Introducing the NIA

Welcome to the NIA Consumer website where you will find a large amount of useful information and facts about insulation.

The NIA represents the insulation industry in the United Kingdom; our members include installers and manufacturers who provide a wide range of insulation solutions for your home. The NIA and our members are fully committed to maintaining and raising standards within the insulation industry ensuring that ‘Peace of Mind’ comes at standard for our customers.

The NIA has a Code of Professional Practice that members agree to follow to ensure that the public receive the highest possible level of customer service. The Code covers the following areas:

  • Marketing
  • Customer Contract/Agreement
  • Technical training
  • Assessment and Installation
  • Customer Care/Complaints
  • Guarantees
  • Health & Safety

When our members install Cavity Wall Insulation you will receive an independent 25 year guarantee from the Cavity Insulation Guarantee Agency; for solid wall properties there is a SWIGA (solid wall insulation guarantee) available by request. For all types of insulation our members also work to the highest standards of the British Board of Agrément or equivalent regulatory level.

Insulation can reduce your energy bills and carbon footprint and by using a NIA member you can be satisfied that a professional tradesperson will visit your home and undertake an installation to the highest possible standards.

The sooner you make contact the sooner you can benefit from a warmer home and lower fuel bills. There is also a number of Government grants available to lower the costs, especially for those on benefits and those aged 70 or over, speak to an installer member to find out whether you are applicable today.
