Cavity wall insulation. Most homes built since 1920 have a gap between internal and external walls. Filling the cavity with insulating mineral wool and foam means cold air's kept out, and warm air stays in. It can save an average three-bedroom home up to £150/year. We've heard of certain cases where damp has formed after having cavity wall insulation installed, so make sure it's appropriate for your home.

In Maryland, you have the power to choose your electricity and natural gas suppliers. More than 500,000 Marylanders have already switched energy suppliers. Need a good reason to switch? Some suppliers regularly offer rates and service that are 10% or more cheaper than the utility. Things could get worse - Baltimore Gas and Electric Co. has proposed a rate increase it says would boost the average residential customer's total bill by $5.77 per month. A recent Choose Energy survey found that more than 86 percent say they've never chosen a competitive Maryland electricity plan, meaning they're probably paying more than they have to for energy.

Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
