You won't have your boundaries measured as such, I used to work in Property Law for a number of years, your boundaries will be clearly marked on your Title Deeds (if you own the property that is) if you dont own it then the Council will hold these Deeds. You can certainly apply for a copy of your Deeds from the HM Land Registry or your solicitor can do that for you. Hope this helps.
P.S If you are experiencing a boundary dispute, I suggest you see a solicitor anyway and they will automatically apply for a copy of the Title Deed.
