Most of us may not be aware of this. There is bereavement support.

Follow these guidelines from UK government as a starting point…

We thought it may help someone somewhere in need of help.

(1) There is a bereavement support of £2,500 lumpsum onetime payment from the government plus a monthly payment of £100 per month for 18 months, so a total of £4,300 by the govt through the DWP and this is quite easy to avail and available to mostly all qualifying people that too in less than 48 hours.
To avail this, either one can file the application online or the faster route is just call the bereavement support line 08007310139 or 08001214433 option 3. Only information required is the name, DOB, N.I. number, date of death, address, bank sort code and account number, thatsall and within 20 minutes the application will be completed and filed by the call center agent and the money will be in the account in less than 24 to 48 hours, if your application is qualified.

(2) There is also a funeral expenses reimbursement program, that is up to 60% of the actual cost of funeral that you spend will be reimbursed for which you need all supporting documents including the invoice from funereal directors. However, in order to qualify for this, either the deceased or their nearest kin (spouse, any of the surving children etc) has to be on some kind of benefit such as universal credit, social housing, unemployment, child benefit and so on). To avail this, one needs to call 08001214433 or 08009172222 or 08007310139 and they will guide it through.
