So by facing their fears this bank holiday, to tackle some of the jobs they dread most, collectively they could have the same impact as taking 410,000 cars off the road (1.2m tCO2).
On an individual scale there is cash to be saved: doing four simple-to-do home improvements will shave £140 off their annual fuel bill, add value in long-term to their existing home and leave cash for those harder-to-do projects best left to a professional.
The EST carried out a UK-wide survey of more than 2000 consumers and found the top four home improvement jobs most dreaded by the DIY-shy were:
1 Top-up existing loft insulation – 63% would never attempt this job but if they did it would save them £60 a year on energy bills.
2 Put jacket on hot-water cylinder – 44% avoided this despite a £40 annual saving.
3 Draught proof doors & windows – 43% weren’t keen, yet there’s £30 to be had.
4 Insulate or "lag" hot water pipes – 56% didn’t want to know, £10 could be saved here.
Philip Sellwood, Chief Executive of the Energy Saving Trust, said: "Everyone’s purse strings are tighter nowadays, and bank holidays are the perfect time to take-stock and check which DIY jobs will save you cash on the household bills.
"But our research shows many Brits are shying away from easy cash savings by ignoring simple, energy saving tasks which need to be done around the home. This is a real shame. This bank holiday weekend we urge householders to do a free Home Energy Check at the Energy Saving Trust’s website: www.energysavingtrust.org.uk/check to find out which simple things – from draught-proofing to bleeding the radiators – they could do.
"I am sure they will be surprised about the savings they’re missing out on."
Energy and Climate Change Minister Joan Ruddock said: "It really is easy for householders to save energy, save money and help tackle climate change.
"If households across the UK took a few simple steps, not only would they make significant savings on their energy bills, but the whole country would benefit through reduced carbon emissions."
