Hello,

I have received a NIP for an alleged speeding fine from surrey police for a camera at location S79, A23 Horley Road, South Earlswood, at 01.35 hours on 24th Oct 2025.
The original NIP was received within time.
There were some letters backwards and forwards with the police but eventually i received a Conditional Offer of fixed penalty (3 points and £100 fine).
However looking at the Certificate of calibration, I believe that it could be argued that the certificate is out of date.
Allow me to explain.

It effectively has three relevant dates:
Radar Factory Calibration Date  16/11/2023
Initial Site Calibration Start Date  20/12/2023
Annual Inspection Date  25/11/2024
And a stated “Valid Until*” date of: 24/11/2025
and then some wording
* Site Calibration Valid until up to one year from Site Calibration/ Calibration Inspection Date, or three years from Radar Factory Calibration Date, whichever is sooner.

The key words here I believe are "whichever is sooner"
Therefore of the 3 possible options, the soonest date is Site Calibration Valid until up to one year from Site Calibration 16/11/2023 therefore the certificate woud be valid until 15/11/2024 and NOT 24/11/25.

Am I correct in my understanding and reading?
are these grounds to challenge?
or should i accept the offer?

Also, would the Police need to provide a certificate of annual inspection if it is mentioned on the calibration certificate?

Irrelevant. See below

Short answer - no. Longer answer, not unless they can show that there was a real likelihood that a machine that is presumed to be working correctly wasn't. The calibration being slightly out of date will not do that, and will at best support more persuasive evidence (if you had any).

Absent any "smoking gun" you were saving for a dramatic finale, or other semblance of a viable defence, thr fixed penalty is likely to be the most favourable disposal.

As far as securing a conviction is concerned, no.
I am responsible for the accuracy of the information I post, not your ability to comprehend it.

You can contact the police and point this out to them and ask them to review the action against you. They may discontinue it, but I doubt it.

If not, your choices will be to either decline (or ignore) any out of court offers they may make (of  a course or fixed penalty) and plead not guilty in court.

Whatever it says on the certificate, your task in court will be to convince the Magistrates that the device cannot be relied upon to show that you exceeded the speed limit. An expired calibration certificate by itself will not do that. Mechanical devices are assumed to be working correctly unless the contrary can be shown and they do not suddenly become unreliable the day after their calibration certificate expires.

Whatever you decide to do, you must respond to the request for driver’s details within the 28 days allowed.

...Therefore of the 3 possible options...

It's not 3 options. It's 2 options, which are:
1) the calibration at the factory (lasting 3 years)
2) the calibration on site (lasting 1 year, which is why after the initial one they gave it an annual update)

You were caught within 1 year of the last on site calibration, and within 3 years of the last factory calibration, so it's not out-of-date. Not that an out-date-date calibration is likely to matter anyway.

Whatever you decide to do, you must respond to the request for driver’s details within the 28 days allowed.

OP already has a COFP, so I think it's safe to say they replied to the request for driver's details. The timeline to respond to the COFP may be a bit more pressing

Sorry, missed that. Thanks for the correction.
