When was "the other day"?
The applicable provisions are here:
An Act to consolidate certain enactments relating to road traffic with amendments to give effect to recommendations of the Law Commission and the Scottish Law Commission.
I don't think the golf club reception would qualify as "
any person having reasonable grounds for so requiring", so it seems to me that you are under a duty to report the accident to the police. Despite the wording of the act requiring this to be done in person, many forces now allow you to report the accident online. There is normally a form on the local force's website to report damage-only accidents.
As long as you're prompt, the police are unlikely to care that you missed the 24 hour cut-off by a few hours.
