nispares.co.uk website review

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

About 608 KiB of JavaScript is downloaded but never used on this page.

12 files are served with short cache lifetimes, so returning visitors download them again (73 KiB).

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

8 third-party services load with your homepage (Shopify, Clarity and Reviews.io and others), adding 1.0 MB and 313 ms of main-thread time.

The page has 2,515 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.2 s on main-thread work while loading, 944 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 112 ms of main-thread work and 679 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.

Polyfills for old browsers add 20 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 16 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 145 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).

2 images could be 19 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

14 KiB could be saved by minifying JavaScript.

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 14.6 s. Good is under 3.8 s.

The layout shifts by 0.315 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 149 ms to 181 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Shop Cooker Hood Carbon Filters”.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.7 MB in 293 requests on a phone: scripts 1.3 MB (99), other files 915 KiB (136) and images 217 KiB (23). Under 2 MB keeps phones on slow connections fast.

fan-oven-element-replacement-lifestyle.jpg 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.77 g of CO₂e: 92.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Alternative text of images should not be repeated as text: 4 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (10 elements).

Your <h1> is empty.

The homepage links to 344 pages on nispares.co.uk and 3 external pages.

There is no https://www.nispares.co.uk/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

We fetched 15 pages linked from your homepage (of 169 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=5713640&tm=gtm002&Ver=2&mid=0cf293a8-42dd-4757-842b-1fe57408dc3b&bo=1&sid=d47f0f40dd9311f1a6293fb319110ff6&vid=d47f3450dd9311f180964b10c85306be&vids=1&msclkid=N&gtm_ta.

Large scripts ship without source maps.

Social proof on the homepage: 12 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 499 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Ads and 1 more (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 14 cookies, 2 of them by other companies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 33 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
