Have you ever tried to save energy, only to discover it doesn't make much difference to your bills? It's one of the fundamental unfairnesses of the standing charge on your utility bills. The more energy you save, the less effect it has on your bills, thanks to the standing charge. It's a charge designed to make sure all accounts make profit, so low energy users don't become 'undesirable' customers. But it means that the owner of a mansion pays the same standing charges as a tenant in a bedsit who uses a fraction of the energy. But there's another problem...

 caused by heating poorly-insulated homes. They have failed to provide proper motivation for households to take energy efficiency seriously.
Energy upgrades can be very expensive, and long-term cost is a key factor in people's decisions ... how much money will it save? The answer is 'Not as much as you'd hoped', because the standing charge reduces the rewards of saving energy. The result is that it takes longer to pay for itself, so those big investment - in insulation, heat pumps, solar panels etc. -  become harder to justify. 
  
If standing charge deters investment, could the situation be reversed to stimulate homes to invest in energy efficiency? Instead of a standing charge, could a standing credit be the answer?
Instead of a daily charge on your bill, you get a daily credit. But it isn't a free handout from the energy company. You get a free energy allowance, but each unit of gas/electricity also costs more, so the average household sees no difference. However, energy savers see big reductions in their bills, whilst those that burn more pay significantly more.

The idea originates from energy pressure group Fuel Poverty Action.
Example of how the standing credit works
A standing credit could ease fuel poverty and stimulate energy efficiency without affecting fuel companies’ bottom line – except by reducing fossil fuel sales. Windfall taxes and other subsidies can then target insulating rented sector homes:

7 reasons to introduce the Standing Credit
(1) Targeted relief for fuel poverty without complicated handouts.
(2) Strong incentive for major energy upgrades without complicated grants.
(3) Shifts the energy cost burden to persistent high energy users. It targets wealthier owners of larger properties, most likely to be able to afford insulation and heat pumps that will bring their bills back down.
(4) Makes energy efficiency more affordable by reducing the payback period. 
(5) Instantly stimulates fast energy reductions that the UK urgently needs.
(6) Building activity stimulates growth instead of inflation.
(7) Fall in demand lowers gas prices.
5 issues that a Standing Credit must address
(1) Vulnerable customers - some of the highest energy consuming households belong to 'vulnerable customers' often on low incomes. These could be elderly people that keep their homes unbearably hot, but can't control it because they have dementia, or individuals dependant on power-hungry medical machinery to keep them alive. Presumably these cases can be identified and their needs met with support channeled through relevant caring agencies.
(2) The standing charge guarantees that all customers generate a profit for energy suppliers. The standing credit would result in some customers paying nothing, which could make them unattractive to energy suppliers, leading to them being cut off. The solutions could include a new formula which continues to remunerate supply companies based on service levels, perhaps by reallocating the 'per unit supplied' income. Alternatively, unprofitable customers could be moved to a different income stream, which is levied from the total pool of 'profitable' customers. Energy companies could decide who they consider profitable or not.
(3) The Standing Credit provides a strong incentive for home owner-occupiers, but less so for landlords, leading to an unacceptable situation where tenants are vulnerable to higher energy bills. Solutions could include (a) a standing credit based on energy rating (subsidised by the landlord?), or (b) other measures to ensure that landlords face the penalties of energy inefficiency, not the tenants, such as the 'Warm rent' system used in Germany.
(4) Should the standing credit be one-size-fits-all, or tailored to the number of occupants or bedrooms? Should a terraced house divided into three flats each with their own energy accounts receive three standing credits when the HMO (house in multiple occupation) with one bill only gets the one standing credit to share amongst its tenants? A simple solution could be for the standing credit to be divided into bands based on property value, like the council tax.
(5) Standing credit needs some flexibility to adapt to whichever fuel customer uses to heat their home (ie gas, electricity, oil etc). Eg., customers won't switch to electric heat pumps if they can't bring their gas credit with them, or else they will lose out.
