Availability has edged back up to 1.6m sq ft at the end of Q1 2026, due primarily to the increase in grade A space, which has risen to 442,000 sq ft. Grade A supply has been boosted by the new development at British Land’s Canada Water scheme, where the 126,000 sq ft Three Deals Porter building completed in December 2025. The overall availability rate now stands at 7.7%.
