It started off with little black spots and leaf curl. Checked for aphids and sprayed with a little soapy water it now looks like the photo below...is it aphids, the soapy water or something else? Thanks in advance.

Has it been caught by the frost maybe?

Either the compost is alkaline and is locking up the Iron / Manganese, or the Iron and manganese have been depleted.
I would repot into fresh compost just about every year and feed with a complete feed (something with sequestered Iron & Manganese in it & follow the instructions)
You should notice a subtle difference in leaf colour in a few weeks.
But you will not get rid of the black/brown spots until that leaf drops off.

Can you tell me what root stock it is on, what variety it is, did it produce any fruit buds/blossom this season?

There are very few, if any Aphids.
There maybe a touch of windburn / frosting but the losing of some colour from the leaves suggests to me that it is not being able to take up Iron and Manganese & any frost /wind damage is secondary to the main problem.
That's what I reckon anyway.
P.S Is it possible to take a full length photograph also a close up of a couple of the leaves?

Thank you both...we did have a late frost here so could be that?

Not sure of the rootstock as the label doesn't say. (It was bought from Morries) The variety is Harvest Green and it has had no blossom on it whatsoever so far this year and most of the leaves are now going this way. It's quite small but was sold as a patio pear. Have attached photos as requested fishpond. The tree has been in the same pot for a couple of years now so maybe it needs to be repotted.

Repot it with good john innes compost and remember to feed and water throughout the year.

Thanks fishpond, will get the pot and compost today! Fingers crossed.

It might also be wind damage. I've found that young expanding pear tree leaves are quite susceptible to this. I guess their cuticles aren't very tough.
