The British government has, for the third time in 18 months, deferred its planning decision on whether China may construct a 700-room embassy complex at Royal Mint Court next to the Tower of London. The Interior and Foreign Offices now have until 20 January 2026 to complete further security assessments after MI5 and GCHQ raised concerns that the mission could be used for state-backed espionage owing to its proximity to fibre-optic infrastructure that carries a large share of Europe’s financial data traffic.
Beijing bought the derelict Royal Mint site in 2018 for £255 million and has argued that the new campus is essential to provide consular and visa services for the 300,000-plus Chinese nationals who live, work or study in the UK each year. Until the project is approved, China says it cannot consolidate six scattered diplomatic buildings across London, meaning continued delays for corporate visa processing and higher security costs for British police tasked with guarding multiple facilities.

Local residents, Hong Kong pro-democracy activists and several cross-party MPs oppose the scheme, citing human-rights issues and fears of “tech-enabled surveillance creep” in a densely populated part of Zone 1. City planners are also wrestling with how to enforce the Diplomatic Premises Act if neighbouring properties demand compensation for security-related road closures.
For multinational employers, the stalemate prolongs uncertainty over whether additional Chinese consular capacity—especially for same-day business visas—will come online in London or remain constrained. Mobility managers should therefore continue to factor in the current 5-7-day processing times for standard PRC visas and advise executives to submit applications well in advance of travel.
Analysts note that the episode highlights a wider strategic dilemma for Prime Minister Keir Starmer’s government: how to balance economic engagement with China, Britain’s third-largest export market, against tightening national-security controls at the border. A negative decision could trigger retaliatory measures affecting UK companies operating in mainland China, while approval without robust safeguards risks parliamentary backlash. Either way, global-mobility teams should monitor the ruling’s knock-on effects for both inbound and outbound visa regimes early in the new year.
