Purchase Report

Industry Summary

The 81,842 Electrical contractor firms in the US provide electrical installation, repair, and maintenance work. They handle wiring, lighting, networking, fire and safety equipment, and energy management systems, among other tasks. Much of the work is installation and repair of residential electrical wiring. Contractors must buy materials and then install them according to code in homes and other buildings.

Liability for Damages

Oftentimes builders or general contractors will try to cut corners, directing ECs to take shortcuts that violate code.

Demand Dependent on Construction Activity

Contractors can market new services such as design work during periods of low demand, but new construction ultimately drives the industry.


Recent Developments

Jul 9, 2025 - US Construction Spending Drops
  • The total value of construction put in place declined 0.3% in May 2025 compared to April, according to the US Census Bureau. Spending on nonresidential projects decreased 0.2% and residential spending was down 0.5%. Within the nonresidential building construction segment, lodging saw the most significant drop in May as spending fell 1.4%, followed by commercial (down 0.8%) and office (-0.2%). However, pockets of nonresidential building construction growth in May included public safety (up 0.7% over April), amusement and recreation (+0.5%), communication (+0.4%), healthcare (+0.4%), transportation (+0.2%), and healthcare (+0.1%). High mortgage rates and rising numbers of unsold new homes have weighed on the new single-family housing market, according to Reuters. US trade policy has also contributed to increased economic uncertainty.
  • New single-family home sales fell 13.7% month-over-month and were down 6.3% year-over-year in May 2025, according to the US Census Bureau. May’s total new home sales reached 623,000 units. According to Dow Jones estimates, Wall Street analysts had expected May sales to reach 695,000. In recent quarterly reports, some homebuilders said high interest rates and weaker consumer confidence weighed on demand. As sales of new homes remain soft, inventories of unsold homes are increasing. At the end of May, there were 507,000 new homes for sale, up 15% compared to May 2024. The number of unsold new homes in May was the highest since the summer of 2022, after the Federal Reserve began increasing interest rates.
  • Demand for data center construction remains steady, according to Construction Dive. Between March 2024 and March 2025, data centers accounted for more than 70% of spending growth in the nonresidential construction sector. According to real estate services firm CBRE, primary data center hub locations include northern Virginia, Atlanta, Chicago, and Phoenix, but developers are branching out to new geographic locations amid recent trends in onsite electricity generation and dedicated substations for data center electricity needs. While contractors are mostly optimistic about data center growth, challenges include long lead times for equipment (such as transformers, switchgear, and uninterruptible power supplies), adequate power access, labor shortages, and rising materials costs. Contractors with expertise in preconstruction services – including site condition evaluation, utility interconnection timelines, and entitlement risks – are in strong demand.
  • Some home-services firms are leveraging AI-enabled tools to increase the accuracy and efficiency of scheduling, customer service, and other operations, according to The Wall Street Journal. One startup, Netic, offers AI-enabled software that can answer and return customer calls, predict maintenance needs based on weather or emergencies, and schedule and prioritize work orders. AI adoption in the home-services trades is being led by private equity firms active in roll-up consolidation in fragmented services industries, including electrical, plumbing, roofing, and HVAC. Integrating AI, which is often compatible with customer relationship management software, can help private equity firms manage their portfolios of home-services firms, boosting efficiency and profits. Large, independent home-services firms are also investing in AI.
