Are you entitled to a severe mental impairment council tax discount?

Published: Thursday 30th November 17

A council tax discount is available for people with severe mental impairment and those that live with them. Wandsworth Council is urging residents who may be entitled to this discount to make a claim.

You can get a 25 per cent discount if you live with someone with a severe mental impairment and no other adults, or only adults who have also been disregarded for council tax purposes.

You can get a 100 per cent discount – which means you will pay no council tax at all – if you have a severe mental impairment and live alone.

Both of the following must apply for someone to qualify for a severe mental impairment (SMI) council tax discount:

1. They have been medically certified as being severely mentally impaired. For example, this may be the case if they have dementia, Parkinson's, severe learning difficulties or have had a stroke. It will depend on each individual’s case and the council will require a doctor to certify they are severely mentally impaired. 

2. They are entitled to at least one of a range of benefits including incapacity benefit, attendance allowance or severe disablement allowance. See the full list on the application form.

To apply download the form and either e-mail it to or print and post to Wandsworth Council, Council Tax Service, PO Box 65962, London, SW18 9HN.

Alternatively, you can get help to make an application from Citizens Advice Wandsworth. Go to for more details.
