Handling your complaint

Stage one

Once we have received your complaint, we will aim to provide you with an initial response within two working days to acknowledge and advise you of its status. We aim to resolve our complaints within fifteen working days. However, depending on the nature of your complaint we may need to discuss the issue with other departments or companies to resolve the matter and will therefore keep you informed throughout the process.

When we have addressed the issue, we will contact you and let you know the outcome including:

  • An explanation of what may have gone wrong
  • Our actions to address the complaint

Stage two

If you are dissatisfied with our response, you can write to our Head of Property & Estates, Complaints, Cornerstone, Hive 2, 1530 Arlington Business Park, Theale, Berkshire, RG7 4SA. Please include full details and why you remain dissatisfied.

Your complaint will be investigated by a senior member of staff within the relevant business area and we will send you a further response within fifteen working days.
Nothing in this policy affects your legal rights.
