A good way to begin is by visiting our online energy efficiency area which offers comprehensive advice on saving energy and products to help you do this.

We also have an Energy Savers report which you can complete online to find out how energy efficient your home is.

In addition, we offer an energy survey of your home carried out by trained energy experts for just £40. Our Home Energy Assessment includes:

• a personalised energy saving report
• advice on the best energy-saving measures

Find out more about our Home Energy Assessments.

Our tips can help you save energy throughout your home - and cut your bills. Get tips on everything from cooking to using your electrical appliances. Read more about our energy saving tips.

The Energy Saving Trust offers free impartial advice on how to stop wasting energy and has a range of great tips. Why not get advice directly from the 
Energy Saving Trust.

There are a range of products that can help you save energy in your home - and cut your bills. They include:

• energy saving light bulbs
• standby power savers
• insulation for water tanks and pipes
• radiator panels
• thermostatic radiator valves
• eco-friendly appliances, including TV's and kettles

To take a look at the energy saving products available from British Gas go to our Energy Savers Store.

Given their components, we don't recommend putting energy saving light bulbs and fluorescent tubes in your normal household waste. Instead, we'd suggest you have them recycled - they can be disposed of at your local authority Household Waste Recycling Centre in the separate containers that they have available for these lamps.

Energy Saving Light bulbs work in much the same way as a fluorescent tube. They contain electronic components and a very small amount of mercury - just enough to cover the tip of a ballpoint pen. This mercury is an essential ingredient and allows the bulb to deliver their substantial energy saving benefits.

You can sign up if you are one of the following:

• an eligible energy customer who produces their own electricity from a renewable source i.e. if you generate your own electricity through a solar PV system.
• an energy customer of a supplier who does not have to pay Feed-in Tariff cashback. If you're unsure, ask your supplier.

You don't usually need planning permission for most home solar technology systems, but check first with your local planning officer, especially if your building is listed, or is in a conservation area or World Heritage Site. If you're unsure, give us a call on 0800 077 3770.*

*Calls may be recorded and/or monitored for quality assurance and compliance purposes.

Yes. Please call us on for full warranty details on 0800 077 3770* or

Is a solar technology system covered by Building Regulations?

Yes, we'll inform Building Control for you.

*Calls may be recorded and/or monitored for quality assurance and compliance purposes.

A solar PV system does not normally need servicing as it has no moving parts and the other components, such as cables and connectors, are designed to withstand environmental conditions. We suggest you routinely visually inspect your system though (from ground level only) and if you notice any damage, we're here to advise you.

A solar thermal system should be serviced annually along with your general boiler service.

Do the solar panels need regular cleaning?

Usually the rain will do all the cleaning needed. If not, just get in touch, selecting the 'solar PV' option.

You can book an appointment for a free survey of your home either online or over the phone. When you book online, we ask you to give us two preferred days and times and then our Home Insulation Team will call you to advise the exact date.

Whichever way you choose to book your survey appointment, we will always send you a confirmation letter in the post.

If you'd like to arrange a survey you can either book it online or call us on 0800 077 3880*. The survey times available are Monday to Friday 
8am-12pm or 12pm-5pm.

*Calls may be recorded and/or monitored for quality assurance and compliance purposes.

How will I know if my property is suitable for cavity wall insulation?

If your property was built between 1932 and 1982 then you are likely to have cavity walls. If the thickness of your wall is greater than 11 inches then the likelihood of the property having a cavity is high.

Is cavity wall insulation work guaranteed?

How is cavity wall insulation installed?

The insulation is blown in through the holes made in the wall, which are no bigger than 18mm to 25mm. The holes are then filled in afterwards and matched to the existing appearance of your wall. It's all done from the outside, so it will not affect the appearance of the inside of your home.

The survey will normally take between 1-2 hours to complete.

Will I need to be at home while the home insulation survey is carried out?
