Step 1: Get yourself a VPN. This can be with any company that offers UK servers. I personally recommend PureVPN. You can get 1 year for only $1.99 per month.
No VPN. No Free Games. Simple as that.
Step 2: Download their app to your TV, Laptop or Smartphone. Alternatively use their apps for android boxes, Fire TV, Roku or MiBox.
Step 3: Choose a UK Server. Connect to this.
Step 4: Download the ITV app or visit ITV player website on your device.
Step 5: When creating your account choose a post code in London.
SW5 0TH is a good one.
Step 6: Start watching your games for free.
