The benefits of new, energy efficient boilers are multiple:
They reduce the cost of keeping a home warm, something particularly important to customers on low incomes. Installation of a condensing boiler provides an estimated fuel bill saving of up to £225 per year per household.
They can improve physical health, with benefits for both the customer and society. Cold housing can affect specific conditions, such as cardio-vascular or respiratory diseases (CVD). The average cost of a hospital admission requiring a surgical procedure due to CVD is £4,614 and around a third of all excess winter deaths are caused by CVD.
In total Age UK estimates that deaths arising from cold homes cost the NHS £1.3 billion per year and the Building Research Establishment estimate that the average cost to the NHS of excess cold in a home is circa £20,000.
Damp, cold homes can affect mental health and increase the likelihood of depression and anxiety. In more general terms if someone is unable to keep themselves warm it is simply impossible to imagine them feeling in good health overall; good overall health carries a HACT wellbeing value of £20,141 indicating the significance of its impact.
Taking just the potential energy cost savings, new boilers can pay for themselves within eight years. If new boilers prevent serious cold and damp related NHS admissions in even 1% of installations, the NHS savings would outweigh the cost of the programme in under 10 years. If 10% of customers were to experience improved physical health as a result, then wellbeing values would exceed new boiler costs in year one alone.
