    When generating the link's HTML, you can obtain it by specifying the name of the iframe in target.

    So add a name attribute to your iframe like this: 

    <iframe id="iframe" name="iframe" src="mylink" width="100%" height="400"></iframe>

    Then add a target attribute. 

    document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '" target="iframe">' + link[intlinkIndex] + '</a>';
    function writeLink() {
    if (intlinkIndex >= link.length) {
      let btn = document.getElementById('btn');
      btn.style.display = 'none';
      mylink.style.display = 'none';
    }
    document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '">' + link[intlinkIndex] + '</a>';
    document.getElementById('iframe').src = link[intlinkIndex];
    intlinkIndex++;
  }

    Complete source code

    <!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.footer {
   position: fixed;
   left: 0;
   bottom: 0;
   width: 100%;
   background-color: red;
   color: white;
   text-align: center;
}
</style>

<script>
let link = new Array()
link[0] = "https://www.clc-uk.org.uk/cms/cms.jsp?menu_id=26131&postcode=AL3+8QE&distance=20"
link[1] = "https://www.clc-uk.org.uk/cms/cms.jsp?menu_id=26131&postcode=AL5+3NG&distance=20"
link[2] = "https://www.clc-uk.org.uk/cms/cms.jsp?menu_id=26131&postcode=AL4+3NS&distance=20"

let intlinkIndex = 0;

function writeLink() {
  if (intlinkIndex >= link.length) {
    let btn = document.getElementById('btn');
    btn.style.display = 'none';
    mylink.style.display = 'none';
  }
    document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '">' + link[intlinkIndex] + '</a>';
    document.getElementById('iframe').src = link[intlinkIndex];
    intlinkIndex++;
}
</script>
