You do not need any qualifications, but you do need to be registered with Ofsted before you can look after children under the age of eight. To become a childminder, you will need to have patience and a sense of humour.ou may be able to get help with the costs of setting up your childminding business by applying for a childminder start-up grant if this is available in your area. To apply for a grant, contact the early years team at your local council. Approval of your registration to work as a childminder can take up to three months.
