What TSI Scotland does
TSI Scotland Ltd is a private, Milngavie-based energy and environmental compliance consultancy founded in 2002 that serves organisations operating within Scotland. The firm provides a portfolio of professional advisory services centered on energy auditing, continuous energy logging, environmental compliance and permitting, Renewable Heat Incentive (RHI) applications, ESOS compliance, Carbon Neutral planning, and Streamlined Energy and Carbon Reporting (SECR). Its stated value proposition is to help clients operate economically while remaining within UK and Scottish environmental and energy regulations, often acting as a regulatory liaison with authorities on the client's behalf. The underlying technology is professional services expertise rather than a software product; there is no app, no API, no disclosed proprietary platform, and no AI/ML components referenced. Core offerings are delivered through systematic assessment of energy consumption patterns, continuous monitoring of usage data, and strategic planning for carbon reduction and regulatory adherence.
The firm operates as a B2B professional services business on a project-based, quote-based engagement model, with no publicly disclosed pricing or contract values. Its go-to-market is direct enterprise field sales within Scotland, supported by a minimal marketing footprint consisting of a company website and an Instagram profile; client acquisition appears to rely primarily on referrals, professional networks, and direct business development within the Scottish commercial sector. TSI Scotland is founder-led by Managing Director Colin Porteous, whose direct contact details are listed on the company website, and operates with a headcount of 1-10 employees. The firm holds no disclosed patents, trademarks, certifications, partnerships, funding rounds, or M&A activity, and is entirely Scotland-domiciled with no claim to international operations.

Company assessmentBroad incumbents
- DNV: Independent assurance and certification provider with growing climate and energy services — directly comparable on energy auditing, ESOS assessments, and carbon/ESG assurance for UK corporates.
- Energy Savings Trust: UK-wide charity advising organisations on energy efficiency, low-carbon technology and related regulatory compliance — comparable energy advisory positioning though operating at broader national scale.
- Ricardo plc: Global environmental and energy consultancy offering energy auditing, ESOS compliance, and sustainability advisory — overlaps with TSI's core services but at much larger scale and international scope.
- Carbon Trust: UK-headquartered advisory organisation providing carbon footprinting, SECR support, and decarbonisation advisory to businesses — directly comparable service lines but at significantly larger scale and broader geographic reach than TSI Scotland.
- SLR Consulting: Global environmental and energy consultancy offering environmental permitting, ESOS compliance, and energy advisory — comparable to TSI's compliance-and-permitting service line but at larger scale.
- Bureau Veritas: Testing, inspection and certification major with an expanding ESG and energy compliance practice — provides ESOS assessments, ISO 14001 certification and SECR-related assurance comparable to TSI's compliance services.
- WSP Environment & Energy: Global professional services firm with a dedicated environment and energy advisory practice covering ESOS, SECR, permitting, and carbon strategy — competes for the same client mandates as TSI Scotland at multi-national scale.

- EcoAct: International carbon consultancy (now part of Atos) providing carbon accounting, SECR reporting, and net-zero strategy — directly comparable offering to TSI's carbon reporting and carbon neutral planning services.
