The aim of the national fuel scheme is to assist householders who are on long-term social welfare or health board payments and who are unable to provide for their own heating needs. A payment of £5 per week – £8 per week in smokeless zones – is paid to eligible households for 26 weeks from mid-October to mid-April, regardless of the temperature. As a consequence, there may be a small number of occasions when the allowance is not paid even though temperatures are unseasonably low and equally, the allowance is paid at times when temperatures are above the seasonal norm.
