INCA, The Insulated Render and Cladding Association, is THE recognised trade association for the external wall insulation (EWI) market in the UK. Our membership comprises of all the main system designers, a national network of installation contractors and key component suppliers and industry aligned associates.

When you choose an INCA member for your project you are giving yourself the peace of mind that you are dealing with an EWI expert with overarching values of quality, customer service, best practice and business excellence.

Whilst we work closely and collaboratively alongside other associations within the insulation industry – SWIGA, National Insulation Association (NIA), Insulation Assurance Association (IAA) to name but a few, what sets INCA apart is that we are solely focussed on external wall insulation within this wider insulation market. We support all industry sectors – new build, refurbishment, domestic, non-domestic, high rise, low rise, off site, MMC, self-build etc and all size of projects too … any form / size of construction / renovation which involves external wall insulation.

You may find it useful to visit our Case Studies section of the website for examples of work our members have been involved in to date.

INCA Member – The Badge To Trust

So, by choosing an INCA member for your project you know you are dealing with a professional company with specific expertise in the EWI market. Each one has signed up to the INCA code of practice too and so you are giving yourself the assurance of quality and best practice.

But there’s more … not only are INCA members providing you with this assurance but they are active (on a voluntary basis) in supporting the evolution, development, best practice and quality within the external wall insulation industry as a whole. This includes:

Best Practice & Technical Guidance: Via our Technical Committee INCA develop and publish industry best practice and technical guidance documentation for use across the industry. As it is  written and published by the INCA membership it’s the members who set the standards and therefore conform to best practice at all times.

Building Regulations: Again our volunteer member Technical Committee are active in supporting the regulatory bodies in the development and publication of building regulations.

Training: From training manuals, course content and national / regional training initiatives INCA members are actively supporting the development career paths and opportunities for entrants of all ages and levels of experience in the EWI industry.

Industry Development: The INCA volunteer Marketing Committee made up of our membership are actively in the promotion of best practice within the EWI industry to ensure quality is maintained.

Regional Differences: Whilst INCA represent the EWI industry throughout the UK regional variations in relation to regulations and initiatives are recognised through our geographically focussed committees which recognise any specifics in each individual country of the UK.

Funding & Government Initiatives: Our membership work with all relevant Government departments and actively support in the development of funding schemes and other initiatives whilst lobbying to support energy efficiency policy.

As such we work closely alongside a number of key stakeholders – the Department of Energy Security and Net Zero (previously BEIS) the Department for Levelling Up, Housing and Communities, Trustmark, Ofgem, British Energy Efficiency Federation, the Energy Efficiency Infrastructure Group, Solid Wall Insulation Guarantee Agency to name but a few.

Finally, it’s important to note that INCA is a not-for-profit organisation and, as such, our membership have all joined because they want to actively endorse and support our efforts to drive best practice and excellence in all things related to external wall insulation … each one of them is an ambassador for our industry and that’s what sets them apart and why you should always look for the INCA Member badge of quality and assurance.
