Reviewed against Approved Document B (gov.uk), the Equality Act 2010 (legislation.gov.uk), and the Regulatory Reform (Fire Safety) Order 2005 to the best of our knowledge at the time of writing. UK building regulations and venue safety rules vary by occupancy and venue, so always check Approved Document B and your venue's risk assessment for your specific event.
Stalls, Circle, Side, Standing
Once a venue gets past about forty seats, a single block of seating becomes hard for buyers to read. Break the room into named sections and treat each as its own mini-plan. Standard UK names work well because audiences already understand them: Stalls for the main floor, Circle for any raised tier, Side for the wings, Balcony for the upper level, Standing for any standing area. Sections also let you price differently: front Stalls higher than back Stalls, Side discounted because of partial sightlines.
Letters for rows, numbers for seats
UK theatres traditionally use letters for rows and numbers for seats. Row A is nearest the stage and seats are numbered consecutively across each row. Two common approaches: continuous numbering across the whole house (1 to 200, left to right, regardless of section) or per-section numbering (Stalls A1 to A20, Circle A1 to A20). Per-section is far easier for audiences to navigate in a multi-tier venue. Continuous works in single-block halls. Pick one, apply it consistently, and never start numbering from the right in one row and the left in the next.
Numbers run across the whole venue (1-200). Works for single-block halls without sections.
Each section restarts at A1 (Stalls A1, Circle A1). Easier for audiences in multi-tier venues.
Always number rows from the same side. Never alternate. Never skip numbers (no row 13 confusion is not worth the chaos).
Be honest about what each seat can see
Pillars, sound desks, lighting rigs, and railings hide parts of the stage from some seats. Walk every row before you publish the plan and sit in the seats that look suspect. If a seat genuinely cannot see all of the playing area, mark it as restricted view, discount it, and say so plainly in the listing. Buyers respect honesty and resent surprises. The worst thing you can do is sell a seat behind a pillar at full price and let the customer find out at the interval. They will not come back, and they will tell everyone they know.
Approved Document B and your venue's risk assessment
Fire safety, escape routes, gangways, row lengths and capacity should be checked against the current Approved Document B (the statutory guidance to the Building Regulations on fire safety for buildings other than dwellings, Volume 2), your venue licence, and your local authority or fire officer's advice. The exact figures depend on capacity, layout, and the distance to the nearest exit, and they are revised periodically. Do not rely on a ticketing seating plan as a compliance document, and do not hard-code a number you read on a blog. The Regulatory Reform (Fire Safety) Order 2005 places a duty on the responsible person for the premises to carry out a suitable and sufficient assessment of the risks (Article 9), and requires that emergency routes and exits are kept clear, sized for the maximum number of people present, and lead as directly as possible to safety (Article 14). Larger venues, raked seating, and licensed premises have stricter requirements. If in doubt, your local fire officer would much rather answer a polite question in advance than write a report afterwards.
Equality Act 2010 reasonable adjustments
Designate explicit wheelchair spaces on the plan (typically at the end of rows nearest accessible entrances, with step-free routes from the door) and place at least one companion seat directly next to each. Do not bury accessibility in the plan and hope nobody asks. Under the Equality Act 2010, a venue or event organiser providing a service to the public is a service-provider for the purposes of Section 29, and Section 20 imposes a duty to make reasonable adjustments where a provision, criterion or practice (or a physical feature) puts a disabled person at a substantial disadvantage. Pre-allocating accessible spaces is the bare minimum. Price them sensibly (the same as adjacent seats, never more), make them easy to spot on the public plan, and brief your front-of-house team so they are not improvising on the night. If you wait until the plan is published to think about accessibility, you will find it almost impossible to insert a wheelchair space later without renumbering whole rows.
End of rows, near accessible entrances, with step-free access from the door. Reserved on the plan, not improvised.
At least one directly next to each wheelchair space. Travels with the accessible booking.
Aisle seats near exits for assistance dogs, hearing loop coverage, seats with extra legroom for limited mobility.

Comp tickets, accessibility, last-minute fixes
Always keep some seats unsold. You will need them for last-minute accessibility requests that did not come through booking, complimentary tickets for press, governors, sponsors, the building owner and the cast's families, group bookings that arrive late, and the inevitable booking error that needs fixing without bumping a paying customer. For most events, five to ten per cent of the house held back works well. You can always release held seats a day or two before the show if demand is strong. What you cannot do is conjure them up once they are sold.
Mock bookings, phone checks, fresh eyes
Before you make the plan live, run a full mock booking from start to finish. Pick seats, get to checkout, look at the confirmation email. Sit in a few different seats yourself (the front row, the corner of row K, the restricted-view seat) and check the description matches the experience. Then ask a friend who has never seen the plan to navigate it without help: if they hesitate, the plan is not clear enough. Finally, do all of it again on a phone. If the booking flow is awkward on a small screen, fix it before launch, not after.
