All TrustedHousesitters memberships are annual subscriptions. You pay once a year to arrange and enjoy as many sits as you like, safely and securely. 

Your membership is set to automatically renew so you can relax knowing your listing or profile will never unexpectedly expire. It also ensures you enjoy the same low price every year, even if the cost of membership increases. 

Of course, you can turn your auto-renewal off at anytime - just head to your membership settings.
