Beyond compliance: Why UK housing regulation fails our health

Housing is one of the most powerful public health interventions we can make. The rules governing how we design and build homes should actively promote health, but instead, the UK’s regulatory framework remains largely defensive – designed to avoid the worst outcomes, rather than promote the best. And while there are some innovative developers leading the way, across the sector, it is compliance, not true well-being and measurable benefits, that has become the benchmark.

The problem is structural and widespread. UK building regulations approach health in silos, treating ventilation, thermal comfort and safety as separate issues rather than interconnected determinants of well-being. Part F focuses narrowly on air-exchange rates, focusing on mechanical ventilation systems but with no requirement for real-time air quality monitoring or occupant feedback.

Part L rightly pushes energy efficiency, but without sufficient safeguards for ventilation, moisture management or material safety, encouraging airtight, pollution- and condensation-trapping interiors. Meanwhile, the Decent Homes Standard – with compliance now not expected until 2035 – remains rooted in outdated assumptions and does not reflect modern research on the full range of health risks associated with housing.

The result? Thousands of new homes are still being built year after year that are technically compliant, yet demonstrably bad for our health. What’s currently missing is a cohesive, health-led framework that is widely adopted across the sector. There currently isn’t universal consideration of how air quality, overheating risk, daylight, acoustics and materials interact to affect sleep, respiratory health, stress or cognitive function. Nor is there any obligation to assess their combined impact on occupants over time.

EPCs have been in use since 2007, yet no mandatory health equivalent has existed to date for the health-related aspects of a home. HHCs (healthy homes assessments carried out using the Healthy Homes Checklist tool) are an important new metric coming into play that address this fundamental regulatory and assessment gap.

This regulatory gap is compounded by delivery models that prioritise financial return and quantity over quality or long-term health outcomes. Fewer than 40% of developers undertake Health Impact Assessments, largely because there is no statutory requirement to do so. Where health-related standards do exist, they are often treated as compliance checklists, rather than design imperatives. Health becomes something to be “managed”, not actively designed for.

A 2023 review by the Building Research Establishment found that current building standards fail to address key contributors to respiratory illness, mental health decline and sleep disruption – even when homes meet regulatory requirements. Substandard housing is estimated to cost the NHS up to £1.4bn annually – much of it linked to damp, mould and inadequate ventilation.

Internationally, the UK is falling behind. France’s RE2020 regulation mandates indoor air quality thresholds for CO₂, PM2.5 and VOCs, alongside overheating resilience. Denmark embeds daylight, ventilation and indoor air quality – down to limits on nitrogen dioxide – into residential design codes. By contrast, the UK’s Future Homes Standard remains predominantly focused on carbon reduction, with no binding metrics for mould risk, air toxicity or other health-related indicators. As the UK Green Building Council has warned, we are at risk of delivering zero-carbon homes that are not zero-harm.

Even where standards exist, enforcement is inconsistent. Post-occupancy evaluation is rare, meaning buildings can be signed off while performing poorly once lived in. And there is no systematic way to measure, track or report the health impact of new housing.

Regulation sets the floor, not the ceiling. What’s needed now is a shift in mindset: from avoiding failure and fixation with sustainability to actively promoting health. We already have the knowledge, tools, and precedent to build differently. What’s missing is alignment – between housing, planning and health policy – and the expectation that health is a core outcome of housing delivery, not a by-product. We need HHCs as much as we need EPCs – with transparent communication to residents on the health status of their home.

The next generation of developments should not just delivery numbers and meet minimum standards but aim to create truly healthy homes with measurable health outcomes.
