Challenging a bedroom tax decision - toolkit
Anyone affected will by now have received a letter from their council telling them about the decision. They have one month from the date of the letter to challenge the decision and this toolkit will help.
The kit consists of a standard letter and six arguments from which must be chosen the reason or reasons why a person thinks the decision is wrong. One or more of these arguments can be selected- whichever are
relevant to individual circumstances. The arguments are as follows:
Argument 1: If you or your partner need overnight care from someone who does not usually live with you and so need an extra room. (You may find it useful to read the factsheet on the Bedroom Tax before using this argument).
Argument 2: If an adult son or daughter, a parent or another adult needs overnight care from someone who does not usually live with you and so you need an extra room. (You may find it useful to read the factsheet on the Bedroom Tax before using this argument).
Argument 3: If you or your spouse or partner needs their own room
Argument 4: If a member of your household needs an extra room for other reasons
Argument 5: If your home has been specially adapted to meet the needs of a disabled person
Argument 6: If someone in the household has mental or physical health problems
