I've had a look at your site & you have
- http://rogerlapin.co.uk/ - Status code 301 - redirect URL to https://rogerlapin.co.uk/
- https://rogerlapin.co.uk/ - Status code 301 - **redirect URL **https://www.rogerlapin.co.uk/
- https://www.rogerlapin.co.uk/ - Status code 200
You're using number 3 (above) as your URL, so, my suggestion is to set both the redirect URLs for 1 & 2 (above) to https://www.rogerlapin.co.uk/ instead of the chain you currently appear to have in place.
