You can get Bereavement Support Payments from the government. This is not a means tested payment, and is open to people whose husband, wife or civil partner died in the last 21 months, provided that the late partner paid National Insurance contributions for at least 25 weeks in one tax year, or if they died because of a work-related disease or accident. You will get £2,500 as an initial payment, and £100 a month.
Claiming within 3 months of the death means that you will get the full amount, but you can claim up to 21 months after their death. You can apply online, by phone or by post.
I was widowed at 50 when Tim, who I expected would be my happy-ever-after following a marriage break-up, died suddenly from heart failure linked to his type 2 diabetes. Though we'd known each other since our early 20s, we'd been married less than ten years.
