Conservatory & Orangery Advice: Your Buying Guide 

Adding a conservatory or orangery to your home is a fantastic way to create more space, increase natural light, and add value to your property. Whether you’re looking for a space to relax, a stylish dining area, or a home office, the right extension can transform your living environment. However, with so many styles, materials, and planning considerations, making the right choice requires careful thought. 

This guide will walk you through everything you need to know about conservatories and orangeries, including key differences, costs, materials, regulations, and common mistakes to avoid. 

1. Conservatory vs Orangery: What’s the Difference? 

Many people use the terms interchangeably, but there are significant differences between a conservatory and an orangery. 

• Conservatories are typically made with a higher percentage of glass, featuring a fully glazed roof and walls to maximise sunlight. They are ideal for those who want a bright, open space that feels connected to the outdoors. 

• Orangeries have a more solid structure, with brick walls, a lantern roof, and large windows. They provide a more permanent feel, offering greater insulation and blending seamlessly with the rest of the house. 

Choosing between the two depends on how you want to use the space, your home’s architectural style, and your budget. 

2. Common Mistakes to Avoid 

Neglecting Insulation and Temperature Control 

Many homeowners love the idea of a sun-filled conservatory but later find it unusable in extreme temperatures. Poor insulation can lead to freezing conditions in winter and unbearable heat in summer. Investing in double glazing, underfloor heating, and high-performance roofing will help regulate the temperature year-round. 

Not Checking Planning Permission Requirements 

Most conservatories and orangeries fall under permitted development rights, but certain conditions apply. If your extension is over a specific size, in a conservation area, or on a listed building, you may need planning permission. Always check with your local authority before starting work. 

Choosing Cheap Materials to Cut Costs 

Going for the cheapest option can be tempting, but low-quality materials can lead to draughts, leaks, and poor energy efficiency. uPVC conservatories, for example, are affordable but may not provide the durability and insulation needed for long-term use. 

Forgetting About Ventilation 

Proper airflow is crucial for maintaining comfort. Without adequate ventilation, condensation and damp issues can develop. Consider adding roof vents, trickle vents, or even bi-folding doors to improve airflow and prevent moisture build-up. 

3. Choosing the Right Style 

Victorian Conservatory 

A traditional and elegant style featuring a multi-faceted bay front, decorative detailing, and a pitched roof. This design is perfect for period homes or those looking for a classic look. 

Edwardian Conservatory 

Similar to the Victorian style but with a rectangular shape, making it more practical for furniture layout. This design suits both modern and traditional homes. 

Lean-To Conservatory 

A minimalist option with a sloping roof, often referred to as a sunroom. It is ideal for smaller homes or where height restrictions apply. 

Gable-End Conservatory 

A striking design with a high, upright roof, creating a dramatic and spacious feel. This is a great choice for homeowners who want a grander, more luxurious extension. 

Orangeries 

A more substantial and integrated extension, featuring brickwork, large windows, and a flat roof with a central glass lantern. This style works particularly well in larger homes and provides excellent insulation for year-round use. 

4. Frame Materials: Pros and Cons 

uPVC 

• Pros: Affordable, low-maintenance, available in multiple colours. 

• Cons: Can look less premium, may not blend well with period homes. 

Aluminium 

• Pros: Modern, slim frames allow for larger glass panes, durable. 

• Cons: More expensive than uPVC, requires thermal breaks for efficiency. 

Timber 

• Pros: Traditional, stylish, excellent insulation. 

• Cons: Requires regular maintenance, higher upfront cost. 

Composite (Wood & Aluminium Mix) 

• Pros: Best of both worlds—durability of aluminium with the warmth of wood. 

• Cons: High price point, but worth it for longevity. 

5. Energy Efficiency & Temperature Control 

A conservatory or orangery should be comfortable to use year-round. To achieve this, consider: 

• Double or Triple Glazing: Prevents heat loss and reduces external noise. 

• Solar-Control Glass: Reflects heat in the summer and retains warmth in the winter. 

• Tiled or Insulated Roofs: An alternative to fully glazed roofs, offering better insulation. 

• Underfloor Heating: A great option to maintain warmth without the need for radiators. 

6. Cost & Budget Considerations 

Prices vary depending on size, materials, and installation. Below is a rough guide: 

Extension Type & Average Cost (Installed): 

UPVC Conservatory: £8,000 – £15,000 
Aluminium Conservatory: £12,000 – £25,000 
Timber Conservatory: £15,000 – £35,000 
Orangery: £20,000 – £50,000 

Additional costs for heating, glazing upgrades, and custom features should also be factored into your budget. 

7. Planning Permission & Building Regulations 

Most conservatories and orangeries fall under permitted development rights, meaning you won’t need planning permission if: 

• The structure does not exceed 50% of your home’s land. 

• It is no taller than 4 metres (or 3 metres within 2 metres of a boundary). 

• It does not extend beyond 6 metres (for semi-detached homes) or 8 metres (for detached homes). 

However, building regulations still apply if you want electrical work, plumbing, or a fully integrated extension. Always consult a professional to ensure compliance. 

Final Thoughts 

A conservatory or orangery is a fantastic way to expand your home, add value, and create a stunning living space. By choosing the right materials, planning for year-round use, and ensuring high-quality installation, you can enjoy a beautiful and functional extension for years to come.
