Broker to move London office into new 250,000 sq ft development

Lockton has announced that it will almost double its London footprint by moving into a new office development in the city.

The broker is currently based in the St Botolph Building in London, where it has occupied around 130,000 square foot of office space since 2010.

The new 250,000 square foot office is located at The Mark on 47–50 Mark Lane and represents the largest pre-let in London to date in 2026. Practical completion of the development is targeted for Q1 2029.

The broker said the move almost doubles its London footprint and establishes a London headquarters for Lockton’s International regions, supporting its businesses outside of North America.

The London office of Lockton Re, the global reinsurance business of Lockton, will also relocate to the new office.

EJ Hentenaar, chief executive at Lockton Europe, said: “This is an exciting milestone for Lockton and a significant investment in our future.

“It reflects the support we have from our clients, the talent we continue to attract and our shared belief with our global network on the importance of having a strong, independent broker in the heart of the vital London insurance market. 

”This move underscores our ambition to keep growing and evolving, 20 years after we opened our first European office in London. The Mark will be our own brand-new space where we can thrive, collaborate and deliver the best for our clients. We’re looking forward to calling it home.”

Development 

The 12-storey development occupies a prominent freehold site with triple frontage overlooking the Tower of London and Tower Bridge.

It includes office accommodation with significant terracing, high quality public realm and sustainability credentials.

The development is being delivered by a joint venture between Benson Elliot, the European real estate private equity arm of MetLife Investment Management, and Hobart Capital Partners, which is acting as development manager.

James Jakeman, senior partner at Benson Elliot, said: “From the outset, our strategy was to create a best-in-class office scheme in EC3 while actively managing risk through shifting global capital market conditions.

”Achieving a full pre-let to Lockton ahead of completion is a defining outcome and reflects the strength of the underlying asset and positioning. With leasing secured, we are focused on disciplined execution through to delivery.”
