What Specialist Power Systems does

Specialist Power Systems is an independent UK-based supplier of critical power protection products and services, founded in 2002 by Richard Yeeles (formerly a 10-year senior UPS service engineer at Eaton Powerware). The company operates from a single headquarters in Kempston Hardwick, Bedfordshire, holding simultaneous authorised partner status with the five leading UPS manufacturers — Riello UPS, APC by Schneider Electric, Eaton, Socomec, and Vertiv — and with six battery manufacturers (Yuasa, CSB, Fiamm, Enersys, Exide, C&D Technologies).

Its product portfolio spans online/double-conversion, line-interactive, and offline/standby UPS topologies from 400 VA desktop units up to 800 kVA data centre systems, including modular and scalable lines (Riello Multi Power, Sentryum Rack, NextEnergy NXE) plus lithium-ion-ready configurations. Supporting products include diesel generators (PRAMAC, Kohler SDMO), central battery systems compliant with EN 50171/EN 54-4, UPS power distribution units, and 19-inch equipment racks. Recent launches include the Riello Sentryum Rack (2021), NextEnergy 800 kVA (2021), Sentinel Dual2 (2025), and Sentinel Pro2 (2026).

The business model combines hardware resale, recurring service and maintenance contracts (24/7/365 with guaranteed 4hr/8hr/Next Business Day engineer response), professional services (battery replacement, impedance/conductance testing, monitoring, disposal, installation and commissioning, site surveys, load bank testing, repairs, capacitor replacement), and a usage-based hire fleet. Pricing is quote-based and project-specific. Customers span data centres, healthcare (NHS, Great Ormond Street Hospital), higher education (Oxford, Cambridge), pharmaceuticals (GSK), technology (Google, Cyberfort), industrial manufacturers, and public-sector estates, with over 2,500 installations completed across more than 20 years.
