The cost of achieving net zero housing will add to inequalities in the UK

The UK’s housing market suffers from yawning regional inequalities over both the condition and price of homes—and the challenge posed by the need to reduce greenhouse gas emissions from domestic property threatens to further accentuate those divisions.

Housing accounts for almost a third of UK CO₂ emissions, so hitting the UK Government’s target of net zero greenhouse gases by 2050 will require a major improvement in the energy efficiency of the country’s housing stock. In 2019 the UK’s Climate Change Committee (CCC) said the overall target would not be met without the near-complete elimination of greenhouse gas emissions from UK buildings. And since 80% of homes in the UK in 2050 are likely to be ones that are already built, retrofitting and insulating these will have to be the main focus of any efforts. According to the CCC, the cost of insulation alone will be £55 billion at today’s prices.

As a first step, the UK government wants all homes to meet a minimum level of energy efficiency by 2035. London currently has the highest proportion (38%) of its housing stock meeting that ‘C’ standard or higher, followed by the South East. In contrast, just 29% of the housing stock in the West Midlands achieves that level. This alone means different challenges for different regions.

But the cost of change will also vary, according to such factors as the existing age and condition of the housing stock. Analysis by Oxford Economics shows that the level of investment required across different regions of the UK will differ enormously. As the chart below shows, households or landlords in Yorkshire and the Humber, Wales, and the West Midlands face the highest bills for retrofitting, while those in Northern Ireland, Scotland, London and the South East will have to stump up the least.

Furthermore, some of the UK’s least efficient housing is located in areas with lower levels of household income. Residents of these more inefficient properties are already likely to be paying higher energy bills than they would if their properties were improved. Yet they may be less able to afford to pay for renovation work.

This situation is likely to get worse. Our forecasts indicate that household incomes are likely to grow more slowly over the next decade in some of the areas that already have both relatively low incomes and the least energy-efficient homes. Examples include Gwynedd in Wales and Pendle in the North West. A key issue will be whether homeowners, tenants, and landlords will be willing and able to pay these costs.

To offset the highest costs falling on those least able to pay, the UK government must devote serious attention to offsetting the different regional cost burdens of improving domestic energy efficiency, to avoid accentuating regional inequalities and undermining its own ‘levelling up’ agenda.

This problem is not unique to the UK—there are also large variations between nations. Oxford Economics’ new index of real estate obsolescence suggests that Nordic countries are best placed within Europe in terms of the scale of housing challenge, while Central and Eastern European countries such as Czechia and Estonia have the steepest hills to climb. But for all nations everywhere, the time to start is now.

The urgent need to address nature loss implications for agriculture and beyond

Our society and economy are deeply intertwined with nature, but human activity has pushed nature into crisis—one-third of the world’s forests are gone, the rate of species extinctions is accelerating, and scientists have issued stark warnings about the rapidly declining health of ecosystems. At the heart of this crisis is a profound irony: we are jeopardising the very systems upon which our life depends.

To bee or not to bee—a small insect’s place in the world economy

In recent years, UK government figures have pointed towards a long-term decline in bee populations, and perhaps more worryingly, a study in the US found a decline in the honey yield per colony due to environmental degradation. Given this concerning evidence, World Bee Day was established by the UN General Assembly in 2017 to highlight the important role bees and other pollinators play in global food production, and how vital it is that we support them.
