Hello my name is ***** ***** I will help you with this.
Wont the neighbour do anything about it? If not, why not do you know?
You need to get a Solicitor to write and ask that he fixes it or say you will seek a Court or making him
If he refuses you have 2 options, do the work and seek a small claim for the cost.
Or seek a Court order making him do it.
If you are seeking a Court order making him then you need to complete forms N208:
The Court will list it and decide whether to make an order.
If you do the work and want to claim the money back you can do this online at: www.moneyclaim.gov.uk
Can I clarify anything for you about this today please?
All the best
