About 632 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.5 s faster on a phone.

28 files are served with short cache lifetimes, so returning visitors download them again (241 KiB).

39 images could be 1.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 800 ms faster on a phone.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 20.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 20.6 s. Good is under 3.8 s.

Visually, the page fills in at 8.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 405 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 113 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 0.9 s to 1.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.7 MB in 356 requests on a phone: images 2.6 MB (46), scripts 1.9 MB (127) and other files 891 KiB (140). Under 2 MB keeps phones on slow connections fast.

33 images (2.5 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

24 images further down the page (1.8 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

New_Website_750x.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example STCUK_Trading_Cards_UK_Web_GraphicsArtboard_1_550x.png at 359 px wide, shown at 119 px. Resized copies would save about 1 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.62 g of CO₂e: 194.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

14 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (6 elements).

Your meta description is 267 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (WebSite) but with 1 problem, for example “ld+json block 1 is not valid JSON (Expected ',' or ']' after array element in JSON at position )”.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.
