Great Portland Estates (GPE), the £1.3bn central London real estate investment trust, saw new lettings in the last quarter come in at 9.1% over their estimated rental value in March. Chief executive Toby Courtauld said: “Healthy demand for our premium spaces continued, with more than £47m of lettings so far this financial year and a further £15m under offer… Whilst current global macro-economic conditions are unpredictable, we head into the final quarter with positive momentum. Prime occupational demand is well ahead of the long-term average, driving good interest across our on-site developments and fully managed offices.”
