Warm Homes Plan – Windows Not Included

The Warm Homes Plan has been published and the government has made it quite clear that private households will not get any contributions towards windows and doors.

References to windows and doors within the policy document are limited to local authority-led and social housing funding routes.

The Glass & Glazing Federation has still called for clarification from the Department for Energy Security and Net Zero on how building fabric improvements will be supported under the scheme.

 

The Plan

The Warm Homes Plan has been described by the government as the largest home upgrade programme in British history. It will provide significant investment in insulation, low-carbon heating and renewables. Grants will be issued on zero or low-interest, loan-style support for measures such as batteries, heat pumps and solar panels.

The GGF says that while it supports actions that help households cut energy bills and carbon emissions, it is seeking greater clarity on where fabric-first improvements sit within the overall framework.

The GGF says it has contacted the director of the Department for Energy Security and Net Zero to request urgent clarification on how fabric improvements will be treated under the Warm Homes Plan and whether future guidance will enable homeowners and social housing providers alike to upgrade existing glazing as part of a whole-house retrofit approach.

 

Fabric first

Chris Beedel, the head of government advocacy and stakeholder relations at the GGF, says: “While we recognise the government’s focus on electrification and renewables, we believe that energy efficiency must start with the building fabric.

“Windows and doors play a critical role in reducing heat loss and ensuring that low-carbon technologies such as heat pumps can operate effectively.

"We are seeking clarity from Government on how these essential measures will be supported.”

The GGF is said to be ‘cautiously optimistic’ that opportunities will be presented for the glass and glazing sector, particularly within the social housing and local authority-led retrofit programmes. However, the Federation stresses that further detail is needed to understand the scale and scope of these opportunities.

 

GGF committed

Beedel adds: “The GGF looks forward to further engagement with DESNZ and to the additional detail promised in forthcoming policy updates. We are committed to working constructively with government to ensure the Warm Homes Plan delivers practical, effective and inclusive energy efficiency solutions that fully recognise the value of fabric-first improvements.”
