Making alterations and improvements to your property

If your property was originally bought from the council or us (even if this was before you bought it), you’ll need to request our written permission to make alterations or improvements that will change the appearance or structure of your property (including changes you have made in the past). This includes things like:

  • Replacing doors and windows
  • Installing a driveway
  • Building or removing any walls
  • Adding extensions, porches and conservatories
  • Painting or cladding the outside walls

(If you rent your property from us please visit the DIY and making improvements page in the tenants section.)

How to make your request

To make a request please email or write to us and include the following:

  • Your full name, address, email address and phone number(s)
  • A description of what you want to do
  • Any plans, drawings and specifications

You must request permission before you start the work.


The charge for permission is £100 per request, unless it's a large change (see below), in which case it's £300.

If you only make the request after carrying out the work the charge is £250, or £450 for large changes.

Make a payment

Large changes

Includes things like:

  • Erecting any solid-built building like a new house, garage or outbuilding

  • Any form of extension - front, back, side, or porch

  • Paving or concreting an area of garden (such as for parking)

  • Loft conversion

  • Internal structural changes like removing or creating solid internal walls

What we’ll do and when

Once we’ve received your request and payment, we’ll respond in 10 working days.

You’ll receive a letter from us confirming or declining permission for the alteration.
