Security Deposits, Payment Difficulties, Disconnections and
Suppliers of heat to domestic consumers. Section B applies where heat is supplied to domestic consumers. A network serving only non-domestic consumers is not subject to it.
What this condition requires
Do not require a Domestic Consumer to pay a Security Deposit for supply to domestic premises (9.1); any permitted deposit must not exceed a reasonable amount (9.2). Offer the payment-difficulty services in 9.6 when you become aware or have reason to believe a Domestic Consumer is having or will have difficulty paying (9.3), making proactive contact at the earliest opportunity (9.5). Take all reasonable steps to ascertain the consumer's ability to pay and take it into account when setting instalments, giving due consideration to the matters in 9.8 (9.7-9.8). Domestic Supply Contract terms must reflect 9.3 to 9.7 and B10, stipulate that charges may not be demanded otherwise, and continue to bind you even if you cease to be authorised or the authorisation is revoked (9.9-9.11). Do not Disconnect for non-payment without first taking all reasonable steps (9.12); Disconnection includes Credit Limiting in the circumstances in 9.13. Do not Disconnect in Winter where occupants are within the protected categories, and take all reasonable steps to ascertain whether they are before exercising any right to Disconnect (9.14-9.15). Equivalent restrictions apply to Bulk Suppliers (9.16). Prepare and make available a plain-language statement of your obligations under 9.3 to 9.15 (9.18). Where a consumer pays by fixed regular direct debit, explain the basis of the amount, ensure it is based on the best and most current information available, and refund accumulated Consumer Credit Balances on request (9.19-9.22).
