Installer's Note
We price and install greenhouses every day. The biggest mistake we see is people budgeting only for the greenhouse itself. The base costs £150-£400. Installation costs £200-£500. Staging, a heater and a vent opener add another £200-£400. Your real budget needs to be 40-60% higher than the greenhouse sticker price. This guide covers every cost so there are no surprises.
How much does a greenhouse cost by size?
Size is the single biggest factor in greenhouse pricing. Moving from a 6x4 to an 8x6 typically adds 40-60% to the price. Going from 8x6 to 10x12 can double or triple it. Here are real prices from our current catalogue, covering the most popular sizes.

Budget greenhouses: under £700
You can buy a quality greenhouse for under £700. At this price point you are looking at 6x4 to 8x6 aluminium frames with either polycarbonate or horticultural glass glazing. These are not flimsy. The Vitavia Venus range is our best seller at every size and starts at £455 for the 6x4.
|
Best Budget: Palram Canopia Mythos 6x4Best For: First-time buyers who want the lowest entry price Why It's Good Value: Twin-wall polycarbonate is virtually unbreakable and provides better insulation than single glass. Slide-open roof vent included. Price: £1,169 |
|
Best Value Glass: Vitavia Venus 2500 6x4Best For: Growers who want real glass for maximum light and clarity Why It's Good Value: 4mm toughened glass, integral base, single sliding door, roof vent. Our number one seller for small gardens. Price: £579 |
The biggest decision at this price point is glass vs polycarbonate. Polycarbonate is cheaper, lighter and safer. Glass gives better light transmission and looks more traditional. Both work well for growing.

Mid-range greenhouses: £700-£1,500
This is the sweet spot for most UK buyers. Between £700 and £1,500 you get an 8x6 or 8x10 greenhouse with toughened safety glass, a proper door, multiple vents and enough space to grow a full range of crops. These are the sizes and models we install most often.

Matt's Pick: Vitavia Venus 5000 8x6Best For: The UK's most popular greenhouse size. Fits most gardens. Why I Recommend It: We have sold and installed more of these than any other model. Enough room for staging on one side and growing on the other. Toughened glass is safe around children and pets. Price: £649 |

Premium Mid-Range: Elite Craftsman 8x6Best For: Buyers who want a step up from entry-level without spending thousands Why It's Worth the Extra: Thicker aluminium frame, wide double doors, high eaves. Made in Bolton by a third-generation UK manufacturer. Price: £1,490 |

Premium greenhouses: £1,500-£5,000

|
Best Large Aluminium: Vitavia Neptune 8300 8x10Best For: Year-round growing with room for staging on both sides Why I Recommend It: The Neptune range is the step up from the Venus. Wider door, taller ridge, more roof vents. Black finish looks striking. Price: £ |

How much does a greenhouse cost by brand?
Brand determines build quality, warranty length and resale value. Here is what each manufacturer charges across their range:

|---|---|---|---|---|

Our most-installed brands are Vitavia (budget and mid-range) and Elite (mid-range and premium). For the full selection across all brands, browse our greenhouses collection.
How much does a greenhouse base cost?
Every greenhouse needs a level base. Budget £150-£400 depending on the method and size. The greenhouse itself is only as good as what it sits on. An uneven base causes doors to stick, glass to crack under frame stress and water to pool in one corner.
| Base Type | Cost (6x8) | Cost (8x10) | DIY? | Best For |
|---|---|---|---|---|
| Paving slabs on sand | £100-£200 | £200-£350 | Yes | Most hobby greenhouses. Easy to lay. |
| Concrete pad | £200-£400 | £350-£600 | Yes (with help) | Large or wooden greenhouses. Most durable. |
| Greenhouse floor kit | £89-£189 | £149-£319 | Yes | Quickest option. Galvanised steel grid. |
| Professional base | £300-£500 | £400-£700 | No | When you want it done right without the effort. |
For step-by-step instructions, read our guide on how to build a concrete greenhouse base or paving slab greenhouse base. Our greenhouse flooring options guide compares every material.
How much does greenhouse installation cost?
Professional installation costs £200-£500 for a standard aluminium greenhouse. Larger or wooden models cost more. We offer a nationwide greenhouse installation service and have fitted over 4,000 greenhouses across the UK.
| Greenhouse Size | DIY Install Time | Pro Install Cost | Notes |
|---|---|---|---|
| 6x4 | 4-6 hours | £200-£300 | One person can manage with patience |
| 6x8 / 8x6 | 6-8 hours | £250-£400 | Two people recommended |
| 8x10 / 8x12 | 8-12 hours | £350-£500 | Two people essential |
| 10x12+ | 1-2 days | £400-£700 | Professional installation recommended |
| Wooden (any size) | 1-3 days | £500-£1,500 | Heavy. Professional installation strongly recommended. |
Our how to install a greenhouse guide covers the DIY route in detail. Read about common installation mistakes before you start.
Matt's Tip: Always Get Two People
I have watched hundreds of customers attempt a solo greenhouse build. It is possible on a 6x4. It is extremely difficult on anything larger. Glass panels need one person to hold and one to fix. The roof sections are awkward and heavy overhead. Budget for a helper even if you are doing it yourself. A case of beer is cheaper than a broken glass panel.
How much do greenhouse accessories cost?
Plan an extra £200-£500 for the accessories that make a greenhouse actually usable. A bare greenhouse is just a glass shell. You need staging to work on, ventilation to prevent overheating and some form of heating for winter.
| Accessory | Price Range | Essential? | Our Pick |
|---|---|---|---|
| Staging (2-tier) | £79-£109 | Yes | Vitavia 2 Tier Staging £99 |
| Auto vent opener | £46-£89 | Yes | Vitavia Auto Vent Opener £46 |
| Electric heater | £140-£199 | For winter growing | Eden 2kW Heater £140 |
| Paraffin heater | £110 | For frost protection (no electric) | Elite Super Warm 5 £110 |
| Max-min thermometer | £24-£44 | Yes | Vitavia Max Min Thermometer £30 |
| Bubble wrap insulation | £79 | For heated greenhouses | Elite Bubble Wrap + Clips £79 |

The true cost of a greenhouse includes the purchase price, base, installation, accessories and annual running costs. Here is a realistic breakdown for three common scenarios:
| Cost Item | Budget 6x4 | Mid-Range 8x6 | Premium 8x12 |
|---|---|---|---|
| Greenhouse | £455 | £649 | £1,500 |

How to save money on a greenhouse
There are five practical ways to reduce the total cost without sacrificing quality.
- Build the base yourself. A paving slab base for a 6x8 greenhouse costs £100-£200 in materials. Paying someone to do it adds £150-£300.
- Choose horticultural glass over toughened. Same greenhouse, 15-25% cheaper. The trade-off is that horticultural glass breaks into sharp pieces if hit. Toughened glass is safer. If you have children or pets, pay the extra.
- Buy during the sale season. Check our greenhouse sale page. We run seasonal discounts, particularly in autumn and early winter.
- Skip professional installation if you are handy. DIY installation saves £200-£500. Just make sure you have a helper.
- Start with the essentials. You do not need every accessory on day one. Staging and a vent opener are essential. A heater can wait until autumn. Grow lights can wait until you are ready for winter growing.

Do you need planning permission for a greenhouse?
Most greenhouses in the UK do not need planning permission. Under permitted development rights, a greenhouse is classed as an outbuilding. It must cover less than 50% of the garden, sit behind the front building line and not exceed 2.5m at the eaves if within 2m of a boundary. Our full greenhouse planning permission guide covers every exception and edge case.
Frequently asked questions
What is the cheapest greenhouse you can buy?
Our cheapest freestanding greenhouse is the Palram Canopia Mythos 6x4 at £329. It uses twin-wall polycarbonate glazing, which is lighter and safer than glass. The cheapest glass greenhouse is the Vitavia Venus 2500 6x4 at £455.
How much is a good quality 8x6 greenhouse?
A quality 8x6 greenhouse costs £509-£1,300. The Vitavia Venus 5000 8x6 in toughened glass starts at £649. The Elite Craftsman 8x6, a step up with thicker aluminium and wide doors, starts at around £1,100.
Is a greenhouse worth the money?
Yes. A mid-range 8x6 greenhouse costs £24 per month over 10 years. It extends your growing season by 2-3 months, protects crops from weather and pests, and lets you grow tomatoes, peppers and aubergines that struggle outdoors in the UK.
How much does it cost to heat a greenhouse in winter?
An electric heater costs £80-£180 per winter for an 8x6 greenhouse. A 2kW heater on a thermostat runs for 4-8 hours per night from November to March. At 20p/kWh, that is £1.60-£3.20 per cold night. Insulation with bubble wrap cuts this by 30-50%.
Do I need a base for a greenhouse?
Yes. Every greenhouse needs a firm, level base. The cheapest option is compacted hardcore with paving slabs on top (£100-£200 for a 6x8). A concrete pad is the most durable option (£200-£400). Without a level base, the frame will twist and glass will crack.
Can I install a greenhouse myself?
Yes, with a helper. Budget 6-8 hours for a 6x8 greenhouse. You need a drill, spanners and a spirit level. The main challenge is glazing the roof safely. Professional installation costs £250-£500 and saves a full day of work.
What is the best greenhouse for beginners?
The Vitavia Venus 6x4 or 8x6 in toughened glass is the best beginner greenhouse. It is affordable, easy to assemble and has everything you need to start growing. Add staging and a vent opener and you are ready to go.
