Travelling with children in Britain

Fares and rules change. Figures below are as the official pages stated on 25 Oct 2026; check the page, or your train company, before you travel. This is general information, not legal advice.

Trains and buses

• Under 5. National Rail says children under 5 can travel free on most journeys, but to check with your train company. They may only occupy a seat that a fare-paying passenger does not need; for a reserved seat you need a child ticket.¹
• Ages 5 to 15. National Rail says they get a 50% discount on most tickets. Child tickets include seat reservations where available, and the Child Rate Photocard is free at any staffed National Rail station.¹
• Family & Friends Railcard. The Railcard site says it gives one third off adult tickets and up to 60% off child tickets (ages 5 to 15), under-5s travel free, up to 4 adults and 4 children can use one card, and at least one named adult and one child must travel together. On 25 Oct 2026 it listed £35 for one year and £80 for three years.² Check its terms for exclusions.
• London. TfL says a fare-paying adult can travel with up to 4 children under 11 free of charge, and that children do not need a 5-10 Zip Oyster photocard on buses and trams.³ Our Family London guide has buggy advice and family days out, and our transport page has the journey planner.
• Other operators. Buses, trams and coaches outside London set their own child fares and ages. We did not fetch those pages, so we state nothing: check the operator. See getting between regions for official links.

Car seats

GOV.UK says children generally need a child car seat until they are 12 years old or 135cm tall, whichever comes first, and must then wear a seat belt. For height-based seats, children must ride rear-facing until they are over 15 months old. Only seats approved under the R129 or R44 standards (marked with an E in a circle) can be used in the UK, and front airbags must be deactivated before a rear-facing baby seat goes in a front seat.⁴ The page we read does not cover taxis, so ask the taxi firm or check GOV.UK. If you are hiring a car, ask the hire company what seats it supplies.

Family-friendly areas by destination

This table counts places carrying a family-friendly flag in our data: a family tag on a place to eat or stay, or, in London, a place on our family list. A flag is our editorial label from the place’s own information, not an inspection. It shows where we hold family information, not that other areas are unsuitable.

We hold no family-friendly flags yet for Aberdeen and Aberdeenshire, Bath, Blackpool and the Lancashire coast, Brighton & Hove, Cambridge, Canterbury & Kent, Cardiff, Cornwall, Coventry, Edinburgh, Glasgow, Gloucester, Hereford, Ironbridge Gorge, Leeds, Leicester, Lincoln, Lindisfarne (Holy Island), Llangollen and Pontcysyllte, Newcastle and Gateshead, North Coast 500, Northern Ireland, Nottingham, Orkney, Oxford, Portsmouth and Southampton, Salisbury & Stonehenge, Sheffield, Shetland, Shrewsbury, St Andrews and Fife, Stratford & Warwickshire, The Cotswolds, The New Forest, The Outer Hebrides, The South Downs, Worcester, York, Yorkshire.

Where to stay

Our where to stay pages compare areas for families using these flags, walking cues in the area text and the number of things to do. Ask the property about family rooms, cots and child policies before you book. See also accessible travel for step-free and sensory-friendly resources, and travelling with pets.
