How fast is bim.ie?
We run Lighthouse CI on every deploy and publish the results here. Scores are measured on a mobile profile with emulated network throttling — the hardest meaningful test of real-world page performance.
Headline scores
97/100
Minimum Lighthouse Performance score
across all sampled page templates.
100/100
Minimum Lighthouse Accessibility score
across all sampled page templates.
Homepage Performance improved from 91 to 98/100 over 12 weeks of optimisation
Latest Lighthouse scores — week of 2026-05-10
Four page templates are sampled each week: the Homepage, Funding Finder list, Funding Scheme detail, and Training Catalogue list. Each score is the median of three Lighthouse runs to reduce noise from emulated throttling variance.
| Page | Performance | Accessibility | Best Practices | SEO |
|---|---|---|---|---|
| Homepage | 98 | 100 | 100 | 100 |
| Funding Finder list | 97 | 100 | 100 | 100 |
| Funding Scheme detail | 97 | 100 | 100 | 100 |
| Training Catalogue list | 97 | 100 | 100 | 100 |
Scores: 95+ = excellent · 80–94 = good · <80 = needs improvement
How we measure
- Tool: Lighthouse CI
(LHCI) running in GitHub Actions on every push to
main. - Device profile: Emulated Motorola G4 (mobile) — 1x CPU throttle, 150ms RTT, 1.6 Mbps download, 750 Kbps upload.
- Sampling: Three runs per page; the median score is recorded. Results stored as LHCI JSON artefacts and ingested to this dashboard weekly.
- Budget gates: The CI build fails if any sampled page scores below 95/100 on Performance, 95/100 on Accessibility, or falls outside the per-template transfer-size budget (see sustainability dashboard).
- Scope: Lighthouse scores HTML, CSS, JS, images, fonts — the full page weight as delivered to a cold-cache browser. Server response time (TTFB) is excluded from the emulated profile but monitored separately.
Real-user monitoring (RUM)
In Phase 3, this section will display live Core Web Vitals aggregates from the self-hosted Plausible analytics instance — LCP, CLS, and FID/INP segmented by page template and device type. The data feed is production-only and requires a live deployment with real visitor traffic.
RUM data — coming in Phase 3
Plausible self-hosted Core Web Vitals aggregate will appear here once the production site is live and accumulating real-user data. The Lighthouse CI scores above are the primary quality gate until then.
