Services
Windows
Our PVCu windows combine low maintenance with high durability, offering superior thermal efficiency compared to traditional wooden frames. Each window features smooth operation mechanisms and concealed gaskets for enhanced insulation. Available in various styles to suit both modern and traditional properties, our windows help reduce energy bills while maintaining aesthetic appeal through multiple design and colour options.
Composite Doors
44mm thick composite doors provide exceptional strength and weather resistance, surpassing standard 28mm PVC alternatives. These doors incorporate advanced security features including multi-point locking systems and shoot-bolt options. Customisable with various finishes, colours, and hardware choices, they offer both enhanced security and aesthetic appeal while maintaining energy efficiency through superior insulation properties.
Conservatories
Custom-designed conservatories transform living spaces with durable PVCu frameworks and energy-efficient glazing. Available in traditional or contemporary styles, our conservatories feature reinforced structures for security and soundproofing. We offer comprehensive design options including decorative glass, colour finishes, and integrated lighting solutions to create functional year-round living spaces that complement existing property architecture.
Conservatory Roofs
The Guardian Warm Roof system provides thermally efficient solid roof solutions for existing conservatories. This lightweight aluminium-framed system achieves 0.15 W/mK U-value with triple-layer insulation, reducing temperature fluctuations and noise pollution. The ventilated design prevents condensation issues while maintaining structural integrity, with installation completed in just three days without requiring major structural modifications.
Bi-Fold Doors
Space-efficient bi-fold doors create seamless transitions between indoor and outdoor spaces with maximum glass panelling for natural light. Available in widths up to 6 metres with multiple panel configurations, these doors incorporate advanced locking systems and thermally efficient double glazing. The low threshold design enhances accessibility while maintaining security and weather resistance for year-round use.

We have just had a Conservatory built by Chelworth Conservatories and are delighted with the extra space we have. It has given us a room which we can relax in and enjoy looking out onto our garden. The bifold doors are great for opening out onto the patio and enjoying the sunshine and warm air to flow through, even when it rains it is a great space to enjoy. The work was carried out to a high standard, the lads were efficent, well mannered and happy to oblige to accommodate small changes. We would be happy to recommend Chelworth Conservatories, for providing a high quality product with very
