As a result of Government legislation it has been possible for the domestic consumer to switch gas supplier since April 1996 and electricity supplier since September 1998.
From what had effectively been a closed market open to only 14 electricity companies and 2 gas companies there are now some 60 suppliers of gas and electricity to the domestic consumer.
It is currently estimated by OFGEM that up to 160,000 consumers change supplier each week.
The usual reasons for switching supplier are to save money, to purchase a
green product or to receive an improved level of customer service. ![]()
Ofgem is the regulator for Britain 's gas and electricity industries. Its
role is to protect and advance the interests of consumers by promoting competition
where possible, and through regulation only where necessary. Applying this
principle has resulted in great benefits for all gas and electricity customers. ![]()
energywatch was set up by the Utilities Act (2000) to be an advocate for consumers
in the gas and electricity markets, it acts as the independent gas and electricity
consumer watchdog. They are here to help you with whatever consumer issue you
have regarding the gas and electricity industry. ![]()

Energylinx offers you the opportunity, free of charge, to find the very best available deal for your home, based on your own personal circumstances, by analysing every supplier in the UK .
All of this occurs by inputting a few basic pieces of information into one of our calculators, Energylinx then presents you with the top 20 suppliers based on your requirements.
To change supplier it is then a simple case of accepting one of the quotes
provided. ![]()
1. First select one of our calculators, electricity only, gas only or dual fuel.
2. Input the basic information requested.
3. Review the results presented against your current supplier and from those listed.
4. You can either save the information by setting up your own secure personal account or proceed to change supplier by selecting the supplier of your choice.
5. You will then enter the secure area where you will be asked to input personal information and your meter identification numbers (either MPAN for electricity or MPR for gas). These can be found on your existing bills - see our FAQs on Meter Identification.
6. After completion of the required fields, you will be presented with a summary
page where you can see the details of your proposed transfer. If you are happy
press confirm. You will immediately receive an email with all the details of
your new energy contract and information as to what happens from here. ![]()
It takes between 28 and 40 days from the date you arranged to change supplier
until you are actually being supplied by them. ![]()
If you use Energylinx to change suppliers there is no need as we take care of all notifications for you.
On occasions an existing supplier may contact you to change your mind, although to date we have never heard of anyone being offered a better deal as domestic tariffs are usually fixed.
In the majority of cases the transfer is entirely seamless. And from a regulatory
viewpoint both OFGEM and Energywatch keep a close check on this. ![]()
Not at all. The pipes, cables and meters you currently have will stay exactly
the same.
Energylinx does not charge you for the use of our services. They are offered on a free of charge basis.
Some suppliers pay Energylinx a referral fee. The payment of this fee does not affect their positioning or inclusion in our calculators.
Please note that, our service to you is free of charge. We do not actually
collect any payments through our web site, nor do we enter into a contract
with you, save as per our terms and conditions.
We appreciate your custom and encourage you to switch to your new supplier
through the links on our web site. ![]()
All the information contained within our databases is current information.
Historic, or non-available, tariffs are not included. ![]()
Whilst some suppliers apply charges for late payments, these are not taken
into account by our calculators and we assume that payments are made on the
due date. ![]()
These calculators assume that you are taking advantage of the British Gas
discounts for prompt payment on standard credit accounts. ![]()
VAT is currently charged at 5% on home energy bills. Our calculators take this
into account and all prices provided include this.
One aspect to consider when changing supplier is customer service. Whilst the level of customer service from the suppliers will not affect the actual supplies of gas or electricity to your home they will affect how the supplier interacts with you as a client.
Energylinx, Energywatch and Ofgem are all keen to promote the requirements
of higher levels of customer service throughout the industry. You will find
further details of current levels on the menu link to Supplier Standards. ![]()
Although some suppliers offer additional non-cash incentives these are not
taken into account by our calculators, they are of course listed for your information. ![]()

GAS SUPPLY - If you do not have a bill or cannot see it the information on a recent bill, call Transco's Meter Helpline on 0870 608 1524 and ask them for your MPRN number and name of your registered supplier if it not shown or your recent gas accounts.
ELECTRICITY SUPPLY - Again the first step is look at a recent electricity
bill, if it not clear what your MPAN (Meter Point Administration Number) call
your local electricity distribution company. You should ask for their Meter
Point Administration Service (MPAS). ![]()
When we talk about meter numbers, we actually mean in the case of electricity your MPAN number and in the case of gas your MPRN number. These are not the numbers printed on your actual gas or electricity meters, rather they are effectively your unique supplier reference numbers.
ELECTRICITY
The first place to look for your MPAN number is your most recent electricity bill, where you will find it printed. If you do not have a bill then the best idea is to contact your electricity distribution company. This is not necessarily your current supplier. If you look at our UK Generation Map you will be able to find out who your local distribution company is by hovering over your location and clicking to check that your postcode is included. If you call them and ask for the Metering Point Administration department, they will tell you what your Supply Number is. You can obtain the local distribution company's telephone number either from the local telephone directory or from directory enquiries.
The number that you will be provided is either the full 21 digit number or the 13 digit part number. Either will be acceptable to allow you to change supplier.
GAS
The first place to look for your MPRN number us your most gas bill, where you will find it printed. If you do not have a bill you can call Transco's Meter Helpline on 0870 608 1524 and ask them for your MPRN number.Site Map | Affiliates | Terms of Use | Privacy Policy | News
