Because it only uses cars on an ad-hoc basis, it decided that daily rental was the best option when employees had to travel on business.
The solution also helped tackle the issue of congestion charging, which has affected all London-based businesses since the £5-a-day toll was introduced last year.
While large businesses have systems and employees dedicated to managing their vehicles, smaller companies and businesses, including Zig Zag, do not.
Mia Fern, chief operating officer, said that meant that, although daily rental may be a good option, high service standards were required.
She said: 'With the type of work that we do we often have to interview celebrities off-site. These sometimes have to be organised at the last minute, meaning the team and all of our equipment have to be on the road within half an hour. It is my job to ensure we take everything we need and get to the location on time.'
The team turned to Enterprise Rent a Car, which has introduced a free customer pick-up and drop-off service to take drivers to their rental car outside the zone, so they do not have to pay the charge.
