British Gas business energy tariffs
In this section, we’ll summarise the small business energy tariffs offered by British Gas.
For businesses with higher energy demands, British Gas also provides customised quotes and additional procurement options tailored to meet specific energy needs.
Fixed Price Plan
The British Gas business Fixed Price Plan provides companies with a fixed electricity or gas rate over a contract term of 1 to 3 years, ensuring stability against market price fluctuations. This makes it an ideal option for companies seeking predictable energy costs.
Customers can benefit from a personalised online quote, and those who pay by Direct Debit receive a 7% discount. While the unit rate remains constant throughout the contract, monthly bills will vary based on actual energy consumption.
Payments must be made on time, as failure to do so could lead to higher rates being applied.
Renewable Energy Plan
British Gas Business includes zero-carbon electricity as standard in all new and renewed fixed-term contracts. For businesses looking to enhance their green credentials even further, there are options to upgrade to low-carbon or fully renewable energy plans for an additional premium.
The Renewable Business Energy plan from British Gas is designed for businesses that consume more than 150,000 kWh of gas or electricity annually.
This plan offers 100% renewable electricity and carbon-neutral gas, helping companies reduce their carbon footprint.
Variable Price Plan
The Variable Price Plan from British Gas Business applies to customers who have yet to renew their fixed-term contract before it ends.
This plan, also known as out-of-contract rates, has unit rates per kWh that increase or decrease with the wholesale market.
British Gas will notify customers 30 days in advance if rates change. Importantly, customers can switch to another plan or supplier at any time without penalty.
Half-Hourly Meters
The British Gas business half-hourly price plan offers tailored energy solutions for businesses with higher electricity demands.
Designed for companies that consume large amounts of energy, this service allows for more precise business energy monitoring, as meters are read every 30 minutes.
By utilising half-hourly meter data, businesses can better manage and optimise their energy usage, potentially lowering costs and improving efficiency.
Deemed Tariff
If you’ve recently moved into a new business premises supplied by British Gas and haven’t arranged an energy contract, you’ll automatically be placed on their deemed rates.
These rates tend to be higher than standard business energy tariffs. However, you can easily switch to a more cost-effective plan with no fees by contacting the business moves team at British Gas.
British Gas business energy contract features
Our business energy experts have summarised the important points of the British Gas business Terms and Conditions, which form the business energy contract for small business customers.
Payment Methods
Small business customers who opt for Direct Debit payments receive a 7% discount on their energy rates.
However, British Gas will adjust prices or remove any applicable discounts if the Direct Debit is cancelled or refused. Timely payments are essential to maintain the agreed rates and terms.
End of Contract
British Gas will notify you around 60 days before your fixed energy plan ends. If no action is taken, you’ll automatically be moved to the Variable Price Plan (VPP), which typically has higher rates.
If you wish to switch to a new plan or supplier at the end of your fixed-term contract, you must provide 30 days’ notice.
However, once on the VPP, you can change plans or switch business energy suppliers at any time without providing notice.
Credit Checks
British Gas reserves the right to conduct credit checks at any time to ensure customers meet payment obligations.
Failure to comply with these credit requirements may result in switching to a more expensive variable rate plan. In such cases, they may also cancel your contract, require a different payment method, request a security deposit, or increase your prices.
Switching Suppliers
Customers can switch suppliers at the end of their contract but must provide 30 days’ notice.
However, switching can be blocked if there are unpaid debts or if the customer attempts to switch before their fixed-term or notice period ends.
Contract Changes
If legal or regulatory requirements change, British Gas can adjust the terms and conditions.
British Gas will communicate any such changes in writing by email or through the customer’s online account.
