Complete ICF Construction Packages
ICF Construction Contractors
McGrath Civils Ltd are specialist ICF Construction Contractors, delivering complete Insulated Concrete Formwork (ICF) construction packages for luxury homes, one-off self-builds, basement developments and residential projects throughout London, the Home Counties and the South East.
With more than 30 years of construction experience, we work alongside architects, structural engineers, developers and private clients to deliver complete structural packages, combining expert groundworks, reinforced concrete construction and ICF installation under one experienced contractor.
Whether you're planning a contemporary self-build, an energy-efficient family home or a complex basement development, our experienced team has the expertise to deliver your project safely, efficiently and to the highest standards.
Specialist ICF Construction Contractors
Insulated Concrete Formwork (ICF) has become one of the fastest-growing construction methods for modern residential developments, offering exceptional structural strength, outstanding thermal performance and significantly improved energy efficiency compared to traditional building methods.
At McGrath Civils, we are experienced in delivering complete ICF construction packages using both ICF and Velox insulated concrete formwork systems, providing clients with a faster, stronger and more energy-efficient method of construction.
We are very experienced and in the last 3 years have delivered many ICF related construction projects, across London and the Home Counties.
Unlike many ICF contractors who focus solely on erecting the wall system, McGrath Civils provides the complete structural package. From excavation, foundations and reinforced concrete works through to ICF wall construction, basement structures and ground-bearing slabs, we manage every stage of the build beneath and around the superstructure.
Working closely with architects, structural engineers and developers, we ensure every project is delivered in accordance with engineering drawings, Building Regulations and the highest construction standards.

Why More Homeowners & Developers Are Choosing ICF
The UK housebuilding industry is changing rapidly.
For decades, traditional brick and block construction has been the standard approach. However, rising energy costs, increasingly demanding Building Regulations and a growing focus on sustainable construction are encouraging architects, developers and homeowners to consider more advanced building systems.
Insulated Concrete Formwork (ICF) has emerged as one of the fastest-growing construction methods because it addresses many of the challenges associated with traditional masonry construction.
Rather than simply building a house, ICF creates homes designed to perform better for decades to come.
Today's homeowners expect more from their homes than ever before.
Energy efficiency, lower running costs, quieter living spaces and long-term durability have become just as important as appearance.
ICF construction delivers on all of these expectations, making it an increasingly popular choice for luxury homes, bespoke self-builds and high-quality residential developments throughout the UK.
