Non-compete clauses, once primarily applied to senior executives, are increasingly common across the UK workforce, affecting more than one in four workers, according to recent estimates. These agreements restrict employees from joining or starting rival businesses for a specified period after leaving their job. Last week, Prime Minister Andy Burnham committed to introducing legislation aimed at curbing the use of these clauses, continuing a review initiated last year by his predecessor, Sir Keir Starmer.
Proponents of reform argue that non-compete clauses hinder labour mobility, inhibit innovation, and hold back economic growth. Such contracts can prevent workers from moving to positions better suited to their skills or offering higher wages, disproportionately impacting low earners and young people. In some sectors, including professional, scientific, and information and communication technology industries, around 40% of employees are estimated to be bound by these agreements. Challenging non-compete clauses in UK courts is rarely straightforward, as employers must demonstrate their reasonableness, and legal processes can be costly, discouraging many workers from pursuing action.
Prime Minister Burnham has highlighted the stifling effect of these contracts on innovation. Historical examples underscore this point: California, which has prohibited non-competes since the late 19th century, became a global tech hub in part due to the departure of the so-called “Traitorous Eight” engineers and scientists in 1957 who founded new semiconductor companies. Research published in July by the OECD examined data from 15 advanced economies and found that a 10 percentage point increase in non-compete prevalence within an industry correlated with a 1.9% drop in labour productivity. This decline is attributed to reduced worker movement and slower knowledge diffusion. In the UK, existing challenges to labour mobility—such as high housing costs and inadequate transport infrastructure—are compounded by restrictive employment contracts.
Despite these concerns, the government’s proposals have faced resistance from large companies and sectors like finance, which argue that non-competes are necessary to protect intellectual property, cover investments in employee training, and maintain client relationships. Advocates of non-competes suggest these clauses help safeguard business interests from unfair competition. However, critics contend that alternative legal tools, such as intellectual property protections and non-solicitation agreements, could address these issues with fewer negative effects on labour mobility.
Among potential policy approaches, an outright ban on non-compete clauses is considered by some experts to be the most straightforward solution. They caution, however, that partial measures—such as exemptions based on salary levels, company size, or contract length—may introduce complexity and loopholes, reducing the effectiveness of reform. Removing non-competes broadly would likely compel businesses to attract and retain talent through improved compensation, working conditions, and contract terms rather than restricting employee movement.
As the UK government moves forward with its plans, attention will be required to prevent employers from circumventing new rules through other restrictive covenants. The debate underscores a broader balancing act between protecting business interests and fostering a dynamic, innovative workforce capable of adapting and thriving in a competitive global economy.
