TSI is a family owned and run business based in Truro, Cornwall. Over the last decade we have grown to provide full M & E installation, plumbing and heating services and full construction services across the South West from Bristol to Penzance.

We always work closely with our clients, contractors and specialist suppliers to provide the best quality possible and can reduce your carbon footprint and running costs with the full range of low energy and renewable resource technologies. From an individual bespoke construction project to a 100-unit development, our team of experienced, fully trained and accredited electricians, plumbers and fitters are proud to get the job done effeciently and professionally.

Working with your architect or designer we can aid project management with advice and source materials, provide installation schematics and as-built plans to bring the project in on time, on budget and to the highest quality.

In addition to consultation and installation, we offer aftercare maintenance and servicing. For domestic customers, we can also help with energy surveys and financing.

Being in the building trade for the last 20 years we have a wealth of knowledge across the board and work with some very talented individuals. We wanted to bring the whole project under one roof and deliver excellence and peace of mind for our clients.
