Try this one for size. The process is changing and I wouldn't trust the Government to assess household remotely to judge eligibility. The payment will also be £150 not £140 shown in the link.
Warm Home Discount Scheme (£140 cold weather payment) | Age UK
Payments start in October apparently but there is little to advise how you check whether the government has decided you're eligible or not.
According to Martin Lewis :
"
Under the new scheme, you should receive the rebate automatically
Under the current rules, unless you receive the guarantee credit element of pension credit, where you get the warm home discount automatically, you have to apply to your supplier to receive the warm home discount. And even then it's on a first come, first serve basis with suppliers also able to set their own eligibility criteria for those on certain benefits.
Under the new rules, those in receipt of the guarantee credit element of pension credit will still be guaranteed the warm home discount. Everyone else will receive a letter from October telling them that they will either receive the rebate automatically and therefore don't need to do anything, or that they may be eligible but need to call a dedicated helpline to provide further evidence of your eligibility.
If you think you're eligible but don't receive the letter in October, you can also contact a helpline, which will be available on
Gov.uk or via Citizens Advice. "
Apparently the new rules disbar circa 290,000 disability claimants but add 750,000 households on other benefits.
Hope this helps. I can't get this under any circumstances.
