Sustainability…the Ibstock Way

Sustainability is at the core of our strategy. As the UK’s leading brickmaker we are very aware of the impact our operations and products can have on the environment and communities in which we operate. Our aims are to:

  • Continue to work with local communities.
  • Achieve zero workplace accidents.
  • Increase the amount of recovered water we use.
  • Use our resources in the most efficient manner possible to reduce waste.
  • Reduce the amount of energy we use by improved process control.
  • Continue to investigate alternative sustainable forms of energy.

Social progress

  • Our manufacturing network enables more products to be delivered locally.
  • We provide high levels of skill and stable employment within communities.
  • We support local, often rural, communities and are the biggest employer in some areas.
  • We support local contractors and source local materials where possible.
  • We have an active corporate social responsibility programme including social welfare programmes.
  • We sponsor many local clubs and societies.
Ibstock are continuing to investigate alternative sustainable forms of energy

Economic growth

  • We financially support community projects through the Ibstock Cory Environmental Trust under the Landfill Tax Credit Scheme.
  • We maintain our established policy of investment in high efficiency/low carbon technologies.
  • Chesterton, the new Ibstock factory and one of the largest investments in the Potteries ceramics industry for over a decade, is setting world-beating standards for sustainability and energy efficiency.
  • We have and continue to heavily invest in energy efficient projects.
  • We publish an annual environmental report available on our website.
  • We partner several university research projects including the development of alternative energy sources.

The Environment

  • All our manufacturing units source their materials responsibly and are certified to BES 6001.
  • All our manufacturing units are independently verified and registered to ISO 14001, the International Environmental Management Standard and ISO 9001, the International Quality Management Standard.
  • Our bricks, on average, travel only 82 miles reducing traffic congestion, vehicle emissions and fuel usage.
  • We undertake pro-active research in environmental technology which has included fluorine reduction at our Leicester factory.
  • We have on-going continuous improvement programmes at all our factories with benchmarking of key performance improvement indicators.
  • We are the first brickmaker to achieve ISO 50001, the new Energy Management Standard.

Natural Resources

  • We operate some of the most energy efficient factories in Europe with proven energy reduction year-on-year.
  • On average our products contain 10% re-cycled secondary or waste material, extending the use of valuable clay resources.
  • Water, a key commodity in brickmaking, is recovered and re-cycled wherever possible. Over 40% of all water used is recovered water.
  • All process waste up to the kiln-firing stage is re-cycled.
  • 13.6MW of electricity is generated from Landfill gas on our sites, enough to power 17,000 homes.
  • Raw materials are sourced responsibly, with full restoration of our clay extraction sites, which are often used for the creation of local amenities.

BREEAM, BRE Green Guide and BES 6001

BREEAM is an environmental assessment method by which new buildings are assessed against set criteria providing an overall score. Materials for these assessments are sourced through information obtained from BRE’s “Green Guide”. External wall specifications, when assessed in conjunction with this guide, are given a points rating from “A+” to “E”. All brick cladding specifications listed in the Green Guide achieve the highest (A+) rating.

Being certified under BES 6001 demonstrates compliance with a recognised responsible sourcing scheme which is certified through a third party and which is supported by UKCG members and who give preference to procuring products demonstrating such compliance.

Eco Habitats…for Bats

In the UK there are 17 species of bats, all of which are protected by law. Our range of bat boxes helps to encourage safe habitats for these remarkable mammals, allowing them to live in harmony with people.

Eco Habitats for swifts

Swift Box

Swifts come to the UK for just months each summer from Central and Southern Africa. Despite legal protection their numbers are declining. Since Roman times they have been at home in traditional man-made buildings. However they find it increasingly difficult to find nest sites in modern or refurbished buildings due to the effective sealing of the eaves.

  • Designed with the needs of the swift in mind
  • Available in Smooth Blue, Smooth Cream and Smooth Red
  • Discrete nesting box for location near eaves
  • Ideal for new build and conservation work

Coolvault®…add thermal mass where it matters

For attractive ceilings with an environmental benefit

Natural clay has great thermal mass properties. It absorbs excess heat in hot conditions and releases it gradually as temperatures fall, helping to maintain a comfortable internal temperature.

  • Manufactured in the UK using over 90% recycled clay.
  • Adds thermal mass to even lightweight construction.
  • Suited for use with underfloor heating systems.
  • Can help reduce the amount of conventional heating or cooling that a building may require.
  • Available in natural cream or terracotta; the naturally C reflective surface requires no decoration.

Ecoterre® Earth Bricks…for internal non load bearing applications

A range of unfired clay bricks suitable for most internal non load-bearing applications. Unfired brickwork can be finished with a variety of materials including clay and lime plasters, clay boards, some paints and limewashes, making it an attractive addition to any building.

  • When incorporated into a building, it will help provide thermal mass and acoustic insulation, inhibit condensation and regulate the relative humidity of the atmosphere.
  • Excellent sustainability credentials including; low energy input, very low waste and high recyclability.
  • Available in two sizes with the option of a smooth finish.
  • Excellent bond properties with appropriate plaster or mortar.
  • Long life – potentially centuries if the correct care is given.
  • Allows customers to improve the energy efficiency of their home.

Handling & Storage

Only forks should be used to unload the pallets and the movement of unfired clay bricks should be kept to a minimum. Store in the dry on the original pallet and ventilate to avoid condensation. They should be stacked no more than two packs high.


It is recommended that moderately hydraulic lime mortar should be used to lay the bricks. Alternatively clay mortars are available.


Unfired clay brickwork can be finished with a variety of breathable materials including clay and lime plasters, clay boards, some paints and limewashes. Only highly vapour permeable paints should be used.


Unfired clay bricks will generally only require standard fixings for secondary works, such as plumbing, electrics and joinery. Ordinary masonry plugs and screws are suitable for most applications – a list of approved products is available below:
