My back door frame and part of the step/sill is rotten and is in need of fixing, but I'm no chippy and I've no idea how to approach this problem. The door itself is steel skin over a wooden frame (I believe).

rotten door frame and sill".
Tom, I think you have pretty much taken a photo of my door. I am following the advice in this posting

Having obtained a new sill from a local builders merchant. I don't think the door material is relevant (as the door is not rotten) but I have water leaking round the DG unit in the door and cant see how to remove the DG unit to re seal it.
The only slight problem I had was that the sill was attached to the door posts by screws inserted from below (ie before the door was installed), on one side this was no problem as the sill was sufficiently rotten, the other side required a bit of chiselling to split the wood and so remove the remains of the sill from the door post.
Chop out offending section and an inch more (multimaster style tools are good here[1])
I would usually cut across the frame at a 45 degree angle (i.e. to make a scarf joint). Cut new (hard)wood section to fit, Counter drill a little way into the new bit, then drill through with a smaller drill. Add liberal quantity of waterproof adhesive (epoxy if the gap is not perfect) and screw through the new bit into the existing. Add a wood plug to cover the screw or fill with a two part wood filler or car body filler. Once in and set, fill (with two part filler again), shape and sand to fit before repainting.
Indeed . The cost benefit of a complicated carpentry repair verus simple replacement is rubbish. either patch the rotten bit by the quickest simplest method, which is body filler - and that wont rot, either - or replace the whole shebang.
Its not worth dong a 'proper' repair job on wood unless its got some value over and above the raw cost of replacing it. Listed building or fine joinery and the like.
Looking at the OPs p[hoto says to me 'man on a limited budget, and probably with limited carpentry skills or he would have fixed this already';
Hence car body filler which I have used on a similar sort of property in a similar stare to effect a repair that was still perfectly ok when I left the (rented) property.
OP here. Your assumptions are indeed correct. I'm not very good at carpentr y and don't want to have to pay 400 quid or have the hassle of finding a de cent installer to fit a new uPVC door. I'll give the car body filler a go a s it's worth a punt for 20 quid.
Would you use car body filler to repair the softwood door jamb as well as t he hardwood step?

hardwood step?
If you are going down that road I would definitely consider treating the ends of the wood (after you have removed as much rot as you can) with something similar to this before you start filling.
Ok, if you're going that route, first find a cheap supplier for the body filler. E.g. you won't get much for £20 in Halfords. You can create straight lines and flat surfaces with bits of ply/hardboard as long as you remember to smear with vaseline to act as a release agent. The suggestion (John Rumm?) of setting new wood into 2 part filler is a good one because a0 it will probably cost less and b) your carpentry skills can be non-existent. This is more like sculpture :-)

anything thats painted but with the following caveats
- you must get the wood dry (hair drier or wait for a series of fine days)
- you must remove anything that's rotten
- putting screws or nails in will give it something to bond to.
- you can use any lumps of anything to bulk it out...stones gravel or blocks of wood
- you can mould it using polythene sheet and a bit of wood nailed down to keep it there while it sets
