The Notices of Enforcement are dated 20/07/2024. These notices have to give you seven clear days to pay up. Yours have to be paid by 23:59 on 09/08/2024. Which is unusually generous from Marston. So let's make sure all is in proper order.
Please phone the Traffic Enforcement Centre (TEC) at Northampton County Court, Tel: 0300-123 1059, Monday am if possible.
For each PCN please find out the date the warrant was issued by the TEC, and whether the warrant was re-issued with a new address and when? Please report back. The TEC is open at 09:00 to 17:00. But phone earlier rather than later. The PCN numbers are the reference numbers beginning BS on the Notices of Enforcement.
It won't cost you any more money to submit Out of Time applications. So you might as well have a go. However it's hard to know what you can put on the OOT that helps explain why you are late. A six year out of date address for the RK is very hard to explain.
If Bristol object then your applications will be rejected. And it is likely financially unviable to try, or even if you might be able, to get that rejection reversed. So it's vital to maximise you chances of success with the OOT applications, which is why I referred you to
Bailiff Advice Online. I still believe it would be best to get advice from them.
