Business Toolkit: Effective contracting and avoiding legal disputes

UK businesses are confronting a sharp rise in contract disputes precisely as sweeping legal reforms demand far tighter drafting and risk management to avert costly clashes.

Over the past five years economic instability – from Brexit aftershocks and pandemic disruption to volatile costs and policy shifts – has rendered many older agreements unworkable. A 2025 survey of 750 senior leaders found 35 percent had already faced contractual disputes, often over payments, performance or termination clauses strained by inflation and supply-chain friction.

The Federation of Small Businesses reports that around 70 percent of UK SMEs have encountered at least one commercial dispute, with contractual issues the most frequent trigger. These conflicts tie up cash, management time and relationships; unresolved cases have historically locked billions in SME funds nationwide.

The Employment Rights Act 2025, which received royal assent on 18 December 2025, intensifies the pressure. From 2026 the qualifying period for unfair-dismissal claims falls to six months, tribunal time limits extend to six months for most claims (effective October 2026), and “fire-and-rehire” tactics to force contract changes face severe restrictions from October 2026 except in genuine financial distress. Employment contracts without clear variation, flexibility or notice provisions now expose employers to quicker, uncapped compensation claims.

Consumer-side rules compound the challenge. The Digital Markets, Competition and Consumers Act banned drip pricing from April 2025, forcing total costs upfront on pain of fines up to 10 percent of global turnover. New subscription-contract requirements – clearer pre-contract information, renewal reminders and simple cancellation – arrive in 2026. UK firms selling to EU consumers must add a prominent “cancel” button by June 2026 or face cross-border enforcement.

SMEs bear the brunt: most lack in-house counsel, so a single flawed supplier agreement or staff contract can trigger cash-flow crises, regulatory probes or tribunal hearings that larger rivals can absorb. The result is heightened scrutiny of every commercial and employment agreement at a moment when economic margins are thin and counterparties more willing to litigate.
