I, Jon Johnson, promise to increase the insulation in my walls and loft

Potential savings could be 3,604,440 Hendersons' bottles full of CO2 and £340 per year

Advice to help you fulfil your promise

As much as 33% of all the heat produced in your home is lost through un-insulated walls. Up to 25% could be escaping through un-insulated lofts. On average you could be wasting £340 a year on your fuel costs. Not only that, but you could be pumping out an unnecessary 1839kg of carbon every year. That’s the equivalent of driving around 6000 miles in an average car

Figures from the Energy Saving Trust show that installing cavity wall insulation could save you £150 on your energy bills and cut carbon by 800 kg. If you were also to fit loft insulation (270mm) you'd save a further £190 and an extra 1,039 kg of CO2!

What if my wall is solid?

Solid wall insulation is more complicated and costly than cavity wall insulation. A professional installer should do the work.

It involves insulating and then weatherproofing the external walls.  A layer of render or cladding, onto which a decorative finish is applied, provides weatherproofing.  It is particularly cost effective when your outside walls need repairing or re-rendering.

Alternatively, you could insulate the inside of your walls. You can do this yourself if you're an experienced "DIYer" and reduce the cost even further, especially if you do it when your walls need repairing or redecorating.  It is, however, still a major piece of work, and you will have to take off and refit all skirting boards, doors and window surrounds.

Lagging Lofts

Like cavity wall insulation, loft insulation has the benefit of being cooling in summer and warming in winter. It’s one of the easiest and most cost effective energy saving things you can do. Your home may already have some loft insulation, but if the material is thin, it won't be saving you as much as it could.  Fitting proper loft insulation is the easiest and most cost-effective way of saving energy. The thicker the material, the greater the saving.  If you have older, thinner loft insulation, think about replacing it with new material at least 270mm (11") thick. This can save around 20% of your heating costs.

You can get loft insulation from any DIY store or builders' merchant. Make sure that you wear the correct safety clothing, or ask an installer to do the work for you.
