SHIELD ELECTRICAL SERVICES LIMITED

What SHIELD ELECTRICAL SERVICES LIMITED does

Shield Electrical Services Limited is a privately held, founder-led electrical contracting firm established in 1996 by John Salter in Swindon, Wiltshire, United Kingdom. The company provides project-based electrical, air conditioning, data cabling, and EV charging point installation and maintenance services to public sector, commercial, industrial, and residential clients across the South West, Thames Valley, Home Counties, and the M4 corridor. It employs approximately five to six qualified engineers who hold ECS cards, CITB certifications, and City & Guilds qualifications, and the firm is operated independently without external investors, subsidiaries, or parent company affiliation.

The business operates four core service lines under a consistent lifecycle model spanning consultancy, design, supply, installation, testing, handover, and aftercare. Electrical services form the core revenue stream and target social housing, local authorities, schools, retail units, offices, factories, and warehouses. Air conditioning and refrigerant services are delivered under REFCOM and CITB J11 F-Gas CAT1 accreditation, while data cabling serves offices and large commercial or industrial projects. EV charging point installation was added more recently under OLEV approval for the Workplace Charging Scheme (WCS) and Electric Vehicle Homecharge Scheme (EVHS), supported by an approved installer partnership with Rolec Charge Points.

The company generates revenue through project-based professional services engagements priced via quote following scope assessment, with no publicly disclosed pricing, recurring SaaS-like contracts, or subscription streams. Go-to-market is direct sales led, with the company website serving as the primary marketing channel and the team managing customer engagement from conception through completion. Differentiators rest on a dense stack of industry accreditations (NICEIC, SafeContractor, TrustMark, REFCOM, CHAS, Constructionline, OLEV), professional indemnity included as standard, manufacturer warranties up to five years, and nearly three decades of operating history in the region.
