Cert-ain Certification Ltd. is a UKAS accredited certification body serving the UK building services engineering industry. 

We are responsible for developing a range of assessments and training courses from nationally agreed criteria and for approving assessment centres to deliver them. 

Operatives successfully completing our assessments are promptly issued with a recognised Cert-ain Certification Ltd. certificate of competence/achievement. Where appropriate, we will also upload the certification details to the relevant industry registration body e.g. Gas Safe Register or OFTEC.
