Since 1 April 2002 Building Regulations have applied to all replacement glazing, and these apply to security, thermal performance and other areas such as safety, airtightness, means of escape and ventilation.

External windows or doors, such as a new front/entrance, bifold, sliding, French or single door or a tilt and turn windows or rooflights, is a “controlled fitting” under the building regulations and, as a result of this classification, these regulations set out certain standards to be met when such windows or doors are replaced.

When having your new doors and windows installed, you could use an installer registered with a competent person scheme such as CERTASS. All Kloeber installers are registered with CERTASS, this means they are approved to carry out the work to comply with building regulations without needing to involve local authority building control. When work is complete you will also receive a certificate showing the work was done by your Kloeber CERTASS registered installer.

If you’d like to find out more about CERTASS, please refer to our CERTASS Help Sheet on our Customer Support page.

Our installers hold NVQ Level 2 or 3 qualifications, CSCS certificates and are extensively trained and experienced. We are also signed up to the Contractors Health and Safety Assessment Scheme (CHAS) and the SMAS Worksafe Contractor Scheme, meaning we meet the necessary installation health and safety standards. We also have many other accreditations and certifications for health and safety and product quality. You can find the full list at the bottom of our homepage under the “Our values, memberships & awards” section – click on any of the logos to find out more information about them.

If you use unregistered installer or go the DIY route, sign off can be sought from the relevant Building Control Body either at your Local Authority or from an approved inspector. On inspection, they will check the replacement window(s) or door(s) for compliance and, if satisfied, issue you with a certificate of compliance.
