BuildCert

Agentic building regulations compliance pack service for UK small builders and self-build homeowners undertaking notifiable works (extensions, loft conversions, structural alterations). It replaces the building control consultant or architect who manually drafts the building notice, structural calculations summary, thermal compliance evidence (SAP/U-value), and drainage layout documentation required for local authority or approved inspector sign-off. Delivers a submission-ready compliance pack in under 2 hours.

Why now

No live signals provided today; justified by persistent regulatory pain in UK construction — Building Safety Act 2022 secondary legislation tightening documentation requirements for all notifiable works, plus ongoing pressure on small builders from building control bodies requiring more structured evidence packs post-Grenfell reforms.

Commercial value

UK small builders (200,000+ sole traders and micro-firms) and self-builders face £800–£2,500 in consultant fees per project just to assemble building regs submissions. Each builder does 6–15 notifiable projects per year. SaaS pricing of £79–£149 per submission pack or £199/mo unlimited is credible. TAM: even 1% of ~500,000 annual notifiable domestic projects = £4–7M ARR at £149/submission.

Go-to-market

Target UK self-build and small builder Facebook groups, FMB (Federation of Master Builders) forums, and r/Construction UK threads. Offer first 10 customers a free pack in exchange for a testimonial. Price at £99/pack or £179/mo. Partner with one approved inspector body as a referral channel within 60 days.

2-week MVP

Single workflow: user inputs project type (e.g. single-storey rear extension), floor area, wall/roof construction spec, and postcode; LLM generates a building notice draft plus a U-value compliance summary table and a drainage strategy narrative — all in a single downloadable PDF. Cut: no structural calculations, no SAP full calculation, no drawing generation. Day-1 outcome: a builder submits the building notice to their local authority without paying an architect £400 to draft the covering documentation.

Agent score

0.64 — Commercial score reflects real, named budget line (architect/consultant drafting fees, £400–£800 per project) and large addressable builder population, but per-transaction pricing caps ACV unless builders subscribe. Speed is high — MVP is a form-to-PDF LLM pipeline shippable in under 2 weeks, and first 10 customers are reachable via FMB forums and Facebook groups without paid ads. Defensibility is weak at launch — a competitor could clone the form; moat only builds if proprietary local authority policy data and approved inspector partnerships are accumulated over 6+ months.
