No, but maybe!
There is no "official" minimum number of hours for Visits.
Many people using Kynd organise Visits for as brief as 1 hour periods.
It all depends on what you and your Support Workers mutually agree.
As a rule of thumb, many Support Workers prefer at least 2 hour visits.
This helps them given any travel, traffic and parking time.
Wherever possible, it's best to build a team who lives fairly close to you!
You can send requests. Support Workers will accept if suitable for them.
