Section 52 | Service to be performed within a reasonable time
From legislation.gov.uk
(1)This section applies to a contract to supply a service, if—
(a)the contract does not expressly fix the time for the service to be performed, and does not say how it is to be fixed, and
(b)information that is to be treated under as included in the contract does not fix the time either.
(2)In that case the contract is to be treated as including a term that the trader must perform the service within a reasonable time.
(3)What is a reasonable time is a question of fact.
(4)See for a consumer's rights if the trader is in breach of a term that this section requires to be treated as included in a contract.
