Over 6,000 householders have so far applied for £400 vouchers under the London Boiler Cashback Scheme, with new applications coming in every day.

News that vouchers are available has been welcomed by the Builders Merchants' Federation (BMF), which obtained the figures showing that the level of enquiries is remaining steady.

In the first four months since the scheme was launched, over 6,000 householders have either applied or are currently in the process of applying. Of these, over 1,200 applicants have submitted claims following the installation of their new, energy-efficient boiler.

Brett Amphlett, BMF policy and public affairs' manager, said: "In an ideal world, it would be better to have a coherent, fabric-first approach to improve the thermal and energy performance of homes. But in the absence of a proper, long-term national policy, it is not surprising that London residents are responding to the Mayor’s offer. We shall continue to track London Boiler Cashback over coming months to monitor uptake and invite the new Mayor of London, Sadiq Khan, to find the money for another offer next winter."

The BMF said it was also pleased to learn that 40% of applicants heard of the offer via their installer - which continues to be the most effective communication route to market for such schemes.
