There are lots of price comparison sites out there that will allow you to compare gas prices before you switch has supplier. However, each may provide a different list of suppliers to choose from. In order to ensure that you get accurate quotes from suppliers that will be a good fit for your household, it’s a good idea to have the following information to hand :

  • Your address and postcode
  • Your current gas provider’s name
  • Your current tariff name
  • Your annual or monthly energy consumption

These will ensure that you don’t get any unpleasant surprises after you switch gas provider. If you’re unable to ascertain your energy consumption, you will be asked to choose whether your gas consumption is low, medium or high.

These are defined as follows :

  • Low- 8,000 kWh of gas per year
  • Medium- 12,000 kWh of gas per year
  • High- 17,000 kWh of gas per year

How to switch gas suppliers for cheaper energy ?

Once you’ve found a gas tariff that looks good to you, all you have to do is complete the signup process. Your new supplier will take care of the rest. They will contact your old supplier to arrange the handover of your gas supply, and establish a date for your switch. This is usually within 15 days, and if your switch takes longer you are entitled to £30 in compensation. Make sure you take a meter reading on the day of your switch to ensure that your final bill from your old energy supplier is accurate. You will receive your final bill up to 6 weeks after your switch has taken place. If there is any crest remaining on your account, this will be refunded to you within 10 days.

Average gas prices per kWh

When comparing gas providers and tariffs you’ll see that costs are partially measured in unit rates per kilowatt hour (kWh). These can vary a great deal by supplier. However, it may help to know the average gas price per kWh so you can get a good idea of which providers represent the best value for money when you switch gas provider.

At the time of writing, the average gas unit price in the UK is 3.8 pence. Nonetheless, you’re likely to find a number of gas providers charging below this rate. There are even a number of green energy suppliers that can provide carbon-neutral or carbon-offset gas at below-average prices..

What does 1 kWh represent ?

A kilowatt hour (kWh) is the energy industry standard measurement for a unit of gas. But what does this unit mean? Your gas meter actually tracks your gas consumption in cubic meters (m3) rather than kWh. Gas providers then convert this into kWh for simplicity of billing.

kWh to m3 conversion

Many energy consumers like to track their gas usage. And unless you have a smart meter, you’ll need to perform some calculations to find out what your usage in cubic meters means in monetary terms.

To see how much you’re spending on the gas you use, you can apply this simple conversion.

  • Deduct your last meter reading from the current meter reading to ascertain your usage in cubic meters.
  • Multiply the amount of gas in cubic meters by 11.1868 to convert it into kWh.
  • Multiply this by your supplier’s unit rate per kWh to calculate your spend.

How do gas providers set prices?

Several factors go into determining how much gas providers charge you for what you use. The primary component is the wholesale cost of energy (how much the gas costs the providers) to the state of national and global gas production. There’s also the administrative costs associated with running and marketing the company. Not to mention good old supply and demand.

Because demand for wholesale gas fluctuates throughout the year, gas providers buy their gas in advance to protect themselves from rising costs and provide the best possible value for money for their customers.

What makes up your gas bill?

Your gas bill is composed of two elements :

  1. Unit costs per kWh
  2. Daily standing charges

Standing charges can range from anywhere between 10p and 80p per day. There are some gas tariffs on the market that have no standing charges. However, you should think twice before signing up to one of these. A tariff with no standing charge is usually offset by very high unit costs. As such, they are only really suitable or households with low gas usage, or homes that are unoccupied for much of the year. You should keep this in mind when you switch gas providers.

Can you switch natural gas providers?

Yes, absolutely! It’s quick and easy to switch gas providers, and the process is usually completed within a fortnight. After which you can enjoy cheaper (and potentially greener) gas from a new supplier.

Although we want to make it as easy as possible to switch gas providers, the more you know about your gas supply and the energy industry the better positioned you are to choose the right deal for your needs.

Who is my current gas supplier?

Knowing your current gas supplier and tariff can help you to properly gauge your potential savings when you switch to a new gas provider. If you’re not sure what your current tariff is, you can check your most recent bill. If it’s still unclear, you can always contact your gas provider to check. But what if you have no idea who supplies your gas?

The fastest way to check who supplies gas to your property is to contact your area’s gas transporter.
