Next steps to zero carbon homes: allowable solutions

This consultation seeks views on a pragmatic, flexible way to help house builders meet the zero carbon homes standard by reducing some carbon emissions ‘off-site’.

Last fetched 03 May 2026 · gov.uk
Detail

The government recognises that it will not always be cost-effective, affordable or technically feasible for house builders to reduce all carbon emissions through on-site measures, like fabric insulation, energy efficient services, and/or renewable energy generation (eg solar panels).

This consultation sets out and seeks views and further evidence on the main principles, price cap and processes for the delivery of ‘allowable solutions’ - off-site projects or measures that reduce carbon emissions - which house builders may support to achieve the zero carbon homes standard.

We are also publishing a development stage impact assessment alongside the consultation. The response form to enable you to comment on the consultation document is available for download below.

The government is committed to implementing zero carbon homes from 2016. The zero carbon homes standard will require house builders to decrease all carbon emissions from energy arising from fixed heating and lighting, hot water and other fixed building services (eg ventilation) in new homes. It does not include carbon emissions from appliances or ‘white goods’.
