You may also be entitled to a Disabled Facilities Grant if you need to adapt your home to make changes for a disabled child. This grant can help pay for adaptations such as building safe play areas, installing a stairlift, widening doors or adapting heating or light controls.
If a local authority needs assessment has concluded that you need this equipment, it should be provided free of charge. Minor adaptations costing £1,000 or less – which includes the cost of buying and fitting the adaptation – are also provided free of charge. Councils can make a charge for minor adaptations that cost more than £1,000 to provide.
Larger, more expensive items may be classed as adaptations and will be the responsibility of the housing department and provided through Disabled Facilities Grants.
