There's nothing wrong with Radeon btw, I use both vendors, so if you want to stick to budget go 6800XT and it's got 16Gb vram.
But if you're wanting to stick to NV, I wouldn't buy one of those cheaper 70s posted above for the sake of saving £20, in comparison to the 4070FE-they look junk!
I'd turn on DLSS/FSR and either save up more for 4070FE for no hassle warranty or hold out for a 4070 with a 3yr warranty to drop in price, preferably Zotac for the UK RMA centre and 5 yr warranty if you register with Zotac.
They're all valid vendors which have been in the game for decades. Much like myself, their biggest issue is that they offer short term warranties by comparison to the likes of Zotac and Gigabyte. There's no such thing as a "good brand" and it's a mindset people need to let go of.
Every company releases good and bad, you do your research and buy on a case by case. Generally speaking you gain little to nothing by spending a premium on the same processor despite the bells and whistles or advertising.
Would I spend more for UK based warranty? Absolutely, but only within reason and the store you buy from is responsible for the first year regardless.
