Home Energy Saving
With 40% of the UK’s carbon emissions attributed to the transport and residential sectors, there is a long way to go before we achieve the 2020 reduction target of 34% below 1990 levels.
Many people still believe that their actions do not make a difference to but the statistics are showing that we decreased our UK net CO2 emissions by 8.7% in 2008 and 9.8% in 2009. There are now so many ways to save money, energy and the planet without having to invest too much time or effort. This section will focus on the small, medium and large solutions which can significantly help to reduce the carbon emissions your home produces and fight climate change.
The average house spends on average: £1230 on fuel bills each year which can be up to 50% more than necessary due to the lack of energy saving measures being implemented in the home.
There is also an Energy Saving Checklist which you can download to help you decide which measures you might want to adopt straightaway and those which may need a little more time, planning and financial investment.
All houses when bought, sold or rented require an Energy Performance Certificate (EPC) this is an assessment about how energy efficient the property is. They cost around £150 and the rating given is similar to that of household appliances ranging from A-G, A being the most efficient.
Minimising Heat Loss
Draught proofing is a low cost but highly effective solution to reducing heat loss throughout your home. Typically all the entrance and exits will have some degree of heat loss as well as window frames, chimneys, letterboxes and cat flaps. Also any gaps between floor boards, skirting boards or service can be areas where draughts can occur; these can easily be eradicated with sealant paste.
Removing the draughts not only keeps heat in during the winter but the heat out during the summer. You can simply determine where heat is escaping with a small feather or burning joss stick – if the smoke or feather moves you know you have a draught to deal with.
It is however important to be mindful that some fuel burning appliances do require some ventilation and also timbers in the roof and floor.
Windows will be the next problem if you don’t or can’t have double glazing and while it may not be the cheapest solution, installing secondary glazing or even triple glazing, will ensure you are draught free.
If you can’t afford to replace your doors and windows some of the easiest and cheapest measures for draught proofing are as follows:
- Draught Proof Door Compression Seals
- Draught Proof Letter Box
- Draught Proof Door Wiper Seals
- Thermal Curtain Linings
- Sausage Dog Draught Excluders
Insulation is one of the most cost effective ways of retaining heat within a home and is part of the Governments focus towards homeowners to reduce fuel bills. Millions of homes in the UK still do not have adequate insulation. Go outside when the snow comes and look at your property. If the snow is settling on your neighbours’ roofs and not on yours, heat is escaping through your roof and you are paying the energy bill to melt that snow!
Loft insulation is one of the easiest ways to help retain heat and is heavily subsidised by energy suppliers and even free for qualifying residents (low income and those over 70). The more loft insulation you install, the less heat that is lost. The optimum thickness has been shown to be 350mm, Building Regulations insist on a minimum of 270mm.
If your loft space has been converted into a room then you will need to insulate in the sloping roof. High levels of insulation can be hard to achieve because a free air space of 50mm must be left between the insulation and the tiling felt, unless the felt is low-vapour resistant. The most economic way of achieving a good thickness of insulation in the roof slope is to have two layers of timber: the first to support the roof finish, the second to support the insulation and ceiling finish. Insulation can then fill in between the timbers, providing a thermal break between the timbers.
If you wish to be as "green" as possible fit loft insulation from a natural and sustainable resource such as Thermafleece made from sheep’s wool.
In order to maximise heat retention older properties can benefit from cavity wall insulation which again is subsidised by energy suppliers but can also be installed relatively cheaply. The wall insulation stops heat leaving or entering the cavity wall space therefore helping to reduce the need to switch heating systems on more frequently in winter or air conditioning unit’s on during the summer.
Also available is floor insulation however this can be a much more invasive installation as floors have to be removed in order to put the insulation into the space between joists.
- Loft Insulation
- Cavity Wall Insulation
- Floor / Ceiling Insulation
Any door or window in your property has the potential to release heat out of your home. If your doors have gaps you can see through, it might be a cheaper long-term solution to replace them, ensuring they are professionally fitted and contain triple glazing.
The same applies to your windows and although the cost of both doors and windows does require significant investment, the amount saved in heating bills could pay back the outlay much faster than you think.
- Double Glazing (or secondary glazing)
- Triple Glazing
- Thermal Glass / Solar Glass
- Draught Proof replacement Doors
Although rather expensive, double glazed windows are superb insulators compared to single glazed windows. If climate change is going to mean colder winters then the payback time will come down from decades to years when double glazing your home.
However not all windows can be double glazed. English Heritage estimates that there are 44 million single glazed sash windows in the UK many of which are in listed buildings. For these and as an alternative to double glazing, there are replacement glass and glass coating products such as thermal glass on the market that are efficient at stopping heat loss and also trap solar heat inside the building. This is the greenhouse effect working for your benefit.
Sunpipes are an innovative way to pipe natural daylight from your rooftop into your home to save on electricity bills by brightening areas from dusk till dawn where daylight from windows cannot reach.
Reducing Fuel Bills
Put all clothes washing at a 30 degree wash cycle
Only boil enough water for the amount you need
Use microwaves and induction hobs as they are the most energy efficient methods of cooking
Use energy efficient light bulbs
Switch off as many appliances and entertainment systems as possible when not in use
Take a 5 minute Shower instead of a bath
Collect Rainwater for use in the garden
Install a toilet Savaflush device
Change all taps to water saving models
Change Shower head or system to incorporate water saving
Turn your heating thermostat down by 1 or more degrees tosave 10% on your heating bills
Turn your hot water temperature down; the standard heat setting is usually 60 degrees
Buy A+ rated Appliances: When buying a new appliance it is useful to look at the energy rating especially for frequently used high energy items such as washing machines, fridges and freezers.
Appliances are rated from A to G. All white goods such as washing machines, tumble dryers, dishwashers, fidges and freezers.
A is the most energy efficient. As the technology and energy efficiency of products has increases so have the ratings.
Fridges and Freezers also now have A+ and A++ ratings.
Buy A or B rated Combi/Condensing Boiler: All new boilers installed must now be either A or B energy efficiency rated.
If you can’t upgrade your boiler then lagging your hot water tank makes sense and is relatively inexpensive. Why pay to heat the water and then let the heat dissipate away? Fit a British Standard jacket that's at least 7.5cm thick.
It will cost around £10 and will give a saving of £10-£15 a year. Hot water pipes can also be insulated to stop heat escaping from them. The best pipes to insulate are the ones between the boiler and hot water cylinder. Cost: around £1 per metre.
In order to have a much larger impact on your carbon emissions the best solution is to install renewable energy or microgeneration technology in your home. You can find more detail on each technology throughout the website.
Although these solutions do involve higher investment the payback and reduction in both energy bills and carbon emissions is significant. Solutions include:
- Solar water heating can reduce your gas bills by generating up to 60% of your hot water needs. Flat plate solar panels or evacuated tubes are installed on the roof and connected to your boiler system.
- Electricity can be generated by installing photovoltaic panels. With the new Feed in Tariff (FIT) this is a good way to supply energy to your home, reduce your bills, receive income for the energy you use and any additional electricity sent back to the grid.
- Wind Power is often a highly topical issue across the UK where wind farm are concerned but it is possible to generate electricity by installing a small scale wind turbine. It is essential that a full site survey is completed initially to see whether the investment and location will provide a suitable return both in power and financial gain.
- Electricity has been generated by the power of water for many years now but more often only in large scale environments. However it is possible to generate electricity for your home through hydroelectric power if you have proper access to or own a river or stream as part of your property.
- Ground and air source heating is a method of generating heat from under the ground using the power of a heat pump. This solution is ideal for new build or refurbishments where underfloor heating may be installed. Retrofitting can be complicated and disruptive to existing gardens and flooring.
Underfloor heating without ground or air source, is still a very energy efficient way to heat your home. You can either purchase a wet or electric system. The wet method is a low temperature heating system that, used in conjunction with a condensing boiler, can be 20% more fuel efficient than the equivalent radiator based system.
Underfloor heating provides radiant heat which raises the temperature of the fabric of the room which suppresses the perception of body heat loss while also being warm underfoot. This in turn maintains a constant heat which lasts longer meaning the overall temperature of the system can be much lower than the heat and energy needed for traditional wet/radiator systems.
Recycling and Re-using
Most people have now become accustomed to recycling and are used to dividing up their household items to ensure that the minimum amount of waste goes to land fill. There are over 2300 landfill sites across the UK and it is not simply a question of waste but the methane gas which it creates is a contributor to climate change. Leachate is also a bi-product of older landfill sites and can pollute our water supplies.
Although many councils are collecting a lot of items now there is still so much more we can do to help our carbon emissions, reduce waste and help fight against climate change no matter how small the action.
Items which can be recycled
By the council:
Glass, Paper, Card, Plastic, Green Garden Waste
By your local Recycling Centre (also charity shops, rag and bone man etc):
Foil, Batteries, Bicycles, Books, Christmas Trees, Computers, Mobile Phones, Old Drugs, Egg, Boxes, Furniture, Aluminium, Steel, Tin, Oil, Paint, Printer/Toner Cartridges, Shoes, Clothes, Eye Glasses, TV’s, Tyres
Sometimes it is important to think about the wider ramifications about how, what and where we buy our food and household items.
Below are just a few suggestions which will help reduce carbon emissions beyond the UK and your own waste levels.
- Reduce packaging: buy loose fruit and vegetables and non processed foods, look for the minimum of packaging you can find.
- Buy UK or local food: Look for food which has not been imported by air; check the labels to see if it is locally produced or from within the UK.
- Buy Organic: This ensures produce has not been genetically modified or has not been subject to pesticides etc...
- Buy Fairtrade: This ensures that products which are from countries where exploitation has occurred are sourced from fairly paid farmers.
- Buy Organic Soya: The production of Soya is now one of the biggest contributors to the destruction of the Amazon rain forest. If possible buy organic soya from certified sources.
- Buy Local Meat, Fruit and Vegetables: There are many Farmers Markets across the UK now and from an environmental and social perspective buying local supports not only local business in your area but also reduces the carbon footprint of your food.
- Grow your Own: For an almost zero carbon method of food provision, grow your own vegetable patch and reduce your trips to the supermarket and the carbon footprint that goes with it.
- Plastic Bags: In 2009 there was a drive for supermarkets to reduce the amount of plastic bags they gave out and offer re-useable bags to their customers. If you have plastic bags either re-use them or take them back to the supermarket for recycling.
- Aerosols: Although the pollutants in Aerosols have reduced, they still have an impact on greenhouse gas emissions as they contain Hydrofluorocarbons and Carbon Dioxide.
- Cosmetics: Try to buy products which do not have excessive packaging, are not animal tested and have natural or non-toxic properties.
- Cleaning Products: There are now many organic cleaning products on the market which you can buy but many common household cleaning tasks can be completed with white vinegar, bicarbonate of soda, lemon juice and olive oil.
Monitoring Household Fuel Consumption
The Government has set out to ensure all households in the UK become more aware of the gas and electricity they are using. As part of the CERT scheme and the new Green Deal it is intended that every house should have a Smart Meter and energy suppliers have been tasked with distributing these to their customers.
The Smart Meter is attached to the mains cable by the meter and a wireless monitor can be carried around the home to see the usage and cost of electricity.
As items are turned on and off it is possible then to calculate which products use the most electricity. Some meters can be attached to each product and assessed individually.
Although customers will have to pay for the smart meters through an increase to their electricity rates, the hope is that the savings, which are made through becoming more conscious about the energy we use, will far outweigh the increase in cost.
The new Green Deal created by government aims to continue Smart Meter distribution to 2018.
Environmental Building Design
All buildings should aim to cause the minimum harm to the environment whilst maximising the sustainability and adaptability of the building for its potential users throughout its lifecycle.
In its simplest form it means ensuring that a new building makes best use of its orientation and position for solar gain, that it is designed to minimise energy use, that it is insulated as effectively as possible, that it is constructed from materials from sustainable sources and that the wastes that are generated from its use are dealt with ecologically.
The Government’s formal policy is The Code for Sustainable Homes on how to build an energy efficient and sustainable home. It was based on the Building Research Establishment’s Environmental Assessment Method (BREEAM) and the BRE Ecohomes System.
The Code contains six award levels ranging from 10% efficiency to zero carbon. Building Regulation changes in October 2010 now meet Level 3 of the Code which ensures any new building commercial or domestic must be 25% energy efficient.
It is essential for anyone looking to build a property is familiar with the Code for Sustainable Homes and the consequences of the latest changes to Building Regulations. However in order to ensure you meet minimum standards aim further in your design, construction and completion. The more environmentally designed your building the more you will save money and help climate change.
What help is there?
Depending on what you want to do and your circumstances can affect the level of financial help you can receive. Funding is available from Government schemes, Local Authorities and Energy Suppliers.
The current Government funding focuses on insulation and replacement heating systems and boilers more details can be found on our Grants page. The following schemes are currently in place:
England: Warm Front
Wales: Home Energy Efficiency Scheme
Scotland: Energy Assistance Package
Northern Ireland: Warm Homes
Currently there are no government grants available to help with the up-front costs and installation of renewable energy systems but the Government is looking at special green loans and financing deals which have low interest rates to help encourage the adoption of green technology.
The Feed in Tariff and Renewable Heat Incentive are currently the main channels of central government funding for private individuals and homeowners installing renewable energy technology.
The Government also launched a pilot scheme in 2009/10 called Pay as You Save (PAYS), for a selection of 500 homes to have an energy make-over. There were no upfront costs for installation and long term repayments were set which were lower than the predicted energy bill savings. Instead of the loan being allocated to the owner it was placed on the property, so if the house is sold, the loan remains on the house and becomes the responsibility of the new occupier. The pilot scheme has now closed but hopefully a national scheme will be announced as a result.
