PLK Home & Window Maintenance are a CERTASS Certified Installer.

All Certass Certification Scheme member contractors are regularly audited on-site and at the contractor premises.

The contractor’s paperwork is also checked to ensure that his business procedures meet the requirements of Government endorsed standards. Certass members have direct access to a range of industry experts for immediate clarification and technical advice on building regulations via a technical helpline as well as online access to a technical manual which is updated at regular intervals.

Certass Certification Scheme membership requires that a contractor must be able to provide customers with:

  • A guarantee covering the completed installation
  • Financial protection with an Independent Backed Guarantee (IBG) to cover the Building Regulations requirements for 6 years should they cease trading
  • Suitably qualified and assessed site operatives

Certass carries out random audits on a percentage of a contractor’s work to ensure the work has been carried out in accordance with required standards.

We are also members of the Certass Trade Association. This is not a certification scheme; it is a Trade Body representing the interests of industry and offering membership benefits to members. Certass Trade Association membership is displayed in the public search.
