Four moves that separate a smooth job from a nightmare.
Polycarbonate (cold) = cheapest but freezes/bakes. Tiled (warm/solid) = year-round usable but needs Building Regs. Solid roof retrofits are a common upgrade.
Solid-roof conservatories are habitable extensions under Part L. The retrofit specialist must handle Building Control — confirm before signing.
A conservatory needs proper concrete foundations under any dwarf walls — same depth as house foundations. Slab-on-grade only is a future settlement crack.

Conservatories explained
Everything you need to know before hiring a conservatories.
A conservatory specialist is a skilled professional who designs, builds, and maintains glass-walled extensions. These tradespeople combine elements of bricklaying, glazing, and roofing to create bright, versatile spaces that add significant value and square footage to UK homes.
Modern conservatory services have evolved far beyond the basic "white uPVC" structures of the past. Today’s experts handle everything from traditional Victorian and Edwardian styles to contemporary orangeries and high-performance tiled roof replacements that ensure the room remains comfortable year-round.
Whether you are looking to build a new sunroom from scratch, repair a leaking roof, or upgrade your existing structure with energy-efficient glass, a conservatory specialist provides the technical expertise to ensure the build is structurally sound and thermally efficient.
Hiring a conservatory professional involves a structured process to ensure the new structure integrates seamlessly with your existing property. Here is the typical workflow:
While some small repair tasks might seem like DIY projects, building or upgrading a conservatory requires professional expertise to meet UK Building Regulations. A professional ensures the structure can handle "snow loads" and wind pressure, preventing catastrophic failure during extreme weather.
Thermal efficiency is another critical factor. Under Part L of the Building Regulations, new extensions must meet strict insulation standards. A professional installer will use Low-E glass and thermally broken frames to prevent the "greenhouse effect" in summer and heat loss in winter.
Furthermore, hiring a member of a competent person scheme like FENSA or CERTASS is vital. These installers can self-certify their work, providing you with the necessary certification required when you eventually come to sell your home.
The cost of a conservatory varies significantly based on the materials used, the complexity of the groundworks, and the type of roofing system selected. Below are estimated costs for 2025/26 including VAT.
| Service | Low £ | High £ | Notes |
|---|---|---|---|
| Small uPVC Lean-to | £10,000 | £15,000 | Basic design, polycarbonate roof. |
| Victorian/Edwardian (3m x 3m) | £15,000 | £25,000 | uPVC with glass roof and dwarf wall. |
| Tiled Roof Replacement | £6,000 | £12,000 | Retrofitting a solid roof to existing frames. |
| Modern Orangery | £30,000 | £60,000+ | Substantial brickwork and lantern roof. |
| General Repairs/Leak Fixing | £300 | £1,500 | Replacing seals, panels, or guttering. |
Price fluctuations are often driven by the choice of frame material (aluminium is typically 30-50% more expensive than uPVC) and the necessity for extensive drainage or utility rerouting during the groundworks phase.
Choosing the right installer is the difference between a room you use every day and a "white elephant" that is too hot or too cold. Follow these steps to find a reputable pro:
Questions to ask before hiring:
In most cases, conservatories are considered "Permitted Development" and do not require planning permission, provided they meet specific size limits and height restrictions. However, if you live in a Conservation Area or a Listed Building, or if the extension exceeds 50% of the land around the original house, you will likely need formal approval.
Older conservatories often struggle with temperature regulation, but modern builds with solar-control glass or solid tiled roofs are designed for 365-day use. Adding integrated heating, such as electric underfloor heating or vertical radiators, is highly recommended for the winter months.
A standard uPVC conservatory usually takes between 3 to 5 weeks to complete. This includes roughly one week for groundworks and foundations, one week for the frames and roof, and a final week for internal finishing and flooring. Complex orangeries or those requiring significant brickwork may take 8 weeks or longer.
Tiled roofs offer superior thermal insulation, making the room feel more like a traditional house extension. Glass roofs, however, provide maximum natural light. Many homeowners now opt for "hybrid" roofs which feature large glass panels inset into a solid, insulated tiled structure.
