A petrol station at Costco in Bushey has opened this week.

The forecourt becomes the wholesaler's 17th in the country with fuel available exclusively for Costco members.

Drivers have to scan their membership card before fuelling at the pumps. There are 30 pumps available which are pay-at-the-pump.

Both petrol and diesel is available with Kirkland Signature Fuel Costco's official supplier.

Unleaded fuel is currently available at £1.36 per litre and at £1.38 for premium diesel.

The petrol station will be open on Monday to Fridays from 6am until 9.30pm, on Saturdays from 6am-8pm and on Sundays from 7am to 6pm.

Many members have already been making use of the spacious new forecourt which can be accessed via Costco's existing entrances.

To accommodate the new petrol station, Costco's existing car park has been reconfigured but the total number of spaces has increased by more than 100 to over a 1,000 thanks to a new car park over two floors.

Costco, which is headquartered at the Bushey site, says new charging points have also been introduced to the car park.
