Can anyone help me if you buy a record from Europe like Belgium would I have to pay more money even if it's a low cost  if anyone can help would be great

If you're buying direct from someone and they are okay to show a low value on the customs form then probably no. Depends if customs this end pick up on it - they would put a 20% charge on the declared value plus the postage cost. Royal Mail would then add £8.00 for handling the charge.

If you're buying through eBay or Discogs you would get 20% added at the point of purchase - that's 20% of the record value plus the postage cost. 

Thanks for your help

It's OK record hear just just a open it
