Energy efficiency is a measure of energy used for delivering a given service. Improving energy efficiency means getting more from the energy that we use. DECC - Energy Efficiency Strategy: 'The Energy Efficiency Opportunity in the UK'
  • When it comes to saving energy and reducing costs, measuring and recording your energy use is absolutely fundamental.

  • As weather conditions and temperatures change throughout the year, it's a given that the amount of energy needed for heating changes too. This makes comparing energy efficiency season-to-season difficult — no one month or year is the same as the next.

    This is where a calculation known as 'degree days' can help.
