I have been in the same situation except I was the driver of the uninsured car (I never got caught out like that again, and I suspect you won't either).
Do not ignore the letter. Do not listen to people telling you to ignore it - it is terrible and ignorant advice. New Flash: Problems and bills don't go away by ignoring them.
You have received a stock standard letter. The other insurance company simple wants to know who to negotiate with (ie who send the bills to should everyone agree that the other party was not at fault and who to send the money to should everyone agree the opposite) - be that you, your insurance company (if you were insured), the driver of your car or your rich daddy who bails you out of trouble if you are lucky enough to have one of those.
As earlier stated, you need to write back explaining who the driver was and that the insurance company should talk to them (do not say that the driver is "liable" for costs, but simply state who was responsible for and driving the vehicle at the time of the crash).
If no one talks to them next step for the insurance company is to take it to court and with no better information the claim will be lodged against the registered owner. If you fail to show up in court you will be found guilty by default. Ignoring the letter is irresponsible and ignoring your duty to not only yourself but as a citizen and is a guaranteed way to have bailiffs turn up on your door step. You will end up paying unnecessary court costs, bailiffs fees and interest when your friend should have manned up and simply paid for their mistake in the first place. The insurance company doesn't want to go to court, they simply want to work out a deal that is just.
Legally the driver is responsible for losses that they cause. It is not the owners fault it was crashed, it is the drivers fault. The at-fault driver is responsible for losses to BOTH cars, so from a legal standpoint, you of all people should not be left out of pocket.
Igor the earlier obfuscation about WOF's etc. The physical act of speeding, driving with no WOF or crashing is what is illegal. It is not illegal to own a car that has no WOF, that can speed or that can crash.
Agreed, bury your head in sand hoping it will go away wouldn't help you. Be proactive and provide all the information (proof) to the insurance company who's the responsible driver at the time is the only way out from here.
