We have the pleasure of providing access to Flex by Grosvenor flexible offices in London.
Established in 2021, Flex by Grosvenor is part of the Grosvenor Group, which was established in 1677.
Grosvenor Group was founded by the Grosvenor family, who developed much of Mayfair, Belgravia and Victoria throughout the 17th and 18th centuries and continues to make and manage neighbourhoods throughout London.
Flex by Grosvenor’s first property, 25 Eccleston Place (‘25 EP’) opened at the end of 2021 as a response to businesses seeking greater agility following the pandemic.
The 30,000 square foot property provided private offices and open plan co-working spaces for 2 to 50 people, together with meeting rooms and event facilities backed by a concierge service with staff handpicked from some of London’s top hotels.
Following the success of 25 EP, Flex by Grosvenor has grown its portfolio to 10 properties offering flexible offices in Mayfair, Belgravia and Victoria.
All of its properties provide flexible and sustainable workspaces with personalised hospitality-led services and premium amenity facilities.
In January 2025, it was reported that Norges Bank Investment Management (NBIM) had acquired a 25% stake in one of the parent company Grosvenor’s mixed-use London portfolios as part of a new joint venture (JV) between the two firms.
The £1.2 billion mixed-use portfolio comprised 175 office and retail assets around Grosvenor Street and Mount Street in Mayfair.
With $1.7 trillion in its arsenal, the Norwegian sovereign wealth fund could invest in various opportunities in London and globally and chose the joint venture deal with Grosvenor.
The deal represented the largest sale to outside investors from the Mayfair estate since the 1720s. Grosvenor advised it would continue to control and manage the portfolio.
In August 2025, the parent company of Flex by Grosvenor reported that in H1 2025, it had signed 62 new leases across all commercial property sectors in its Mayfair and Belgravia portfolio, covering 143,000 square feet and generating £11.7 million of rent, circa 5.5 per cent ahead of estimated rental value (ERV).
This meant that Grosvenor maintained a 97 per cent occupancy rate across its portfolio with office voids at just 0.7 per cent – significantly outperforming West End vacancy averages of 10.3 per cent.
The company attributed its 99 per cent office occupancy to the ongoing flight to quality across the London office sector.
Backed by an organisation with over 300 years of experience and more than 10,000 team members, clients of Flex by Grosvenor know they are in safe hands.
Grosvenor Group’s portfolio is varied and includes mixed-use developments, residential schemes and high-profile retail properties such as Liverpool One, which means that it can draw on its experience of managing those properties and transfer its exemplary customer service and amenity provision experience into its Flex by Grosvenor flexible office and workspace products.
Sustainability is at the heart of everything that Flex by Grosvenor does, and it endeavours to create places where communities, businesses, and nature thrive through its holistic approach to environmental and social sustainability.
Its ambition is to be a climate-positive, regenerative business, actively creating environmental benefits from its activities by 2050.
This will mean reducing emissions by 90% across its whole business, including buildings, developments and supply chain, by 2040, and achieving a significant net biodiversity gain by 2030.
Flex by Grosvenor also aims to send zero non-hazardous waste to landfill by 2030.
The London flexible office provider is also proud to be People Positive and recognises, measures and listens to the distinct needs of its community to make better-informed decisions to improve the well-being of all members.
This means it endeavours to improve people’s wellbeing in the places it makes and manages, helps local economies thrive by championing inclusive growth and diversity, and facilitates maximising the positive impact of its people and partners.
These efforts attract clients who wish to rent office space that aligns with their own high environmental, social and governance (ESG) standards.
All of Flex by Grosvenor’s offices are dog-friendly; however, one of the most popular features is the arrival of the daily tea trolley direct to the desk!
