Over 60% of Isle of Wight homes will need to be upgraded to secure an EPC C rating of C or above by 2035 if the UK is to be on track to meet net zero.

The scale of the energy efficiency opportunity has been highlighted in 2 new reports, undertaken by sustainable energy experts Regen.

The reports, commissioned by Scottish and Southern Electricity Networks (SSEN), forecast that energy efficiency measures will need to be upgraded in 50,000 Isle of Wight homes by over the next 15 years.

Heating is responsible for around 18% of the UK’s annual carbon emissions and for over 31% of average UK household emissions. Research by the Climate Change Committee (CCC) found that for the UK to be on track for net zero all buildings will need to be upgraded to have an Energy Performance Certificate (EPC) rating of ‘C’ over the next 10-15 years. This will require improving the energy efficiency of 19 million buildings.

The reports apply the UK’s national targets at a local level and found that:

  • 1 in 3 homes on the Isle of Wight have an EPC rating of E or below. There is high potential to reduce energy demand and bills through energy efficiency measures.
  • Over 60% of Isle of Wight homes will need to be upgraded to secure an EPC C rating of C or above by 2035.
  • By 2035 energy efficiency measures will need to reduce current demand by up to 29% to put the UK on the path to net zero.

Energy efficiency measures support decarbonisation and lowering household bills. The UK Government has calculated that upgrading all UK homes to EPC C could provide annual energy bill savings of £7.5billion and it is targeting ‘as many homes as possible’, to have an EPC C rating by 2035.

SSEN has published the reports on its website and will be sharing the findings with local authorities, regional stakeholders, and the UK and Scottish Governments to help inform and target investment decisions. SSEN is committed to working with the local communities it serves to help them realise their net zero goals.

Andrew Roper, SSEN’s Distribution System Operation and ED2 Director welcomed the reports:

“Energy efficiency will have a critical role in securing a fair, cost-effective and secure transition to net zero. These reports provide a welcome illustration on what realising the UK and Scottish Governments’ ambitious targets will mean for the homes, businesses and communities we serve.

“It critically important to look at the impact on electricity demand in the round and by taking this industry-leading step to analyse energy efficiency, it will help better inform our investment plans as we prepare for the next price control period, RIIO-ED2. We are committed to sharing data and learnings to support national and local efforts to turn ambition into action and put the UK on the path to net zero.”

And the Government’s contribution is:

1. abandon legislation to force all new homes to meet highest efficiency standards
2. withdraw second attempt at green support plan
3. issue mixed messages about airports (and whatever you do, don’t lie down in front of the bulldozers extending Heathrow!)

I would think the people who live in poorly insulated homes likely aren’t able to afford to insulate them to standards. Certainly an issue which financial help would solve. They scrapped the green homes energy grant a few days ago which would have helped.

I don’t think a strongly worded goal can magic insulation into homes but maybe it will encourage them to visit their nearest well to make a wish for it.
