My very first suggestion is to not immediately go out, spend a fortune on gear that's been recommended only to consign half of it to either eBay or storage!
What works for us might not work for you (we're all different, after all).
Personally, I always recommend going with the basic categories rather than specific items:
1) Shelter: do you want to use a tent or a tarp? Your choice, they each have pros and cons... so make that decision and investigate the options on your chosen path
2) Fire: do you want to go more old-school and only use natural tinders you collect in the great outdoors, or do you want to pre-prepare artificial tinder such as cotton balls with vaseline? Either way, you should always have more than one way to start a fire, and a firesteel/ferrorod is pretty-much a universal item in that area. Again, there are options when it comes to which firesteel/ferrorod to get... so that's an area you can research, though a cheap one isn't going to be a pain if you decide you prefer some expensive fancy one.
3) Sleep: do you want to use a down sleeping bag or a synthetic [they each have pros and cons]? Figure that out and research the options there. Try a night with minimal gear to determine whether you want to add a Thermarest [self-inflating mat] to your kit. If you buy it and don't need it, it's just a waste! Did you choose a tarp for shelter? If so, you might want to decide whether you want to sleep in a hammock instead of on the floor... so many choices!
4) Cook kit: do you want a lesser-diameter deeper cook pot or a wider-diameter shallower one? Do you want aluminium, stainless or titanium? They each have pros and cons [titanium's big con being price]. Similarly with cutlery... though you probably would be best starting off with a couple of cheap plastic Sporks and making your long-term choices over time!
5) Water: Do you want to use a solid canteen, or would you rather carry a flexible bladder? Again, they each have their pros and cons... so I recommend a bit of research before making a decision. That said, if you already have or can easily get hold of either one cheaply enough, you can always work it out with some trial and error!
6) Tools: You are almost certainly going to need a knife. As others have already suggested, you'll very likely be best off starting with a cheap Mora Clipper (they're about £10, very robust and capable). Do you want to use an axe? If you're not already proficient with one, I'd advise against it... and suggest that you seek advice and instruction from someone more experienced with one before choosing so much as the type of axe you want to get. Would you rather use a saw (or have a saw as well, given that they can process wood in some situations more efficiently than an axe)? If so, there are plenty of exceptionally good folding saws on the market to choose from.
7) Carriage: How do you want to carry your gear? There are so many rucksacks out there, but ultimately the choices you make on the above will have significant bearing on which rucksacks are best suited to you and your gear. Some people try to cram everything into as small and light a pack as they can, while others buy a bigger pack to provide more room for organization (I'm the latter, just so you know). There again, you could always buy a cheap Bergen and try it out to see what works best for you!
Ultimately, your kit is a personal choice that will forever evolve the more you use it. Rather than having a bunch of brand and product names dumped on you, I really do genuinely believe that you should examine the options for each category and make your own decisions.
Also, I recommend starting at the lower price-point and working your way up! I've heard tales of people spending £300+ on a pair of Wellingtons... which I think is utterly stupid!
Bushcraft can be done on the cheap, and that's where people should start (again, my opinion). If you end up deciding that it just isn't for you, then at least you haven't invested a fool's fortune already.
