Our Peddimore proposals

We are proposing to expand our UK operations with the development of a new manufacturing facility in the West Midlands.

ROCKWOOL has purchased 114 acres of land at the Peddimore site, north of Minworth, to the north east of Birmingham, which has already been designated specifically for manufacturing use and has outline planning permission.

In July 2026, we submitted our set of Reserved Matters planning applications for the facility to Birmingham City Council. We anticipate a decision from the Council in the second half of 2026.

The submission of this set of ‘Reserved Matters’ applications follows the Council’s approval of a ‘Section 73’ application during 2025, which amended elements of the site’s existing planning consent to accommodate specific elements of ROCKWOOL’s proposed development.

Investing in UK production

If approved, Peddimore would be our second UK stone wool production facility alongside our existing South Wales plant, where we are also continuing to invest for the long term.

Our proposed state-of-the-art manufacturing facility, featuring proprietary electric melting technology, would boost supply capacity for UK and Republic of Ireland customers, whilst also supporting ROCKWOOL’s ambitious global sustainability plans.

This would create skilled, long-term jobs and local supply chain opportunities, as well as support the UK’s net zero targets and a safer built environment through ROCKWOOL’s stone wool product portfolio.

Peddimore site comes with outline planning permission

The Peddimore site is included in Birmingham City Council’s Development Plan. It has been designated specifically for manufacturing use and has had outline planning permission since 2019.

Key infrastructure, including a new access road and roundabout into the site, is already in place, servicing an adjacent warehousing facility built in 2023.

Our planning applications

We have adopted a two-step approach to the planning process to ensure compliance and alignment with local planning policies and conditions, as well as the site’s existing designation and planning status. 

Step one – February 2025

Our proposals were generally align with the 2019 outline planning permission for the Peddimore site, but we sought to make some changes to the approved drawings, in particular to adjust maximum permissible building height limits.

We submitted our Section 73 planning application to Birmingham City Council in early February 2025. The application has now been approved by the Council.  

You can view and download these Section 73 application documents from the section below.

Step two – Spring/Summer 2026

In April/May 2026, we consulted local communities on our Reserved Matters application before submitting the set of Reserved Matters applications to Birmingham City Council in July 2026.

We carefully considered the comments from local residents and stakeholders and have incorporated them into the final proposals.

This set of applications included the detailed proposals for the new facility, such as building design and appearance, site layout, access arrangements, and landscaping. This now completes the full planning process.

Due to the requirements of the Council’s planning process, the Reserved Matters process is split into five separate applications, consisting of the main Reserved Matters submission and four supporting ‘Discharge of Conditions’.

These four supporting applications deal with specific planning conditions that primarily apply at this Reserved Matters stage. The additional applications cover topics such as drainage, highways, landscaping and environmental matters, all of which were included in the Reserved Matters pre-application consultation materials.

You can view and download the key Reserved Matters and discharge of conditions application documents from the section below. The full documents are available on Birmingham City Council’s website.  

Job and supply chain opportunities

If our Reserved Matters proposal is approved, the facility could become operational in 2030.

This would create good quality jobs and training as well as supply chain opportunities for local people and businesses. Whilst it is still early in the process, we’re always keen to talk to people who might be interested in working with us in connection with these opportunities.
