Chestertons, which has 31 offices across London, said sales improved 6% to £46 million.
It said at the start of the first lockdown, when the housing market was effectively shut, the company quickly pivoted its service offering by offering virtual tours and remote valuations.
Restrictions in the sector eased in May and Chestertons said it was “well prepared for the surge of buyers and tenants that were clamouring to move once restrictions were lifted”.
The firm, led by Guy Gittins, increased revenue from its lettings division by 8% and from its sales division by 7%.
