Readiness and Regeneration:


Getting Walsall Social Housing 2023 Ready Early

One of the most recent of properties to be upgraded in Walsall’s community wide regeneration programme is the 8 storey Hamilton and Woodall blocks. WHG selected Soltherm products to address the challenge of fuel poverty in these tower blocks.

Since 2013, WHG (Walsall Housing Group) have invested over 400 million in home improvements and energy efficiency upgrading. Their core objective is to ensure Hamilton and Woodall and similar properties all contribute towards their  “Readiness 2023” pledge.

Readiness 2023 is a strategy to meet statutory requirements in terms of SAP efficiency (Standard Assessment Procedure for the Energy Rating of Dwellings.) Every property must achieve a minimum a D rating, a year earlier than current legislation requires.

As well as meeting regional SAP efficiency requirements, the project was also expected to contribute to WHG’s ongoing challenge of tackling fuel poverty in the region.

Using the Low Income High Costs (LIHC) definition of fuel poverty, 16.2% of Walsall householders are in fuel poverty, which is 17,030 households. Walsall ranked 9th out of 326 local authority areas in England. Tackling the fuel poverty pandemic in the region is the highest priority for WHG.

Before the retrofit of Hamilton and Woodall, it was estimated 60% of the occupancy were classified fuel poor.

A thermographic survey revealed that the existing cavity fill had failed and would need to be overclad. An External Wall Insulation solution would require procurement to protect the structure and improve energy efficiency for the health, wellbeing and financial security of its residents.

The Project

The decision was made to overclad the tower blocks using Soltherm Ultimate HD Silicone system.

Soltherm Ultimate Silicone EWI system is a BBA approved external wall insulation system incorporating Dual Density Mineral Wool (DDMW) with a silicone render finish, designed to increase a building's thermal efficiency & weather resistance.

The joint installation project would be carried out between SMS and SERS. They were responsible for delivering 5000M2 of the Soltherm EWI system installation to the tower blocks.

the result

Fuel poor occupancy reduced to >10%

Both properties achieved a C rating for Energy Efficiency - Thermal efficiency improvement to 0.28W/mK from < 0.45W/mK.

Project nominated for an INCA award

The successful installation of the Soltherm Ultimate HD EWI system directly reduced fuel poor occupancy to below 20%. The project also achieved recognition in relation to WHG’s Readiness 2023 campaign, with both the Hamilton and Woodall properties receiving a C rating post completion (Thermal efficiency improvement to 0.28W/mK from < 0.45W/mK). This even exceeded the required 2024 standard, 4 years ahead of schedule.

To achieve long term energy efficient living in both properties, Soltherm, SERS and WHG jointly delivered energy awareness sessions to the occupants.

As a result, the total number of fuel poor households has been reduced to less than 10% across both blocks.
