Types of Conservatories and Their Costs

Conservatories come in a range of types and sizes, all of which influence the final construction cost. Below are the most popular types of conservatories and their estimated costs, based on a typical 4 x 3 metre size.

1. Glass-Roof Conservatory

A glass-roof conservatory offers a clear view of the sky, ideal for those who enjoy natural light or stargazing. This style tends to be on the higher end of the price range due to its fully glazed roof.

2. Tiled Roof Conservatory

A tiled roof conservatory provides better insulation, making it a solid choice for year-round use, particularly in colder regions. The added insulation can help with heating costs, but it comes with a higher initial price tag.

3. Orangery

An orangery combines the brightness of a glass structure with the solidity of a brick design, creating a more integrated extension to your home. Orangeries are generally the most expensive option but are known for their durability and traditional aesthetic.

What Determines the Price of a Conservatory?

Several factors affect the cost of a conservatory, from materials to location. Here’s a breakdown of what you might expect to pay for each type.

Glass-Roof Conservatory Costs

A standard 12 square metre glass-roof conservatory typically costs between £32,000 and £42,000, averaging around £3,000 per square metre, depending on your location and specifications.

Tiled Roof Conservatory Costs

This sturdier option generally costs between £19,000 and £26,000, or roughly £1,800 per square metre. Tiled roofs offer enhanced insulation, which can be beneficial in colder areas.

Orangery Costs

Orangeries blend substantial building materials with large windows, typically ranging from £34,000 to £47,000, or approximately £3,300 per square metre. They are known for their longevity and seamless integration with traditional house structures.

Breaking Down Conservatory Costs by Construction Stage

To give you an idea of where your money goes, here’s a cost breakdown based on a glass-roof conservatory project in London:

• Roof and Structural Work: About 45% of the total cost, covering materials and installation.
• Windows and Doors: Approximately 25%, impacting both appearance and insulation.
• Foundations: Around 9%, essential for long-term stability and durability.

Additional Costs and Considerations

Remember that these estimates typically exclude VAT, as well as additional costs for optional features like heating, bespoke designs, or unexpected groundwork. Additionally, planning permission might be required depending on your local council’s regulations, so be sure to factor in any fees related to permits or inspections.

Frequently Asked Questions

Can conservatories be used year-round?

Yes, conservatories can be enjoyed year-round with the right insulation, heating, and cooling solutions. Key features like a tiled or solid roof help regulate temperatures, keeping the conservatory warm in winter and cooler in summer. Double or triple-glazed energy-efficient windows prevent heat loss in cold weather and reduce solar gain in warmer months. You may also consider options like underfloor heating or electric radiators, which are effective and affordable ways to create a comfortable year-round space.

Is it cheaper to build a conservatory or an extension?

Generally, conservatories are more cost-effective than full extensions due to simpler structures and fewer materials. A standard conservatory typically ranges between £9,000 to £20,000, while extensions often start at £25,000 and can go much higher depending on specifications. However, the cost can overlap if the conservatory includes high-end customisations or advanced insulation. Extensions, being fully integrated with your home, tend to add more usable space and may offer a greater return on investment, but conservatories are an excellent alternative for those looking to increase space and light without a major expense.

How long does it take to build a conservatory?

On average, building a conservatory takes between three to six weeks. The timeline can vary based on factors like the complexity of the design, site conditions, weather, and whether the conservatory requires additional groundwork. For simpler builds, such as a small lean-to conservatory, the process may be completed in as little as two to three weeks. More complex or custom designs may take closer to six weeks or longer, especially if unexpected delays arise. Planning ahead and choosing experienced professionals can help keep your project on schedule.

Do conservatories add value to a property?

Yes, conservatories can boost your property’s value by up to 7%, according to property experts. Buyers are often drawn to the added space and light that conservatories provide, making them an attractive feature when selling. While value-added can depend on factors like location, quality of construction, and how well the conservatory integrates with the existing property, it remains a popular way to enhance appeal without a full extension. For maximum impact, consider design elements that complement the style and size of your home.

Is there a best time of year to build a conservatory?

Spring and summer are generally the best times to build a conservatory. Warmer, drier weather reduces the chances of weather-related delays, allowing contractors to work efficiently. This can mean a faster turnaround and fewer interruptions. That said, autumn can also be a good choice if you want to avoid peak construction periods, as many builders may have greater availability. Winter is usually the least ideal time due to potential weather issues, which can delay projects, though you may be able to find competitive rates during this period.

What maintenance does a conservatory require?

Conservatories are relatively low-maintenance, but they do benefit from regular upkeep. Routine cleaning of windows and roof panels helps maintain clarity and prevents algae or debris buildup. Check for any signs of wear and tear, such as leaks or condensation, particularly after winter. Cleaning gutters regularly is important to prevent blockages and avoid water damage. If your conservatory has a uPVC frame, wiping it down with a mild cleaner helps preserve its appearance, while wood frames may require occasional repainting or sealing to protect against weather damage.

Do I need an architect for a conservatory?

Hiring an architect for a conservatory isn’t usually necessary unless you have specific design requirements. However, for bespoke designs or complex builds, consulting an architect can ensure the structure integrates well with your home and complies with building regulations.
