Answer 1

What major changes can I make in my home to save energy?

• The ideas in this section are great ways to conserve energy, but they’re expensive, so you’ll need to weigh up whether you can afford the initial outlay, and whether they’ll save you money as well as energy in the long run.

Insulation

• Insulate your loft or roof space. A quarter of heat is lost through the roof, so insulation will make your home warmer and reduce your heating bills.
• Insulate under the floorboards on the ground floor – it will save you about £45 - £55 a year. You can also seal the gaps between floors and skirting boards; it’s easy to do it yourself with a tube of sealant from a DIY store. Floorboards need ventilation, however, or they’ll rot, so don't block any under-floor air-bricks in your outside walls.
• Replace heat-leaking doors and windows with double-glazed (or even triple-glazed) airtight UPVC versions.
• Lag your hot water tank. A properly-fitting tank jacket could save you around £25 to £35 a year – or even more if you heat your water by electricity.
• Insulate hot water pipes to save energy and help your taps to run hot faster.
• Insulate cavity walls.
• If you have solid walls, they can be insulated too – either from the inside or the outside. It costs more than insulating standard cavity walls, but the savings on your heating bills will be bigger too.
• If you can’t insulate your walls, books make good insulation – and soundproofing! Place bookcases against the walls or build shelves and pack them with reading matter. Wardrobes also work well.

Renewables

• Install solar thermal panels. They take energy from the sun and use it to heat water, which can cut your heating bills and reduce your carbon emissions.
• Invest in photovoltaic (PV) solar panels. These create electricity that can power appliances and light your home – and you can earn money by selling any surplus back to the national grid. Find out more by reading our guide to solar panels.

Appliances and devices

• Replace inefficient, energy-guzzling old appliances, even if they still seem to be doing their job. They could be costing you much more than you think.
• Whenever you’re buying a new appliance, choose the most energy-efficient model you can afford. It will cost more, but the operating costs should be lower in the long term. If you choose well, the savings could pay back the extra cost in just a few years. Look out for EU energy labels and choose an appliance that’s rated A+ or better if you can.
• Shop during the sales; you may be able to get a more energy-efficient appliance for your budget.
• Do your research. Carry out an internet search before you visit any showrooms or websites, to make sure you know all about energy ratings and which models have the best scores.
• You should also compare warranties, service contracts, delivery charges and installation costs. Once again, if a particular company is offering a free extended warranty and free delivery, it may mean you can afford a more energy-efficient model.
• If you’re buying a new washing machine, try to plumb it in close to the boiler, to stop heat getting lost as it travels from the boiler to the washing machine (although you should also use a cold cycle whenever possible).

Heating systems

• If you’re installing a new heating or hot water system, carefully compare the costs of all your options. If your home can get mains gas, that’s usually cheaper than electricity or oil.
• Combination boilers provide instant heat when it’s needed, so they tend to be more cost-effective than a tank that needs to be heated up and might run out of hot water if everyone in the family is trying to have a shower in the morning..

Outside your home

• If you’re installing an external security lighting system, use halogen light bulbs, as they consume around 25% less electricity than their incandescent cousins.
• Use timers, heat sensors or motion detectors to make sure these external lights only come on when needed.
• Buying a new lawn mower? Look at electric models. They’re quieter, less polluting, and more energy efficient than petrol-powered mowers. Of course, an old-fashioned manual push-and-pull lawn mower is the most energy saving of all.
• If you have a hot tub or swimming pool, keep it covered when you’re not using it. You can buy solar covers that use the sun’s warmth to heat the water.
• And finally, for the sake of energy conservation for future generations, whenever you’re replacing old, inefficient appliances, please recycle them reponsible
