BPI describes the BA-P as a certified Building Analyst Technician who also conducts energy modelling. The technician proved they can take the measurements; the professional proves they can turn them into a prioritised work scope.
The BA-T asks whether you can operate a blower door and a combustion analyser correctly. The BA-P asks what you do with the numbers afterwards — and it is the half that separates a technician from somebody a homeowner should take advice from.
“A Building Analyst Professional is a certified Building Analyst Technician who also conducts energy modeling” and related building analysis and data evaluation, producing a report with prioritised home performance recommendations.
So the deliverable BPI is certifying is a report: findings, a model, and a ranked list of what to do first. Not a test result.
BPI’s handbook does not state a question count, and we are not going to invent one. Ask and we will tell you what BPI confirms to us rather than what a competitor’s blog says.
BPI lists one prerequisite: an active BPI Building Analyst Technician certification. Which in turn requires Building Science Principles. Three credentials, in order, and the field exam is in the middle.
Because the BA-T is a prerequisite rather than a historical step, BPI deactivates the BA-P if the BA-T expires. You can hold a current BA-P, forget the BA-T renewal underneath it, and lose both. Renewal windows open six months before expiry on each. Put both dates in the same diary entry.
Three-year term. Hold an active BA-P and then either:
Thirty units over three years is ten a year, and CEUs are generally awarded at one unit per training hour. That is a manageable annual habit and considerably less unpleasant than re-sitting a two-and-a-half hour exam. How continuing education works →
Nor is anyone’s. BPI does not require training before this exam, and does not approve, accredit, endorse or recognise training from any provider — it says so in its own brand policy. We teach preparation for the BA-P and we would rather you bought it because it is good than because of a badge that does not exist.
Scope, prerequisite, exam format, two-and-a-half hour limit, 70% pass mark, domain weighting, both renewal routes and the BA-T deactivation rule: BPI Building Analyst Professional Scheme Handbook, revised 1 January 2023. Attempt limits, identification, proctoring and recording: BPI Core Certification Scheme Handbook, revised 9 April 2026. Term and the 30-CEU figure: BPI certifications list, updated 27 April 2026. Checked against BPI’s published documents on 21 October 2026.
BPI’s BA-P handbook carries a revision date of 1 January 2023, older than the other documents cited in this section. Read the current handbook before you book, and tell us if anything here no longer matches.
Yes. BPI lists an active Building Analyst Technician certification as the prerequisite, and BA-T itself requires the Building Science Principles certificate. Three steps, in order.
No. The BA-P is a proctored multiple-choice exam. The field work is the BA-T, which sits underneath it.
Two domains: Analysing Collected Data at 64%, and Modelling and Work Scope at 36%. Two thirds of it is interpretation rather than software.
BPI's handbook does not say, and we are not going to guess at a number for you. Ask and we will tell you what BPI confirms.
Yes. Thirty whole-house building science related CEUs across the three years, plus the renewal application. That is roughly ten training hours a year.
BPI deactivates the BA-P as well, because the BA-T is a live prerequisite rather than a completed step. Track both expiry dates together.
No. The current chain is BA-T then BA-P. If a programme document or client contract names a plain “Building Analyst”, confirm with the issuer which credential they mean before buying an exam.
