The third quarter of 2025 saw subdued deal activity, in part reflecting the traditional holiday season slowdown, but also closed with cautious optimism emerging in the UK technology sector. Beyond the seasonal lull, market sentiment remained measured, though several long-term investment announcements signalled growing confidence in the UK's digital future. Most notably, the UK government secured £150 billion of US investment from firms including Blackstone and tech giants Microsoft and Google. The deal will see the UK and US cooperate in key areas including hyperscale data centres, AI, quantum computing and nuclear power, with the potential to generate thousands of UK jobs at a time when growth and job creation remain challenging. Another positive piece of news is that Google and NatWest have announced a partnership with the Department for Business and Trade to help UK SME leaders implement AI tools. This comes off the back of a survey suggesting 59% of British SME owners have paused AI tool implementation ideas due to (ironically) time constraints. This is a positive development in supporting business owners to make the right investments to improve products, services and operating margins.
Mirroring UK M&A activity, growth in the UK economy stalled in Q3 2025, with the ONS reporting no growth at all during July and August. Inflation, while trending lower, remains above the Bank of England's 2% target, with the latest CPI reading of 3.8%, prompting policymakers to maintain a cautious stance with just one rate cut in the quarter. Further rate cuts are anticipated in 2026, however. The net result is that business confidence remains fragile, as higher financing costs and lower growth continue to weigh on investment appetite. The Chancellor’s pre-Budget speech will not have provided any encouragement to the markets.
Quarter on quarter, deal volumes fell 27% to 128, while deal values declined 54% to £4.3 billion (largely due to three sizeable transactions closing in Q2). Year on year, the picture was similarly muted, with volumes and values down 28% and 35% respectively. The slow down was more prominent in PE than in trade deals. We suspect the weaker performance reflects the economic uncertainty felt earlier in the year given the lead time on transactions. Encouragingly, early signs are that deal activity has bounced back in October, although we remain cautious given the potential impact of the Autumn Budget.
While deal activity this quarter has been relatively quiet by historical standards, the UK technology sector continues to demonstrate resilience in 2025, with PE buy and build activity and further consolidation in fragmented sectors such as managed service providers and telecoms resellers.
Business confidence remains subdued and an expanding UK budget deficit suggests the Autumn Budget later this month is unlikely to offer much in the way of encouragement to UK business or consumers. We remain optimistic, however, that UK Tech will continue to innovate and adapt, with the committed inbound investment from the US giving the potential for a significant boost.
Interestingly, there were 75 deal completions in October, an increase of 92% over September, suggesting a possible ‘catch up’ in activity following Q3. We will monitor the rest of 2025 with interest, particularly as the market looks to navigate the Budget and run-in to the festive period.

ESG compliance has been undergoing a transformation in recent years, from voluntary data capture and reporting to mandatory business-critical processing. The combination of more onerous regulatory requirements (including the UK's Sustainability Disclosure Requirements and TCFD reporting being replaced by UK Sustainability Reporting Standards) and corporate net-zero commitments having to be evidenced through formal transition plans, has created an attractive M&A/investment environment for leading software solutions.
While M&A activity has been fairly low key so far, we expect volumes to pick up over the next five years. Regulatory requirements are only heading in one direction and scalable solutions targeting efficient data capture and reporting are likely to attract further interest, particularly from private equity.
Carbon management consolidation: Companies providing emissions measurement and reporting tools as organisations grapple with complex disclosure obligations. Platforms with proven enterprise client bases and robust data verification will be prime targets.
Supply chain ESG solutions: Technology providers offering supplier engagement and sustainable procurement tools, including solutions that integrate with existing ERP systems. The need for this is likely to grow significantly as larger firms seek assurance over social and environmental standards in their supply chains.
Investor ESG Analytics & Disclosure Platforms: Solutions designed for asset managers, private equity firms, and institutional investors to track portfolio-level ESG performance, manage regulatory disclosures (e.g., SFDR, UK SRS, Transition Plans and European Union CSRD), and integrate sustainability metrics into investment decision-making.


US technology equities continued their strong outperformance, with the Nasdaq-100 (QQQ) advancing 12.6% during the quarter, driven primarily by large-cap technology companies capitalizing on the AI investment cycle.
By contrast, the FTSE 250 suffered a decline of 1.0%. Within UK markets, a notable divergence emerged between sectors: services companies declined 14.4%, while software businesses demonstrated relative resilience with a 2.2% decline.
Valuation multiples across our software and services indices remained broadly stable. Software companies traded at an average of 12.8x EBITDA during the quarter (up 0.1x quarter-over-quarter), while services businesses commanded an average of 10.5x EBITDA (up 0.5x quarter-over-quarter). These multiples are subdued however compared to the multiples of the tech heavy Nasdaq, which trades at an average EV/EBITDA of 20x+, fuelled by the AI rally; with a number of news headlines suggesting we may be entering into bubble territory.


*This does not include deals with no reported deal value
The most active sub-sectors in the lower mid-market this quarter were governance, risk and compliance, retail and leisure and IT consulting, each with five deals. These sub-sectors continue to be some of the most active for deals in a more subdued market.
Trade deals hold up better than PE deals: as noted above, PE backed trade deals (i.e. bolt on activity) were a strong feature of the market in Q3. In a risk-off market, we are not surprised to see fewer PE platform investments in the lower mid-market. The chart above comes with the usual health warning, however, that the data does not include deals without a reported value.
