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.
Since 1996, when the energy market was opened up to competition, UK consumers have been able to switch energy suppliers to find a cheaper gas and electricity deal. Previously, Ofgem did set a maximum price for energy; but now Ofgem only regulates the market as a whole — that means creating a regulating schemes to support vulnerable households and more.
It is not a well-known fact that consumers can take advantage of energy deregulation and choose an alternative energy supplier, known as an Energy Service Company (ESCO). In addition to offering lower electricity and gas rates, an ESCO can provide other energy options, not otherwise available by your local traditional utility company, such as renewable green energy (solar, wind or hydropower) and fixed-rate plans. Energy deregulation allows residents and businesses to shop around for energy, compare electricity and gas rates, find the cheapest providers and easily switch electricity and gas suppliers online. Compare ESCOs and their rates, choose the cheapest electricity or gas provider, and you can reduce your energy expense, such as Con Edison electric or gas bill, if you live in New York City, or United Illuminating or Eversource bill if you live in Connecticut or Public Service Electric and Gas, Jersey Central Power and Light, Atlantic City Electric, Rockland Electric Company bill if you live in New Jersey. PowerSetter specializes in educating New York, New Jersey and Connecticut residents about comparing electricity and gas providers, and making switching energy suppliers an easy and painless process. In addition to offering tools to compare energy rates, PowerSetter only selects plans with no hidden monthly and/or enrollment fees and works with the most reliable and trusted alternative electric and gas companies.

You can sort, filter, and shop by pricing at YOUR specific usage level, which lets you shop and compare electricity plans based on the rates you’ll actually experience on your bill, inclusive of hidden fees and taxes. This ensures you’re not misled by the cheaper rates often advertised by electric providers…those “teaser rates” associated with higher usage levels that many households never enjoy because their usage level never reaches that pricing tier.
 1.     Contracts:  Before, there were no contracts.  You signed up or you didn’t.  When it’s the only game in town, you have to play by their rules.  Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
You should also check your tenancy agreement – but even if your contract bans switching, Ofgem's guidance on this states that if you pay the energy bill, you're still entitled to change supplier any time. You can still compare on Cheap Energy Club if you don't have the former occupants' bills, just hit the "don't know" button when you enter your usage.
If you think you have to pay the rates your current electricity provider charges, we have good news. The state of Texas allows you to choose which electricity provider you use. This means you can select a provider that has the cheapest Texas electric rates in your area and the best plan for your needs, whether you need a better deal for your residence, your business, or both. Thousands of consumers and businesses that have used our electricity rate comparison process agree that, when shopping for commercial electricity or residential electricity rates and plans, Vault Electricity is the one-stop source for the best options from top electric providers.
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
