What does it involve?

Given that they only operate during the school terms these are ideal franchises if you have a family or are looking for a second income that isn't a full time job. You need to be aware, though, that while they only operate during school hours, you will need to do some preparation work out of this time.

Monique Brennan of Tumble Tots, Holmfirth puts a limit on the amount of time she works in the evenings but still finds she has to spend least an hour and a half answering calls and doing paperwork.

Days work out well for looking after her own children, though, as classes only run when they are at school - 9.00am to 3.00pm. This equates to about four classes a day for her and staff.

Primary Books franchisee John Ward took early retirement from his work in adult education. He was attracted by the franchise because it was continuing in a field he was familiar with and it seemed relaxed.

"On days where I just have appointments in schools, I might have two to three during school hours which gives me time to come home in between. Then a book fair will take a whole day," he says.

Franchisees will always have dedicated admin days and meetings days in the week. Without the former, there is no time to stock and order in for the latter - a certain amount of stock needs to be kept in at all times.

A typical day with all these franchises may mean dealing with tired and frustrated parents and teachers - as well as children. So you need to be prepared to enjoy what you do. Equally, all franchisees spoke of how much they enjoyed the work and how satisfying it ultimately was.
