Switching from electric heating to gas, LPG or oil

Electricity is the most expensive and inefficient heating fuel available, and so switching from electric to gas, LPG or oil, whilst expensive, can save you significant amounts of money in the long term.

How to make the switch to gas


1) Connect to the gas network – To be able to use a gas boiler you will need a new gas connection if you don’t have one. Your property must be no more than 23 metres from the nearest main supply line, and your new meter won’t be able to be higher than 3 metres above the ground. You will also need the permission of anyone who owns land between your property and the line, and whoever owns the house if you don’t, as excavation work will be required. You will need to contact your Gas network to install the connection from their main line on your road to your house. Gas networks vary depending on where you live:


National Grid:

East Midlands (East of England)

East Anglia (East of England)

North West

London (North only)

West Midlands

Scotia Gas Networks:


South England (including South London)

Northern Gas Networks:

Northern England

Wales & West Utilities:

Wales and West England


For Scotland, South England (including South London), Northern England, Wales and West England you can instead get the connection done through Utility Infrastructure Providers. You can contact any network including UIPs here.

Getting a connection to the gas network costs between £200 and £500 depending on how much private land is between the main connection and your house and whether you want the gas network to do the excavation required. Costs for National Grid areas can be found here.


You can get help paying for a new connection if:

– You spend more than 10% of your net income on heating

– Your house is in a deprived area

– You are on certain income related benefits

– You are over 70 years old

More information on the National Grid scheme is available here.


2) Get your gas meter installed: One your gas connection is set up you should get your gas supplier to come and install your gas meter. Once that is done, your system is live and can be connected to a central heating system.



How much energy and money could I save with a condensing boiler?
Complete our Home Energy Assessment to find out how much you could save with a condensing boiler.
How easy is it to install a condensing boiler?
Boilers vary in size and shape but most are designed for simplicity of installation. With space being such a premium many boilers are small enough to be fitted by one person into a kitchen cupboard, easily and with minimum disruption.
How can a condensing boiler save me money on my energy bills?
Condensing boilers are more efficient than standard boilers and therefore utilise less gas during operation. Modern conventional boilers can only offer a typical efficiency rate of 78%, whereas the rate for condensing boilers is around 88% - i.e. for every £1 spent spent on gas, 88p is converted to actual heat. This adds up to significant savings on annual gas bills, which will enable you to quickly recoup the initial outlay for the boiler and benefit from the extra savings. Complete our Home Energy Survey to find out just how long payback will take in your situation.
How is the Sedbuk rating calculated?
The 'seasonal efficiency of a domestic boiler in the UK' (Sedbuk) rating for boilers is calculated from the results of standard laboratory tests, together with other important factors such as boiler type and the kind of fuel used. It describes the boiler's efficiency.
How reliable are condensing boilers?
Condensing boilers are reliable if well maintained and serviced regularly. A Which? survey in 2011 found that 46% of owners who bought a boiler after April 2005 have experienced some kind of fault. Not all of these faults required a repair. In fact the most frequent problem, a blocked drainage pipe, experienced by 11% of owners, is actually a problem caused by poor installation.
