Did you buy Apple care with it? If so, you might be OK. Apple is not that strict with their AppleCare, if you are just a few weeks over or even a month or 2 over as long as you act quick. You can always blame the lockdown having delayed your plans etc.
To be fair, the consumer rights law applies to all retailers, so you can try throwing it at Dixons or is it now Currys PC World? But I think you'd have an uphill struggle with them.
