Find the right 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.

What to Expect When Hiring a Conservatory Specialist

Hiring a conservatory professional involves a structured process to ensure the new structure integrates seamlessly with your existing property. Here is the typical workflow:

• Initial Consultation & Design: The installer will visit your home to measure the site, discuss styles (Lean-to, P-shape, Gable-end), and determine if you require a dwarf wall or full-height glazing.
• Planning & Regulations: They will advise if the project falls under "Permitted Development" or if a full planning application and Building Regulations approval are required.
• Groundworks and Base: This stage involves excavating foundations, laying a concrete slab, and constructing any necessary masonry walls to support the frames.
• Frame & Glazing Installation: The uPVC, aluminium, or timber frames are erected, followed by the installation of high-specification double or triple glazing.
• Roofing: The specialist installs the roof system, which could range from polycarbonate and toughened glass to lightweight composite tiles.
• Internal Finishing: This includes installing flooring, electrics (lighting and sockets), heating (radiators or underfloor), and plastering any internal walls.

Why Hire a Professional?

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.

Typical Costs

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.

How to Choose the Right Conservatory Specialist

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:

• Check Accreditations: Ensure they are registered with FENSA, CERTASS, or the GGF (Glass and Glazing Federation).
• Insurance-Backed Guarantees: Always ask if their 10-year guarantee is insurance-backed, which protects you if the company ceases trading.
• Review Previous Work: A reputable specialist should be able to show you a portfolio of local installs or even arrange a visit to a past customer's home.
• Get Detailed Quotes: Ensure the quote breaks down groundworks, frames, roofing, and internal finishes so you aren't hit with "hidden extras."

Questions to ask before hiring:

• "Will you handle the Building Regulations application on my behalf?"
• "What is the U-value of the glass you are proposing?"
• "Does the quote include electrical work and flooring, or is it for the shell only?"
• "How long will the site be open to the elements during the build?"

Frequently Asked Questions

Do I need planning permission for a conservatory?

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.

Can I use my conservatory all year round?

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.

How long does it take to build a conservatory?

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.

Is a tiled roof better than a glass roof?

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.
