What has happened?

Two London councils have been affected by a cyber security incident. These councils are:

• Westminster City Council
• Royal Borough of Kensington and Chelsea

The affected councils currently have limited access to their IT systems. Council staff are working to restore full access to these systems. Some council services may be disrupted while this work takes place.

I have a new complaint

We are in contact with Westminster City Council and Royal Borough of Kensington and Chelsea and will provide a further update in early February. We are not curently taking complaints about these councils.

Is Hammersmith and Fulham also affected?

We are able to take complaints about Hammersmith and Fulham as its systems have not been impacted by the cyber incident.

I am in need of urgent help

If you have an emergency or urgent need for council services, contact your council directly using their published emergency contact numbers. See below for their website deails.

I already have a complaint with the Ombudsman

If you have already submitted a complaint to us about one of these councils, we will continue to progress your complaint as far as possible.
