Our Accreditations

At the start of April 2002, all installations of windows and doors in Double properties had to be registered directly with Local Area Building Control (LABC) or with a government licensed competent person (CP) Scheme. There are currently five such schemes available within the industry, and Advanced Doors and Windows is registered with one of the largest; Certass. Licensed in April 2006, Certass is now the second largest competent person scheme in the country, and requires its members to supply their customers with a written guarantee and contractual documentation once an installation is complete. This is by way of proving that our installations are competently and professionally fitted, displaying our knowledge of the most up to date building regulations.

Throughout the year, audits and inspections are conducted to ensure that consumers receive consistently first class work. After our installations have been completed, we notify Certass who will send the certificate directly, or to a specified correspondence address, and this should take less than 30 days to arrive. In the summer of 2014, the government launched a new initiative to help the consumer choose a contractor that was seen to be competent at both surveying and installing. Part of being in Certass ensures we have to go through this process which has been called a Minimum Technical Competency (MTC) and once in place we will have a photo ID card to prove we have this requirement.

As part of being in Certass, we have to be in a position to supply an insurance backed guarantee (IBG) as standard on all our installations of windows and doors. For this we use Quality Assured National Warranties (QANW). QANW were founded over 20 years ago and are the UK's leading supplier of IBGs, covering many different types of domestic and commercial projects. They only buy UK based insurance and in the unlikely event of the company ceasing to trade, the consumer will still have their installation guaranteed should any defect occur during the guarantee period.
