Have a look at the house deeds if you own the house or check with the council otherwise. Height and type of fence is usually specified. If it isn't, you can erect a new one up to 6ft high. Looking at the existing fences, the one on the left and at the back belong to you, the one on the right belongs to your neighbour (where the posts are on your side, that is generally your fence.) On the fences which are your responsibility, you could also attach tall reed screening similar to this:
If you aren't allowed to erect anything like that, then tall shrubs or hedging is all you can do.
