As companies continue to invest in Buckinghamshire, it has been announced that MP Callum Anderson has chosen Challenge House as his Bletchley constituency office.
In order to be accessible and on hand to support local companies and constituents, the Member of Parliament for Buckingham and Bletchley wanted to be located at the heart of his constituency and opted for an office space at the thriving business hub.
The award-winning serviced office space, part of the Landmark property portfolio, is home to a growing number of regional and global companies.
Callum said: “My team and I chose Challenge House as the base for our Bletchley office because it’s in a great location and already home to lots of businesses, big and small. For me, it was really important to be based somewhere that shows I’m supporting local businesses and backing Bletchley.”
Navraj Johal, Chief Marketing Officer at Landmark, said: “Landmark are delighted that Callum and his team chose our serviced offices at Challenge House, as their base for the important work they are doing across the Buckingham and Bletchley constituency and the country.
“Challenge House is a great place for people who are looking for serviced office space in Milton Keynes. We look forward to the exciting times ahead for Bletchley and know that Callum and his team will have a major role to play in its ongoing success.”
Challenge House has seen an increasing influx of big businesses, SMEs, start-ups and charities choosing the popular hub for their operations as Bletchley continues to benefit from significant investment in the Oxford-Cambridge Growth Corridor, helping to boost commercial growth in the area.
The government has long recognised the Oxford-Cambridge Corridor as a globally significant region, and there is now a renewed push for growth. Bletchley sits at its heart, helping to drive an estimated £78bn boost to the UK economy by 2035. Positioned between two of the world’s leading university cities, Milton Keynes will benefit from major investment in East-West Rail, providing fast, modern links between Oxford and Cambridge.
This strategic location makes it an ideal base for cutting-edge businesses in life sciences, Al, and advanced manufacturing, while creating thousands of homes and high-quality jobs. With strong infrastructure and exceptional growth potential, the city is poised to play a pivotal role in building ‘Europe’s Silicon Valley’ and powering Britain’s innovation future.
Callum, who previously worked at the London Stock Exchange Group, draws on his experience to champion entrepreneurship in his role as an MP. He recently established the Bletchley Investment Taskforce to drive inward investment and is actively campaigning for a second entrance at Bletchley station, making the town an even more appealing place to live, work and shop.
He is also known for being a visible MP across Bletchley, and regularly hosts surgeries and local summits to hear feedback from constituents directly.
Callum said: “Representing Buckingham and Bletchley is the greatest privilege of my life. This is an area rich in history, innovation, and community spirit – from our vibrant towns and villages to the dynamic city at the heart of the constituency. At the General Election, we made history together: the first Labour MP for North Buckinghamshire since 1966 and for Bletchley since 2005. Every day, I feel proud and grateful to serve the people who call this incredible place home, and I’m committed to working tirelessly to help it thrive.”
Locally, Callum attends as many business events as he possibly can. Recently he was invited to deliver the opening statement at an event on AI safety for SMEs, at the Milton Keynes Tech Week where he talked about how the Government is supporting Al opportunities for the region and beyond, adding that events like the MK Tech Week were ‘vital, bringing together entrepreneurs, business leaders, government and academia to build the networks and ideas that will drive responsible innovation.
