Quality Assurance

Day Group has a designated management representative who is responsible for the Group’s Quality Management System (QMS).  The system is based on the requirements of ISO9001:2008.

  • Day Group's quality management system is certified to ISO9001:2008. The assessment and certification is performed by ACS Registrars. ACS Registrars are a UKAS accredited company
  • Day Group's scope of registration includes the production of recycled aggregates and hydraulically bound mixtures, provision of haulage services and primary aggregates. Provision of services to the water treatment industry and our bagged aggregate functions are also within the scope
  • All Company locations are subject to regular internal audits as required by the ISO9001:2008 standard and our quality management system. A sample of Company locations are also externally audited by ACS Registrars on an annual basis
  • Day Group's transport and distribution fleet is inspected and maintained as per VOSA Operators licencing requirements. Vehicles used for the haulage of foodstuffs are externally audited in accordance with TASCC (Trade Assurance Scheme for Combinable Crops)

WRAP/Recycled Aggregates

Producers of recycled aggregates are expected to comply with the Quality Protocol for the Production of Aggregates from Inert Waste, as published by WRAP.

The Quality Protocol has two main purposes:-

  • To assist in identifying the point at which the inert waste used to produce aggregates has been fully recovered, ceases to be a waste and becomes a product.
  • To give adequate assurance that recovered aggregate products conform to standards common to both recovered and primary aggregates.

In order to comply with the WRAP Quality Protocol, producers of recycled aggregates must demonstrate a system of Factory Production Control (FPC) in accordance with BS EN 13242.  Day Group’s QMS incorporates the requirements of FPC and that of ISO9001:2008, ensuring that a robust quality management system is in place.  This gives peace of mind to our customers that recycled aggregates produced at Day Aggregates’ production facilities are fully WRAP compliant.


We ensure that our recycled aggregates are tested against and comply with the relevant European Standard, as well as national specifications (SHW).  All our testing is carried out at independent UKAS accredited laboratories.  These results are available to customers on request.

CE Marking

As of 1st July 2013 under the Construction Products Regulations (CPR) 2011, it became mandatory for manufacturers to draw up a Declaration of Performance (DOP) and apply CE marking to any of their construction products that are covered by a harmonised European standard (HEN).

  • Materials such as Specification for Highway Works Clause 803 Type 1 and Specification for Highway Works 600 series capping and fill materials do not require CE marking.
