CAN Geotechnical acquired by RSK Group 

Acquirers in UK specialised construction M&A focus on a consistent set of value drivers: a long-dated forward order book tied to public infrastructure programmes, repeat client relationships with Tier 1 contractors and infrastructure operators, technical accreditations and safety records that underpin tender qualification, depth of specialist workforce, and the absence of single-client concentration. A geotechnical contractor with a clear category specialism — slope stabilisation, rockfall protection, or piling, for example — and a track record of delivery on transport and utilities programmes commands a meaningfully stronger valuation in a structured sell-side process than a generalist subcontractor of equivalent revenue.

Strategic acquirers in the UK environmental and engineering consultancy sector typically value specialist contractors on an adjusted EBITDA multiple, with the multiple uplift driven by strategic fit — specifically, whether the target closes a defined capability gap in the acquirer's service stack. RSK Group's acquisition of CAN Geotechnical is a clear example: CAN added specialist construction delivery to a group already strong in investigation and design, completing the lifecycle proposition the acquirer could offer to transport, energy, and utilities clients. In UK mid-market M&A — where deal values typically sit in the £5m–£100m range — businesses that demonstrably extend the acquirer's addressable scope of work usually receive a premium to the prevailing sector multiple.

The UK geotechnical and ground engineering market is structurally attractive to buy-and-build acquirers for three reasons. First, demand is underpinned by long-cycle public infrastructure programmes — HS2, Highways England capital works, Network Rail renewals, and utilities upgrades — which provide multi-year visibility on the forward order book. Second, the market remains fragmented: many specialists are founder-led businesses in the £5m–£25m revenue range, well-suited to acquisition by a larger consolidator. Third, acquirers can capture genuine cross-sell value by integrating ground investigation, geotechnical design, and construction delivery under a single group. The RSK Group acquisition of CAN Geotechnical sat squarely within this pattern — RSK's 11th acquisition in 19 months, supported by a £140m funding package from Permira Credit.

The outcome for the workforce in a specialist construction acquisition depends on the acquirer's integration model and the deal terms negotiated. Buy-and-build acquirers in the environmental and engineering consultancy sector typically retain specialist workforces in full — the specialist capability and accreditations are central to the value being acquired. In the RSK Group acquisition of CAN Geotechnical, the 250-strong workforce moved across with the business; founders Neil Foster and Andy Wingfield continued in leadership roles after completion; and CAN joined RSK's geosciences and engineering division as an integrated specialist unit. A sell-side advisor with sector experience negotiates workforce and leadership continuity provisions explicitly in the heads of terms — not as a post-completion expectation.

Optimal exit timing for a UK specialised construction founder is shaped by personal, business, and market factors in combination. On the personal side: clarity about what comes next and whether the business still energises you as a leader. On the business side: a consistent revenue trajectory, a forward order book that extends 18–24 months beyond completion, and a management team capable of supporting a transition without the founder on every client call. On the market side: an active buy-and-build cycle in the sector, well-funded acquirers with stated acquisition theses, and a public infrastructure pipeline that supports the buyer's growth thesis. The strongest UK specialised construction exits are planned several years in advance — typically when the founder is still energised by the business but able to picture a credible successor.

Key-person dependency is one of the most common valuation deductions in lower mid-market UK specialised construction M&A. Where client relationships, technical sign-off authority, or commercial decisions rest disproportionately with the founder, acquirers will price in the risk of a post-completion drop in revenue or capability — typically through a lower headline multiple, an earn-out structure, or a longer founder retention period. The strongest specialist contractor exits are prepared 12–24 months in advance: senior management is given visible client-facing responsibility, sign-off authority is distributed, and the founder's role in the business is repositioned as strategic rather than operational. A sell-side M&A advisor with specialised construction sector experience identifies the specific dependencies that need to be unwound and the sequence in which to do it.

A structured sell-side M&A process for a UK specialised construction business typically runs between six and twelve months from advisor appointment to legal completion. Timelines are influenced by the readiness of financial and operational documentation, the number of bidders engaged, the depth of buyer due diligence — particularly on safety records, accreditations, and contractual liabilities — and the speed of legal negotiation. Market conditions can extend the timeline: the CAN Geotechnical mandate was paused for several months as conditions in the wider M&A market shifted, and resumed and completed to a strong outcome. A well-run process is built to absorb that kind of pause without losing the buyer relationships or commercial momentum already established.

Choosing the right sell-side M&A advisor for a UK specialised construction business comes down to three things: sector-specific valuation fluency, a verifiable track record of completed transactions with strategic and buy-and-build acquirers, and the discipline to stay with the process through difficult market conditions. A generalist advisor can run a process; a specialist understands the sector multiples, the active acquirer universe, the safety and accreditation requirements that affect due diligence, and the workforce-continuity provisions that founder-shareholders typically want negotiated into the deal.
