Summary

Originally built in 1877 and converted for retail use over twenty years ago, Trinity Chapel in Blaenau Gwent underwent a major transformation into a modern, decarbonised Library and Adult Education Centre. The heating retrofit was completed between January and September 2024, with the site reopening to the public in October 2024 under Aneurin Leisure Trust.

Our support

Funding application support, technical guidance on low carbon heating systems, and coordination with council and leisure trust teams.

Technology solution

  • 4 air source heat pumps (34 kW total output).
  • Wet underfloor heating system.
  • Electric point-of-use water heaters.
  • Thermal insulation to solid walls.
  • Upgraded electrical connection to the National Grid.

Investment

  • £206,778 from the Local Authority Low Carbon Heat Grant (90% of project costs), with additional funding from the Welsh Government’s Cultural Transformation Fund, UK Shared Prosperity Fund, and Blaenau Gwent County Borough Council.

Impact

  • Estimated 1,790 tCO₂e saved at implementation.
  • Supports a whole-building decarbonisation approach, enabling future energy generation and storage upgrades.

The environmental targets for Trinity Chapel align very closely with the Trust. This started as a project to do the right thing. Everyone wants to cut their energy consumption. Over the years, and with the energy crisis, this has evolved into making our buildings more sustainable and cost-effective. It’s a win-win all round.
