Get a reference for the enforcement notice, then get on to your local planning authority (District council if you have one) and ask them to check what the notice refers to. It may well be that an action was started, then when they realised you had consent for the work you'd done, never bothered to deliver it. It might just be that it's not been cancelled. It may also be from before you owned the house, so have a think about any work that might have been done prior to you buying (if this is the case your original solicitor is at fault for not picking it up).ourkid said:
Thinking about it, just ring your planning enforcement team, and give your address, they'll be able to access the record quickly enough.
Let us know how you get on, I'll help more if i can.

Edit : where do you live?
Edit2 : to answer your initial question, and enforcement notice is served when something has been done which doesn't comply with a planning consent, hasn't got planning consent when it needs it. An enforcement order is then used to order a landowner to undo the offending work. You can appeal against them, but it takes time and will cost you some legal/consultancy fees, and time is not on your side at the mo.
