National Household Model: UK Domestic Housing Energy and Emissions Projections

The National Household Model (NHM) is an open-source tool for projecting the effects of policy and legislative changes on the energy use and emissions of the UK domestic housing stock. It was developed by the Centre for Sustainable Energy on behalf of the Department for Business, Energy and Industrial Strategy (BEIS) and is stored by the UK Data Archive. The model's data was last updated on 2026-07 08.

Use Cases

• Simulating future UK housing stock energy consumption based on policy scenarios described in the model.
• Projecting greenhouse gas emissions from UK domestic buildings based on legislative changes.
• Analyzing the potential effects of energy efficiency policies on the national housing survey data.

Strengths

• Open-source tool under the OGL-UK-3.0 license, allowing for public use and modification.
• Developed by a named authoritative organization, the Centre for Sustainable Energy, for a UK government department.
• Data is stored and managed by the UK Data Archive, a recognized repository.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Model operation requires learning a specialist scenario language based on S-expressions, which adds a technical barrier.
