Disability benefits

Hello all,

I've have a few canvassing calls lately regarding a free boiler if me or anyone I'm our household is claiming benefits, not sure if this is the latest scam or if its genuine?

My father-in-law lives with us, hi is 67 and he had a stroke 4 years ago and receives the higher rate disability payments

Can anyone tell me what, if anything we would be entitled to, boiler, cavity wall etc. and any other benefits we might be missing out on?

Many thanks

Grant
