Yes, provided the childcarer is officially recognised - either "registered" or "approved".

What does "registered" or "approved" mean?

This means that the childcare must be provided by one of the following

a childcare provider approved under a Ministry of Defence accreditation scheme abroad
an approved foster carer (but the care must be for a child who is not a foster carer's foster child)
a childcare provider registered by Ofsted
if registered by Ofsted, a school in school hours for a child not yet of compulsory school age, ie until 31 August following the child's fifth birthday
out-of-school-hours childcare or supervised activity based childcare, provided by a school on the school premises, or by a local authority, or by a childcare provider registered by Ofsted
a person approved under the Childcare Approval Scheme providing childcare in the child's home or in other domestic premises
a domiciliary worker or nurse from an agency registered under the Domiciliary Care Agencies Regulations 2002 and providing childcare in the child's home.

Childcare provided by a relative

Qualifying childcare does not include care provided by a relative of the child in the child's own home. This includes relatives who are registered or approved childcare providers. For these purposes a relative means

parent
step parent
foster parent
grandparent
aunt or uncle
brother or sister

whether by blood, half blood, marriage or civil partnership. In the case of foster parents this means a foster parent appointed by a local authority or voluntary organisation, or a person who fosters the child privately within the provisions of section 66 of the Children Act 1989.

Childcare provided by relatives can be qualifying childcare in the following circumstances

the relative is a 'registered' or 'approved' childcare provider, and
the care is provided away from the child's own home, and
the care is provided to non-related children in addition to the related child or children.

If not registered or approved, what can my carer do?

“Registered” means registered with Ofsted. It is possible, although very unlikely, that a nursery is not registered with Ofsted – but you can check by going to www.ofsted.gov.uk and keying in the name or postcode of the carer or telephoning Ofsted on 0845 601 4771.
“Approval” is required before vouchers can be used in part payment of the fees of a childminder not required to register with Ofsted or the salary of a nanny or au pair. On her or his behalf you can obtain information from www.childcareapprovalscheme.co.uk Or telephone Nestor Primecare Services on 0845 7678 111.
