R&D Cable Jointing provides LV cable jointing for new installations, diversions and repairs across the UK. We support principal contractors, utilities, ICPs and commercial clients with clean workmanship, site-ready delivery, and straightforward coordination. Based in Kent and working nationwide, we regularly support projects across Essex, London, Kent, Hertfordshire, Surrey, Suffolk, Cambridgeshire and Bedfordshire.
LV Jointing Services
LV works still demand standards similar to HV: correct preparation, controlled build-up, and proper reinstatement. We support programme delivery work as well as urgent repairs once access is available and site controls are in place.
- LV mains jointing — new installs and diversions
- LV service jointing and cable repairs
- LV cable terminations and cutout connections

LV Alongside HV
Many projects include LV enabling works alongside 11kV and 33kV activities — LV diversions ahead of HV cable routes, LV terminations at transformer LV connections, or LV STC panel works at substations. Using one contractor for both LV and HV scope reduces delays, simplifies coordination and keeps standards consistent across the job.
- LV diversions and enabling works for HV routes and substations
- LV terminations and plant installation alongside substation fit-out
- LV STC panel installation and commissioning
