Up to you, but my advice would be to change that order in terms of Prop B/Equity/Trusts (3 of the hardest core units).
I think it's best to have done Property B before Equity and Equity before trusts, however you could do Property B with Equity then Trusts, or Property B then Equity with Trusts. Many people do either of the latter combinations, but I think doing Property B after Equity (and alongside trusts) is kind of the wrong order. I'd be inclined to go for Property B 1st Sem. That leaves you with the obvious problem of having a disastrous Sem 2 with Equity/Trusts/Corps...then again, even with Prop B and not Equity that's a very hard semester.
Solution: Swap Property B for Equity, but push either Trusts or Corps into S1 2015, and take Civil Procedure over the summer (or alternatively, take an elective over the summer). Equity & Trusts and 1 Arts unit will be a lot more manageable without having corps added on to it. Plus, even though it in some ways make sense to do Equity before Trusts, you can do them at the same time, and there is a bit of overlap, so it's useful in that sense to do them in the same semester.
I would also consider swapping Admin for your S2 2015 elective. That thereby avoids doing 3 core law units in the 1st semester too. The electives are often easier than the cores, although in some cases they are just as hard/harder, it depends.
Edit: that all sounds rather complicated, but it would look something like:
S1 4th year: Prop B, Consti, 1 Arts Unit, 1 Law Elective
S2 4th year: Equity, Trusts, 1 Arts Unit
Summer (Civil, or an elective, e.g. Neg/Med which can be done in 1 week, in which case you could put civil in 1st sem 4th yr)
S1 5th year: Ethics, Corps, 2 electives
S2 5th year: Evidence, 1 arts unit, Admin
