Cancer and the associated treatment can make people more likely to feel the cold – weight and hair loss, a lack of appetite, reduced energy levels and circulation problems can all contribute to the problem.

This means higher energy bills. One in five (21%) see their yearly energy bill increase by almost £200. MacMillan Cancer Support said this is an extra expense they cannot afford, particularly when they are not working and their income is reduced.

Npower and Macmillan have launched a new fund to cap energy bills and write off debt for eligible Npower customers who are struggling. Npower also supports Macmillan’s Energy Advice Team, which offers help and guidance for people, regardless of their energy supplier.

Other energy groups also offer support. From 1 February, cancer charity CLIC Sargent will work with social care professionals supporting young people and families to identify those who are British Gas customers and are at risk of financial difficulties. The social worker will then refer the family to a specialist British Gas team, which will work with the family to provide tailored packages to ease the financial burden.
