I am new to the gardening world .. I desperately need help on my pear tree? Has this got some sort of disease? Do I need to cut it all down ? And this is also attracting a lot of ants.. please can you advise .. many thanks
Starting with fruit trees is a big challenge for new gardeners. Fruit trees are best grown with a regular spraying schedule for pests and disease. They often need pruning and fertilizing besides adequate water. Not the easiest plants to grow for a beginner, so don't be too discouraged.
It looks like your tree has several things going on. The ants are attracted to honeydew produced by aphids, scale or pear psylla. Aphids are on the leaves and scale are usually on stems or trunks. Pear psylla looks like cicadas. Honeydew can cause sooty mold. I think I see galls, too. Here is information that should help:

I have a pear tree which is approx 5 years old. It has never borne fruit. The leaves are green but curl up quite quickly and some go brown. I cannot see any places where anything is oozing out of the bark. There are some whitish marks on the branches. Photos attached. I also have similar problems with an apple tree which is roughly 3m from the pear and I will send details in a separate message. Can you please give me some advice on how to deal with this problem. All answers considered including cutting it down and starting again. Regards John R. Symonds email: john.symonds2603@btinternet.com
This is one of many soil born illnesses. Probably Phytopthora or Verticillium. These two will cause problems with many tree species.

Pear/ fruit itself grows a little bigger then a cherry and its completely black and falls off
Do the tree branches and leaves also have black looking lesions, like it was in a fire? If so, your tree may have fire blight. If not, check out the information for pear scab.

The first thing to note is that my pear trees are being grown outside of their normal growing region. I actually managed to grow them from seed in The Bahamas. In the Bahamas we have Tropical weather. The temperature Is usually in the lower to mid 90s and so i try to water when i see the soil is dry. Originally it had nice green foliage and then the leaves started growing smaller and their color changed from a nice dark green to a greenish-brownish color. I have two other Pear trees and their leaves Are not growing like how this one is growing. Please Help me.
Unfortunately, this may be a case of too much water! This looks to be the start of an infection, and suffocated roots.
Make sure to let the soil dry, thoroughly, down to about 3 or 4 inches between waterings.
It will, likely, never flower, since it will never have enough chilling hours to do so, unfortunately. But, it can make for a nice foliage tree with some care.

ut the leaves are in various degrees of black spot development. Please identify and advise how to cure this problem short of chopping the wretched tree down. Many thanks Phil
This appears to be Pear leaf blight (Fabraea maculata). This will require, both, treatment and prevention for the future. Here is an article that will get you started:
