Tip: Optimise images

We estimate potential to save at least 26kB* by optimising images:

your-helping-hand-cr... is 1.4MB
hertfordshire-bg.jpg is 263kB
SEND-Takeover-carous... is 153kB
Housing-in-Hertfords... is 89kB
registrations-2-flip... is 44kB and could be 26kB smaller

First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

*This is an estimate from Google PageSpeed and you may get much better results than this in practice.

Tip: Large files

Aside from images, here are the biggest resources:

js?id=G-WSCQ6BK6X0&l=dataLayer... is 137kB
gtm.js?id=GTM-NKLRLCW is 122kB
cookieControl-9.x.min.js is 97kB
cookieControl-9.x.min.js?build... is 97kB
search-script.js?build=1601107 is 79kB
m=el_main is 76kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 259kB
Civic uses 195kB
Other Google APIs/SDKs uses 109kB
Google Fonts uses 97kB
Cludo uses 79kB
Clarity uses 32kB

Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
