So far some 330,000 have been ordered under the scheme. However, with a limit of 400,000 vehicles which can be scrapped, a further 70,000 people could still take advantage of the deal.

The Government have said that manufacturers had requested the extension until the end of March 2010 to allow them to prepare for the exit phase. However, there will be no additional financing for the scheme, which is funded by the Government and 38 car manufacturers.

Mandelson said: “Against the background of the economic downturn the scrappage scheme has proved a great success, driving UK car sales, protecting jobs and supporting the supply chain manufacture at a time when this sector needed it most.”

The Society of Motor Manufacturers and Traders (SMMT) says the scheme has accounted for a fifth of new car sales since it was introduced, but warns of a tough year once it ends.

Of the 158,082 sales last month, 21.6% were attributable to the car scrappage scheme, which is due to end in February or when funds run out, whichever is sooner.

CEO of the Society of Motor Manufacturers and Traders (SMMT) Paul Everitt, said: “The increase in new car registrations in November reflects the positive impact of the scrappage incentive scheme, customers avoiding the VAT increase in January and the very difficult conditions that we experienced a year ago.”

After Business Secretary Lord Mandelson said last week that the industry would have to cope with returning to normal market conditions, Everitt urged the Government to consider extending the scheme in its Pre-Budget report on Wednesday, noting that there was just an estimated £125m of funding remaining.

The November figures took new vehicle sales to more than 1.84m for the first 11 months of year, but this represents a drop of 8.8% on the same period last year. Full year estimates are for 1.95m sales versus 2.13m in 2008.

RAC motorist strategist Adrian Tink said: “We are still concerned about what will happen once the scheme ends and the discount bubble burst.” 

Edmund King, president of the AA noted of the new cars purchased through the scheme: “These cars are cleaner, greener and safer”, whilst making reference to a recent poll suggesting 13% of drivers would consider buying a new car if the scheme was extended.

UK manufacturing leader at Deloitte, David Raistrick said: “We may see interest rates increase next year. Furthermore, car manufacturers may find themselves needing to implement price rises due to the low value of sterling increasing the cost of imported cars and parts. The automotive sector must be prepared to deal with these challenges in order to ensure a long-lasting recovery.”

Mandelson - No Promises

“If the scheme ends in October and is followed by a 2% increase in VAT in January it will be a serious blow to the British car industry that’s just getting back on its feet.” warns Paul Everitt, CEO – SMMT.

Executives from the motor industry met with Business Secretary Lord Mandelson last week and called for an extension to the Car Scrappage Scheme by increasing the Government provided subsidy by a further £200m. The initial Government sum which kick started the Scrappage Scheme in May was £300m and is forecast to run out in October.

The industry is warning that failure to provide further subsidy may result in workforces being forced back on to shorter working weeks with job security at risk.

Paul Everitt, Chief Executive of the Society of Motor Manufacturers and Traders (SMMT) was quoted to have said “Without an extension there’s a real risk of an abrupt slump in sales that will create further uncertainty for thousands of car workers with the likelihood of short-time working.”

A Department of Business spokesman confirmed a meeting was to take place, but said there were no plans to extend the Car Scrappage Scheme.

Since the Car Scrappage Scheme was launched in April 2009 around 200,000 new cars have been bought, which has helped to sustain employment within and connected to the motor industry.
