Loft insulation

Installing these measures will reduce your heating bills and we calculate that this could be as much as £340 a year for a 1940’s 3 bed semi detached home with a ten year old gas boiler and a gas price of 3.407p/kWh. More modern homes save less. Your individual savings depend on a large number of factors and the £340 quoted should be treated as a guide. Also experience tells us that many customers like to have a warmer home, making it more comfortable. This reduces the saving. But even allowing for this, both forms of insulation are a worth-while investment.

Double glazing
The figures are based on CO2 saving from the Energy Savings Trust (EST) figures as of 04/09/07 and assuming gas price of 3.407p/kWh.

Rotary clothes dryer
Energy saving is based on a 25% reduction in the average annual tumble dryer usage by letting clothes dry naturally, and uses an electricity rate of 10.086p/kWh.

< Back to top

Solar Panels
The energy and CO2 savings are based on Energy Saving Trust (EST) figures as at 29/07/09, using a gas unit rate of 3.407p/kWh.

< Back to top

Energy saving light bulbs
Savings are based on four hours use per day of a low energy equivalent to a 40W light bulb, and an electricity cost of 10.086p/kWh (including VAT).

< Back to top

Television and Home Entertainment
Energy savings based on switching off home entertainment equipment (set top boxes, DVDs, games, TV etc) rather than leaving them on standby when the attached television is not in use . This assumes the television is used 4.1 hours per day at an electricity unit rate of 10.086p/kWh. 

< Back to top

Thermostat
The 10% per 1°C energy saving is based on the Energy Saving Trust (EST) cost saving figures as of 29/07/09 and using a gas unit rate of 3.407pkWh .

< Back to top

Radiator reflectors
Energy saving figures are based on Ofgem CERT savings for approved silvered panels located on external solid wall (or uninsulated cavity) and assume 6m² of panel. Using a gas unit rate of 3.407p/kWh.  

< Back to top

Eco Kettle
The energy saving is based on a typical use equivalent to 10 cups per day (0.3 litres per cup) and an electricity unit rate of 10.086p/kWh.

< Back to top

PowerDown
The energy saving is based on a range of separately powered computer peripherals such as monitor, printer, scanner, modem etc that are switched off when the computer is not in use. The figures assume the computer is used for 3.11 hours per day and an electricity unit rate of 10.086p/kWh per unit.

< Back to top

Electrisave
The energy savings are based on Department of Energy and Climate Change CO2 figures for real time display that can save up to 3.5% of electricity used in the home and an electricity unit rate of 10.086p/kWh.  

< Back to top

Towel radiator
Energy saving based on a 30 day per year reduction in use of a 100W electric towel rail, and uses an electricity unit rate of 10.086p/kWh.

< Back to top

Shower
Energy saving is based on using a daily 5 minute shower using 35 litres of water, instead of a daily bath using 80 litres of water. This assumes a boiler operating at 90% efficiency and gas unit rate of 3.407p/kWh.

< Back to top

Bath
Energy saving is based on a 140 litre, foam insulated, electric immersion heater that is switched off when going on a 2 week holiday, and an electricity unit rate of 10.086 p/kWh.

< Back to top

Hot Water Tank Jacket
Based on Energy Saving Trust (EST) CO2 savings when fitting a new 75mm thick British Standard tank jacket and a gas unit cost of 3.407p/kWh.

< Back to top

‘A’ rated tumble dryer
Energy saving based on 148 uses per year of an 'A' rated tumble dryer with heat pump, compared to the average existing tumble dryer. Electricity unit cost used is 10.086p/kWh.

< Back to top

Boiler
Based on the Energy Saving Trust (EST) CO2 savings for replacing an old 'G' rated inefficient boiler with a new 'A' rated efficient condensing gas boiler (including new controls) for a 3 bedroom semi-detached house and using a gas unit rate of 3.407p/kWh.

< Back to top

Clothes horse
Energy saving is based on a 25% reduction in the average annual tumble dryer usage by letting clothes dry naturally, and uses an electricity rate of 10.086p/kWh.

< Back to top

Cat-flap/draft insulation
Energy saving is based on the Energy Saving Trust (EST) annual draught proofing CO2 saving amount for a 3 bedroom semi-detached house, and a gas unit rate of 3.407p/kWh.

< Back to top

Luminaire - Table Lamp and Pink Fluffi
Saving is based on 4 hours use per day of a 10W energy saving luminaire instead of a 40W standard bulb, and uses an electricity unit cost of 10.086p/kWh.

< Back to top

TRV
Figures based on the Ofgem CERT saving for gas central heated home (assuming 7 radiators, all controlled by thermostatic radiator valves), and a gas unit rate of 3.407p/kWh.
