We've used O'Brien Electrical Alexandria a few times now and our experience with them has been a pleasure each time. The assistance from Eloise and her prompt attention to my inquiries made booking the service very easy. Paul carried out each job with good knowledge and did exactly as instructed , he arrived on time and was always polite and friendly. I will use them again for any electrical work

Trudy C. -

The team at O’Brien Electrical Alexandria were prompt and professional from the get go. From Eloise in the office to Darren who attended they didn’t stop till the job was completed successfully. I didn’t know that this level of service still existed. I know who to call next time there is an issue. Prompt, professional and good value. Highly recommend.
