About Lime Green
Founded in 2002, Lime Green is the UK's leading manufacturer of lime mortar, lime plaster, and lime render. We’ve also expanded our expertise by introducing specialist non-lime products and pioneering the use of natural wood fibre insulation.
Our relentless commitment to excellence is fuelled by continuous collaboration with others working in the sector, ongoing research, and innovation in areas like product chemistry, environmental sustainability, and historic building preservation. As well as the many certifications our products hold, the business is also ISO 9001 certified.
This dedication and constant ethos of improvement ensures that our products consistently perform to the highest standards, are user-friendly, and guarantee the longevity and integrity of the buildings they are used on.
This is why our materials are trusted on Britain’s most iconic and historic landmarks, innovative ecological developments, and a vast array of smaller projects, renovations and self-build ventures.
State-of-the-Art Plant in Shropshire
Building on over 500 years of lime production heritage at Wenlock Edge, Lime Green has expanded and now has sites just outside Much Wenlock. A state-of-the-art mixing plant and a new office, training, and warehouse complex.
Our plant, which opened in 2018, received a substantial investment in 2023, with the introduction of a new mixer, a new automated packaging line was also added in early 2024, featuring an automatic bag filler, conveyor, and robot that efficiently lifts and shrink-wraps pallets. The result, the ability to triple production, reducing lead times and free up staff to work in other areas of the business.
Lime Green now has suffcient capacity to meet the increasing demand for lime based products .
In 2024, we further expanded by acquiring a second site nearby, increasing our office and warehousing space while also adding new training and demonstration areas.
Quality Assured Lime Products
Our lime products are meticulously crafted based on historic recipes, combining precise formulation with rigorous quality assurance.
This guarantees peace of mind when using our lime mortars, renders, and plasters.
Co-founder and Operations Director James Ayres explains...
“Our plant is engineered for extreme precision, with some ingredients measured as accurately as 1 gram per tonne. This allows us to produce products with consistent quality over time while optimizing raw material and energy use. The bulk storage system is cleaner and safer, with materials stored in sealed, monitored silos. This has also significantly reduced HGV traffic and minimized packaging waste on-site.
Our plant's versatility allows us to seamlessly switch between products, from traditional Roman cement and limes to modern low-carbon binders. This flexibility is crucial in meeting the short lead times that many contractors face.”
