The RIBA has found that many UK practices rely too heavily on a single sector, or even a single client, putting them at risk should work in that sector suddenly dry up. These statistics are among the findings of the RIBA's annual Business Benchmarking Survey, the only mandatory survey of all chartered practices in the UK.
The benchmarking survey estimates that a maximum of 40% of a practice's income can safely come from a single sector, but it found that 60% of practices with 20-50 staff and 54% of practices with over 50 staff failed to meet this rule of thumb. Furthermore the survey found that 90% of practices with fewer than 20 staff relied on just a single client for over 40% of their income.
