What It Is

MEPCalc is an online calculation SaaS for mechanical, electrical, and plumbing engineering (MEP), positioned around “replacing spreadsheets with traceable calculations.” It covers engineering calculations such as cable sizing, duct sizing, HVAC loads, pipe sizing, drainage, and refrigeration, while emphasizing that every result can be linked back to standards including BS 7671, CIBSE, ASHRAE, BS EN, ISO, and Approved Docs.

Core Features and Standards Traceability

Based on the examples shown on the page, MEPCalc does more than output a single number: it presents calculation results, compliance checks, and supporting references. For example, cable sizing shows the selected cable size, current-carrying capacity, required current rating, current check, voltage drop check, and cites BS 7671 Table 4E2A. This is useful for engineering review, internal verification, and reducing disputes—especially for teams that have historically relied on multiple versions of Excel files.

Pricing and Trial

The page offers a 7-day free trial with no credit card required, which lowers the barrier to initial evaluation. However, the captured page content does not disclose specific plan pricing, user limits, enterprise features, or billing cycles. The page also includes “Join the waitlist,” suggesting the product may still be in waitlist access or being rolled out in phases.

Collaboration, Security, and Integrations

The current page content does not mention third-party integrations, team collaboration, permission controls, audit logs, data security compliance, APIs, or developer support. As such, it currently looks more like a specialist calculation tool than a full engineering collaboration platform. For company-wide standardization, teams should further verify its data storage, permissions, export options, version management, and compliance capabilities.

Pros, Cons, and Who It’s For

Its strengths are a focused use case, clear coverage of professional standards, and the ability to solve the “multiple answers from messy spreadsheet versions” problem. Its main weakness is the lack of public information, especially around pricing, enterprise administration, and the integration ecosystem. It is suitable for building services consultants, MEP design engineers, and electrical/HVAC/plumbing/drainage/refrigeration professionals to trial and evaluate.

Access from China

Access from China is unknown, and payment methods are not disclosed. If a team plans to use it from mainland China, they should first test site connectivity, the registration process, and payment feasibility. Alternatives may include internal standardized Excel templates, local MEP calculation software, or engineering calculation tools integrated with BIM/design workflows.
