Thinking about adding a conservatory to your home?
A conservatory is one of the most popular ways to create extra living space without the cost of a full extension. Whether you want a bright dining room, home office or relaxing garden room, it’s important to understand the costs before you start.
So, how much does a conservatory cost in 2026?
Across the UK, most conservatories cost between £10,000 and £35,000, depending on the size, style, materials and specification. Premium bespoke conservatories can cost £50,000 or more.
Here’s everything you need to know before requesting quotes.

| Bespoke conservatory | £35,000–£70,000+ |
These are average UK prices and typically include supply and installation.
What affects the cost?
Size
The larger the conservatory, the more you’ll pay for:
- Foundations
- Brickwork
- Glazing
- Roofing
- Labour
Even a few extra square metres can significantly increase the final cost.
Frame material
uPVC
The most affordable option.
Benefits include:
- Low maintenance
- Good insulation
- Long lifespan
- Excellent value
Aluminium
A modern premium choice offering:
- Slim frames
- Contemporary appearance
- High durability
- Minimal maintenance
Aluminium generally costs more than uPVC.
Timber
Timber conservatories offer a traditional look that’s perfect for period homes.
However, they require regular maintenance and are usually the most expensive option.
Roof type
The roof you choose has a major impact on both price and comfort.
Common options include:
- Glass roof
- Polycarbonate roof
- Tiled warm roof
- Hybrid roof
Although tiled roofs cost more, they often provide better insulation and make the conservatory feel more like a traditional extension.
Glazing
Modern double glazing is standard, but many homeowners choose upgrades such as:
- Triple glazing
- Self-cleaning glass
- Solar control glass
- Low-emissivity (Low-E) glass
- Toughened safety glass
These improve comfort but increase the overall cost.
What does the price usually include?
Most conservatory quotes include:
✔ Foundations
✔ Base construction
✔ Frame
✔ Roof
✔ Double glazing
✔ External doors
✔ Installation
However, some quotations exclude:
- Flooring
- Electrics
- Heating
- Plastering
- Decorating
- Furniture
- Planning fees (if required)
Always ask for a detailed written quotation.
Do you need planning permission?
Many conservatories can be built under permitted development rights, meaning planning permission isn’t always required.
However, permission may be needed if:
- The conservatory exceeds permitted size limits.
- Your property is listed.
- You live in a conservation area.
- The project doesn’t meet permitted development rules.
Building Regulations may also apply in certain situations.
How long does installation take?
Typical installation times are:
| Conservatory | Approximate time |
|---|---|
| Small conservatory | 2–3 weeks |
| Medium conservatory | 3–4 weeks |
| Large conservatory | 4–6 weeks |
Poor weather or groundworks can extend the project.
Will a conservatory add value?
A well-designed conservatory can make your home more appealing to buyers by providing additional living space and improving natural light.
While there’s no guaranteed increase in property value, it may help your home stand out in a competitive market.
Conservatory or extension?
Many homeowners compare these two options.
Conservatory
Advantages:
- Lower cost
- Faster installation
- Bright, airy space
- Plenty of natural light
House extension
Advantages:
- Better insulation
- Feels like part of the original home
- Greater flexibility
- Often suitable for year-round living
If your budget allows, it’s worth comparing quotes for both options before making a decision.
Hidden costs
Before signing a contract, check whether the quote includes:
- Ground preparation
- Waste removal
- Electrical work
- Heating
- Flooring
- Blinds
- Internal decorating
- VAT
Unexpected extras can quickly increase the overall project cost.
How to save money
Compare several installers
Always obtain at least three detailed quotes.
Don’t compare price alone—compare the materials, guarantees and what’s included.
Choose the right roof
A tiled roof costs more initially but may improve comfort and reduce heating costs over time.
Plan your layout carefully
Making design changes once construction has started can be expensive.
Finalise the design before work begins.
