Has anyone received a letter for spending camera on A4 great west road j/w Sutton lane  W/B TW5 (5003)

I was doing 36mph but I thought that road is 40mph !
Shall I notify them it was me or challenge them first
Any info greatly appreciated?

As above, you must reply naming the driver.

The only way you can then "challenge them" is to ignore any offer of a course or fixed penalty, and plead not guilty when the matter goes to court. Unless you have a valid defence which you have not shared with us, that will result in a finding of guilt, three points on your licence, and a fine and costs approaching Ł1,000.

Out of interest, what made you think that road was subject to a 40mph limit?

I don’t use that road very often but i thought it was 40mph correct me if I am wrong,

To be fair - it used to be a 40 (and 'feels' like a 40).  But the clues that it's a 30 is no speed signage and a system of street lighting which makes it a 'restricted road' which is 30...

This is my first speeding ticket since i started driving at age of 18 .
Getting old now at 51

Well at least you'll be offered a course to avoid the points...

It’s poorly sign posted

It's not sign posted at all and it has a system of street lighting. That's what makes it a 30mph limit.

So I believe they dint bother with a sign just to catch drivers out and fill there pockets.

It seems you didn't read the link I posted.  There are 30mph terminal signs - it seems you simply missed them.

30MPH SIGNS

If they didn't 'bother' with signs then you may have a defence…

It’s 40 all way from Hammersmith to Heathrow
Airport the only part at 30 is that traffic light . So I believe they dint bother with a sign just to catch drivers out and fill there pockets.

The Treasury’s pockets, not theirs.
