H+H UK Limited is committed to the protection of the environment.
H+H UK products have environmental benefits in use and the company takes great care to ensure that its choice and use of raw materials, manufacturing processes, packaging and transport are all carried out to the highest environmental standards.
At H+H UK we categorise the different elements of the sustainability agenda in three key areas:
- The product in application
- The manufacturing process
- Our company ethics
The Benefits of Aircrete
Aircrete is the generic term for cellular concrete. The millions of tiny air bubbles trapped within a Celcon Block provide a wide range of benefits:
Excellent thermal insulation reduces energy use within a building. When combined with other building materials such as brick and insulation products, extremely low U-Values can be achieved, easily meeting the requirements of the energy aspects of the UK's Building Regulations (such as Part L in England). Using simple construction details, the BRE has shown that the use of aircrete can significantly reduce heat loss at thermal bridges within a building (such as at junctions of walls and floors). Being of a relatively high mass (compared to lightweight framed structures), walls built with aircrete can provide a high degree of thermal mass which helps create a comfortable internal environment in the building.
A high strength to weight ratio ensures that H+H aircrete can meet the requirements of the structural design of a building without the manual handling risks associated with heavy masonry materials. The lighter weight of aircrete also means that the loading on a framed structure will be less, thereby reducing the strength requirement of the superstructure or foundations in certain conditions.
H+H has also focused close attention on the energy efficiency of our production processes. We were the first aircrete manufacturer to be awarded the Carbon Trust Standard, and the first company to be awarded a ‘very good’ rating in BES 6001:2008 Standard for the Responsible Sourcing of Construction Products.
In June 2019 the BES 6001 rating was upgraded to Excellent - a very proud moment for everyone at H+H, especially those who worked on the upgrade of the Borough Green Factory and Pollington I & Pollington 2.
When designing our newest plant (Pollington 2) environmental considerations were applied to every aspect. This included the installation of a combined heat and power plant and an advanced rainwater management system.
All water used at the site comes from either a local canal or a lagoon that collects rainwater from the whole site. At H+H’s other factories, waste water from the manufacturing process is also recycled, significantly reducing the quantity of water that needs to be drawn from mains supplies.
Just as significant as our own manufacturing is the role our products play in the construction of sustainable buildings.
Our philosophy is very much one of “fabric first” – that energy efficiency should be built into the fabric of a house so that it remains effective for the lifetime of the building. We believe that this is a far better option than relying on technologies that are either unproven over the longer term or rely on the behaviour of the building occupants for their effect.
Long Life Expectancy
With a very long life expectancy (well in excess of the Green Guide to Housing Specifications 60 year building life),aircrete is a durable material that does not give off any harmful substances or require preservatives to maintain performance.
It does not rot or burn. It is resistant to sulfates and the effects of freeze/thaw cycles and it cannot be attacked by pests such as termites or vermin.
Aircrete's environmental credentials extend to its eventual recycling at the end of a building's life. As well as being an inert material that will far outlast the usual 60 year design life expectancy of a building, aircrete is easily recyclable, and can be crushed down with other masonry materials and used in future applications.
H+H UK will comply with the spirit as well as the letter of environmental legislation and approved codes of practice and will co-operate fully and maintain open relationships with all regulatory authorities.We will assess the environmental effects of our products, projects, policies and operations with a view to reducing and controlling environmental impact. We will also maintain an Environmental Management System (IMS) throughout our production processes and sites, in conformance to ISO 14001.
The System addresses the use of energy, raw materials, air, water and waste and seeks to prevent pollution and limit the environmental impact of the company's business activities. H+H UK will develop contingency procedures to deal with environmental accidents and emergency situations.
It will evaluate, control and reduce, wherever reasonably practicable, noise generated within its various sites as well as the escape of noise to the immediate environment. Seeking to continually improve environmental performance, where it is reasonably practical and economic to do so is a main aim for the company.
H+H UK will foster an understanding of environmental issues arising from our business activities amongst employees, suppliers, contractors, customers, shareholders and also within the local community. We will report publicly on our environmental objectives and performance as and when required.
Environmental Improvement Teams at each site will be responsible for formulating and implementing a programme of objectives and targets consistent with the H+H UK environmental policy. The teams will make regular reports to our Board, who will review the policy on an annual basis, in the light of management reviews of the Environmental Management System.
Pallet Reclamation with Scott Pallets
H+H UK Ltd has an existing relationship with Scott Group Plc, which provides a service to our customers and reinforces our commitment to sustainability within construction. This unique initiative continues to work well, with used pallets being collected from many major house-builders and builders’ merchants.
This initiative is offered completely free of charge to H+H customers and the very unique way in which Scott manages their business ensures that customers are provided with the easiest and most effective methods for collection. Even though our part in the service is designed to help H+H reclaim pallets from our customers, the operation run by Scott works with all companies that provide product on pallets. Therefore, not only H+H pallets are collected from site at any one time.
Provided the site or yard has a minimum of 50 pallets ready for collection, whether whole or damaged, Scott will collect them. The pallets are then returned to the Scott depots where they are sorted, damaged pallets which can be mended, whole pallets which can be recycled. Pallets which are beyond re-use, but could be used for "spare parts".
Having determined the condition of the pallet, they are sorted by company (e.g., H+H pallets) and returned to our depot for re-use. Pallets originally provided by other suppliers and who are members of the scheme are similarly reclaimed and returned to the depots of each company, allowing the re-use of pallets for many companies.

A unique partnership created to pioneer homes for the future.
Building regulations set the bar for energy efficiency, setting out minimum standards for the performance of new homes. However, these are minimum standards and can easily be exceeded.
For those looking for higher performance standards, the Code for Sustainable Homes provides useful additional insight. Although not mandatory and, indeed, no longer part of the Government’s plan for improving the quality of new build, the Code is still widely recognised as a measure of both energy efficiency and sustainable development.
The Code included several levels of performance: Code Level 3 is essentially equitable to current Building Regulations. Code 6 is essentially zero carbon. Any performance above Code Level 3 is a very energy efficient home.
One of the reasons that the Code was abandoned by Government was the perceived cost and complexity of building to the higher levels of the Code. At H+H we wanted to prove that it was possible to achieve Code Level 4 without relying on renewable energy sources (such as Solar PV or heat pumps) and were therefore delighted to participate in in the AIMC4 project which set out to prove just that.
The consortium provided a unique collaboration between developers Stewart Milne Group, Crest Nicholson Plc and Baratt Developments Plc together with H+H UK Ltd and the Building Research Establishment.
Using funding from the Technology Strategy Board, the consortium constructed twelve world-class energy efficient innovative homes that achieved Level 4 through the design of the building fabric and primary building services alone. A range of construction methods was included in the study, including H+H’s Thin-Joint system.
H+H’s contribution to the project was based on out technical knowledge, both of our own products and the construction industry as a whole.
