Free Traffic Legal Advice

Hi all,
After advice on whether to take this to London Tribunals or just pay.
PCN for failure to pay Road User Charge, Blackwall Tunnel, 05/04/2026. £90 discounted, £180 full.
I have an existing TfL account for the tunnel charging. On the day I crossed I tried logging in at reg.web.tflcc.co.uk to check my vehicle was registered properly, whether Autopay was set up, and whether it was still linked to a previously owned vehicle. Got "The login attempt has failed. Please try again." Tried password reset, failed. Created a new account, same error. Tried again the next day, same. Tried from phone, work laptop, and iPad, same on all devices. Still can't log in today.
I'm aware you don't need an account to pay, you can pay without one. But every time I tried to access the payment system, the site kept looping me back to the login page because my credentials were stored. The login was broken, and the site wouldn't let me get past it to reach any payment option. I was going round in circles.
Submitted a representation explaining all this with a screenshot of the error. TfL sent a "Request for Further Evidence" asking why I haven't registered for Autopay. They confirmed they found my "accounts" (plural). I submitted further evidence explaining I can't register because I can't log in, and asked them to check their server logs. Called their helpline as directed, got bounced between numbers, nobody resolved the login issue.
Got a Notice of Rejection from D. Milton. 3 pages!!! copy-paste job explaining how Autopay works. Didn't address the login failure. Didn't confirm whether they checked their logs.
The only evidence I have on my end is screenshots of the login page returning the same error: "The login attempt has failed. Please try again."
Ground at tribunal would be "In the circumstances of the case, no penalty charge is payable." Has anyone seen adjudicators rule on system-failure cases like this? Worth it or should I just pay?

Thanks for your resposne.

It does work, but it has the Sign In on top first thing. I also didn't want to pay if it was setup for payment automatically, but then I couldn't verify anything because I couldn't sign in. I think I had it setup for a previous vehicle I owned... but again, I couldn't confirm anything.

You are correct, I can go and pay that route. What I was trying to say though, I didn't want to go down that route without checking if automated payment was in place or not.

Conscious this would probably be the argument for TfL with the adjudicator, hence why I'm wondering if I stand a chance and risk paying £180

It's wouldn't be a 'slam-dunk' win for you. As you say, TfL will say "why didn't you just make a direct payment"

Don't just let it slide; make a complaint to TfL. They cannot ignore it, and then after that, you might be able to tie them up with a Local Ombudsman complaint.
