Dale Power Solutions

What Dale Power Solutions does

Dale Power Solutions Limited is a UK-based critical power systems provider founded in 1935, headquartered in Scarborough with regional offices in St Albans and (since April 2025) Aberdeen. The company designs, manufactures, and services Uninterruptible Power Supply (UPS) systems (Commercial UPS from 1 kVA to 1 MVA and the proprietary Erskine Industrial UPS line with 57 years of heritage and 20+ year design life), diesel generators in open set, canopy, and containerised configurations from 20 to 3,000 kVA, and Battery Energy Storage Systems (BESS) ranging from compact 30-100 kW units (Dale BESS NBN) to multi-megawatt containerised systems. BESS offerings are built around BYD lithium-iron phosphate (LiFePO4) Blade battery technology integrated via Eft Systems GmbH, with stated system capacities up to 50 MWh and 10-year battery warranties. The firm holds deep sector-specific certifications including HTM 06-01 (healthcare), WIMES (water utilities), EN50171 (life safety), Achilles Supply Line and UVDB, JOSCAR, NICEIC, Constructionline, CHAS, and SafeContractor.

Revenue is generated through a blended model: hardware sales of UPS, generators, and BESS units; project-based installation and commissioning; spare parts and refurbishment; managed fuel services; and, most importantly, recurring maintenance and service contracts delivered through a UK-wide network of 80+ engineers providing a 4-hour mainland GB response time, 24/7 emergency support, and remote monitoring. The company maintains more than 10,000 generators and UPS units annually across 153,500+ maintenance hours and supports 800+ healthcare sites. Go-to-market is enterprise field sales targeting 12 verticals (healthcare, defence, marine oil and gas, utilities and renewables, telecoms, data centres, emergency services, construction, transport, manufacturing, finance and government, facilities management), supported by direct consultation, a UPS sizing tool, an energy calculator, and an extensive content marketing presence.

The customer base features multi-year anchor contracts with NHS Property Services (3,500 NHS buildings), Network Rail, National Grid, Bouygues, ISS, and Mitie, alongside specialised deployments such as WIMES-specified UPS for a North West England water utility and a Gibraltar telecoms operator. Recent strategic activity has been notable: the April 2025 acquisition of Calibre Power Electronics strengthened offshore UPS capabilities in oil and gas, while 2025 partnerships with Ablerex and GTEC Europe expanded the UPS and EN50171 life-safety portfolios respectively, and the in-house BESS product line was formally launched. Ownership is private with no disclosed institutional shareholders; revenue is not publicly reported.
