The average size of London office deals is set to rocket by 57% this quarter, according to figures from EGi's research team.

Preliminary figures from EGI Research show that the average deal in the capital in Q2 totalled 8,250 sq ft compared with 5,230 sq ft in the first three months of the year.

Deals including Amazon taking 217, 000 sq ft at Axa's Sixty London and Bird and Bird committing to 138,000 sq ft at Great Portland Estate's New Fetter Lane helped push the average deal up by 57% to its highest level since Q1 2010.

"Q2 included three lettings over the 100,000 sq ft mark, so it looks like things might finally be on the up for the London office market," said Tom Pilkington, head of EGi's office research.

Overall, provisional take-up shows the quarter could end down on Q1's values with around 2.2m sq ft of space transacted currently accounted for, although this figure could rise. This is against just under 2.7m sq ft in the previous quarter.

The City core market is currently the only submarket to register a quarter-on-quarter rise in take-up. Provisional figures show take-up of about 992,000 sq ft this quarter against 650,000 sq ft in Q1.
