What VJ Engineering does
VJ Engineering was a Rugby-based manufacturer of specialist vacuum tankers and provider of maintenance and repair services in the UK. Following the completion of its merger with Vallely Tankers (a Leeds-based subsidiary of CMR Utility Vehicles) in June 2026, the combined entity now operates under the Supervac brand (Supervac Ltd), with VJ Engineering absorbed into the new corporate structure. The company designs, builds, and supports bespoke vacuum tankers and trailers spanning four core product lines: new vacuum tankers, combination units and jet vac systems, ADR-compliant tankers for hazardous materials, and non-hazardous tankers for sewage, sludge, and industrial liquid waste. Each vehicle is engineered around customer requirements, with configurable tank capacities, stainless steel and specialist material options, multiple vacuum pump and rear-door configurations, hydraulic systems, wash-down systems, and chassis options across multiple vehicle classes. The technical offering is supplemented by a full aftermarket layer including refurbishment and remount services, scheduled maintenance, breakdown repairs, testing and certification, parts supply, fleet inspections, and used vehicle sales. The company targets operators across waste management, environmental services, utilities, construction, infrastructure, industrial cleaning, oil & gas/energy, and local authorities. The business model is direct, quote-based, and consultative: bespoke pricing per vehicle, enterprise field sales, multi-year contracts, and a nationwide UK service network anchored at two manufacturing facilities in Rugby (Midlands) and Leeds (North). The firm operates as a privately held company post-merger, with no venture capital or public ownership signals in the source data.
