There is a multitude of environments where coaches are found such as the corporate sector, long-term condition management, community and family environments, education establishments, young people’s issues, beauty and appearance, baby-boomer market, weight management, lifestyle, elder-care, healthcare organizations, and the fitness industry. You can take your coaching skills and knowledge back into your PAYE job or a better one. You can be an evening (coaching) entrepreneur and keep your day job. Or you might start up or enhance your own business.
Padding this answer out (I could go on forever here), you can deliver 1:1 coaching/group coaching on or off-line, create passive income products, enhance a consultancy or deliver training.
