Overview of the Report and Its Origin
The report “A Green Stimulus for Housing – The Macroeconomic Impacts of a UK Whole‑House Retrofit Programme” is published by the New Economics Foundation, a charitable think‑tank noted for independent research on social and environmental policy. It is authored by Donal Brown (research fellow at the Universities of Leeds and Sussex and Sustainability Director of the Sustainable Design Collective), Hanna Wheatley, Chaitanya Kumar and Joanne Marshall (who performed housing stock modelling for Parity Projects). The study was released in July 2020 and analyses a four‑year, £85 billion government‑backed retrofit programme for UK homes.
Scope and Ambition of the Green Stimulus
The proposal targets the retrofit of roughly 9 million UK homes, aiming to cut domestic energy demand by about 15 % and reduce household emissions by 21 % of the 2019 baseline. It seeks to create a substantial green jobs boom, with 117 811 new direct jobs in the first year rising to a peak of 382 885 in year four, averaging 294 527 new construction jobs annually and an additional 220 630 indirect jobs each year.
Economic Impact and GDP Boost
Modelled outcomes indicate that annual GDP would be 1.58 % higher (≈£36.34 billion in 2019 prices) in 2023/24 compared with a no‑intervention scenario. Direct and indirect employment effects together could sustain an average of 515 157 new jobs per year between 2020 and 2024, representing a 22 % rise in total construction employment and a 162 % increase in the renovation, maintenance and improvement sector.
Energy Savings and Household Benefits
The programme projects average annual energy‑bill savings of £418 per retrofitted home, totaling £3.76 billion in 2023 alone and cumulative savings of £53.17 billion by 2035. Energy‑demand reduction measures would contribute a 10 % cut, low‑carbon heat a further 4.4 %, and micro‑generation (mainly rooftop solar PV) an additional 7 % reduction, together achieving the 15 % overall target.
Emissions Reductions and Climate Goals
Retrofits are expected to cut CO₂ emissions by 19.23 Mt CO₂ per year by 2023/24, amounting to 21 % of 2019 UK home emissions, and a cumulative 40.9 Mt CO₂ by 2023/24. This would exceed the fourth UK carbon budget and support the nation’s net‑zero objectives for 2050.
Policy Instruments and Funding Structure
The central Scenario 3 combines public financing (£100.15 billion total) with green mortgages. It includes £22.19 billion in low‑income grants, £46.25 billion for able‑to‑pay schemes, and £16.91 billion in green mortgages. Additional policy costs cover a £6.4 m National Retrofit Taskforce, £250 m innovation fund, £200 m skills and training, £216 m area‑based delivery, and £5.19 bn in reduced VAT, totaling about £6.45 bn. The programme is projected to be self‑financing, delivering a net government revenue gain of £25.6 billion over four years.
Implementation Measures and Workforce Development
Key actions include establishing a National Retrofit Taskforce, area‑based delivery models, building renovation passports, and one‑stop‑shop business models. The plan calls for a £50 m annual increase in construction‑industry training, a £250 m innovation deployment fund, and the introduction of variable Stamp Duty and reduced 5 % VAT on retrofit works to stimulate demand.
Long‑Term Outlook and Sustainability
Beyond 2024, the report recommends extending the retrofit agenda to 2030, raising EPC standards to C (or higher) for all homes, phasing out fossil‑fuel heating, and institutionalising area‑based delivery. The analysis underscores that a coordinated green stimulus can simultaneously address economic recovery, job creation, energy affordability, public health, and climate mitigation across Europe, offering a replicable model for sustainable housing transformation.
