Worth reading in full. In short the Competition and Market Authority expects consumers to be offered a full refund where (amongst other situations) no service is provided by a business, for example they are prevented by Government public health measures, or a consumer is prevented from receiving services because government public health measures mean they are not allowed to use the services.
Note holiday homes in Scotland have been ordered by the Emergency Coronavirus legislation to close, if you need the legislation it is on the Scot Gov website.
If a business is not complying you can report them here:

Note the accommodation provider could at this point argue that should we be in Phase 3 by the first week July there will be nothing to prevent you from going and therefore no refund is appropriate. As soon as the Scottish Government covid route map indicates that we will not be in Phase 3 at that date (assuming accommodation opening hasn't been moved into Phase2) there will be no grounds for the accommodation provider not to provide you a full refund including any deposit.
If they say at this point you are unable to take that week due to Covid restrictions you are entitled to the full refund.
The Government and CMA was very slow to issue legal guidance so many business have been making policy up as best they could, but the above advice was issued at the end of April, so the accommodation providers in your case are either not following, or are ignorant.
Out of interest which company is it?
