Why We Offer Professional Installation
We started offering our own installation service because too many customers were calling us after a local handyman damaged their glazing bars or voided their warranty. In 2016, we partnered with factory-trained fitters who actually understand how aluminium greenhouse frames go together, and it's made a real difference. Our installers complete between 15 and 25 greenhouse builds per month, so they know these products inside out. I'd always recommend professional installation for anything 8ft wide or larger, or if you're working with toughened safety glass. The cost is a fraction of the greenhouse price, and it means your warranty stays fully intact from day one.
— Matt, Co-Founder of Greenhouse Stores🔧 Matt's Installation Tip: Get Your Base Right First
The single biggest reason installations get delayed is the base not being ready. Your concrete slab or paving needs to be dead level (within 5mm across the full area), fully cured (at least 72 hours for concrete), and exactly the right dimensions. We send base measurements with every order confirmation, but I'd say 1 in 5 customers gets the size slightly wrong. If your base is 20mm too small, the greenhouse won't sit properly and it'll affect the door alignment. Measure twice, pour once, and if you're unsure, send us a photo of your prepared base before your installation date. We'll tell you honestly if it needs adjusting.
Professional vs DIY: An Honest Cost and Time Comparison
Professional installation costs 25-40% of a typical DIY time investment and removes the risk of warranty-voiding assembly errors.
We've seen both sides of this decision thousands of times. Some customers genuinely enjoy building their own greenhouse, and it's a satisfying weekend project if you've got the right skills. But we've also had hundreds of calls from DIY builders who've cracked glazing panels, cross-threaded bolts, or spent three weekends on a job our fitters finish in a single day.
Here's an honest comparison based on what we've seen across over 150,000 customer orders since 2012:
What Does Greenhouse Installation Actually Cost?
Professional greenhouse installation in the UK costs between £325 and £3,500 depending on the size and complexity of your greenhouse.
Here's a realistic breakdown of what you'll pay based on the most common sizes we install:
These prices include assembly, glazing, door fitting, weatherproofing, structural inspection, and full packaging cleanup. Swallow wooden greenhouse prices include installation as standard. For Vitavia and Elite aluminium models, installation is available as an add-on at checkout.
Which Greenhouse Brands Do We Install?
We install greenhouses from Vitavia, Elite, Janssens, Access, Stali, and Palram, and installation is included free with all Swallow and Lichfield wooden greenhouses.
We only install greenhouses that we supply. This isn't about being difficult. It's because our fitters know these specific brands and models. They've built hundreds of each, they carry the right fixings and spare parts, and they can spot a manufacturing defect before it becomes your problem.
If you've bought a greenhouse from another retailer, we can't install it. We need to guarantee the quality of both the product and the build, and we can only do that when we control both sides.
How to Prepare for Your Greenhouse Installation
A properly prepared base is the single most important factor in a successful greenhouse installation.
Before your installation date, make sure these three things are sorted:
1. Base preparation: Your concrete slab or paving must be dead level (within 5mm tolerance), square-cornered, and the exact dimensions we provide with your order confirmation. Allow 72 hours minimum for concrete to cure. A base that's 20mm out of square will cause door alignment problems that are very difficult to fix later.
2. Site access: Our fitters need clear access to carry panels and frames from their vehicle to your garden. If there are narrow side passages (under 80cm), gates, or steps, let us know when booking so we can plan accordingly. Greenhouse glass panels can be up to 1.5m long.
3. Weather contingency: We don't install in winds above 25mph or heavy rain. It's a safety issue with glass handling. If we need to reschedule due to weather, we'll contact you the morning of your booking. There's no charge for weather-related rescheduling.

Frequently Asked Questions
-
How much does greenhouse installation cost in the UK?
Professional greenhouse installation costs £325–£3,500 depending on greenhouse size and type. A standard 6x8ft aluminium greenhouse typically costs £420–£550 to install, while larger 10x12ft models cost £850–£1,500. This includes complete assembly, glazing, weatherproofing, structural inspection, and packaging disposal. Installation is included free with all Swallow and Lichfield wooden greenhouses.
-
Do you install greenhouses nationwide?
Yes, we provide greenhouse installation services across England, Scotland, and Wales through our network of certified installers. Coverage includes all major cities and surrounding areas including London, Birmingham, Manchester, Leeds, Glasgow, Edinburgh, Cardiff, Bristol, and Newcastle. We've also completed installations internationally in France, the Netherlands, Norway, and Iceland. Call us on 0800 098 8877 to confirm availability and pricing for your location.
-
What foundation do I need for professional installation?
A solid, level base is needed for any greenhouse installation. Concrete slabs and poured concrete are the best options, lasting 25+ years and providing maximum stability. Paving slabs also work well and cost £400–£800 for a 6x8ft area. The base must be flat within 5mm, square-cornered, and properly cured (72 hours minimum for concrete). Soft ground, grass, or uneven surfaces aren't suitable and may void warranties.
-
How long does greenhouse installation take?
Professional installation takes 4–10 hours for most greenhouses. Small 6x4ft models take around 3–4 hours, a standard 6x8ft greenhouse takes 4–6 hours, and larger 10x12ft greenhouses take 8–10 hours. Very large greenhouses (12x20ft+) may need 1–2 full days. By comparison, DIY installation typically takes 12–20 hours spread over 2–3 days with two people.
-
Is planning permission required for greenhouse installation?
Most greenhouses under 30m² don't need planning permission under permitted development rights. Your greenhouse must be under 4m at the apex (3m for flat roofs), at least 2m from boundaries, and for domestic use only. Restrictions apply for listed buildings, conservation areas, Article 4 Direction areas, and flats or maisonettes. Always check with your local planning authority before ordering.
-
What's included in your installation service?
Our installation service includes pre-installation product inspection, complete frame assembly, professional glazing, door and ventilation fitting, base securing, weatherproofing, a full structural integrity check, and cleanup with disposal of all packaging. You also get a 12-month installation warranty on top of the manufacturer's product warranty.
-
Can I get installation for any greenhouse brand?
We install greenhouses that we supply: Vitavia, Elite, Janssens, Access, Stali, and Palram models. Installation is included with all Swallow and Lichfield wooden greenhouses and available as an add-on for aluminium models. We don't install third-party greenhouse purchases because we need to guarantee the quality of both the product and the build.
-
Can I install a greenhouse on decking?
You can install a greenhouse on decking only if the decking is structurally sound, perfectly level, and anchored to solid ground beneath. Standard garden decking often isn't strong enough because it needs to support the full weight of the greenhouse frame, glazing, and wind load. We'd recommend checking with a structural surveyor if your decking is more than 300mm above ground level. A dedicated concrete or slab base is the safer option for most situations.
-
What happens if weather delays my installation?
We don't install in winds above 25mph or heavy rain for safety reasons. Handling glass panels in high winds is dangerous. If we need to reschedule, we'll contact you on the morning of your booking and arrange the next available date. There's no charge for weather-related rescheduling. On average, we reschedule about 1 in 10 installations during autumn and winter months.
