Issue with padding/margin using Woocommerce template

Hello,

I created a template which works fine on single products however on all pages which have product variations, I am getting an issue with the padding/margin at the top of the page.

Here is a live page with the issue:
https://www.thermosphereheatingstore.com/product/comfortzone-150w-electric-underfloor-heating-mat/

And here is one without the issue:
https://www.thermosphereheatingstore.com/product/thermotouch-programmable-wifi-glass-thermostat/

(please note this isn’t optimised properly for mobile yet)

Any help is hugely appreciated!!

Thank you
