Ruby Energy tariffs

In this section, we summarise the business energy tariffs offered by Ruby Energy.

fixed

Fixed Rate Tariffs

Ruby Energy’s fixed rate electricity and gas tariffs are designed for businesses that want price certainty. Unit rates are agreed at the start of the contract and remain fixed for the full term, helping to protect against wholesale market fluctuations. Bills are based on actual business energy usage.

Variable tariff

Market Tracker Tariffs

The Market Tracker tariff links electricity or gas prices to movements in the wholesale energy market. Prices are reviewed regularly and can rise or fall in line with market conditions. This option may suit businesses that are comfortable with some price volatility and want the opportunity to benefit when market rates fall.

SmartPay

Budget Payment Plan (BPP)

Ruby Energy’s Budget Payment Plan is available for gas customers who want more predictable monthly payments. Estimated annual gas usage is used to spread costs evenly across the year, helping businesses manage cash flow. Payments are reviewed periodically and adjusted if usage changes significantly, ensuring bills remain as accurate as possible.

Ruby Energy contract features

Our business energy experts have reviewed the terms and conditions for Ruby Energy to highlight the key contract features businesses should be aware of before entering into an agreement.

Payment methods

Payment methods

Ruby Energy requires all payments to be made by Direct Debit, unless otherwise agreed in writing. Bills are issued monthly through the online portal as part of its paperless billing system, and customers are responsible for checking and paying invoices on time.

If a Direct Debit is cancelled or fails, Ruby Energy may apply higher rates. Late payments can also result in late fees, interest charges, referral fees for site visits, or supply restrictions.

End of contract

End of contract

Fixed-term contracts run for the agreed duration stated in the contract details. Customers can give written notice to end their contract at any time during the fixed term to prevent automatic extensions.

Ruby Energy sends a renewal reminder no later than 60 days before the end of the contract, outlining renewal prices and termination deadlines. If no notice is received, the contract may continue on short extension periods or move onto out-of-contract rates.

Credit Check

Credit checks

Ruby Energy may carry out credit checks as part of customer onboarding and during the life of the contract.

If credit requirements are not met, the supplier may request up-front payments or alternative payment arrangements. Additional security may also be required if a business’s financial position deteriorates.

switch

Switching suppliers

Businesses can switch business energy suppliers at the end of their fixed term or during extension periods. Ruby Energy may object to a transfer where there are unpaid charges or where switching would breach contract terms.

If an account is in arrears, Ruby Energy may block a transfer until outstanding balances are settled. Customers on deemed contracts are generally able to switch at any time.

Meter access

Meter access and meter readings

Customers must allow reasonable access to energy meters for readings, inspections, testing, and maintenance. Where actual readings are unavailable, Ruby Energy may issue estimated bills.

The supplier aims to install smart meters or automatic meter reading devices where possible. If access is refused or installation is prevented, customers may be charged higher non-smart rates to cover required additional visits.

Ruby Energy customer reviews
