Terms of service

LAST UPDATED · AUGUST 2026

Who you're contracting with

Karen is a trading name of Spark Light Fire Ltd, a company registered in England and Wales, company number 17326372.
Registered office: 33 Khartoum Road, London, England, SW17 0JA.
Queries and complaints: ewandickie@sparklightfire.co. We aim to reply within three working days.
Your contract for the service is with Spark Light Fire Ltd. "Karen" is a product name, not a legal person.

Karen is a software service that helps the registered keeper of a vehicle challenge a private parking charge in the UK.
Karen is not a law firm, is not regulated by the Solicitors Regulation Authority, does not provide legal advice and does not provide legal representation. Nothing Karen writes is a substitute for advice from a solicitor.
Karen prepares and sends correspondence in your name, with your approval. You remain the appellant throughout.

That you are the registered keeper of the vehicle, or are authorised by them to act.
That the account you give of what happened is true. Karen argues only what you tell her; a false account can lose an otherwise winnable case.
That the documents you upload are your own.

Three tiers: Karen £19, Firm Karen £29, Nuclear Karen £39, one charge per case.
Payment is taken in full when you activate your case. There is nothing further to pay however the case ends.
You are paying for Karen to build and run your case — the full legal analysis, the appeal, and the chasing. Roughly half of properly challenged charges get cancelled, but nobody can promise yours will be.
The fee buys Karen's work on your case, not a result. No outcome is guaranteed.

No outcome is guaranteed. Operators and adjudicators decide cases, not Karen.
On the Nuclear tier Karen prepares your court papers and shows you exactly how to file them. She does not file them for you and cannot represent you in court.
Deadlines matter. If you give Karen a notice close to or past its appeal deadline, some routes may already be closed.

Approve drafts and forward anything the operator sends you, so the record stays complete.
Photograph signage promptly when Karen asks. Operators change signs and that evidence disappears.

Under the Consumer Contracts Regulations 2013 you have 14 days from purchase to cancel a service bought online and receive a full refund.
At checkout you may expressly ask Karen to begin work within those 14 days and acknowledge that you lose the right to cancel once the service has been fully performed — that is, once your appeal has been filed. We record that request and the time you made it.
Full refund if Karen does not file your appeal.
No refund because the operator refuses the appeal. That is the outcome we do not guarantee, and the fee pays for the work rather than the result.

Karen is not a law firm and does not provide legal representation.
