Common questions about BuildFlo
Straight answers on UK MEP AI, Building Regulations, calculators, fee proposals, data, and early access - so you know exactly what you're joining.
BuildFlo is an AI workspace for UK building services (MEP) design consultants. It helps you ask regulation questions with sources, size systems, check drawings, write fee proposals, and run project delivery in one place - instead of hunting Approved Documents, spreadsheets, and email.
Yes. BuildFlo is built for UK M&E and MEP design engineers and consultancies - from graduates through seniors, principals, associates, design managers, and coordinators. Domain language is UK-first: Part F, Part L, Part O, BSRIA, British Standards, RIBA stages, and public health / mechanical / electrical practice.
General AI guesses. BuildFlo checks. Answers are designed around indexed UK building services standards - including Approved Document Part F, Part L, and British Standards - with clause-style citations so you can verify before you rely on them. Everyday sizing uses a deterministic UK calculation engine, not LLM arithmetic. It is also designed to say when it does not know, rather than invent a confident reply.
Coverage includes UK Building Regulations guidance such as Approved Document Part F (ventilation) and Part L (conservation of fuel and power), relevant British Standards, and BSRIA publications used in building services design. Indexed coverage expands with each release.
BuildFlo includes UK MEP calculators for everyday sizing checks - including pipe sizing, duct sizing, U-values, lux levels, voltage drop, MVHR sizing, drainage, cold and hot water storage, flue sizing, kitchen canopy extract, and more - grounded in British Standards and Approved Documents where applicable. Results can be saved to the project.
Yes. Fee proposals turn an enquiry pack into scoped stages, fees, and exclusions for a client-ready Word proposal - this feature is limited release and may need access granted first. Project tools cover todos and Gantt, meeting minutes, info release, drawing issue sheets, handover, equipment schedules, and related delivery work. Feasibility study is also limited release. Outlook automations can help with enquiry triage.
BuildFlo is free during early access. Join the waitlist or create an account on this page, then create a project and start with chat, a calculator, or drawing QA. Personal and Business paths are available; Business can book a call for a personalised quote. Some features such as fee proposals and feasibility study may require an access grant.
Projects, chats, and uploads stay with you and are not used to train models. See the Privacy, Terms, Data Handling, and Data Processing pages for how account data is handled, including export and deletion. Team roles include owner, admin, and member. For Business procurement conversations, book a call.
No. BuildFlo is a specialist design companion, not a replacement for professional judgement. Always verify critical compliance decisions against the project specification and the cited standard before issuing calculations or advice.
