Debt Collection Letters
In the vast majority of cases this is not SCS but people using their headed paper for debt collection purposes.
What to look for is who the letter tells you to pay. In this case it is neither the parking company or the solicitors themselves but a debt collection company. Clear example of the SCS letterheads being passed out to all and sundry. Reputable solicitors generally do not allow this so you may want to complain to the Solicitors Regulation Authority about misleading statements / lack of oversight by SCS.
Another reference to Debt Recovery Plus in this one. Since the debt collector cannot instruct the solicitor to issue a court claim, this again looks like headed notepaper being passed out to anyone that asks. Ask SCS to clarify who has given them the authority they claim. If need be complain to the Solicitors Regulation Authority about misleading statements / lack of oversight by SCS if you don't get a clear answer.
Letter before County Claim
Sometimes there is a letter like this which can be replied to - in other words treat it as if it came from the solicitor - but only reply to the parking company with a copy to the solicitor. Get advice beforehand though as only the parking company can instruct the solicitor.
