phase installation for a Sleaford commercial or industrial premises takes 1–3 days for the internal works, depending on the scale. DNO connection lead times are separate and currently range from a few weeks to several months depending on network availability. We'll advise the realistic programme when we survey your Sleaford premises.
