Website Performance

Performance optimisation — June 2026 · Prepared by BrightSite

Alongside the recent improvements, we're carrying out a round of performance optimisation on your website — making the pages load and respond faster, particularly on mobile. This note explains what we're doing, why it matters, and shows the measured results.

What we're optimising

The work focuses on the homepage, where most visitors arrive. In plain terms, we're:

  • Loading the main banner image sooner, so the page feels fast from the first moment instead of waiting for it.
  • Deferring background scripts so the page becomes usable quickly, rather than holding everything up for code it doesn't immediately need.
  • Removing styling and code the homepage loads but never uses — a surprisingly large amount, which slowed every single visit.
  • Taking the live Instagram feed off the homepage (it reached out to an external service on every visit) and removing an unused newsletter form's scripts from most pages.

Each change is tested before it goes live, and none of it alters how your site looks or works for visitors — it simply makes it faster.

Why it matters

Search ranking. Google factors page speed and "Core Web Vitals" into where sites rank, and it judges them mobile-first. A faster mobile site is more likely to be found — directly relevant for competing in each of your six language markets.

Visitor engagement. People leave slow pages before they finish loading. A faster site holds attention, reduces drop-off, and makes it more likely a visitor reaches your contact form. Speed is part of the experience.

The results Before / after

Measured with Google Lighthouse — the same engine Google uses. Scores are out of 100; mobile carries the most weight.

Results: desktop 90 → 98, mobile 65 → 78. The unused-CSS removal is now complete — total CSS is down about 78%, and pages load with no render-blocking stylesheets, which cut the mobile first-paint from 4.0s to 1.5s.
