Envirotect

What Envirotect does

Envirotect Limited is a UK-based specialist manufacturer of structural radiation and RF shielding solutions, founded in 2000 by Niven Smith and headquartered in Leighton Buzzard, Bedfordshire. The company designs, fabricates, and installs custom lead-lined and copper-based shielding products for diagnostic imaging environments, primarily serving the healthcare sector (MRI suites, CT, and x-ray rooms) alongside veterinary, dental, security, research, and chiropractic end markets. Its core portfolio splits into two product lines: MR & RF shielding (RF cages, MRI-compatible enviro-Bright LED lighting, enviro-View decorative picture lighting, RF doors, enviro-Steel magnetic steel shielding, filters and waveguides) and x-ray shielding (lead-lined door sets, viewing windows, panels, lead glass, x-ray screens, lead vinyl variants, and shielded cabinets). Underlying technology combines high-pressure bonded lead composites, electrically deposited copper Faraday cages, magnetic steel for 5 Gauss containment, and specialised LED drivers tolerant of MRI magnetic fields, all manufactured to Radiation Protection Advisor specifications under ISO 9001:2015 and ISO 14001:2015 quality systems.

The business operates a project-based, quote-driven revenue model: products are custom-manufactured to individual site specifications, with pricing determined by lead code (3 through 8, equivalent to 1.32mm–3.55mm lead thickness), size, finish, and installation requirements. Revenue streams comprise one-time product sales and recurring professional services including RF cage installation, independent RF attenuation testing, annual RF door servicing (including third-party ETS-Lindgren doors), steel shielding calculations using finite element analysis, and EMI/vibration surveys. The go-to-market is sales-led and event-driven, relying on direct quote requests via the company website and telephone, supplemented by active participation in healthcare sector exhibitions (Healthcare Estates and UKIO). Distribution is direct B2B with the company's own trained installation team delivering and commissioning products at customer sites across the UK and selectively internationally.
