Applied Power Services

What Applied Power Services does

Applied Power Services (South Western) Ltd is a UK-based electrical engineering contractor founded in 1992 and headquartered in Tonypandy, Wales, with a second site in Royal Wootton Basset, Swindon. The company designs, installs, tests, commissions, and maintains high-voltage (up to 66kV and higher, with fault location capability to 400kV) and low-voltage electrical power systems for commercial and industrial customers, and operates three divisions under the APS Group of Companies Ltd holding entity: Applied Power Services (HV/LV power systems, switchgear, transformers, cable installation and jointing, fault location, packaged substations, civil engineering, earthing, and renewables), Applied Panel Services (LV panel design and build, BMS, MCC, LV switchgear, ATS, and ACB retrofitting), and Applied Professional Services (accredited HV and LV training and Authorised Person courses for healthcare, commercial, and MoD clients).

The company monetises through project-based professional services contracts and recurring maintenance agreements, with bespoke quoting per engagement and no publicly listed pricing. Its technology stack centres on conventional electrical engineering assets — including proprietary STX-40 fault-location test vans, pre-fabricated containerised substations, and custom BMS panels supporting Siemens, Trend, and Honeywell controllers — combined with OEM approvals from Brush, Lucy, Siemens, Schneider, and ABB. GTM is direct enterprise field sales: a multi-disciplinary in-house engineering team engages commercial and industrial clients across the UK via the company website, phone outreach, and ongoing maintenance relationships, with named enterprise customers including Tata Steel UK, Celsa Steel, The Royal Mint, Tarmac, Aston Martin, and GS Yuasa. Revenue, headcount, and ownership details beyond the founder-director Mark Nicholls are not publicly disclosed, and the firm carries ISO 9001, JIB Safe Contractor, ECA, Avetta, and Safe Contractor accreditations.
