There are four main types of balloon arch. Prices start from around £80 for a helium string of pearls, swirl garland arches start from £275, and a large organic arch outside on a windy day can rise to £500-plus. Which one you need depends on the look you are after, where it is going, and how long it has to survive. Here is the whole picture, so you know exactly what to ask for.
The swirl garland arch
This is the classic doorway or stage arch: balloons twisted together like a candy cane, built on a frame, and equally happy inside or outside. It is the design most people picture when they say “balloon arch,” and it is the one I get asked for most for shop openings and entrances.
From £275, rising with size and complexity. Want your logo balloons woven through it for a corporate launch? That is where the price climbs, not the basic shape.
The organic demi arch
A half-arch built on a frame using balloons of genuinely varying sizes, anything from 5″ up to 36″, mixed with different finishes: latex, matte, shiny, foil and custom colours. The one rule that never changes: every balloon in it has to be perfectly round. It is the design you will have seen everywhere on Instagram, and it takes roughly three times as many balloons as a standard garland arch, plus a lot longer to build.
From £175, with £300-plus for the full wow factor. This is where the labour is, so this is where the price reflects it.
The string of pearls arch
A single elegant line of helium-filled balloons, used to frame a bride and groom or dress a stage for a prize-giving. It is the simplest-looking of the four and the one people are most surprised costs anything at all, until they hear the helium price.
From £80 for an average-size arch. Helium has gone up sharply over the past few years (think the petrol price rise, but for balloons), and that is reflected here more than in any other style.
The double bubble (romantic arch)
The deluxe version of the pearl arch: a 16″ patterned balloon double-stuffed with an 11″ balloon, in a single helium-filled line. Almost always seen behind a top table at a wedding, and it takes real skill to get every double perfectly matched.
From around £150.
How long will a balloon arch actually last?
This is the question that decides more of the price than people expect, because it decides how the whole thing gets built. Kept indoors, out of direct sun and away from radiators, a well-made arch can look sharp for several days to a couple of weeks. Take the same arch outside into wind, heat or direct sunlight, and you are looking at one day, sometimes less. Heat makes dark colours oxidise and pop, and wind puts strain on joins that were never designed to fight the weather.
Helium designs behave differently again: they float only as long as the helium holds, which is usually one to two days depending on the balloon and the temperature. If you need something to survive a two-day event, tell me that upfront. It changes whether I build with air or helium, and whether it needs a proper rig rather than just weight at the base.
What actually moves the price?
Style and size are the headline factors, but they are not the whole story. Location matters: inside is calmer and cheaper to build for than outside on an exposed, windy day. Ceiling height, whether there is a usable rig point or I need to build a supporting structure from scratch, how wide the space is, and whether it is against a wall or has to work as a walkway all change the build. So does how long it needs to last, and whether it is air-filled or helium-filled. Travel outside South Yorkshire adds a delivery charge and, honestly, so it should. For the wider picture, see my balloon décor cost guide.
There is no single price list that covers all of this honestly, and any decorator who gives you one figure without asking a single question is not costing the job properly. What I can promise is a straight answer once I know what you are picturing.
Are balloon arches bad for the environment?
All my work is in natural biodegradable latex. No balloon releases, ever. Everything is taken away afterwards, and leftover balloons are recycled through a national company that specialises in recycling balloons. The van is electric, and even the helium is reclaimed from MRI machines. Spectacular should not cost the earth.

Quick answers
A small helium string of pearls arch, from £80. If you want a full garland, a classic swirl garland arch starts from £275.
Indoors, away from heat and direct sun, several days to around two weeks. Outdoors, or anywhere hot and bright, expect one day. Helium designs last one to two days regardless of location.
A garland (swirl) arch uses balloons of one size, twisted in a repeating pattern. An organic (demi) arch mixes sizes from 5″ to 36″ for a looser, more natural look, and takes about three times as many balloons to build.
Yes, but it needs proper framing and will have a shorter life than the same arch indoors. Rain, heat and wind all affect outside work, so the forecast matters.
