I recently insured my SLK online with Barclays Insurance, after 3 days I went online to tax it to find the insurance had not been registered. When I contacted Barclays Insurance they said the insurance details would not be placed on the insurance database until 5 or 6 days after I took out the insurance. I am therefore paying for a weeks insurance when I am unable to use the car. Nothing on their website stated this delay. I am taking this further but thought I would warn anyone else not to use this company if they need to tax their vehicles inside a week!
