Conservatory Cost Guide for 2025

Without a personalised quote, it’s hard to say exactly how much a conservatory extension will cost for your home. This is due to varying factors such as the size and specifications of your new conservatory design, and even where you are in the UK due to regional differences in building costs.

We have put together a guide to help you understand a rough cost of your conservatory in 2025.

How much does a conservatory cost?

The average conservatory price in the UK starts from £15,000 for materials, excluding labour costs. The style and size of your new conservatory is the biggest factor influencing the overall price.

Below is a breakdown of typical price ranges by style:

Please note: These figures are a rough guide for materials only and do not include labour, groundwork, or finishing costs.

Is it cheaper to have an extension or a conservatory?

In most cases, a conservatory is more affordable than a traditional home extension. The average extension in the UK costs between £1,800–£3,500 per m², compared to £1,300–£1,500 per m² for a conservatory.

However, going for the cheapest option such as a basic uPVC frame with polycarbonate roofing can mean compromising on insulation, longevity, and overall comfort. Higher quality materials, like Ultraframe’s advanced glass roofs or solid roof systems, may cost more initially but will pay off in performance and lifespan, giving it an extension feel for all-round use.

How much is a new conservatory roof?

Replacing your conservatory roof can cost between £4,000 and £15,000, depending on the size, style, and material:

• Polycarbonate replacement: From around £4,000 (budget-friendly, but less energy efficient)
• Glass replacement: £6,000–£12,000 (better light, insulation, and durability)
• Solid / tiled roof conversion: £8,000–£15,000 (excellent thermal efficiency, modern look, year-round use)

Upgrading your roof is often the most effective way to improve comfort, reduce energy bills, and extend the lifespan of your conservatory.

How much does it cost to install a conservatory in the UK?

Labour costs for conservatory installation typically range from £5,000 to £10,000, depending on the complexity of the build, groundworks, and finishing requirements. When budgeting, always factor in:

• Foundations and base work
• Glazing installation
• Roof fitting
• Internal finishes (plastering, electrics, flooring, heating)

A fully installed conservatory in 2025 can therefore range from £15,000 for a basic design to £40,000+ for premium, bespoke builds.

Does a conservatory add value?

Yes, when well-designed and built to a high standard, a conservatory can increase your property’s value by around 5–10%. Buyers often see it as a desirable lifestyle feature, adding flexible living space that can be enjoyed year-round.

The key to adding value is quality. A poorly built conservatory with cheap materials can have the opposite effect, whereas a high-performance structure from Ultraframe enhances both aesthetics and practicality.

Is a new conservatory worth it?

Absolutely, if you choose the right design and materials. A conservatory can:

• Create extra living, dining, or entertaining space
• Bring natural light and a connection to the outdoors
• Offer year-round usability with the right glazing and roofing technology
• Increase your home’s market appeal and potential value

With Ultraframe’s market-leading roofing systems, advanced insulation technology, and stylish design options, your conservatory will be a comfortable, energy-efficient extension of your home for many years to come.

Investing in a conservatory in 2025 can be a smart, cost-effective way to expand your living space and enhance your home’s appeal. While prices vary depending on size, style, and materials, the value lies in choosing a design that complements your property and meets your lifestyle needs.

By opting for quality materials and expert installation, you’ll enjoy a bright, comfortable, and versatile space that performs year-round and stands the test of time.
