Microsoft is hunting for a new London HQ along the Elizabeth Line as the city faces its tightest office market in years
Microsoft is on the hunt for a new headquarters in London, focusing its search on prime locations along the city’s Elizabeth Line amid a crunch in available high-quality office space.
The tech giant is eyeing sites stretching from Paddington in the west to Canary Wharf in the east, the Financial Times reports. Microsoft is seeking between 200,000 and 250,000 square feet of space and has been in discussions with developers and property companies in recent months, the newspaper said.
This move comes as London’s office market grapples with its lowest availability of premium space in years, driven by strong demand for modern, well-connected buildings. Central London’s overall vacancy rate stood at 7.4% at the end of Q4 2025, down 10 basis points from the prior year and below the long-term average.
However, the picture is even tighter for top-tier Grade A offices. In the City Core, vacancy is just 5.7%, 240 basis points below the 10-year average, while the West End Core (including Mayfair and St James’s) hovers around 4.1%.
A growing demand for space
Microsoft’s search reflects a broader trend among major firms vying for space in the capital’s financial hubs. Insurance broker Lockton and trading firm Jane Street are also scouting locations in London’s financial district, adding to the competition, the Financial Times reports.
The Elizabeth Line, which opened in 2022 and connects Reading in the west, where Microsoft already has a significant campus, to east London and beyond, offers excellent transport links that could appeal to the company for employee accessibility and hybrid work models.
Currently, Microsoft’s London presence includes its Paddington office at 2 Kingdom Street, designed for collaboration and learning.
The firm had previously explored a larger 500,000-square-foot consolidation in central London around four years ago but paused those plans amid global layoffs that cut 10,000 jobs, or 5% of its workforce.
In September 2025, Microsoft opted for an 80,000-square-foot HQ expansion at Thames Valley Park in Reading, but insiders suggest the London requirement is now being revived, albeit at a smaller scale.
The tightening market has shifted pricing power toward landlords for premium assets, with yields compressing in central London while rising elsewhere.
Annual take-up in Central London hit 10.6 million square feet in 2025, the strongest in six years and exceeding long-term trends, with 74% of leasing activity focused on Grade A space.
Forecasts predict similar demand in 2026, around 10.5 million square feet, underscoring sustained occupier interest in high-quality, ESG-compliant offices.
