So many experts across the private rented sector are damning the government’s Green scheme’s considerable shortcomings due to the banning of new gas boilers from 2035 and making available £5,000 grants to install heat pumps, which the government campaign states is the best alternative.

Next year landlords and owner occupiers will be able to apply for £5,000 grants from April with the government’s plan to drastically increase numbers of heat pump’s manufacturing and to pay towards their installation; the cost can be as high as £16,000 each.

David Adams, spokesperson for the Green Stamp Duty Incentive Energy Efficiency Infrastructure Group, says: “Whilst support for the installation of circa 30,000 per annum heat pumps for the next three years is welcome …. we must see bolder measures than those outlined today.

“The current issues facing the retrofit market – the lack of accredited installers, patchy nationwide provision of green measures and the skills gap – are rooted in an uncertainty around the market’s longevity born out of the grant-driven boom-bust past history.

“Without also instigating a long-term driver of demand, the progress made through this boiler upgrade scheme will collapse again when the three years are up. We mustn’t repeat the experience of the past insulation and photo voltaic programmes which didn’t produce a lasting legacy of delivery capability and where home retrofit has returned to a niche activity.”

The group is pushing the government to introduce a stamp duty incentive for owners and landlords to ‘retrofit’ energy efficient heating. Recently held research states that people are less likely to take up the option as only one is six polled are considering installing alternative heating in the next five years.

Ross Counsell, chartered surveyor and director of a property sales company, says there £5,000 sounds very positive but it is simply not enough sufficient.

Counsell says: “You just have to look at the poorly thought out Green Homes Grant which left administration costs of over £1,000 for some homeowners according to the National Audit Office. For many low-income families, this sum is extremely damaging and sees just how poorly thought out and underfunded these schemes have been.

“Furthermore, the current energy crisis has starkly demonstrated just how lagging the UK is on future-proofing homes from fossil-fuel dependency. Unfortunately, the lack of government investment in insulation and heat-pump technology means the UK has some of the oldest and leakiest housing stock in Western Europe.

“The initiative of these efforts to future proof homes is a step in the right direction for the government. However, a concise roadmap to phase out new boilers out by 2035, with significant funding would have been much more effective.”

An independent climate think tank also agrees that the fund is not enough and claims the government’s 2035 phase-out date for new fossil fuel boilers is "a world-leading achievement". but the funding offered by the government is insufficient.
