Check the contract you have with your tenant. It may have a clause in there stating that they need to oblige to any viewings of their home with reasonable notice.
However, if there is no such clause in their contract, then a tenant can reasonably refuse a viewing if it is causing significant disruption to their life. This can be tricky as it is up to the tenant to determine what they consider to be a significant disruption.
Cash buyer property companies like We Buy Any Home can buy your home without conducting any viewings or disturbing your tenants.
