Finance director Matthew Thorne said that a replacement would not be made until fresh guidance on the make-up of corporate boards was issued next year.
An appointment would then be made in the run-up to the company's annual general meeting, this time next year.
The news emerged after McCarthy & Stone announced a 54% increase in annual pre-tax profit, breaking through the £100m barrier.
The firm made £116m in the 12 months to 31 August, from a turnover of £255.1m. Turnover in 2002 was £188.1m. The results mark a decade of continuous growth at McCarthy & Stone.
