What are some name brands of baby food in the UK?

Hi there, I'm going to be moving to the UK with my husband as he's an English citizen and was wondering what are some of the UK's name brands of baby food? Are there any differences to say US Gerber or Beech Nut brands that the US has? And are your stages the same as ours or slightly different, ie: stage 2 in America starts from about 6 months, stage 3 starts at 8 that type of thing. Thanks so much x
