UK Defence M&A Hits Record Pace in H1 2026 as Private Capital Reprices the Sector

Homeland July 29, 2026

A record 117 transactions in the first half of 2026 confirm that institutional appetite for UK defence and national security businesses has never been greater – with sovereign IP, proven government relationships and UK-based manufacturing commanding significant strategic premiums.

UK defence mergers and acquisitions have hit a record pace in the first half of 2026, with 84 trade transactions and 33 financial transactions recorded in H1 alone, according to new data from Heligan Group’s mid-year defence M&A report. The figures represent the strongest opening half-year performance the sector has seen and confirm a trend that has been building since the publication of the Defence Investment Plan: institutional capital is flowing into UK defence and national security at an unprecedented rate, valuations are rising, and the businesses best positioned to benefit are those with sovereign capability, proven government customer relationships and UK-based manufacturing and supply chains.

The character of investment activity is shifting as well as its volume. Private equity is now outbidding trade buyers in many contested processes, with dual-track processes between financial and strategic acquirers becoming standard practice across the market. Matt Croker, Corporate Finance Partner at Heligan Group, described the market dynamic plainly: institutional capital in defence and national security has never been greater, and private equity is increasingly willing to compete with – and beat – trade acquirers on valuation where the growth thesis is sufficiently compelling.

Several new platform investments from private equity have already been confirmed in H1, including Growth Capital Partners investing in Security HQ, Evity Invest in Martin Precision and Sullivan Street in ZenixAerospace. Notably, some of these newly backed platform companies are already completing bolt-on acquisitions, signalling that M&A is being used as an active and immediate growth strategy rather than a longer-term ambition. The speed of that activity reflects the competitive pressure to build scale and capability quickly in a market where the demand signal is clear and the window for early positioning is finite.

UAV platforms have attracted the most funding of any sub-sector, a trend directly linked to the operational evidence emerging from the Russia-Ukraine conflict. Autonomous systems have accounted for up to 80% of battlefield losses in Ukraine, and the commercial and strategic implications of that data point are being priced into investment decisions. Companies that have received venture and growth capital in the autonomous systems space are now being characterised as highly innovative, high-growth businesses with strong strategic value – both to financial investors seeking returns and to trade acquirers seeking to rapidly add capability.

The report also highlights maritime electronic systems as an area of acute strategic interest where supply is not keeping pace with demand. Strategic acquirers are actively seeking businesses in this space but finding fewer than expected – a scarcity dynamic that is likely to drive valuations higher for the businesses that have quietly built a position in maritime electronics. Law enforcement technology is identified as a catching-up sector, with M&A interest expected to arrive faster than many businesses in that market are currently anticipating.

The thematic shift in how acquirers are evaluating targets is as significant as the volume of activity. Sovereign capability is, in Croker’s framing, now non-negotiable. Businesses with sovereign IP, proven government customer relationships and UK-based manufacturing are attracting strong strategic multiples. Dual use – once treated as a secondary consideration or a marketing term – is now a primary lens through which MoD procurement is evaluated, and acquirers are pricing supply chain resilience directly into deal valuations. The Defence Investment Plan’s publication has, if anything, accelerated these dynamics: capital follows capital, and with the DIP now in place, Croker described a further step-up in M&A and investment activity as a near certainty into H2 2026 and 2027.

Private debt funds have also entered the picture in H1, with Croker noting a significant shift in activity as debt capital actively seeks exposure to the sector for the first time at scale.

For the UK defence supply chain

The Heligan Group data has direct and practical implications for businesses across the UK defence supply chain. For owners of SMEs and mid-tier businesses with sovereign capability, government relationships or specialist technology positions, the current environment represents a significant and potentially time-limited opportunity to explore strategic options – whether that is attracting growth capital, becoming a platform investment, or positioning as an acquisition target for a larger strategic buyer. For businesses already backed by private equity, the bolt-on acquisition activity confirms that financial sponsors are actively seeking to build scale through supply chain consolidation. And for the wider market, the repricing of defence valuations signals that the premium attached to proven, UK-sovereign capability is real, measurable and growing.
