What Cabling and Splicing Services does

Cabling and Splicing Services Limited, trading as CASS Worldwide, is a UK-based private infrastructure services contractor founded in 1998 and headquartered in Snitterfield, Warwickshire. The company delivers three integrated service divisions: Telecommunications (fibre network build, planning and design, project management, testing and commissioning, FTTH/FTTP deployment, copper removal, and customer connections), Energy (solar farm delivery including piling, mechanical installation and commissioning, HV/LV cabling, substation construction, and complete EV charging infrastructure), and the CASS Training Academy (accredited courses in NRSWA, CSCS, confined spaces and Openreach modules). Field teams, branded as Cable Enablement Gangs and Connections Engineers, are deployed across overhead and underground networks including PIA-accessed infrastructure under project-based contracts with major operators, and have delivered over 210MW of solar site works and full storm-damage remediation across UK solar farms.

Technology stack centres on physical infrastructure delivery rather than software: FTTH/FTTP deployment techniques including cable blowing, overblow, bundle, HDD (horizontal directional drilling), and dart testing, supported by a 1.5-acre in-house training facility with 17 full-size telegraph poles, over 900m of 4-way underground ducts with 28 BT boxes, 2 confined-space chambers, and an SQA-accredited training function. The business operates as a project-based professional services contractor with quote-based pricing, unit-rate day rates for field engineers and gangs (£180 per connections engineer; £300-£360 per 2-man cable enablement gang), and salary-banded design and coordination roles (£40-£60k utility designer; £28-£32k finance/project coordinator). Customer segments are wholesale and enterprise (telecom operators, ISPs, private fibre network builders, data centres, solar farm operators, EV asset owners), served exclusively through direct enterprise field sales with no channel partners or resellers. CASS reports turnover of £20m+ with zero debt and is family-owned, with no disclosed external investors.
