Your office space

Osterley OR

Brick Lane

Our Osterley Campus is a 10-minute walk from Syon Lane train station. Or you can hop on one of our free shuttle buses that run to and from Osterley, Gunnersbury, Ealing Broadway and South Ealing tube stations. There are also plenty of bike shelters and showers.

On campus, you’ll find 13 subsidised restaurants, cafes, and a Waitrose. You can keep in shape at our subsidised gym, catch the latest shows and movies at our cinema, get your car washed, and even get pampered at our beauty salon.

Our Brick Lane office is based in the vibrant East End of London, an area known for its creativity and culture. The office is surrounded by a wide range of places to eat, meet and explore, making it a great spot to work and connect.

We’re well connected by public transport, with Aldgate East as the nearest tube station, and Liverpool Street Station a 10-minute walk away, offering Underground, National Rail and Elizabeth line services. If cycling is more your thing, bike parking, showers and changing facilities are available onsite. Car parking onsite is limited, however there are public car parks within a 5-minute walk.

If you believe in better, we’ll back you all the way.

Just so you know: if your application is successful, we’ll ask you to complete a criminal record check. And depending on the role you have applied for and the nature of any convictions you may have, we might have to withdraw the offer.
