It is advisable for anyone coming to the cottage for a stay in the Borders to have the Scottish Test and Protect app installed on their smart phone. If the app requires you to input a Scottish address and/or postcode feel free to use the Half House cottage, Cappercleuch, Selkirk TD7 5LG.
Bear in mind that at present the English app does not cover Scotland and that you will require to choose which app is “active” as they will not automatically switch when you travel across the border. If you are travelling from England remember to activate the appropriate app when you return home.
