12% through ventilation and draughts, e.g. through the chimney Up to 26% heat loss through the roof
Did you know?
28%
Homes are responsible for over a quarter of UK energy usage and CO2 emissions†.
26%
We all use energy to live our lives and your home is the one place where you’re likely to have the most control over your usage.
Where does it all go? Energy loss in a typical uninsulated home Up to 33% heat loss through uninsulated walls
Since 2007 average UK household gas and electricity bills have grown by just under £400 a year - which is a 30% increase in real terms *. That’s why saving energy is becoming increasingly important. Also, just think how many energy-hungry, laboursaving and comfort-creating devices we now have in our homes compared to years ago.
33%
As a low carbon energy provider, we at Co-operative Energy are doing our bit. How? By ensuring that the carbon content of our electricity is less than half the national average. Reducing CO 2 is great for the planet, but these days, you’re probably more interested in saving money.
Did you know?
£334
That’s how much most customers underestimated the average UK energy bill by in 2012††.
Fortunately, there are serious savings to be made by not only reducing the amount of energy you use, but also doing things a little smarter and taking advantage of energy saving products. Our guide is designed to help you to quickly and easily increase the energy efficiency of your home, reduce your impact on the planet and ultimately save on your energy bills.

Energy is precious: Saving energy at a glance
Saving energy at a glance Here are some simple things you can do at home to save both money and energy If everyone knew just how much energy everything in their homes consumed, they might do things a little differently. The thing is, energy touches so many parts of our lives, we sometimes don’t appreciate just how much it all adds up. Here are just a few astonishing facts about everyday energy usage: n
T urning down your central heating thermostat by 1°C will save you £65 a year
n
A dishwasher will use less water than washing up by hand if used in the most energy efficient way
n
A void leaving devices on standby and you could save £50-£90 a year
n
ake sure your washing machine is full before M putting it on, and always use the most water and energy efficient settings
n A
third of heat in a non-insulated home is lost through the walls and a quarter through the roof
n
S etting your washing machine to wash at 30°C instead of higher temperatures will save £13, that you could spend on socks!
n
R eplacing an average desktop computer and monitor with a new Energy Saving Trust Recommended laptop could save £26 per year
n
Y our walls, floors and ceilings can contibute to 50% of the heat loss in your home. Insulating these will help reduce this
n
R eplacing a traditional light bulb with an energy-saving bulb saves £50 on average in electricity over its lifetime
In the spirit of always being honest with our customers, we’d like to point out that all savings mentioned in this document are approximate figures and should only be used as broad guide.
Energy saving monitors can save you up to 15% Energy saving monitors are the easy and simple way to show you how much energy your electrical appliances are consuming. A smart meter or energy saving monitor with in-home display can help you cut electricity use by at least 5%, by increasing your awareness of household electricity use. You can order an energy saving monitor for £25.00 (inc VAT) and could recoup the cost within the first few months of use.

Smart tips
When you’re buying new, it pays to buy energy efficient Technology is always finding new ways to not only use energy, but use it more efficiently too. So if you’re replacing your windows or electrical appliances, make energy efficiency a major consideration. By doing so, you could save energy and money every year for the life of the products – it’s like getting a long-term discount on whatever you buy. Buy energy efficient appliances Update your appliances with new ones that carry the Energy Saving Trust or Energy Recommendation logos. A, A+ and A++ are the most energy efficient choices, whilst G rated are the most inefficient. It pays too as replacing even a D-rated fridge/freezer that costs around £94 a year to run with an A++ rated model costing just £25 to run would save you £69 each and every year.
Look to buy appliances that have high efficiency ratings the higher the rating, the more you’ll save!
