The £26bn Green Tax: Landlords face massive retrofit bill to meet government's 2030 energy targets

• New analysis from Just Landlords reveals over 3 million private rental properties yet to meet government target
• Upgrade costs in some areas exceed annual rental income by nearly 50%

Landlords across England and Wales are facing a staggering £26 billion hurdle to meet the government's 2030 energy efficiency deadline.

New analysis, from specialist landlord insurance provider Just Landlords, reveals that 3.38 million properties currently fall short of the proposed targets, with upgrade costs in some regions exceeding the total annual rental income by almost 50%.

Under the government's Warm Homes Plan, all tenancies are required to have a minimum EPC rating of C by 1st October 2030. While the average cost to upgrade a non-compliant property stands at £7,633, the figures vary considerably, with rural and northern regions facing costs as high as £12,000.

Comparing the cost of green upgrades to the annual earning potential of a property, Just Landlords has calculated a 'repair-to-rent ratio', to see how long it will take landlords to fund essential retrofit works.

In Powys, where 83% of properties are currently non-compliant, the average bill to reach Band C is £10,759. With average annual rents in the area at just £7,248, landlords face an upgrade cost equivalent to 148% of their total annual income.

Areas with Highest Repair-to-Rent Ratio

1. Powys - 148%
2. Hartlepool - 138%
3. Isle of Anglesey - 135%
4. Gwynedd - 131%
5. Northumberland - 129%

In a stark contrast, thanks to higher rental prices, landlords in London can cover retrofit costs with just a few weeks of their rental income.

Areas with Lowest Repair-to-Rent Ratio

1. Kensington and Chelsea - 20%
2. Westminster - 22%
3. Islington - 25%
4. Hammersmith and Fulham - 25%
5. Camden - 26%

This clear divide between regions continues when looking at current compliance levels, with the majority of the most compliant regions being found in major cities and urban areas.

Most Compliant Regions

1. Tower Hamlets – 66% compliant
2. West Northamptonshire – 55% compliant
3. Southwark – 53% compliant
4. Bracknell Forest – 51% compliant
5. Islington – 51% compliant

Meanwhile, in more rural and coastal areas, the vast majority of homes require immediate investment.

Least Compliant Regions

1. Isles of Scilly – 90% non-compliant
2. Ryedale – 88% non-compliant
3. Isle of Anglesey – 87% non-compliant
4. Burnley – 85% non-compliant
5. Pendle – 85% non-compliant

As well as reporting higher levels of non-compliance, many of these regions also represent the highest physical risk, with over half of properties currently having EPC ratings of E, F or G. These 'deep retrofit' areas require major structural interventions, such as solid wall insultation and heat pumps.

Deep Retrofit Regions

1. Isles of Scilly - 70%
2. Isle of Anglesey - 60%
3. Ryedale - 57%
4. Eden - 56%
5. Powys - 52%

Kimberley Kealing, Managing Director of Just Landlords, comments: 

"While the drive towards more energy-efficient homes is a vital step towards Net Zero, it involves a massive financial burden for landlords. Shockingly, our data reveals that for many landlords, the cost of renovations could exceed their annual rental income by nearly 50%. Without significant support, this 'green tax' could leave landlords questioning the financial viability of their properties."

"From an insurance perspective, this national renovation project carries its own risk. Major works can increase a property's risk profile, with a higher chance of claims related to things like structural damage, escape of water and fire. Landlords in these 'deep retrofit' areas must ensure their coverage is tailored for the scale of works being undertaken."
