Razer Blade 15 Battery Swollen and no warranty

Suddenly the trackpad of my Razer Blade 15 Base Model (2019) stopped clicking and after a web search I found out that this could be due to a batter swelling. Many complaints about it over the web. This was exactly what I found when looked at the battery. Only 1 year and a half of use. Where can I find a replacement battery (living in the UK)? How can Razer help me with that? I have had such a great experience with the laptop until discovered the very unfortunate problem.
