Silvertown or Blackwall Tunnel — wrong charge or wrong time
Using the Silvertown or Blackwall Tunnel is only chargeable during certain hours, and the charge varies depending on the time of day and which direction you travelled — peak or off-peak. There is no charge at all overnight. If your penalty notice was issued for a crossing made outside the chargeable hours, or if you were charged the higher peak rate when your crossing was actually off-peak, the ticket may be wrong.
Legal basis
The Transport for London (Silvertown Tunnel and Blackwall Tunnel) road user charging scheme (charging hours and peak/off-peak rates by direction); Road User Charging Schemes (Penalty Charges, Adjudication and Enforcement) (England) Regulations 2013 (SI 2013/1783), reg. 4 — ground that the contravention did not occur (no charge due) or the penalty exceeds the amount applicable.
How to identify this in your case
Look at the exact time and direction of travel shown on your penalty notice. Then check TfL's published charging hours and peak windows. Ask yourself: was your crossing made outside the chargeable hours altogether? Or does your crossing time fall in an off-peak window, but you were charged the higher peak rate? If either of those is true, you may have grounds to challenge.
