British Gas offers two primary business tariffs under two companies.  

Business Gas Lite – Organizations spending less than £10,000 per year on electricity want Business Gas Lite. Here, you will receive a custom quote for energy based on contract type, contract duration, location, and total expenditure. For example, we requested a quote in Liverpool and another in Reading, based on a £6,000 electric expenditure per year and received the following quotes.  

Fixed Rate Term   Standing Charge (Daily)  R p/kWh  City   Contract Type  
1 Year  50.00p  18.10p  Liverpool  Direct 
1 Year   89.91p  24.75p  Liverpool  Partner 
1 Year  50.00p   16.37p  Reading  Direct 
1 Year   89.91  24.75  Reading  Partner 
5 Years   72.00  19.15p  Liverpool  Direct 
5 Years  98.98p  24.03p  Liverpool  Partner 
5 Years   72.00  17.45  Reading  Direct 
5 Years   98.98  24.03  Reading  Partner 

Business Gas Business – Organizations spending more than £10,000 on electric per year get additional perks, discounts, and offerings. British Gas Business comes through with volume discounts to help you meet large electric demands. These quotes are offered on a case-by-case basis and are fully customized to your business. In this case, we received rates anywhere from 5% to 30% lower than the Lite rates.  

Additionally, any business using more than 70kWh of energy (Gas or electric) per year can normally opt into half-hourly metering. This is mandatory for businesses using 100 kWh +. Half-hourly metering will change your tariff rate as British gas will bill for how and when you use electric. E.g., you get a cheaper rate for using electric during non-peak hours.

British Gas Business Reviews & Ratings  

Reviews across Trustpilot and are largely critical, with British Gas scoring an average of 3 stars out of 5 on average. However, 44% of all reviews on Trustpilot are 5 stars. British Gas has many customers meaning they will have a large number of unhappy customers.

Switching to British Gas  

Switching to British Gas is relatively simple. The provider makes it as easy as possible to do so. In fact, if you move into a new business location, British Gas will provide you energy at deemed rates until you set up a contract.  

  1. Contact British Gas with your address and payment method. We’d recommend Direct Debit, for the up to 7% discount on tariffs.  
  2. Discuss terms and choose a plan with the consultant  
  3. Wait for the mandatory 14-day cool-off period to end  
  4. Confirm the switch-over date 
  5. Submit a final meter reading to your old provider 
  6. Send a first meter reading to British Gas 

In most cases, the full process takes 21+ days, including the cool-off period. You can skip the final two steps if you have a Smart Meter or Half-Hourly Metering. If you’re locked into a contract with another provider, it’s unlikely that you want to switch. Check your current contract or provisions before doing so.  

Commercial Energy Billing Process 

British Gas makes it as easy as possible to complete billing. Businesses receive a monthly invoice, complete with itemization, VAT, and deductions. You can opt out of a paper invoice. British Gas also offers an online portal for invoice and payment management.  

If you do not use the payment portal or direct debit, you must submit remittance advice at the time of payment.  

Chance of Tenancy  

If you’re moving into or out of a commercial building supplied by British Gas, it’s easy to switch or start a new contract.  

Moving to a New Location – Login or register for an account with British Gas. You’ll need your account number if you don’t have an account. Submit a moving form. Share your move out date, final meter reading, and forwarding address. You’ll also be asked to supply the name, phone number, and email of the new occupant. If you have a smart meter, it may not be necessary to supply the meter reading.  

Moving into a British Gas Location – Call British Gas at 00 44 113 298 0900 after moving in. Supply your moving date, business details, and first meter reading. You have to negotiate a contract rate at this time.  

Business Bill Payment Methods

  • Payment portal – Log into the British Gas Business Portal and pay your invoice with bank or credit/debit 
  • Bank transfer – Transfer payments manually to British Gas

Submitting Meter Readings  

British Gas uses an online portal for all business energy transactions. Additionally, many British Gas customers are already using smart meters. This can reduce or eliminate the need to submit meter readings.  

You can do so with or without logging into the portal: 

  • Either log into the portal OR check a recent bill for your email address, account number, and postcode.  
  • Submit your meter reading by sharing all the numbers from your meter reading, ignoring any numbers shown in red or after a decimal point.  

Smart Meters

British Gas offers SMETS2 smart meters. Smart meters allow you to use hourly metering, to get monthly cost updates, and to benefit from more accurate bills.  

  • Request a Smart Meter 
  • British Gas will assess eligibility and whether a smart meter is compatible with your premises 
  • If yes, British Gas will install the smart meter for free 

If you use over 100 kWh per year, you’re required to have a smart meter for hourly metering.
