The current price of light heating oil based on a minimum 5,000 litre delivery is about 28p a litre at its summer price, which compares to 50-55p a litre last year and 65-70p in 2013.
British Protected Ornamentals Association chairman Simon Davenport said: "In relation to fuel usage, many growers are now using biomass, so they have not much interest in reducing energy prices at present. As and when prices for biomass begin to reflect other energy costs and demand causes shortage, there may be some response but at the moment there are no plans to slow down the move to 'renewables' i.e. wood.
"Those growers who have not currently invested in biomass will be able to reach improved deals for long term gas supply, for instance. When visiting the growers in the US earlier this year, where there has also been large investment in biomass, one large grower told us that he had been able to reach a very advantageous deal for gas supplies for the next five years and was therefore not investing in biomass."
HTA market information manager Dave Denny said: "The price of oil is coming down and is helping anyone using heat, which is broadly good for the industry."
