Can I put a 2 m fence at the front of my house?

Only if it isn't next to a road used by vehicles or its footpath. Along the pavement the limit is 1 m.

What if the ground is higher on my neighbour's side?

Height is measured from the ground where the fence stands. On sloping or stepped ground, measure from the highest adjoining point to be safe.

Where	Max height	Listed building
Back and side boundaries	2 m	Not permitted
Next to a road used by vehicles	1 m	Not permitted
Replacing an existing, taller fence	Same height	Not permitted

Maximum 2 m above ground level.
Maximum 1 m where it adjoins a highway used by vehicles, or its footway.
Replacing or repairing an existing fence is fine up to its current height, even if that's over the limit.
Trellis on top of a fence counts towards the height.
