Many of the world's biggest challenges, from poverty to wildlife extinction, are made more difficult by climate change. And things will get worse if we do nothing. But we can do something about it.

Our homes are leaking energy and money, and contributing to climate change, because they lack a basic standard of energy efficiency. The energy waste from inefficient homes is costing the UK £8 billion per year. For people, for species and for the planet, the UK government must act now to end this waste!

Take a minute to send a message to your MP to show you want UK Government action for better homes, that tackle climate change.

The last three years have been the hottest on record, with the impacts of a warming climate being felt across the globe and here at home in the UK. Reducing energy waste in homes is a low-cost way to reduce carbon emissions, but too few homes are improved each year. Emissions from housing are rising, which is why we urgently need the UK Government to do more to help people insulate their homes to improve energy efficiency.

I am writing to you to ask the UK Government to take three steps to tackle this problem in its forthcoming plan to reduce carbon emissions:

  • Set a target to bring all homes in England and Wales to an Energy Performance Certificate (EPC) ‘C’ rating by 2035: installing high-quality energy efficiency in homes could reduce their emissions by 30%, making them cheaper to heat and healthier, which could save the NHS £1.36 billion every year.
  • Amend the minimum energy standards for rented homes: the new standards are welcome, but as currently written will allow most landlords to avoid making simple improvements that would keep their tenants warmer, healthier and save them money.
  • Ensure that all new homes are ultra-low emissions from 2020: current building standards allow new homes to be built that aren’t as energy efficient or low carbon as they could be, and will need retrofitting to hit our 2050 climate change target.

I would be very grateful if you could write on my behalf to the Secretary of State for Business, Energy and Industrial Strategy, Greg Clark and the Secretary of State for Communities and Local Government, Sajid Javid to recommend the three important changes I highlight above.

The exact  amount of energy and money that can be saved through installing insulation measures will differ from household to household. Our calculations are based on models taken from the Energy Saving Trust . These have been produced by models based on the typical types of homes commonly found across England, Scotland and Wales, with the assumption that they are heated to 21 ° C in the home’s living area and 18 ° C in other areas of the home. The model assumes that houses are heated with gas, and with an average boiler efficiency of 82%.
