Conservatory, Orangery & Tiled Roof Extension Costs in 2025 — Full Breakdown

One of the main buying decisions for any homeowner is simple: How do I get the most from my budget

We completely understand. In this industry, it’s no secret that prices can vary wildly. Some quotes are overinflated to cover sales commissions, while others look like a bargain until the work starts. Then quality and service are below your expectations.

That’s why it’s natural to ask: “What should I really expect to pay for a conservatory, orangery or tiled-roof extension in 2025?”

It’s a fair question. And it’s exactly why we created this guide. To give you an honest, up-to-date overview of real project costs, what affects them, and how to make sure your investment delivers genuine long-term value.

Below you’ll find transparent pricing, clear comparisons, and practical examples based on real Precision projects completed across England. 

1. Average 2025 Price Ranges

2. What Affects the Price

1. Size & Shape
   • The bigger the footprint, the more glass, roof sections and foundations are required. Larger Simple rectangular builds cost less than angled or complex footprints.
2. Roof Type
   • Glass roofs are generally cheaper than tiled roofs. Tiled or hybrid roofs provide superior insulation and noise reduction but do cost more.
3. Colours
   • White Frames: lower cost – will match with any existing house windows.
   • Coloured Frames: 10-20% higher.
     • Precision Tip: Most homeowners split the frame going colour out-white in. This reduces the cost of having a colour. The white inside makes it easier to match the inside furniture. 
4. Site Access & Groundworks
   • Restricted access, drainage issues or deeper footings increase labour and material costs.
5. Finishings & Interiors
   • Flooring, plastering, lighting and heating choices can vary a project by several thousand pounds.

3.3 Example 3 – Tiled-Roof Extension (£45-55,000 inc VAT)

• White uPVC frames.
• Includes building regulations, take-down of the old conservatory,  internal house wall removal, plastering and electrics.

4. How to Keep Costs Under Control

1.  Design around how you’ll use the space
   • Start with function, not footprint. A slightly smaller, better-insulated build is often more usable and more cost-effective compared to a larger, colder one.
2. Be realistic about finishes
   •  Interior extras like flooring, lighting and plastering can add 10–20 % to a build. Decide early what’s essential and what can wait. That is how you stay on budget.
3. Combine materials intelligently
   •  Most Precision builds use aluminium for the doors (for strength and slim-frames) and uPVC for the main frame (for insulation and value). It’s a simple way to achieve a premium look without the full aluminium price tag.
4. Choose performance over size
   • A high-spec roof and glass package will do more for comfort and resale value than adding an extra half metre in length. Energy efficiency pays you back long after the build.
5. Fix your price properly
   • Look for a company that offers a fixed-price quote, not an “estimate.” It keeps accountability clear and prevents creeping extras once work starts.

5. What you actually get for your money

Price differences aren’t just about size. They are about specification and finish. Two extensions can look identical on paper but feel completely different once built.

Here is where the money really goes:

Precision Tip: Don’t just compare prices. Compare specification.
A £35,000 conservatory and a £35,000 tiled roof extension deliver very different outcomes in comfort, lifespan, and property value.

6. Which Structure delivers the best value for you?

Each structure has its own strengths. The “best” one depends on how you want to use the space and what look you’re aiming for.

Precision Insight:

If your budget allows, upgrading to an orangery or tiled roof system gives an extra level of insulation and usability all year round.

But don’t overlook a conservatory. With the right roof design, glazing, and heating setup, we can make it a bright, comfortable room that’s functional through every season.

6. Our Honest Summary

It’s easy to get lost in prices, styles, and technical terms — but every successful project comes down to three things:

1. Clarity at the start — fixed quotes, clear drawings, no assumptions.
2. Quality materials, chosen for purpose — not upsold for margin.
3. A company that delivers on its promises.

At Precision, every design is built on those principles.

Whether you choose a conservatory, orangery, or tiled roof extension, our job is to help you invest confidently. We want you to enjoy a finished space that feels like it’s always belonged to your home.
