Your guarantee as part of your contract of sale will always be with your installation provider. However, it is reassuring to know that the PlatinumNRG range of products comes with a comprehensive set of guarantees from us to our installation partners.

FENSA Compliance

When replacing windows and doors, homeowners must comply with current thermal performance standards and ensure they get a certificate from FENSA (or similar approved) or Local Authority Building Control. FENSA enables companies that install replacement windows and doors to self-certify compliance under these Building Regulations without the need for a separate assessment from Building Control.

CE Compliance

CE marking is the only way to demonstrate that a product, or system, complies with the CPR. It is a manufacturer’s declaration that their product meets the minimum requirements of a harmonised technical specification, enabling them and their agents to place their product on the construction market.

Certificate Number : 002 – date of certification : 30 April 2012. BM Trada scheme for verification of performance characteristics for CE Marking of windows and doorsets in accordance with BS EN 1435101

The Made in Britain scheme was launched by British company Stoves with the backing of UK manufacturers and MPs. To qualify, companies must say ‘the majority’ of their production or manufacturing takes place in the UK.
