Rejoining the EU single market could deliver a significant economic boost to the UK, recovering up to 90 percent of the financial impact caused by Brexit, according to a study by Frontier Economics commissioned by the organization Best for Britain. Proponents argue that closer ties would alleviate trade friction, though economists warn that returning to past terms will not fully erase years of accumulated losses.
Economic Projections and Trade Impact
Research from Frontier Economics estimates that improving trade ties with Europe could generate a £92 billion boost to the UK Gross Domestic Product. According to a spokesperson from Deutsche Bank, re-entering the single market would eliminate regulatory friction and red tape, directly benefiting the services sector, which accounted for 41 percent of UK exports in 2025. This step would restore productivity and investment confidence, countering the long-term drag of Brexit-related uncertainties.
However, economists urge caution regarding the realistic limits of such a move. Thomas Pugh, chief economist at RSM, notes that rejoining could create unrealistic expectations about its immediate financial advantages. Pugh explains that while adopting previous terms would yield net economic benefits, it cannot compensate for the 4 to 6 percent economic loss already incurred since Brexit due to altered migration patterns, lower investment, and reduced trade volumes.
Political Strategies and Public Opinion
The debate has gained traction in domestic politics as a potential path for electoral strategy. Nick Boles, a former government minister under David Cameron and current Labour adviser, has suggested that negotiating a closer trading relationship could secure a decisive political victory and establish a lasting governing legacy. Boles advocates for a “European Confederation” model designed to secure single market access and youth mobility rights without requiring full Eurozone membership or adherence to mandatory freedom of movement rules.
Public sentiment shows openness to closer European relations. Polling data from YouGov indicates that 59 percent of Britons favor closer ties with the EU, while 50 percent support rejoining the single market, contrasted with 26 percent in opposition. Tom Brufatto, executive director of policy and research at Best for Britain, states that polling demonstrates a voter preference for EU integration, particularly among segments leaning toward the Labour Party.
Political Hurdles and Compromises
Despite potential economic gains, the political feasibility of single market re-entry remains complex. Membership requires accepting the four freedoms of the EU and contributing to the bloc’s budget, terms that have historically divided British voters and politicians. While figures like Andy Burnham have expressed long-term aspirations for the UK to rejoin the EU, policymakers must evaluate the extent of concessions required to balance economic integration with national political realities.
