How energy efficiency benefits residents and businesses in London



This report by the Association for the Conservation of Energy (ACE) highlights the potential for improved energy performance across London’s buildings. According to the report, 830,000 of the city’s 3,350,000 homes are very energy inefficient, failing to deliver health and comfort to their inhabitants. Furthermore, only 34% of the capital’s non-domestic buildings deliver high energy productivity for the firms using them; the energy waste from the remainder limits the competitiveness of London’s businesses.


The report says that, as London’s most heavily used infrastructure, the city’s homes and workplaces are capable of producing broad and deep benefits when their energy efficiency is improved:


  • Well maintained homes and businesses: The homes that Londoners live in and the buildings where they work are a significant driver of the amount of energy used by the city. A better insulated building needs less energy to keep it at a comfortable temperature. Efficient and well maintained heating, ventilation, hot water and lighting services also help to keep running costs down, whether at home or at work.
  • Keeping money in the local economy: London’s homes and workplaces spend upwards of £7.9 billion on energy bills every year – money which doesn’t stay in London’s economy. Improving efficiency and cutting energy costs means more invested in and spent on London’s economy, while further improving its energy productivity and competitiveness
  • Creating skilled jobs: As many of these efficiency improvements are delivered by London businesses, an ambitious national retrofit programme for homes, with London taking up its fair share, would support 10,300 jobs in the capital.
  • Improving health and wellbeing: Thermal comfort in the work environment is now well-established as a real boon to workers’ health, wellbeing and productivity, and cold homes have been shown to be damaging to both physical and mental health. For every £1 invested in renovating cold homes the NHS saves 42 pence in reduced hospital admissions and GP visits.


The report concludes that a step-change in energy efficiency delivery is needed, combined with a panoramic view and thorough understanding of all the benefits it can bring. Capturing the above benefits simultaneously, by investing in the energy performance of the capital's buildings will help London to meet its targets, maintain its economic competitiveness and be a place that people want –and can afford– to live and work.
