“The Talipot House project was a challenge, with a tight budget, a high impact works program and demanding a high standard of finish. Sigma Electrical undertook the electrical works and did so in a thorough and professional manner. We had regular and positive contact with Sigma’s contracts manager throughout, and also with the electrical foreman on site, whose level of knowledge and pride in his work was evident. The project was completed on time and on budget, and achieved a great standard of finish ready for prospective tenants to view. Our experience of Sigma was very positive and we look forward to working with them again in the future.”
