Logic Board replacement on 2020 Macbook Air

Hi, have seen a few people asking similar questions and want to check on best course of action. Bought daughter a new macbook air to replace a stolen one back in October 2020. Laptop broke a month ago, initially thought it was a battery issue, but have now been told it is a logic board and could cost up to £500 to replace as the laptop is not under warranty. Have seen a few people saying Apple will replace for free under consumer rights laws. Any advise on best approach, don't want to have to pay out another £500 less than two years after buying it. Thanks.
