How to Book a Babysitter in London Without a UK Phone Number

You have landed at Heathrow, the children are running on the wrong time zone, and you have a dinner reservation in two nights that you would rather not spend with a toddler under the table. So you search for a London babysitter — and the first three results ask you to download an app, create an account, and verify a UK mobile number you do not have.

This is the most common friction point visiting families hit. It is not a sign that London lacks good childcare; it is a sign that most of London's childcare platforms were built for people who live here. Here is how to work around it, and what to look for when you only have a few days.

Why Most London Babysitting Platforms Ask for a UK Number

Most UK babysitting services are app-first marketplaces designed around repeat local use: a parent in Clapham who needs a Thursday evening sitter every week, or a family looking for an ongoing after-school arrangement. That model relies on accounts, in-app messaging, saved payment methods and SMS verification — and SMS verification is where an international number often fails or arrives late.

Some platforms also carry membership or matching fees, and several place the responsibility for checking references on the parent. All of that is workable if you live here. On a five-night trip, it is a lot of admin for one evening out.

What Visiting Families Actually Need

Short-stay childcare is a different job from local childcare. From the enquiries we handle, visiting parents almost always want the same four things:

• Speed. An answer in hours, not a week of back-and-forth messages with individual sitters.
• Vetting done for you. No parent should be reference-checking strangers from a hotel room in a foreign city.
• Experience with children away from home. Jet lag, unfamiliar rooms, no favourite toys, a bedtime that has quietly moved five hours.
• No commitment. One evening. Possibly two. Not a weekly minimum.

How to Book Without an App, Account or UK Number

Step 1: Use an agency, not a marketplace

An agency handles the matching for you. You describe the evening once — dates, times, ages, where you are staying — and the agency proposes a sitter who is available and appropriate. A marketplace hands you a list and leaves the sifting, screening and chasing to you.

Step 2: Enquire in a browser

You do not need to install anything. Our availability form works in any browser on any phone or laptop, and there is no account, password or login involved. Give us your international mobile number if you want WhatsApp updates, or just an email address if you prefer.

Step 3: Confirm by email or WhatsApp

International numbers are standard for us, not an exception. Confirmation, sitter details and arrival instructions come by email or WhatsApp — nothing depends on you receiving a UK SMS.

Step 4: Tell us where you are staying

Hotel, serviced apartment or Airbnb, it matters. Many London hotels ask that childcare providers check in with the front desk or comply with in-room supervision policies, and we handle that with the concierge directly. If you are in an apartment or Airbnb, there is no concierge to lean on, which is precisely why an agency is useful.

Questions Worth Asking Any London Sitter Service

• Who vetted this person, and how? (Ours pass a six-step process including enhanced DBS checks, interviews and reference checks.)
• Are the sitters insured?
• Do they hold Paediatric First Aid?
• Will the same sitter cover both nights if we need two?
• What happens if our plans shift by an hour — is that a problem?

If a service cannot answer the first three quickly and clearly, keep looking.

A Note on Language

If English is not your children's first language, ask. Between them our sitters speak more than 30 languages, and for a nervous three-year-old in an unfamiliar hotel room, hearing their own language at bedtime does more than any amount of experience.

Frequently Asked Questions

Can I book a babysitter in London without a UK phone number?

Yes. We take enquiries with international mobile numbers and confirm by email or WhatsApp, so nothing depends on receiving a UK SMS. There is no phone verification step.

Do I need to download an app to book a babysitter in London?

No. Our enquiry form runs in any web browser. There is no app to install and nothing to keep on your phone after your trip.

Do I have to create an account or register?

No account, no password, no login. You send one enquiry with the details of the evening and we reply directly.

Is there a membership or subscription fee?

No. There is no joining fee, matching fee or subscription. Several UK babysitting platforms charge one; we do not.

Can I book for a single evening?

Yes. A single evening is our most common booking. There is no weekly minimum and no ongoing commitment.

How far in advance should I book?

As early as you can, especially for weekends, school holidays and December. That said, we regularly cover same-week and occasionally same-day requests, so it is always worth asking.

Are the babysitters vetted?

Every sitter completes our six-step vetting process, which includes identity verification, an enhanced DBS check, a face-to-face interview and reference checks. You never have to reference-check anyone yourself.

Can a babysitter come to my hotel room?

Yes, and it is what we do most. We work with concierge teams across London's hotels and follow each property's childcare policy. See our hotel babysitting page for how it works.

What about a serviced apartment or Airbnb?

Also covered. Without a concierge to arrange things, having one agency contact handling the booking matters even more.

Will the sitter know what to do with jet-lagged children?

Our sitters work with visiting families constantly, so unfamiliar rooms, shifted bedtimes and overtired children are routine. Many can also suggest daytime activities and attractions nearby.

The Short Version

You do not need a UK number, an app, an account or a subscription to find good childcare in London — you need a service built for people who are only here for a few days. That is the whole reason Stays exists for visiting families. Tell us the date, the times and your children's ages, and we will do the rest.
