SubmeterTech is owned and operated by Matt Lasswell, a respected industry professional with more than 25 years of hands‑on experience in submetering systems of all kinds. 

We install new systems into new construction, service, and system correction.  

After spending his career working for one of the original pioneers of the submetering industry 25 years ago, Matt stepped forward when the owner retired  in 2025 — purchasing the trucks, equipment, and infrastructure needed to continue serving the growing demand for high‑quality submetering work and starting his own company. 

Matt recognized a clear need in the market for apartment managers, 

Developers, Billing companies, and Manufactures. 

He can make recommendations too. 

 He can help YOU as well:

• New construction submetering installations done correctly the first time.

• 
  

• Fixing poor or incomplete New Construction installations left behind by untrained contractors.

• 
  

• Servicing Billing Companies and programming and troubleshooting for cloud‑based billing platforms

• 
  

• Servicing Property and Apartment Management Companies

• 
  

• Working for National water metering Vendors to trouble shoot local concerns. 

• 
  

The time line of knowledge. 

Drawing on decades of field experience, Matt has led multiple installation crews simultaneously, managed purchasing operations, worked with BWM successfully,  and resolved complex cloud‑based billing issues for private utility billing companies across the whole state. He also carries forward a specialized alignment and correction technique taught directly by his former mentor— the same individual who introduced and installed the first hard‑wired submetering systems in California in the late 1980s.

While no company can claim to know everything, you would be hard‑pressed to find a team more dedicated, better trained, or more committed to doing the job correctly. Submetertech approaches every project with precision, integrity, and a deep understanding of how these systems are meant to function.

Today, Submetertech continues that legacy of precision and craftsmanship. Matt and his team are among the best‑trained technicians in the industry, known for their accuracy, reliability, and commitment to doing the job right.
