 Following George Trice's death in 1933, control of the business passed to his son, also called George. A coach hire and excursion business had been introduced in July 1931; this was split out into a new company, Tillingbourne Valley Coaches, which operated independently until 1955. From the early 1930s, until 1964, the service to Peaslake was run jointly with the London Passenger Transport Board; operation of the entire route was taken over in August 1964, but falling passenger numbers meant that the route was cut back in frequency a year later. A new livery of maroon and grey was introduced in 1964.
