What happened

Excalon, the power and water services arm of listed engineer Renew Holdings, has bought Porter Brothers Holdings, parent company of PBU (UK) Ltd, in a deal worth up to £50m, Construction News reported this week. Renew is paying £31.1m up front in cash, funded from its own banking facilities, with a further £18.9m due over three years if the business hits agreed profit targets. The deal values PBU on sustainable operating profit of £3.9m.

PBU has operated since 2006 as a specialist contractor in extra-high-voltage cabling and directional drilling for the energy distribution networks. It is the fifth business Excalon has bought in just over a year, following Emerald Power, Edwards Diving Services, PWR-X and Electricity Distribution Engineering Services.

Why it matters

Renew's rationale is straightforward. Somewhere between £50bn and £60bn of committed network investment is coming through the current RIIO-ED2 and incoming ET3 regulatory periods, as distribution network operators rebuild and reinforce the cables that carry power from the grid to homes, depots and the new battery and data centre loads being connected every month. A specialist in high-voltage cabling and the trenchless drilling techniques used to lay it under roads and rivers sits right in the middle of that spending.

The acquisition trail matters as much as the target. Five purchases in just over a year tells you Renew is not assembling a portfolio for show, it is building full-service capability across diving, overhead lines, cable jointing and now HV cabling and drilling, so it can bid bigger, more complex grid packages without relying on subcontract chains it does not control.

What it means for careers and hiring

If you are a commercial or project management professional in the power, utilities or ground engineering sectors, this is a hiring signal worth watching closely. Acquisitions like this typically trigger an integration phase. PBU's management and delivery teams will likely stay in place initially, but expect Renew and Excalon to start layering in their own commercial, planning and HSE structures within six to twelve months, which usually means new roles at site manager, quantity surveyor and project manager level to support the combined order book.

More broadly, this deal is a marker for where the demand sits. Cable jointers, HV authorised persons, directional drilling engineers and utilities QSs are in short supply relative to the pipeline building up behind RIIO-ED2 and ET3, and that scarcity tends to show up first in rate inflation and then in counter-offers for anyone with a proven utilities CV. If your experience runs through DNO frameworks, grid connections or trenchless techniques, this is a good moment to make sure your CV reflects it clearly, because the firms chasing this spending will be looking.
