Tip: Optimise images

We estimate potential to save at least 54kB* by optimising images:

featured-lvi-night.jpg is 366kB
4f8a7241-374b-6b43-c... is 205kB and could be 37kB smaller
christmas-programme-... is 159kB and could be 17kB 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:

122df80e-8232-6920-fea2-346a3b... is 4.2MB
2ddbc3af-eb47-40fb-397e-e0e939... is 2.6MB
webpack_federation.js is 122kB
icons.svg is 105kB
clay.css?browserId=chrome&them... is 100kB
js?id=G-Y1GX2F6NM3 is 97kB
cookieControl-9.x.min.js is 95kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 97kB
Civic uses 96kB
Browsealoud uses 289kB
Facebook uses 76kB
Google Fonts uses 65kB

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.
