The Consumer Rights Act 2015 is already on your side.
It states that goods should be of satisfactory quality, fit to do the job intended and last a reasonable length of time.
If you buy a new TV or washing machine and it breaks down within six months, you can take it straight back to the shop.
It’s up to them to prove that the appliance wasn’t faulty when you bought it.
You might even be legally allowed to return goods up to six years after you buy them.
But this depends on whether you’re able to prove that a fault was present when you bought it and that normal wear and tear wasn’t the cause of any problem.
