You may not think so but it is the case.I don't think that's it in this case.
The manufacturers warranty is in addition to your legal rights. Your legal rights are not a warranty but protection against faulty goods.Sony web pages even now say standard warranty is 12 months, above that only if you buy additional cover ..
Retailers make lots of money selling unnecessary extended warranties to an unsuspecting public.That corresponds to my hazy memory from when we bought in in 2017. Currys was offering a two year warranty, but was £100 more expensive and I didn't think it worth the extra for one more year. Furthermore if I use their Warranty Checker and put in the correct model but slightly different serial number it says the warranty expired in 2018 - 12 months. Put in my serial number and it says "Your warranty end date is: 14/09/2022" - five years.

Excellent outcome.I'm pretty sure this is something to do with my fault report. During the correspondence they wanted to see a proper invoice from the retailer, and shortly after I sent that I received an email titled "The service contract for your Sony product has been updated." and including a PDF certificate with start and end date, terms and conditions etc.
