R&D Cable Jointing delivers turnkey substation solutions for DNOs, private networks and EV infrastructure across the UK. Whether it's a GRP or full brick-built fit-out, we handle every aspect of the installation from civil handover through to DNO adoption and energisation, with precision, compliance and a clean finish.
We provide one contractor for the full HV and LV substation scope, reducing handover complexity, keeping accountability clear and simplifying programme management for the principal contractor or ICP.
Turnkey delivery. We take the substation scope from civil handover through to DNO adoption and energisation. One contractor, clear accountability, no gaps in the programme. Send us the project details and we will confirm availability and a delivery plan.
Beyond standard ICP and DNO connection substations, we support a growing range of specialist substation types where the installation requirements differ from a standard secondary substation:
Commercial EV charging hubs, from kerb-side schemes to motorway service area rapid charging installations, require dedicated 11kV substations once the total charger load exceeds what the local LV network can supply. We deliver the full substation scope for EV charging infrastructure, integrating with the charge point operator's programme so the supply is ready when the CPO is on site. See our Commercial EV Charging Infrastructure page for more detail.
Solar farms and battery energy storage systems require dedicated 11kV or 33kV substations for grid connection. Whether it's a ground-mounted BESS installation in a field or a rooftop solar connection on a commercial building, our approach is the same, systematic, safe and delivered to specification. See our Solar, BESS & Wind HV Jointing technical guide for more detail.
Private HV networks serving industrial estates, data centres, commercial campuses and large facilities require the same standard of installation as DNO substations, often with tighter programme constraints and the additional complexity of working around live operations. We have experience delivering substation works in live industrial environments and understand the permit and outage coordination requirements.
Substation environments demand strict controls, planning and clear communication. We align with your site safety rules, permits and working systems to deliver work efficiently without disruption to live operations.
Based in Kent, working nationwide. We regularly support substation programmes across London, Kent, Essex, Hertfordshire, Surrey, Suffolk, Cambridgeshire and Bedfordshire, and travel nationally for the right scope. Contact us at info@rdjointing.co.uk or call 0330 043 6689.
