bpcventilation.com website review

20 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

About 640 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.0 s faster on a phone.

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (POWr, Google Tag Manager and Cookiebot and others), adding 1.7 MB and 1.2 s of main-thread time.

16 files are served with short cache lifetimes, so returning visitors download them again (313 KiB).

POWr costs a phone 372 ms of main-thread work and 62 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Google Tag Manager costs a phone 313 ms of main-thread work and 518 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

A phone's processor spends 3.5 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,818 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

powrcdn.com costs a phone 140 ms of main-thread work and 609 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 154 KiB of CSS is downloaded but never applied on this page.

7 long tasks block the main thread while loading, the longest for 114 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

3 images could be 33 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

The page becomes fully interactive after 21.5 s. Good is under 3.8 s.

Your largest element takes 8.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to personalise content and ads, to provide s…”.

The layout shifts by 0.498 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 7.3 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 103 ms to 112 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 1.2 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.6 MB in 322 requests on a phone: scripts 1.8 MB (98), other files 884 KiB (132) and images 424 KiB (48). Under 2 MB keeps phones on slow connections fast.

Trade_Store_Banner_update_2.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 (81 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.03 g of CO₂e: 123.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links must have discernible text: 15 elements on the page fail this check, rated serious by axe-core.

8 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

3 tap targets are too small or too close together to hit reliably with a finger.

4 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 12 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h4 and h2 → h5), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

Your title is 78 characters, so Google will cut it off around 60: “BPC Ventilation | MVHR & Ventilation Systems for Trade – BPC Ventilation Store”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

Your <h1> is empty.

The homepage links to 151 pages on bpcventilation.com and 29 external pages.

https://bpcventilation.com/policies/shipping-policy, https://bpcventilation.com/collections/mvhr-diy-kits and https://bpcventilation.com/collections/mev-diy-kits have no meta description, so Google writes the search snippet from whatever text it finds.

https://bpcventilation.com/collections/piv-units took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 68 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=138004447&tm=gtm002&Ver=2&mid=79152441-940a-4981-9fa7-dc447f0049c9&bo=1&sid=ea2fcd40dda311f18fd7555d35e56478&vid=ea2ffbe0dda311f1b66701d2016cff84&vids=1&msclkid=N&gtm_.

10 of 47 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 1,088 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Microsoft Ads and Microsoft Clarity (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 10 cookies (measured from a US location before any click).

Loading the homepage contacts 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
