What qualifications do I need to be a personal trainer in the UK?

A Level 3 Diploma in Personal Training is the recognised standard that gyms and insurers expect. Specialist populations, such as pre and postnatal clients, need additional qualifications.

How much does it cost to start a personal training business?

If you are already qualified, often under £700. Insurance from around £60. Company formation about £63 all in. A bookable one page website. The qualification itself is the biggest cost for newcomers.

Can I run a PT business as a sole trader?

Yes, and many do. Trainers building a brand beyond their own hours tend to incorporate, so the business name is protected and separable from them. Online programmes and employed coaches push the same way.
