Understanding your gas or electricity bill - Centre for Sustainable …
Gas meters measure in units of 100s of cubic feet (hcf) or cubic meters (m3), but gas is sold in kilowatt hours (kWh). The conversion calculation is displayed on your bill. The example bill above shows a calculation for a metric meter. You can convert from hcf to m3 by multiplying by 2.83. This is the charge you pay per day, regardless of how ...
Economy 7 - Centre for Sustainable Energy
Economy 7 is an electricity tariff in which the cost of the electricity you use is different, depending on the time of day. The hours of cheap electricity are normally from 12 midnight until 07.00 in winter, and from 01.00 to 08.00 in summer, though this can vary between suppliers. Sometimes people talk about ‘day-rate’ and ‘night-rate ...
Heat pumps - Centre for Sustainable Energy
are most suitable for small flats. They cost around £4,000 to £6,000 to install, depending on size, which is much cheaper than an air-to-water heat pump. Note that air-to-air heat pumps are not included in the Boiler Upgrade Scheme. Hybrid heat pumps combine two technologies, a heat pump and a boiler.
Battery storage - Centre for Sustainable Energy
Domestic battery storage is a rapidly evolving technology which allows households to store electricity for later use. Domestic batteries are typically used alongside solar photovoltaic (PV) panels. But it can also be used to store cheap, off-peak electricity from the grid, which can then be used during peak hours (16.00 to 20.00).

Energy saving myths - Centre for Sustainable Energy
Set the thermostat to a sensible room temperature, between 18-21C, and then leave it alone. If I turn all the radiators down low, I’ll save money. But only if you also turn your thermostat down at the same time. If you turn your radiators down low but still have the thermostat set to 21C, your boiler will keep running until the room ...
DIY loft insulation - Centre for Sustainable Energy
2024年2月29日 · Insulating your loft is a simple and effective way to reduce heat loss, keeping you warmer in the winter and cutting energy bills. Fitting the insulation yourself can help keep the cost down. The table below shows typical figures based on a loft of a typical 3-bedroom semi, and using mineral fibre. Other materials may cost more.
