What drives the price of a polycarbonate dome
Five factors set the figure:
- Size. A 2.7 m Mini, which seats 4-5, costs far less than the 5 m Large, which seats 12-16. Bigger footprint, more panels, higher price. Our garden dome sizes guide helps you choose.
- Specification. Original suits sheltered gardens, Ultra (panels 30% thicker than Original, with stainless steel bolts, nuts and anchors) is our pick for most gardens, including windy ones, and Extreme (3 mm panels, twice as thick as Original, with the same stainless steel hardware) is our strongest premium choice for homes and hospitality, including exposed, coastal or high sites. Match the specification to your site and the level of robustness you want; our guide to Original vs Ultra vs Extreme explains the differences.
- Accessories. Sunshade privacy panels, a base and heating add to the total but extend usability.
- Installation. Most owners build their own dome in an afternoon or a day, with no specialist tools. If you'd rather not, our Built for you service can build and anchor it for you.
- Logistics. Buying from UK stock avoids the customs charges and shipping fees that can inflate the real cost of domes shipped from overseas.
The cost-per-use lens
Headline price hides the better question: cost per year of use. As an illustration, a £600 PVC tent that lasts two seasons and only gets used in summer can work out more expensive per year of use than a polycarbonate dome used most weekends, year-round, over several years. Buy the budget option for a permanent job and you typically pay twice: the replacement, plus the upgrade you should have bought first.
Hidden costs to check before you buy
- Import duties and customs on domes shipped from overseas (none with GeoDomeX UK stock).
- Delivery charges. Confirm they're included or quoted; our free service applies to eligible UK destinations.
- Base or foundation. A dome needs level, firm ground; if you don't have it, factor in a base.
- Anchoring. Make sure it's included; it's not optional. Anchoring brackets come with every GeoDomeX dome.
- Warranty and spare parts. Check what any warranty covers and for how long, and whether spares are available. Ours is a 1, 3 or 5-year warranty depending on the specification, plus lifetime access to replacement parts under our parts guarantee.
What's a fair budget?
- £200-£800: occasional summer cover in PVC; accept a short lifespan.
- £899-£2,999: a quality polycarbonate dome, from a Mini in Original to the 5 m Large. This is the sweet spot for most homeowners wanting a year-round room.
- £3,000-£6,000+: a complete setup (a larger or higher-specification dome with a base, sunshade and installation) for a fully finished home or hospitality space, including larger gardens and exposed sites.
- £15,000+: you're now in conservatory territory, which is a different product.
Frequently asked questions
How much is a good garden dome in the UK?
A GeoDomeX solid polycarbonate dome starts from £899 for the 2.7 m Mini, with the 3.5 m Standard from £999 and the 5 m Large at £2,999. PVC tents cost less (typically £200-£800) but are fair-weather and short-lived.
Why are some garden domes so much cheaper?
They're usually PVC, not polycarbonate: a flexible, fair-weather material that lasts a few seasons rather than years. The price reflects the material and lifespan.
Are there hidden costs with garden domes?
With domes shipped from overseas, watch for import duties and delivery charges. GeoDomeX domes come from UK stock with free next-day delivery to eligible UK destinations when you order by 2pm, Monday to Friday, and anchoring brackets are included. Budget for a base if you don't have level, firm ground.
Does a garden dome cost less than an extension?
Yes, by a wide margin: a GeoDomeX dome costs from £899 to £2,999, while a conservatory or garden room typically starts around £15,000. A dome of this size is usually permitted development, but check with your local planning authority, especially for listed buildings and conservation areas.
What size dome can I get for £899?
The 2.7 m Mini in the Original specification. It suits patios, terraces and small gardens, seats 4-5 and fits a table for four or a yoga setup.
