Save Money on Energy Bills

We are committed to helping residents to put in place some of the energy savings measures. To find out more or to schedule a free Home Energy Evaluation please contact the Energy Team via our Customer Services Centre on 01206 282514 and we will visit your home as soon as possible.

There are various ways you can reduce your energy consumption and your impact on the environment, both by changing your behaviour and looking at your energy supplier


Lighting accounts for 8 per cent of a typical household’s energy bill. Cutting your lighting bill is one of the easiest ways to save energy and money. Changing how we use our lights by implementing control mechanisms and being conscious of our behavioural habits can save money and energy. Here are a few easy things to help you start saving:

  • Always turn lights out when leaving a room regardless of how short a period it is for.
  • Be conscious of how many lights you have on and whether they all need to be in use.
  • Use a sensor and timer on external lights so they are only in use when they need to be.
  • Use appropriate lighting e.g. a low background light while watching television and a bright, concentrated light for reading. Having a range of lights in a room with separate switches will make this easier.

Houses typically use a mixture of standard light fittings and down-lighters or spotlight fittings. Energy efficient bulbs are available for both types of fittings. Changing which bulbs you use and how you use them will instantly save your home energy and money.

There are two main types of energy efficient light bulbs available in the UK: Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).

CFLs are what you typically think of as an energy efficient light bulb. CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a compact fluorescent light bulb (CFL) of the same brightness will save you around £3 per year, or £50 over the lifetime of the bulb.

LEDs are available to fit both types of fittings and are particularly good for replacing spotlights and dimmable lights. Though more expensive to buy initially, they are more efficient than CFLs and will save you more money in the long term. Replacing a halogen spotlight with an equivalent LED will save you around £4 each year, or £140 over the bulb’s lifetime.

Buying green energy

Most of of the UK’s electricity comes from burning fossil fuels (such as coal, oil and gas) which is a major contributor to climate change. There are various options available to make your energy supply more sustainable.

Carbon-free electricity  

Carbon-free sources of electricity, including nuclear and renewable, account for around a quarter of total electricity production. Renewable or ‘green’ electricity accounted for just 6.7% in 2009, but the proportion is growing steadily. This increase is due to policies such as the Renewable’s Obligation (find details of the Renewable’s Obligation at the OFGEM website) and the Feed-In Tariff, which support new renewable generation, as well as reductions in total electricity demand, which make the existing renewable contribution go further. The Government wants at least 30% of our electricity to come from renewable sources by 2020.

Green electricity offerings 

Most energy suppliers offer ‘green’ electricity tariffs. These seek to support renewable energy. The two main types of offering are green supply tariffs and green funds.

Green supply tariffs

A green supply tariff means that some or all of the electricity you buy is ‘matched’ by purchases of renewable energy that your energy supplier makes on your behalf. These could come from a variety of renewable energy sources such as wind farms and hydroelectric power stations. Your supplier should let you know what sources are included in the mixture, and also what proportion of your supply is renewable.

Many green tariffs state that your supply is renewable but they simply assign some of the renewable energy they are already required to supply to you, while reducing the amount of renewable energy they provide to other customers. This does not increase the amount of renewable’s in the overall energy mix.

Some companies will guarantee that a proportion of the renewable energy they are purchasing (and you are buying) is ‘additional’ – it is above and beyond what suppliers are already required to produce. This creates an additional incentive to develop new generation capacity and so could lead to increased renewable generation and reduced carbon dioxide emissions.

There are no companies offering green tariffs that are 100% additional renewable supply.

Green funds

A green fund usually involves paying a premium to contribute to a fund that will be used to support new renewable energy developments. Under this option, the existing electricity supply continues as normal, but your involvement could help to alter the mixture of energy sources in future toward renewable sources (depending on the type of tariff).

The new generation projects supported may also receive support under existing government support schemes.

Green Energy Supply Certification Scheme 

In February 2010, the Green Energy Supply Certification Scheme was launched. This scheme was set up to reduce customer confusion and mis-selling in this marketplace. These tariffs have been independently checked, and meet the energy regulator OFGEM’s Green Energy Supply Guidelines. Find out more on the Green Energy Scheme website.

But although these tariffs demonstrate real carbon savings, they do not ensure that the electricity you buy is 100% renewable or that it creates additional renewable energy generation.

In order to comply with the scheme, suppliers must ‘match all the energy you use with Renewable Energy Guarantees of Origin (REGOs). REGOs are certificates attached to electricity produced from renewable sources. These can be bought from any EU member state.

But the claim of ‘matching’ the energy you buy with renewable energy does not necessarily mean that you are increasing the amount of renewable energy produced in the UK or abroad. The supplier only has to show that they have purchased enough renewable energy to supply it to all their customers who have signed up to their Green Tariff. Suppliers are already obliged to supply a certain amount of renewable energy regardless of whether you sign up to a green tariff.

The supplier must also do at least one of these:

  • Carbon offsetting so long as it is certified under either DECC’s Quality Assurance Scheme for Carbon Offsetting (QAS) or the Gold Standard for regulated credits. This could include for example the provision of fuel efficient stoves abroad. If offsetting is done through the QAS, 1.8 tonnes of CO2 must be offset. If offsetting is done through the Gold Standard 1 tonne of CO2 must be offset.
  • Additional activities which could include energy efficiency measures such as cavity wall and loft insulation, and advice (as long as these savings are measurable and not being claimed for under other schemes which place obligations on electricity suppliers). At least 50kg of CO2 per customer per year must be saved through this method.
  • Green Fund that could be used to invest in measures such as renewable’s on community buildings. At least 50kg of CO2 per customer per year must be saved through this method.
  • Other activities accepted by the assessment panel – this is a voluntary scheme and not all suppliers or tariffs are required to use it. However, all suppliers who have joined the scheme can no longer market other non-certified tariffs as ‘Green’.
How green are green tariffs? 
  • Opting for a green tariff will not mean that the electricity you buy is all renewable. You cannot consider that your electricity supply is zero carbon or carbon neutral.
  • Opting for a green tariff can provide additional incentives for new renewable generation or energy efficiency measures, and so lead to some additional carbon dioxide savings in the long term.
  • If you opt for a Certified Green Energy Supply, then there will be some guaranteed additional benefit. However, this could be as little as 50 kg carbon dioxide saved per year, or around 2% of the average household’s carbon dioxide emissions from electricity use.
  • Green tariffs are no substitute for energy efficiency – you should always do whatever you reasonably can to reduce your current use of electricity and other fuels before considering spending money on a green tariff.
  • The Energy Saving Trust does not recommend specific suppliers of green tariffs.
