Client complaints procedure

At all times, we aim to provide our clients with a professional service of the highest quality.

Any client who is unhappy with any aspect of our service is entitled to complain. We treat all complaints seriously and are committed to investigating them promptly, fairly and free of charge.

If you have any complaint, including a complaint about your bill, you should raise it in the first instance with your relationship partner or the partner responsible for the relevant matter. If that is felt to be inappropriate, or if you feel that the response of the relationship partner or the partner responsible for the matter is inadequate, you can write to Julia Adams, our General Counsel, at One Bunhill Row, London EC1Y 8YY or by using the [email protected] email address.

We expect to resolve any problem to your satisfaction.

You may also be able to ask the Legal Ombudsman (“LeO”) to help you to resolve your complaint. Before accepting a complaint for investigation, LeO will check that you have tried to resolve your complaint with us first. If you have, then you must take your complaint to LeO:

  • within six months of receiving a final response to your complaint; and
  • no more than one year from the date of act/omission; or
  • no more than one year from when you should reasonably have known there was cause for complaint.

You can contact LeO by telephone on 0300 555 0333, (and if you are based outside the UK you can telephone on +44 121 245 3050); by email at [email protected]; or by post at Legal Ombudsman, PO Box 6167, Slough, SL1 0EH.

LeO will only consider your complaint if, at the time you raised your complaint with Slaughter and May, you were:

  • an individual;
  • a micro-enterprise;
  • a charity that had an annual income net of tax of less than £1,000,000 (one million pounds sterling);
  • a club, association or organisation whose affairs are managed by its members, a committee or a committee of its members that had an annual income of less than £1,000,000 (one million pounds sterling); or
  • a trustee of a trust that had an asset value of less than £1,000,000 (one million pounds sterling).

LeO may also consider complaints made by a personal representative or beneficiary of the estate of an individual who raised a complaint with us, but had not referred it to the LeO, before they died.

If your complaint concerns acts or omissions outside England and Wales, LeO may dismiss your complaint if the circumstances do not have sufficient connection with England and Wales.

If your complaint relates to your bill, you may also be able to apply to court for an assessment of the bill under Part III of the Solicitors Act 1974.

Other complaints

If you are not a client but you nevertheless have a complaint in relation to our provision of legal services, please raise the matter with Julia Adams, our General Counsel. You can do this by writing to her at One Bunhill Row, London EC1Y 8YY or by using the [email protected] email address.

We will deal with any such complaint promptly, fairly and free of charge.
