How will my gas bill be affected by the energy price cap?

Based on Ofgem's typical domestic usage, the energy price cap level is set to £1,717 taking effect from 1 October 2024. This change reflects a typical household that uses gas and electricity and pays by direct debit. 

Ofgem sets the price cap to make sure prices are fair for users on default energy tariffs, and that it reflects the underlying costs and inflation of the energy market. They review and update the price cap every three months.

Is Electricity Cheaper at Night? How Off-Peak Energy Works

9 oct 2024 - When it comes to lowering your energy bills, timing can be everything. So, is electricity cheaper at night?

https://images.ctfassets.net/0sn9t583vfn4/3463FIcTNqGcVRD0irZYs6/02da64449a1dc92257e16b2e9cfb47c7/bills-paper-man-image.png

What is a kWh and how much is it?

Understanding gas and electricity costs:
Ever looked at your energy bill and wondered, 'What is a kWh?'. Don't worry, you're not alone.

How long will it take to switch my gas supplier to UW?

It can take two to five working days to get you switched over from your existing provider. During that time, we’ll do all the work so you won’t have to worry about anything. 

We’ll keep you updated throughout the process, but you can also track the progress via our free mobile app.

Do I need to contact my current gas supplier?

No, we’ll contact your current gas provider to let them know about your move. 

In a few weeks, we’ll ask you for meter readings; at this point, we’ll start billing you for your gas, and your current supplier will stop (so you won't pay for the same energy twice). 

If your balance is in credit, your old supplier will then arrange to send you a final invoice and refund your money back to you. If your balance is in debt, we recommend you clear this with your current supplier before switching to UW.

How do I read my gas meter?

All traditional or non-smart meters are different, but the basic rules for reading them are typically the same: always read the numbers from left to right and ignore any numbers in red or after a decimal point.

If you have a smart meter, models tend to vary slightly more. You can find out how to read your smart meter for your manufacturer’s meter here.

How can I find out who my gas supplier is?

If you’ve just moved into a property and aren’t sure who your gas supplier is, enter your postcode into the Energy Network Association search tool to find your network operator.

Then, you can contact your network operator for your supplier details. They’ll also be able to provide you with your electricity Meter Point Administration Number (MPAN), which tells your energy supplier where your meter is and your gas supply number.

How is my gas bill calculated?

Your gas meter measures the amount of gas you’ve used in cubic metres or cubic feet. We take your reading and convert this to kWh when we calculate your bill.

The calculation to convert kWh is different depending on whether you have a metric or imperial gas meter:

  • For metric meters – We multiply the cubic metre (m3) figure by the Correction Factor (1.02264) and then by the Calorific Value (CV). Finally, we divide the result by 3.6 to reach your kWh figure.

  • For imperial meters – The calculation is the same, except we have to first convert a cubic feet (ft3) measurement into cubic metres. We do this by multiplying it by 2.83.

We then multiply each kWh you use by your unit rate.

Find out more about how your gas bill is calculated here.

What does Calorific Value on my gas bill mean?

Calorific Value (CV) relates to how much heat is generated when a certain amount of gas is completely burned away.

Essentially, CV measures the quality of gas supplied to a property. Each bill we send you will show the CV that's been calculated for your area for that month, and it will range between 37.5 and 43.0.

Can UW supply my home with electricity and gas?

Yes! We can supply both gas and electricity to your home with a dual fuel plan, where you get both utilities on the same contract. 

Discover our cheapest gas and electricity deals when you bundle two or more services with UW. Find out more about our energy and electricity tariffs here, or visit our pricing page to learn how you can save on your bills by combining our services.

Do you provide boiler cover?

Yes, we offer Boiler & Home Cover exclusively to all our UW homeowners who have an established direct debit set up.

Our Defaqto and Moneyfacts 5-star insurance includes a free annual boiler service, support from our 24/7 claims team, and unlimited call-outs so you can be sure you’ll be in safe hands if disaster strikes.
