What is Quiet Mark certified products?

Noise is an important factor to consider when specifying a property. Tenants and homeowners prefer quieter neighbourhoods, quiet neighbours, and above all, quiet heating at home. Quiet Mark technically assesses and certifies

the quietest solutions to unwanted noise. A Quiet Mark certification differentiates the quietest products in the market including home heating and appliances, building sector materials, and commercial sector products. 

Four fifths of UK consumers say it matters how loud an appliance is when buying a product. Excessive noise can increase stress levels, disturb sleep, and reduce productivity. By choosing Quiet Mark certified products from Worcester Bosch, you can help homeowners and tenants enjoy life at home without disturbance.
