Up at The O2: The Maximum Thigh Measurement Is 75cm

There is a maximum thigh measurement. That is the sentence worth reading before you book.

Up at The O2 publishes four physical limits, and two of them are measurements almost nobody checks before paying:

“Maximum weight: not weigh more than 21 stone/130kg/286lbs.”

“Maximum measurements: maximum waist measurement 125cm, maximum upper thigh measurement 75cm.”

The reason is the harness. It is a fixed piece of safety equipment with fixed dimensions, and if it does not close, the climb does not happen. There is no discretion at the door and no alternative harness.

The other two gates: minimum age 8, minimum height 1.2m. Up at The O2 is also not suitable for pregnant customers.

A tape measure is a cheaper way to find this out than a non-refundable ticket.

The wheelchair climb looks like £250 and works out at £25

The pricing on the website reads, at first glance, as though a wheelchair user is charged seven times the standard rate. They are not, and the detail matters.

The listed price is from £250 against from £37 for the standard climb. But:

“The Wheelchair Climb can accommodate 1 wheelchair user and up to 9 friends and family members, including a personal assistant/carer. The personal assistant/carer climbs for free.”

So £250 buys up to ten places, not one. Spread across a full group that is £25 a head, below the cheapest standard ticket. It is a private session for a group, priced as a group.

What it involves is genuinely different: four guides, a pulley system, and a special wheelchair you transfer into, with help from a companion if you need it. You descend backwards. It runs up to 3 hours rather than 90 minutes.

The constraint is availability, not price. Wheelchair climbs run from late spring to early autumn, on weekday mornings only, and demand runs ahead of supply: “Due to high demand and popularity, we operate a waiting list which is processed on a first come first served basis.” Email the box office.

The chair’s published dimensions, which decide whether it will work for you: seat width 45cm, seat depth 40cm, frame width 70cm, frame height 99cm from floor to the top of the backrest.

Separately, for climbers who walk: “As a general rule, you can complete the climb if you can walk unaided.” A free carer ticket is provided where a climber needs a carer throughout, on evidence of an Access or Nimbus card with the +1 symbol plus a short explanation, sent to the box office in advance.

A weekday twilight climb costs less than a weekend daytime one

Six price points, and they do not line up the way you would guess. Checked on 6 October 2026:

Daytime, weekday: from £37.

Twilight, weekday: from £40.

Daytime, weekend: from £42.

Sunset, weekday: from £42.

Sunset, weekend: from £44.

Twilight, weekend: from £43.

Read that again. Twilight on a weekday, at £40, is cheaper than daytime at the weekend, at £42. You get the lit-up skyline, the multi-coloured roof lighting and the quieter slot, and you pay three pounds less than the people climbing in flat daylight on a Saturday.

The whole spread is only £7, from £37 to £44, so the time of day matters more than the money. If the money is tight, weekday daytime at £37 is the floor.

Between 6 November 2026 and 3 January 2027, every climb includes access to the Snow Globe Experience at the summit, with the standalone Snow Globe Climb listed from £44.

Fifteen minutes early, or not at all

Said as plainly as any venue in London says it.

“You must arrive 15 minutes before your climb time as latecomers cannot be admitted.”

Not the climb time: fifteen minutes before it. Base camp is near the main entrance of The O2, and you show your ticket at reception.

Two things to do before you travel. You must complete an online Declaration and Waiver form in advance. And drinks for the roof are bought on the day at reception, not carried up.

It climbs in almost any weather

More robust than most outdoor London attractions, and the exceptions are listed.

“Climbs will take place in all weather conditions other than gales, lightning, heavy snow or ice or extreme weather conditions which we reasonably believe will make it unsafe to climb. If we have to cancel a climb due to weather conditions we will rebook or refund your climb.”

So rain is not a cancellation. Gales, lightning and ice are, and a weather cancellation gets you a rebooking or your money back.

Dress for it. You are fitted with a harness and offered a jacket if required.

What you actually do

A 90-minute guided climb to 52 metres over the roof of The O2, with an expert guide throughout and all safety equipment included in the ticket.

At the summit there is a 360 degree view, and the venue’s own claim for a clear day: you can see landmarks up to 15 miles away. At night the roof’s multi-coloured lighting is part of the climb rather than something you look at from below.

Climbers must not be under the influence of alcohol or any legal or illegal substance. “You will not be permitted to participate and will not be refunded.”

For under-18s, the booking must include the correct number of adults for every climber aged 8 to 17.

Where it is

Up at The O2, Peninsula Square, London SE10 0DX. Box office 020 8463 2680.

North Greenwich is on the Jubilee line and directly outside. The IFS Cloud Cable Car lands on the peninsula, and Uber Boat by Thames Clippers stops at North Greenwich pier, which is the better arrival if you want to see the roof from the water first.

How to plan it

Check the measurements first: 21 stone, 125cm waist, 75cm upper thigh.

Minimum age 8, minimum height 1.2m. Not suitable if pregnant.

Best value for the view: twilight on a weekday, £40, cheaper than daytime at the weekend.

Cheapest: daytime on a weekday, £37.

Arrive 15 minutes early. Latecomers are refused.

Do the waiver online before you travel.

Wheelchair climb: £250 covers up to ten people, runs late spring to early autumn on weekday mornings, and has a waiting list. Email the box office.

Rain is fine. Gales, lightning and ice are not, and those get a refund or rebooking.

Questions we get asked

Is there a weight limit for Up at The O2?

Yes, and measurements as well. Climbers must not weigh more than 21 stone, 130kg or 286lbs, and the published maximums are a 125cm waist and a 75cm upper thigh. The limits come from the fixed safety harness, so there is no discretion at the door. Minimum age is 8 and minimum height is 1.2m, and the climb is not suitable for pregnant customers.

How much is Up at The O2?

From £37 for a weekday daytime climb, £40 weekday twilight, £42 weekday sunset or weekend daytime, £43 weekend twilight and £44 weekend sunset. The whole spread is only £7, and a weekday twilight climb is cheaper than a weekend daytime one, which makes it the best value for the lit-up view.

Can wheelchair users climb Up at The O2?

Yes, on a dedicated Wheelchair Climb. It runs from late spring to early autumn on weekday mornings, takes up to three hours and uses four guides with a pulley system, with the descent done backwards. The listed £250 covers one wheelchair user plus up to nine friends and family, carer free, so for a full group it works out cheaper per head than a standard ticket. Demand outstrips supply and there is a waiting list, so email the box office.

How long does Up at The O2 take?

The standard climb is 90 minutes, and you must arrive 15 minutes before your climb time because latecomers cannot be admitted. The Wheelchair Climb takes up to three hours.

Does Up at The O2 run in the rain?

Yes. Climbs take place in all weather other than gales, lightning, heavy snow or ice, or extreme conditions the venue judges unsafe. If a climb is cancelled for weather, it is rebooked or refunded. You are fitted with a harness and offered a jacket if you need one.
