After-school nanny needed for 2 children in UK

I'm looking for a reliable after-school nanny to collect my two kids from school, help with homework, prepare a light dinner, and keep them safe until I get home. The role is weekdays during term time, roughly 3-4 days per week. Kids are 6 and 9, so activities should be age-appropriate and engaging. We prefer native English speaker with experience in childcare, first aid a plus, and the ability to drive would be ideal but not required. Please mention your hourly rate, availability, and any relevant certifications. The family is based in a quiet, family-friendly neighborhood with a parks nearby for after-school play.
