Conservatory Costs UK 2026: Types, Prices & What to Expect
Complete Price Guide for Every Conservatory Style
Quick Answer
A conservatory in the UK costs £6,000 to £40,000+ depending on type and size. A basic lean-to starts at £6,000 to £12,000. Victorian or Edwardian styles range from £10,000 to £25,000. Orangery-style conservatories cost £20,000 to £40,000+. Most do not need planning permission under Permitted Development.
Conservatories are one of the most popular ways to add light, space, and garden access to a UK home. They typically cost less per square metre than a solid extension, and most do not require planning permission, which makes them an appealing option for homeowners looking to expand without the full extension price tag.
The challenge is that "conservatory" covers a huge price range. A small polycarbonate lean-to at £6,000 is technically a conservatory. So is a brick-pillared orangery with a solid tiled roof at £40,000. The style, size, materials, and whether you want it usable year-round all have a big impact on the final cost.
This guide breaks down real 2026 UK conservatory prices by type, region, and spec level. It covers every common style from simple lean-tos to full orangeries, so you can budget accurately before getting quotes.

Cost by Conservatory Type
The biggest factor in conservatory cost is the style. A simple lean-to is very different from an orangery with brick pillars and a roof lantern. Each style has a different footprint, roof structure, and level of detail.
| Conservatory Type | Budget | Mid Range | Premium |
|---|---|---|---|
| Lean-to (simple, single pitch) | £6,000 to £10,000 | £10,000 to £15,000 | £15,000 to £22,000 |
| Victorian (3 or 5 facets, pitched roof) | £10,000 to £15,000 | £15,000 to £22,000 | £22,000 to £30,000 |
| Edwardian (square/rectangular, pitched roof) | £10,000 to £16,000 | £16,000 to £24,000 | £24,000 to £32,000 |
| Gable front (high vaulted gable) | £12,000 to £18,000 | £18,000 to £28,000 | £28,000 to £38,000 |
| Orangery (brick pillars, roof lantern) | £20,000 to £28,000 | £28,000 to £38,000 | £38,000 to £55,000+ |
| P-shaped or T-shaped (combined styles) | £18,000 to £26,000 | £26,000 to £38,000 | £38,000 to £55,000 |
Budget figures assume smaller sizes and standard finishes. Premium figures include larger footprints, upgraded glass, solid or tiled roofs, and higher-spec finishes.

Regional Price Differences
Where you live has a big impact on conservatory cost. Labour rates in London and the South East are significantly higher than in the North or Wales. Materials cost roughly the same across the country, so the difference is mostly labour and installation.
| Region | Small Lean-to | Victorian Mid | Orangery Premium |
|---|---|---|---|
| London | £12,000 to £18,000 | £20,000 to £28,000 | £45,000 to £60,000 |
| South East | £10,000 to £15,000 | £17,000 to £24,000 | £38,000 to £52,000 |
| South West | £9,000 to £13,000 | £15,000 to £22,000 | £35,000 to £48,000 |
| Midlands | £7,500 to £11,000 | £13,000 to £19,000 | £32,000 to £44,000 |
| North England | £7,000 to £10,500 | £12,000 to £18,000 | £30,000 to £42,000 |
| Scotland | £7,500 to £11,500 | £13,000 to £19,500 | £32,000 to £45,000 |
| Wales | £7,000 to £10,500 | £12,000 to £18,000 | £30,000 to £42,000 |
These are averages for mid-range specifications. Premium finishes, triple glazing, and solid roofs push costs higher in every region.
What Affects the Price?
Seven cost categories make up almost every conservatory budget. Understanding where the money goes helps you decide where to save and where to spend.
Planning Permission & Building Regs
Conservatories benefit from a generous set of exemptions that keep costs down compared to a solid extension. Both sets of rules matter.
Planning Permission
Most conservatories fall under Permitted Development. You typically will not need planning permission if it is single-storey, under 4 metres high, does not extend more than 3 metres from the original rear wall (4m for detached houses), and is less than half the total area of land around the original house.
Conservation areas, listed buildings, and properties with Article 4 directions are exceptions. Always check with your local planning authority if you are unsure.
Building Regulations
Conservatories are usually EXEMPT from Building Regs if they meet all of these conditions: built at ground level, under 30m² in floor area, separated from the house by external-quality doors, and have independent heating (or no heating connected to the main house).
Break any of these and you will need Building Regs approval. The exemption is the main reason conservatories are cheaper than solid extensions.
Why This Matters for Your Budget
If you want to remove the doors between the house and conservatory, or connect the heating to the main system, you lose the Building Regs exemption. That pushes the project into full extension territory on both cost and compliance. Decide early, it changes everything about the project.
Using Your Conservatory Year-Round
The biggest complaint about conservatories is temperature. Too hot in summer, too cold in winter. Solutions cost extra but transform how often you actually use the space.
Roof Upgrades
- Solar control glass: £1,500 to £3,500 extra
- Tiled/solid roof: £3,000 to £8,000 extra
- Thermally efficient polycarbonate: £500 to £1,500
Climate Control
- Underfloor heating: £1,500 to £3,500
- Air conditioning unit: £1,200 to £3,000
- Ceiling fans: £200 to £600
Ventilation
- Roof vents with thermostats: £300 to £800
- Additional opening windows: £200 to £600 each
- Trickle vents: usually included in frames
The Tiled Roof Upgrade
If you can stretch the budget, swapping a glass or polycarbonate roof for a solid tiled roof is the single biggest upgrade you can make. It turns the conservatory into a proper extra room that works in January as well as July. Many homeowners regret not doing this from the start.
How to Budget for Your Conservatory
Good budgeting is the difference between a project that finishes on plan and one that runs over. These five rules will save you money and stress.
Get 3 Quotes Minimum
Conservatory companies have different markups, some much higher than others. Give each company the same written spec so you are comparing like for like.
Understand What Is Included
Most conservatory quotes exclude flooring, electrics, and heating. Ask each quote to itemise these separately so you can see the true total cost.
Do Not Pay 50 Percent Upfront
A deposit of 10 to 25 percent is standard. Avoid anyone demanding half the money upfront before materials are ordered. Staged payments protect both sides.
Winter Is Cheaper
Conservatory companies often discount 5 to 15 percent in November to February when demand drops. If your project is flexible, winter quotes are worth getting.
Think Long Term
Spending £2,000 more on better glass or a tiled roof can double how often you actually use the space. Worth it if you plan to stay in the home for more than a few years.
Conservatory vs Orangery vs Extension
Understanding the differences between these three options helps you choose the right path for your home and budget.
Conservatory (Traditional)
Mostly glass, uPVC or aluminium frame, polycarbonate or glass roof.
£6,000 to £25,000. Fast to build, planning-friendly, temperature-sensitive.
Orangery
Brick pillars or dwarf walls, glass elements, solid roof with central roof lantern.
£20,000 to £55,000. Feels like a proper room, usable year-round.
Extension
Solid brick walls, matching roof, fully integrated with the house.
£25,000 to £80,000+. Most expensive, adds the most value, fully flexible use.
Which Is Right For You?
If you want light and a garden connection on a modest budget, a conservatory wins. If you want a proper extra room that feels integrated and is usable in every season, an orangery or full extension is better. The price difference between a premium conservatory and a basic extension is often smaller than people expect.
Will It Add Property Value?
A well-built conservatory that feels like a proper part of the house usually adds value. A dated, leaky, or poorly matched one can subtract from it.
You Typically Gain Value When
- The conservatory matches the style of the house
- It has a solid or tiled roof and is usable year-round
- It is sized proportionally to the house and garden
- Glazing and frames are modern and energy-efficient
You May Lose Value When
- The conservatory is dated polycarbonate and clearly unused
- It dominates the garden and leaves no outdoor space
- It looks bolted on rather than designed in
- It leaks, has failing seals, or is obviously cold
The Bottom Line
A well-designed conservatory typically adds 5 to 10 percent to property value. Orangeries with solid roofs often add more because buyers value them as proper extra rooms. Spend the money on a good-quality build rather than cutting corners, the return on value usually follows.
