A:Answer Hi Jonnykerb.
Good question. Ring does not recommend altering the plug for the Ring Spotlight Cam Wired (Plug-In), and doing so will void the warranty on the device. If you require a G-type, three-prong plug, we would suggest that you order the proper version from our website, https://en-uk.ring.com/, or purchase from a local authorized retailer in the United Kingdom.
Here are the step-by-step installation instructions for the plug-in device: https://support.help.ring.com/hc/en-gb/articles/9670720575380-Installing-your-Spotlight-Cam-Plus-Plug-In.
We invite you to reach out to our Community if any additional information is needed regarding your question.

All the best,
Nicole from Ring.
