This page is about the money. For the hands-on side, see our step-by-step greenhouse installation walkthrough.
TL;DR for the impatient: The greenhouse sticker price typically covers the structure only. Ground preparation, foundation, anchoring, professional install if you don't DIY, and the £200–£600 of optional extras (staging, water, light electrical) can add 20–60% to total project cost. A typical UK buyer spends £400–£1,200 beyond the sticker price for a mid-tier greenhouse. The lower end of that range is DIY with anchors included; the upper end is professional install with a paving-slab base.
You've found a greenhouse at £1,500 and you're wondering whether the total cost will actually be £1,500 or £2,500. This guide is the honest answer.
We make greenhouses (NORDIC timber and SteelRoot steel arch ranges) so you should know our bias. But we've watched enough customer install journeys, and lost enough sales to buyers who'd genuinely budgeted for the sticker only, to know that transparent total-cost framing serves everyone better than the surprise at delivery.
We'll walk through the seven cost components most UK buyers hit, the rough budget for each, and what NORDIC and SteelRoot include against what they leave to you.
Greenhouse installation cost UK: the quick answer
For most UK gardens, the real greenhouse installation cost sits well below what buyers fear. If you self-assemble on level ground, your total installation cost is usually just the base materials plus a little setup time. If you hire a fitter, add a labour line. Here is the honest picture for 2026.
| Installation route | What it covers | Typical UK cost (2026) |
|---|---|---|
| DIY on level ground | Two adults, one weekend, basic hand tools | £0–£80 (base materials only) |
| DIY with paved perimeter | Slab perimeter for extra anchorage | £200–£600 |
| Handyman fit (small greenhouse) | Build only, you prep the base | £150–£350 labour |
| Specialist fit (mid-size) | Build on your prepared base | £300–£700 labour |
| Specialist fit (large/exposed) | Build, level and anchor | £700–£1,500 labour |
The NORDIC timber range is built for two-adult weekend self-assembly, and SteelRoot steel-arch greenhouses are supplied as a kit for home assembly, so for our ranges the installation cost is typically the £0–£80 base line rather than a fitter's fee. Galvanised Ground Screw Anchors are included, which removes a separate anchoring cost that catches out many buyers. The sections below break each line down in full.
This guide is about what installation, groundwork and labour cost. For the price of the greenhouse itself and its ten-year running cost, see our wooden greenhouse cost guide.
The seven cost components of a UK greenhouse install
1. The structure itself (the sticker price)
What you see in the listing. Indicative bands for a 6–10 m² internal area, based on publicly listed prices at the time of writing (May 2026). Prices change, so check current listings before comparing:
| Tier | Price band |
|---|---|
| Entry-tier polycarbonate aluminium (Halls Qube, Eden Birdlip, Vitavia entry) | £200–£800 |
| Mid-tier polycarbonate aluminium (Halls Magnum, Eden Regent) | £800–£1,800 |
| Wooden polycarbonate (NORDIC range) | £999–£1,549 |
| Mid-tier glass aluminium (Vitavia Saturn, Halls Magnum glass) | £1,000–£2,400 |
| Heritage glass + timber (Gabriel Ash, Swallow smaller) | £4,000–£12,000 |
| Country-house tier (Hartley, Alitex) | £8,000–£50,000+ |
For larger growing area (25–48 m²), engineered steel-arch cellular PC tier (SteelRoot range): £899–£1,899.
2. Delivery to your address
Often quoted as "free UK mainland delivery" or "included" by serious brands, but worth checking carefully:
| Brand approach | Typical cost |
|---|---|
| Free UK mainland (most NORDIC, SteelRoot, mid-tier wooden brands) | £0 |
| Free mainland, surcharge for Highlands/Islands | £80–£250 extra |
| Delivery costed separately (some heritage brands) | £80–£200 |
| Polytunnel delivery typical pallet | £50–£120 |
If you're in the Scottish Highlands, the Outer Hebrides, the Northern Isles, or Northern Ireland, contact the brand before ordering. Many UK brands ship "mainland only" and apply surcharges or restrictions for these regions.
3. Ground preparation
The patch of garden the greenhouse sits on. Three approaches with different costs:
DIY levelling (typical, £0–£80): clear the area, remove turf or vegetation, level the soil within 25 mm of true across the footprint using a long timber straightedge and a spirit level. Removing existing concrete or hard standing is harder and may need professional help.
Paving slab perimeter (£200–£600): lay a row of 600 × 600 mm concrete paving slabs around the footprint to give a clean dry working surface and additional storm anchorage. Suitable for buyers in coastal or elevated sites who want extra stability. DIY for a confident gardener; £200–£400 in professional time if hired.
Full concrete pad (£600–£1,800): continuous concrete base across the entire footprint. Required for some heritage glasshouses; not required for cellular PC greenhouses. Professional install only; needs to cure for 5–10 days before structure assembly.
Decision logic: for typical UK garden soil and a typical domestic site, DIY levelling is sufficient. For exposed sites, a paving-slab perimeter is the sensible upgrade. Full concrete is overkill for most cellular PC greenhouses but mandatory for some heritage glass.
4. Anchoring
Often the surprise cost. Ground anchors fix the structure to the ground and are non-negotiable, engineered for British storm conditions.
| Approach | Typical cost |
|---|---|
| Ground anchors INCLUDED in structure price (NORDIC, SteelRoot) | £0 |
| Ground anchors sold separately by greenhouse brand | £60–£200 |
| Aftermarket ground screws (M12/M16) | £40–£120 |
| Cast-in-place concrete footings (for heritage glass on concrete pad) | included in concrete pad cost |
We include Galvanised Ground Anchors with every NORDIC and Ground Screw Anchors with every SteelRoot specifically because separate-purchase anchoring is the single most-often-skipped storm-prep step. Many entry-tier brands sell the anchors as a £100 upgrade, and a meaningful share of buyers don't buy them, with predictable storm-season consequences.
5. Professional install (if you don't DIY)
Most UK greenhouses are designed for DIY assembly. Both NORDIC and SteelRoot ship with illustrated guides, QR-linked video walkthroughs, and pre-cut numbered components for two-adult weekend assembly.
For buyers who prefer professional install:
| Install type | Typical UK cost (2026) |
|---|---|
| General handyman (small greenhouse, sheltered site) | £150–£350 |
| Greenhouse install specialist (mid-size, average site) | £300–£700 |
| Greenhouse install specialist (large, exposed, or complex site) | £700–£1,500 |
| Heritage brand professional install (Hartley, Alitex) | typically £1,500–£5,000 (often included in price) |
If you're hiring, look for someone with specific greenhouse experience. Generalists can struggle with glazing fixing and roof panel handling. Local handyperson services rated on Checkatrade or MyBuilder are a good starting point.
6. Optional extras inside the greenhouse
These are post-install costs that buyers often forget to budget for:
| Item | Typical cost |
|---|---|
| Staging (work benches) | £80–£300 |
| Shelving (additional tiers) | £40–£120 per tier |
| Water source (water butt + downpipe diverter) | £40–£120 |
| Cold-water tap nearby (if professional plumbing needed) | £150–£400 |
| Electrical supply (armoured cable + outdoor socket) | £200–£800 if professional install |
| Automatic vent openers (additional beyond included) | £35–£80 each |
| Heating (paraffin to electric) | £100–£600 depending on system |
| Thermometer + min/max + humidity gauge | £15–£60 |
| Shade cloth or whitewash for summer | £25–£80 |
Few buyers install all of these in year one. Most start with staging, basic shelving, and a water butt, call it £150–£400, and add as they go.
7. Hidden costs most buyers don't see coming
Common surprise items across customer feedback:
- Removing existing structure: if you're replacing an old greenhouse or shed, factor £100–£400 for break-down and disposal
- Tree-root surgery: if the chosen site has tree roots near the surface, you may need to bring in a tree surgeon for partial root removal (£150–£500)
- Access difficulties: if your garden has no rear access and components need to come through the house, you may need extra hands (£0 if friends, £150+ if hired) and protection for floors and walls
- Skip hire: if you've dug out turf, broken existing concrete, or accumulated assembly waste, a skip is £180–£350
- Replacement of damaged-in-transit panels: covered by the brand at no charge, because transit damage is the seller's responsibility under the Consumer Rights Act 2015; photograph panels on delivery and report any damage promptly to keep the claim straightforward
- Extra tool purchase: if you don't own a cordless drill, decent spirit level, or step-ladder, allow £80–£250 for one-off tool acquisition

What NORDIC and SteelRoot include vs separate cost
Transparency on what you actually pay for at our brand specifically:
| Included with NORDIC | Included with SteelRoot | |
|---|---|---|
| UK mainland delivery | ✅ | ✅ |
| Ground anchors | ✅ Galvanised Ground Anchors | ✅ Ground Screw Anchors |
| Assembly hardware | ✅ pre-sorted, numbered | ✅ pre-drilled, bolt-assembled |
| Illustrated guide + QR video | ✅ | ✅ |
| Vents | Manual back-gable on S/M/L; auto side-wall on XL/XXL | Rear opening window standard |
| Customer service during build week (phone + WhatsApp) | ✅ | ✅ |
| Spare-parts catalogue | ✅ | ✅ |
| Ground preparation | ❌ DIY | ❌ DIY |
| Professional install | ❌ Recommended hire if not DIY | ❌ Recommended hire if not DIY |
| Staging / shelving | ❌ Separate purchase | ❌ Separate purchase |
| Water / electrics | ❌ Separate trades | ❌ Separate trades |
The deliberate decision to include the ground anchors and skip a "concrete base required" specification is the single largest reason the sticker-to-total uplift in our DIY scenarios above stays at roughly 10–30%, rather than the 20–60% that's common once a base, anchors and professional install have to be bought separately, even though our sticker price is higher.
DIY vs professional install: when each makes sense
DIY install (the default we design for) works when:
- You have a confident DIY partner for two-adult panel lifts
- You own or can borrow a cordless drill, spanner set, spirit level, and step-ladder
- You can dedicate a weekend morning to a full day, depending on size
- You're physically comfortable with up-to-2 m lifts for roof panels
Professional install makes sense when:
- You're on your own and the two-adult lifts aren't safe solo
- You have time constraints (you want it built within a week of delivery, not waiting for a weekend)
- You're in a difficult site (tight access, slope requiring foundation work, mature trees needing surgery)
- You're not confident with the toolbox skills required
For NORDIC and SteelRoot specifically, DIY install is the design intent and the majority path. Our customer service line during build week is staffed specifically to help DIY builders work through unfamiliar steps.

Frequently asked questions
What is the average greenhouse installation price in the UK?
There is no single greenhouse installation price because most of it depends on whether you build it yourself. A self-assembled greenhouse on level ground costs £0–£80 in base materials and no labour. If you pay a fitter, expect £150–£350 for a small structure, £300–£700 for a mid-size one, and £700–£1,500 for a large or exposed site. Heritage glass-and-timber installs by brand fitters run £1,500–£5,000. Because NORDIC and SteelRoot ship as home-assembly kits with anchors included, the installation price for our ranges is usually just the base-materials line, with no fitter's fee.
How much is the greenhouse construction cost on top of the kit?
For a modern polycarbonate greenhouse, the greenhouse construction cost beyond the kit is small. On typical UK garden soil you need level ground and anchoring, not a concrete pad. DIY levelling costs £0–£80; an optional paved-slab perimeter for extra anchorage costs £200–£600; a full concrete base (rarely needed for cellular polycarbonate greenhouses) costs £600–£1,800. With NORDIC and SteelRoot the anchors are already included, so for most gardens the construction cost is the base line alone.
What's the cheapest way to install a greenhouse in the UK? DIY install on existing level ground using a structure that includes ground anchors. Total project cost typically 10–20% above sticker price. Avoid structures that require concrete bases or separately-sold anchors if you're optimising for total spend.
Do I need a professional to install a greenhouse? For most domestic UK greenhouses, no. Both NORDIC and SteelRoot are designed for two-adult weekend DIY install with a cordless drill, spanner set, spirit level, and step-ladder. Professional install is sensible for single-buyer households, complex sites, or buyers without DIY confidence, with a typical cost of £300–£700 for mid-size structures.
How much does it cost to lay a greenhouse base? DIY levelling on typical UK garden soil: £0–£80 in materials. DIY paving-slab perimeter for additional storm anchorage: £200–£600. Full concrete base (rarely needed for cellular PC greenhouses): £600–£1,800.
Are greenhouse anchors really necessary? Yes for any UK site that gets meaningful wind exposure, which is most UK sites. A structurally sound greenhouse without anchors simply lifts in serious wind. Look for brands that include the anchors in the structure price rather than selling them separately as a £100 upgrade most buyers skip.
How much extra do you spend on greenhouse accessories in the first year? Most first-year buyers spend £150–£400 on staging, basic shelving, water butt, and one or two additional vent openers. Heating, electrics, and shade cloth typically come in year two as the buyer's growing programme evolves.
What's the difference between greenhouse "delivery" and "installation"? Delivery means the structure arrives on a pallet at your kerbside. Installation means it's built on your prepared base. Most UK brands offer delivery only as standard; installation is a separately-quoted optional service or your DIY weekend project.
