More about Petra

A need for self-direction in Petra’s life meant a quick turnaround in jobs including cleaning, auxiliary nursing (Croatia) caretaker (Croatia) war interpreter (Croatia) bar-maid, shop assistant, childminder, full time carer for a cancer patient, mother, daughter.

Finally finding a passion as a plumber and the combined control and flexibility of self-employment.

Petra joined Stopcocks to become our Woman Plumber in Balham in 2011 and completed her City and Guilds and Level 2 NVQ before the rest of her colleagues in college following that up by completing her NVQ 3.

She completed her Gas Safe Certification in September 2015 and next plans to train in sustainable energy.
