Read our guide to find out what type of flexible workspace is offered by Sub800

Sub800 offers managed office spaces in Central London that range in size from below 800 square feet to over 8,000 square feet, suiting companies seeking space for between 10 and 110 desks, and with several hundred properties, all space requirements in between.
The diverse and eclectic portfolio includes Grade-II listed offices, refurbished warehouses, sleek, newly refurbished townhouses, and modern office buildings with amenities like cycle storage and showers.
Within these properties is a wide range of options as the spaces are fully customisable, so space can be open-plan or partitioned and can have private amenities such as kitchens, WCs, outdoor terraces and reception area, or an occupier can choose communal options.
Clients can choose self-contained floors, multiple floors or whole buildings, and office suites that offer the flexibility to expand or contract.
Sub800 manages the customisable offices, so there is one monthly cost that includes rent, service charge, insurance, and managed services, and the managed services include a concierge service, bespoke snack packages, cleaning and technology packages.
The Sub800 managed office portfolio covers Central London and offers properties in the City of London, Midtown, the West End, and East London.

We have the pleasure of providing access to Sub800 office space in London.
Sub800 was founded in 2019 as a niche provider of sub-800 square feet office suites in Central London.
However, due to increased demand, it pivoted to offering managed offices of all sizes in response to the pandemic.
Its CEO witnessed the struggle that employers that leased office space faced in enticing their workers back to the office as the workplaces didn’t offer the amenities that serviced offices offered.
This inspired Sub800 to bridge the gap between traditional and serviced offices by enhancing leased offices with the experience-driven services commonly found in serviced spaces.
Sub800’s portfolio grew to circa 500,000 square feet in the space of 5 years and now offers several hundred managed offices in the sub 800 square foot category and larger managed offices for teams requiring space for 25, 50, 75, and 100+ desks.
The portfolio caters to companies seeking managed suites, managed floors, multiple managed floors, and whole buildings.
The portfolio covers multiple locations across Central London and contains an eclectic range of properties, including refurbished Georgian townhouses, converted industrial buildings, and modern Grade A office towers.
Its large collection of private managed workspaces includes offices with cinemas, roof terraces and gyms with a supportive ecosystem that includes amenities such as concierge services.
Clients design their bespoke workspace together with Sub800’s Partnership Services team and enjoy support from the in-house legal team to simplify the agreement process.
Similar to serviced offices, Sub800’s managed office pricing is packaged into one monthly cost, inclusive of rent, service charge, insurance and managed services, keeping accounting both simple and predictable.
Following its pivot to offering large managed offices in London and rapid growth, Sub800 rebranded in July 2024.
The rebranding was led by Simon French, the Global Creative Director of Tommy Hilfiger and former Senior Designer at Soho House.
Sub800’s growing portfolio offers a diverse range of workspace options, and with them, the managed office provider continues with its mission to revolutionise office rentals by seamlessly connecting businesses with workspaces that really work for them. They aim to provide everything a business needs without unnecessary stress.
To complement the amenities and services of Sub800’s offices, the properties are always conveniently located close to great amenities and transport links.
Sub800’s commitment goes beyond providing desks. It believes in fostering genuine connections and creating an environment where work feels uniquely personal and inspires authentic success.
It believes its spaces are platforms for innovation, collaboration, and unparalleled growth.
The well-being of its occupiers is important to Sub800, and it works with ClassPass, allowing team members to book fitness classes, well-being and beauty treatments, allowing them to have the time to wind down.
In 2024, five years after launching, Sub800 was named in the Tally Workspace Top 100 Workspaces Awards, won the Flex and The City award for Rising Operator, and grew its portfolio by 42%.
The provider was named in the Top 100 Workspace Awards for its managed offices at Hend House on Shaftesbury Avenue in Covent Garden.
The 1920s art deco Grade II listed building was formerly the headquarters for Disney’s Industrial Light & Magic, where blockbuster films such as Ant-Man, Spectre, and Star Wars were produced.
The basement houses a private cinema that has been tastefully refurbished, and the property also offers an outdoor roof terrace, meeting rooms and a grand reception space.
With such a diverse portfolio, Sub800 enjoys an equally varied occupier base. This includes businesses such as food technology company Appetite App, branding, graphic and artwork solutions provider Artwork Solutions, publisher 10 Magazine, outfitters New & Lingwood, Danish furniture designers Ferm Living, financial company Smart Insider, and AI-powered performance marketing, data and eCommerce specialists Pierian Digital.
