Conservatory & Orangery Cost Guide for 2026

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 2026.

How much does a conservatory cost in 2026?

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:

Conservatory Style	Low Range (£)	High Range (£)
Lean-to	£9,000	£14,250+
Victorian	£12,000	£17,500+
Edwardian	£10,500	£18,000+
Orangery / Complex (P-shape, etc.)	£15,000	£30,000+
Bespoke Builds	£30,000	£40,000+

 

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

Example guide prices by popular sizes (installed-style guidance)

Some of the most popular styles (using Ultraframe conservatory roofing systems) have historically been guided at:

• Georgian Style – 4000mm x 4000mm: £10,500 – £20,000
• Lean-to Style – 3000mm x 3000mm: £8,500 – £15,000

These are guide prices and should be treated as indicative—your final price will depend on specification, site conditions, and finishing choices.

Is it cheaper to have a home 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 conservatory in 2026 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 (or orangery) 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 2026 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. With Ultraframe’s innovative roofing systems, energy-efficient glazing, and customisable designs, your new conservatory can be more than just an extension—it can be your favourite room in the house.

Practicalities to weigh up before you budget

 

When you’re considering having a conservatory (or orangery) built, it helps to weigh up:

• Price: What will it cost, how will you pay, and what additional costs might be involved (building work, cosmetic finishes, changes to the adjoining area)?
• Practicalities: How much planning is required, will you need to rearrange how you live during works, and will planning permission be required?
• Timescales: When do you want it completed, and how might weather/time of year affect the build?

By choosing a member of the Ultra Installer Scheme, these topics should be covered in one-to-one discussions and within a full proposal (costings, drawings, and timescales), so you know exactly what’s involved.

What are conservatory and orangery prices based on?

Below are the main variables that impact cost—whether you’re choosing a conservatory or an orangery.

1) Size

Bigger structures require more materials and usually more labour. Your property layout, build location, and the space you need should guide the size you choose.

2) Design

Conservatory or orangery, contemporary or traditional—design choices affect both the look and the price. Your nearest Approved Ultra Installer can help you choose the best option for your home and space.

3) Materials (frames, doors, finish)

From frames to roof systems, there are major cost differences:

• uPVC is generally less expensive than timber or aluminium. It can replicate the look of timber and won’t warp or rot like wood over time.
• Aluminium is strong and slim (great for larger spans of bi-fold or sliding doors and uninterrupted sightlines).
• Both uPVC and aluminium offer broad colour choice and low ongoing maintenance.

4) Walls

You can choose fully glazed, dwarf, or full-height walls. Full-height glazing is increasingly popular for contemporary looks (especially alongside modern bi-fold or sliding doors), but your property and location may influence what’s possible.

5) Roof (and roof lanterns)

Whether you choose a glass roof, solid roof, or a mix of both, the roof type and thermal performance can drastically affect costs and comfort.

Roof lanterns / roof lights add light and architectural impact but will influence overall pricing depending on size, glazing choice, and positioning.

6) Extras

Once the basic structure is agreed, optional upgrades can shape the final budget, including:

• Internal lighting systems
• Internal pelmets
• Ventilation
• External cornice (to hide guttering)
• Decorative, insulating columns

Orangery cost: what can push the price up (or help control it)

If you’ve decided on an orangery extension, you’ll want to think carefully about the design of your new room. The materials you choose and the company you instruct to complete the installation will influence the overall cost.

Traditional orangery vs contemporary orangery

A more traditional orangery uses more masonry than glazing, so costs can rise if you opt for a heavy brick design. There are alternatives to brick you can discuss with your installer to reduce cost while still achieving the look you want.

Brick piers vs super insulated columns

Our contemporary and classic orangeries can feature either of these. Both are stylistically outstanding, but there are key performance differences:

• Super insulated columns can deliver thermal performance up to five times higher than a brick pier of the same size.
• These options are very similarly priced, but super insulated columns are faster to install, which can help reduce installation costs.

Standard glass vs performance glass

Performance glass can make a big difference to comfort. Options may include solar glare reduction, thermal efficiency, UV protection, self-cleaning, noise reduction, and more.

Performance glass can increase the cost, but it’s often worth it—particularly if your orangery is in a very sunny or shady spot where comfort is harder to control.

What’s included in “guide prices” (typical assumptions)

Guide prices are usually based on general specifications and “ideal” circumstances. For example:

• Level ground, easy to dig
• No drainage/soil stacks to move
• Gutters connect into the existing house system
• ~450mm deep foundations on concrete strip/insulated base
• ~600mm fair-faced masonry to external/internal walls
• White uPVC frames (reinforced if needed), with 4 top light openers and one pair of doors with white handles
• Multi-point locking on windows/doors
• Toughened 24mm or 28mm sealed units in clear glass to side glazing
• White pre-finished internal window boards
• Ultraframe conservatory roof with polycarbonate glazing
• Float finish to floor slab (ready for carpet/tiles)
• 2 double power sockets

Your quote may vary depending on individual circumstances, including the time of year and where you live.

Choosing the right installer (and why it matters)

Selecting a trusted installer is vital. Will they be using authentic Ultraframe products? Do they have the experience and knowledge to get the installation right first time? If not, it could cost you time and money later.

Time is money. The longer your installer spends on-site, the higher the cost of your project. Ultraframe products are pre-fabricated at a dedicated factory, which can reduce installation time—less intrusion, less messy cutting on-site, and a faster route to completion.

Best practice: get 3 installers to visit, discuss your exact requirements, and quote. That gives you a clear comparison of price, scope, and timescales.
