Trademark Concern: Can I Use a Brand Name That Already Exists?

Hey everyone,

I’m currently in the process of submitting a trademark application for our brand, which specialises in hand tools. However, I recently found that there’s already a brand with the same name, but they sell paints – a completely different product category.

If I secure a pending or approved trademark in the UK, would Amazon still reject my application for Brand Registry because of the existing brand with a similar name in a different industry?

I’d really appreciate any insights or experiences from those who’ve faced similar situations. Thanks in advance.
