The Veterans Welfare Service (VWS) provides professional help and advice to veterans, their families and dependants, as well as those supporting veterans.
They help veterans complete PIP and attendance allowance forms as well as PIP reviews and support clients to apply for war pensions to compensate for any injury, illness or death that occurred in service before 6/4/05.
If you need help, contact the welfare centre closest to where you live, or contact the Ministry of Defence.
