ultimate-insulation.co.uk website review

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (FontAwesome CDN, Google CDN and Google Tag Manager and others), adding 857 KiB and 627 ms of main-thread time.

About 213 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

FontAwesome CDN costs a phone 397 ms of main-thread work and 212 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 350 KiB of JavaScript is downloaded but never used on this page.

The page has 2,330 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.1 s on main-thread work while loading, 944 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google CDN costs a phone 117 ms of main-thread work and 352 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.

3 images could be 170 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

6 files are served with short cache lifetimes, so returning visitors download them again (17 KiB).

6 long tasks block the main thread while loading, the longest for 132 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).

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.

3 KiB could be saved by minifying CSS.

The page becomes fully interactive after 11.9 s. Good is under 3.8 s.

Visually, the page fills in at 6.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Your largest element takes 3.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We and our business partners use technologies, including co…”. Most of its time is element render delay (2.6 s).

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 108 ms to 113 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 174 requests on a phone: images 2.3 MB (41), scripts 765 KiB (50) and other files 720 KiB (63). Under 2 MB keeps phones on slow connections fast.

5 images further down the page (378 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

7 images (331 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.22 g of CO₂e: 146.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 7 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: 2 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

1 visible link has no text or label, so screen readers cannot say where it goes.

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

There are 2 <h1> headlines (“Steico Insulation” and “THE independent insulation merchant.”). One clear main headline is easier for people and search engines.

The homepage links to 306 pages on ultimate-insulation.co.uk and 17 external pages.

https://www.ultimate-insulation.co.uk/pages/ultimate-insulation-contracts, https://www.ultimate-insulation.co.uk/pages/trade-accounts, https://www.ultimate-insulation.co.uk/pages/request-for-quote and https://www.ultimate-insulation.co.uk/pages/quotes-history have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.ultimate-insulation.co.uk/pages/helpful-information has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 114 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Chrome logged issues while loading the page (“Cookie”).

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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 2,458 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Meta Pixel (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 9 cookies (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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
