Roadnight Taylor has warned that grid-connection delays are beginning to restrict UK industrial growth, with manufacturers underestimating the time and complexity involved in securing additional electrical capacity.
The specialist consultancy surveyed 200 senior industrial decision-makers across Great Britain for its Powering 2030 report. Twenty-eight per cent expect their organisations to expand by between 26% and 50% during the next three years, although existing grid constraints are already influencing whether projects can proceed.
Among respondents that had experienced connection delays, 60% reported a direct business effect and 34% said growth had stopped altogether. One third had encountered project delays, 32% faced increased costs, and 25% reported disruption to energy-transition plans.
The results reveal a marked difference between companies with direct experience of the connection process and those approaching it for the first time. Twenty-eight per cent of experienced directors considered connection timescales a significant barrier, compared with 8% of those yet to encounter the issue.
Respondents without direct experience expected a connection to take an average of 3.2 years, whereas Roadnight Taylor said a major project can require closer to eight years. Location, network reinforcement, queue position, planning, land rights, technical studies, and equipment availability all influence the final programme.
Electricity supply is often treated as a utility matter to be resolved after land, machinery, building, and investment decisions have advanced. At an electricity-intensive plant, available capacity can determine whether the proposed production process is technically and commercially viable at the chosen location.
Electrification is increasing the demand placed on established industrial connections. Electric furnaces, heat pumps, boilers, charging infrastructure, compressors, motors, data systems, hydrogen production, and automated machinery can collectively exceed the capacity for which an older site was designed.
Where network reinforcement is required, the project may depend on new substations, upgraded cables, transformers, protection work, planning approvals, or construction elsewhere on the transmission or distribution system. The manufacturer’s own installation can be ready while the upstream network remains incomplete.
Connection uncertainty also changes project finance. Industrial investment is assessed against the point at which machinery begins producing saleable output, so a delayed energisation date extends the period during which capital is committed without the expected revenue.
Energy price adds another pressure. Forty-seven per cent of respondents were concerned about electricity costs, while 25% believed overseas competitors held a distinct energy-cost advantage.
A quarter were considering locating new plants outside the UK and 18% were examining whether to move their entire operation abroad. Not every option will become a relocation, although electricity infrastructure is clearly entering site-selection decisions alongside labour, land, taxation, logistics, and customer access.
Grid constraints are already visible in automotive production. Growth in on-site renewable generation at UK vehicle factories is reducing purchased electricity and supporting decarbonisation, yet manufacturers continue to identify connection delays as a restriction on further electrification.
Solar generation, batteries, private networks, demand flexibility, and energy-efficiency measures can reduce peak demand from the grid, but they do not provide a universal alternative to a strong connection. Continuous industrial processes require dependable power across shifts and seasons, including periods of low renewable output.
Flexible operation can support projects where loads may be shifted without affecting quality, delivery, or equipment life. Batteries can manage short-duration peaks and provide market services, although their commercial performance depends on utilisation, degradation, electricity pricing, and the duration of the underlying constraint.
Three quarters of surveyed directors expect the National Energy System Operator’s connection reforms to benefit their organisation. The reforms are intended to move viable and strategically aligned projects through the queue rather than reserving capacity indefinitely for developments that are unlikely to proceed.
Queue reform cannot remove the physical work required to reinforce networks. Transformers, switchgear, cables, substations, protection systems, planning approvals, construction teams, and commissioning resources remain subject to manufacturing and engineering lead times.
Industrial companies therefore need to examine available capacity during the earliest stages of site and project selection. Connection offers, reinforcement triggers, securities, liabilities, programme risk, and alternative operating strategies should be evaluated before major capital commitments become difficult to reverse.
Seventy-two per cent of respondents believe Britain risks falling behind as industrial economies move towards lower-carbon production. Generation targets alone will not close that gap unless electricity reaches factories at the capacity, cost, reliability, and timetable required by investment programmes.
Grid connection has become part of production strategy rather than a late-stage engineering service. Early assessment creates options around location, technology, phasing, flexibility, and on-site generation, whereas discovering the constraint after ordering equipment can leave a completed project without the power needed to operate.
