The Federation of Master Builders

H+H UK Ltd

H+H is the largest manufacturer of aircrete blocks and associated products and services in the UK, including the Thin-Joint build system using Celfix mortar. It is the company behind the more commonly known Celcon Blocks.

Unlike other manufacturers H+H specialises in aircrete and nothing else. There isn’t a question about building with aircrete blocks that the company’s well established and helpful technical department could not answer.

Based in Yorkshire and Kent the company has three manufacturing sites in the UK employing around 350 people, from new apprentices that have been with the company for a few months to the technical director, the font of all knowledge when it comes to building with aircrete, who has been with the company for more than 30 years.

H+H is a company that understands builders and buildings making it the ideal firm to work with regardless of the size or scale of your project. Given the usability of H+H’s blocks they are suitable for use in all building types, from extensions to conversions and complete new builds. The company also has a block for every aspect of building: 

• External solid walls
• External cavity walls: inner and outer leafs
• Partition walls
• Separating and flanking walls
• Solid foundations
• Beam and block floors
• Infill to steel and concrete framed buildings

H+H even has its own in-house thin-joint demonstrators, Owen and Andy, both former builders who will happily visit you on site to offer help and instruction.
