The person organising your appointment will send you a personalised link either by text, email or letter.
You will need a computer, tablet or phone with a webcam, speakers and microphone. Most modern phones, tablets and laptops now have these built in. You will also need the latest version of either Google Chrome, Microsoft Edge or Apple Safari, which are free to download.
Simply click on the link or type it into the address bar of the browser, then follow the instructions. Please make sure you select 'allow' when the browser asks for permission to use your camera and microphone as these are needed to make the call.
