The Short Answer

Do children legally need a car seat in a taxi?

Not always — and this surprises most parents. Licensed taxis and private hire vehicles have a specific exemption in UK law: if the driver doesn't provide the correct child car seat, a child may travel without one, as long as they sit in the rear — children aged 3 and over must wear the adult seat belt, and children under 3 may legally travel unrestrained in the rear. The exemption exists for practicality, not because it's safe: an adult belt sits wrongly on a small body, and a lap is not a restraint. Our position is simple — the exemption should never need to be used. Request seats at booking and RushXO fits the correct infant carrier, child seat or booster free, in every vehicle class, at every London airport.

The Law, Plainly

UK child car seat rules — private car vs licensed taxi

In a private car, the rule is strict: a child must use an appropriate child car seat until they turn 12 or reach 135cm tall, whichever comes first. In a licensed taxi or private hire vehicle, the exemption below applies — worth knowing, so you can also judge any operator you ride with anywhere.

Child	Private car (the rule)	Licensed taxi/PHV (the exemption)	The RushXO standard
Under 3	Correct child seat, always — no exceptions	May travel unrestrained, rear seats only, if no seat provided	Infant carrier or child seat, fitted, free
3 to 11 (under 135cm)	Correct child seat or booster required	Adult seat belt, rear seats only, if no seat provided	Child seat or high-back booster, fitted, free
12+, or 135cm+	Adult seat belt	Adult seat belt	Adult seat belt — booster still available on request

Front seats are never part of the exemption — a child travelling without a correct seat must be in the rear. Newer seats sold in the UK follow the height-based i-Size (R129) standard, which also requires babies to travel rear-facing until at least 15 months; older weight-based R44 seats remain legal to use. This page is a plain-English summary, not legal advice — the definitive rules are on GOV.UK.

Which Seat?

Match the seat to the child — the 60-second guide

Seats are matched by height and weight, with age as the shortcut. When you book, give each child's age and — if you know them — weight or height, and dispatch stocks the car accordingly. If a child sits on a boundary, we bring both options and the driver fits whichever suits on the day.

0–15 months · to ~13kg

Infant carrier (rear-facing)

Rear-facing is non-negotiable for babies — it supports the head and neck, and under i-Size it's required until at least 15 months. Ours fits belt or ISOFIX; your own carrier off the flight fits just as well.

9 months–4 years · ~9–18kg

Forward-facing child seat

A five-point harness holds a toddler properly where an adult belt cannot. Fitted and tension-checked by the driver before the car sets off — not adjusted hopefully on a forecourt.

4–12 years · to ~135cm

High-back booster

Raises the child so the adult belt crosses shoulder and hips, not neck and stomach — with side wings for sleeping heads on the motorway. We stock high-back rather than backless boosters as standard, because they protect better.

On the boundaries: a tall 3-year-old may be better in a harnessed seat than an early booster; a small 5-year-old should stay harnessed longer. The height and weight limits win over the age label every time — mention any borderline child at booking and we'll bring both.

Yours or Ours?

Bring your own seat, or use ours? — the honest comparison

There's no single right answer — it depends on whether you need a seat at the destination. Both work with us: the driver fits whichever seat travels, yours or ours, before setting off.

Use ours when…

You don't need one abroad

Hire car with seats included, city trip on foot and transit, or visiting family with a seat waiting — travel light, carry nothing extra through security, and the same seats are waiting for the arrivals pickup on the way home.

Bring yours when…

You'll need it at the other end

Most airlines carry a car seat and a folded pram free for a child, checked at bag drop or, often, at the gate. Your own seat also means familiar fit abroad and no hire-car seat roulette. A padded travel bag protects it in the hold.

Either way…

The driver fits it

Belt-routed or ISOFIX, ours or yours — installed and checked before departure, not left to a bleary 4am parent on the driveway. Tell us at booking which seats are travelling and which are ours.

Flying with a toddler on your lap vs their own aircraft seat is the other half of this decision — many parents buy the child a seat and use an aircraft-approved car seat on board. Check your airline's rules for approved models; whichever you choose, the ground legs at both ends are covered here.

How It Works

From booking to buckled — four steps

Tell us the children, not just the count

Ages, plus weight or height if known, for each child — online, on WhatsApp or on 02088889988. "Two kids" books two belts; "a 1-year-old at 10kg and a 6-year-old" books the right seats.

Dispatch stocks the car

The correct carrier, seat or booster — ISOFIX where requested — is assigned with the vehicle. Borderline sizes get both options loaded.

Fitted before you see the car

Home pickup: seats installed before the car reaches your door. Arrivals pickup: installed before you land, so you walk from the name board to a ready car.

Repeated on the return

Your seat configuration is saved to the booking — the way home, weeks later, gets the identical setup without re-explaining anything from a departure lounge.

Seats fit every vehicle class — saloon, estate, MPV, V-Class and 8-seater — without reducing stated luggage capacity. Three or more seats? See the FAQ below on three-across.

Why RushXO

Why the seats are free — and why that's rare

Most operators treat child seats as an upsell, an "on request, subject to availability" footnote, or someone else's problem under the exemption. We treat them as part of carrying a family properly — the same way the luggage help and the name board are.

TfL licensed, licence 11588

A Transport for London Private Hire Operator with directly contracted drivers — the seat policy is company standard, not driver's choice.

No seat charges, ever

No per-seat fee, no "premium family vehicle" markup — the fixed fare for the route is the fare, with the seats in it.

Every airport, both directions

Gatwick, Heathrow, Stansted, Luton and London City — departures from home and arrivals meet-and-greet, same policy everywhere.

Driver-fitted, always

Installation is the driver's job and checked before departure — parents supervise, they don't wrestle.

i-Size aware stock

Rear-facing carriers for the under-15-month rule, harnessed seats, high-back boosters — matched to current standards, not a dusty one-size booster in the boot.

FAQ

Child seats & taxis — what parents ask

Can a child travel in a taxi without a car seat?

Legally, yes — under the licensed taxi/PHV exemption, if no correct seat is provided: rear seats only, with the adult belt from age 3, and under-3s may ride unrestrained in the rear. Legal is not the same as safe, which is why our seats are free — the exemption should never need using.

Can my baby sit on my lap?

In the rear of a licensed taxi it's within the exemption for an under-3 — and strongly discouraged. In any sudden stop an adult cannot hold onto a child. Request an infant carrier at booking; it costs nothing and it's fitted before pickup.

Do the seats cost extra?

No — every seat type, in every vehicle class, at every airport, free. Your fixed fare doesn't change because children are travelling properly.

Do you have ISOFIX?

Our MPVs, V-Class and most saloons have rear ISOFIX points, and we stock both ISOFIX and belt-fitted seats. If ISOFIX is essential — for your own base, say — mention it at booking and dispatch assigns a confirmed-ISOFIX vehicle.

Can you fit three child seats in one row?

Rarely in a saloon — three full seats seldom fit a standard bench. Three or more children in seats means an MPV, V-Class or 8-seater, where each seat gets a full-size position. Tell us all the ages and we assign the right vehicle.

How long should my child stay rear-facing?

Until at least 15 months under the i-Size standard — and longer is better where the seat's height/weight limits allow, as rear-facing protects the head and neck best. Our infant carriers are rear-facing; tell us your preference for a child near the boundary.

Can I use my own car seat in your taxi?

Yes — the driver fits it, belt-routed or ISOFIX, before setting off. Common on airport runs when the seat is flying with you: most airlines carry a car seat and folded pram free for a child.

Backless booster cushions — do you use them?

We stock high-back boosters as standard because they position the belt better and protect the head and torso in side impacts. Backless cushions remain legal for older/taller children, but high-back is what goes in the car unless you ask otherwise.

Does this apply at Heathrow and the other airports too?

Identically — Gatwick, Heathrow, Stansted, Luton and London City, both directions. Start from the Gatwick family pickups page, the taxi to Gatwick with kids page, or any airport hub.
