Called me ten minutes after placing the request. Daniel immediately arranged to do the job the next morning and gave me a cost at the same time. He called me twenty minutes prior to his arrival. When he arrived, we discussed the work in more detail and he completed everything very quickly and neatly. Provided a test certificate as requested. He was a very pleasant and professional. This is what I expect from a company who is registered as a NIC EIC electrician and would recommend others to do the same.

In a nutshell, Marius and his team are great. They're kind, respectful and Marius is always available to answer every question you have - he def is the most knowledgeable builder I've spoken to. You get a very transparent estimate and sign a contract, for both parties' peace of mind. If extras come up, Marius openly discuss them with you before taking any action - my job required quite a few and Marius was also great to stay competitive price-wise whilst keeping the quality of the work sky-high.
