Hi
I will be hiring someone via one of the find-a-builder type websites to replace a broken electric shower with exactly the same model but lower power (9.5 Kw ->8.5 Kw).
What should I ask for in terms of certifications etc if any? I am more worried about the electric part of the installation. Also, is hand written receipt on completion sufficient to prove the facts should anything go wrong later ?
Thanks
