According to the firm, late plate, low mileage LPG vans are making up to 20% more than diesel counterparts with petrol models, which can be converted to LPG, making the same as diesel for the first time ever.
Alex Wright, group commercial vehicle manager at Manheim, said: 'We are seeing great demand for LPG vehicles, especially the new Transit, at our Colchester site. Due to demand, there is currently a massive shortage of alternative fuel vehicles at auction.
'Buyers in the London area are willing to purchase nearly- new LPG vans at the same price as new vehicles and are welcoming the advent of alternative fuel vehicles.'
He added that at the older end of the market, diesel was still the dominant force as buyers trust the durability of the engines more than LPG units. It would take time for buyers of older vans to accept the alternative fuel.
Wright said: 'It will be some time before confidence about LPG builds, especially among the key market of the self-employed. This sector of the market will continue to buy diesels because of the well-documented benefits.'
However, congestion charging has no marked effect on the residuals of LPG-powered cars, according to CAP and Glass's.
