THIWASCO payment not working? Top fixes
Common failure modes when paying THIWASCO via M-PESA, with the first fix to try. If none of these resolve it, the 10-character M-PESA transaction code is the universal proof of payment, keep the SMS until the issue clears.
Money left M-PESA but the meter still shows zero credit, or the postpaid bill still reads as unpaid in the account portal.
For prepaid meters, wait five minutes then key in the 20-digit token from the M-PESA SMS into the meter manually. For postpaid, give the bill up to 24 hours to reflect. If neither resolves it, phone the operator with your 10-character M-PESA transaction code: that is the only thing they need to trace your payment.

Paying THIWASCO from outside Kenya
If you are abroad and this is a bill for family at home, the usual route costs you twice. You pay a transfer fee to get money into someone's M-PESA, then paying 860100 from that wallet is charged again on the M-PESA paybill tariff.
Before you send, check whether your transfer provider can pay a Kenyan paybill directly rather than paying a person. If it can, the money goes straight to THIWASCO, the second charge never happens, and nobody at home has to do anything. Providers differ on this and it changes, so confirm it in your own app rather than taking anyone else's word.
The exact M-PESA charge depends on the amount. Work it out on this page, or compare what the transfer itself costs on the send-money comparison.
