Nice you decided to join the fun. I think the most important tool in the shop is a really good table saw. Get one that takes a dado stack or at least has a long enough arbor to mount a couple of blades to make a wider cut. It is tempting to get other tools first, but as soon as you get a table saw, you will start to see better, more precise results. In the UK, tool models are different and metric, so we generally defer to our British friends to make specific recommendations.
First power tools to me should include a big bench mounted drill press, a really accurate miter gauge (incra), a decent 2plus hp router in a home made table. A decent quality circular saw for breaking down sheets of ply, including very high quality blades (for the table saw too). Freud makes really nice premium saw blades and a wonderful variety of router bits. You can use the circ saw with a speed square to cut long lumber to shorter lengths, then use the table saw for precise lengths. A chop saw can be used for that, but mine gets very little use anymore and it's incredibly messy.
A block plane properly sharpened is a really handy thing to learn to use, and more and more often I reach for the Japanese Dozuki pull saw. And clamps, lots of clamps. Especially F clamps, mostly the 10/12 inch sizes but a few pairs of longer ones, 24 inch and 36 inches. Pipe clamps are cheap and versatile for really wide projects.
I was lucky in having peak earning years as I was building up my shop, but it took years to accumulate all the tools I love to use, so start by buying the very best quality basic tools, you won't regret it.
Attached is a pdf of the 18 plus things that helped me accelerate my learning curve, including some mistakes I made as I got going. Perhaps it will save you some disappointments. It is based on American tools, but much applies to UK, just different tool models. It is long, but has lots of illustrations.
The more I do, the less I accomplish.
