Services
Conservatories
We design and install tailor-made uPVC conservatories that offer space and value, combining traditional aesthetics with modern manufacturing techniques. Our Ultraframe roof system ensures superior security and a low-maintenance finish, allowing year-round enjoyment. Each conservatory is customised to complement your home's architecture while enhancing energy efficiency and property value.
Windows
Our double and triple-glazed windows feature thermal insulation, security enhancements, and compliance with Document L regulations. Available in white, woodgrain, or 150 RAL colours, they improve energy efficiency, reduce noise, and increase property value. We ensure A-rated energy performance using high-quality REHAU profiles and secure glazing options.
Doors
Composite doors offer superior thermal efficiency and security, exceeding latest building regulations with PAS 24-certified multi-point locking systems. Available in standard or custom colours, they maintain their appearance with minimal maintenance. GRP skins ensure long-lasting durability and resistance to weathering.
Bi-Fold Doors
ALUK bi-fold doors maximise natural light and connect indoor-outdoor spaces with seamless transitions. Thermal breaks and multi-point locks ensure energy efficiency and security. Available in metallic, wood, or dual-tone finishes, they provide a modern aesthetic while meeting rigorous performance standards for durability.
Tiled Warm Roofs
Our Guardian Warm Roofs replace traditional conservatory roofs with insulated, tiled systems to improve thermal efficiency. This reduces energy costs while maintaining aesthetic appeal. The design mimics traditional extensions, offering year-round comfort and seamless integration with existing property styles through varied colour and shape options.

Platinum have just completed our conservatory and window to double bi fold door conversion. From start to finish this company have been incredible. Nothing is too much trouble and even when I changed my mind a few times it was no big deal. The quality is exceptional. The work rate is exceptional. The staff were courteous and exceptional. Well done lads and keep up the good work! I would have no trouble recommending Platinum. Our new conservatory is testament to anyone wanting to check out their quality!

Report
Extremely happy to recommend Platinum Windows. We had all our wooden framed windows upgraded to UPVC, and a sliding patio door changed to French style. The guys were on time, finished the job to a high spec, were polite and friendly! Also the price was really good value for money. We will use Platinum again should we have any further requirements.
