Tip: Optimise images

We estimate potential to save at least 48kB* by optimising images:

44158-Bus-Reform-SYM... is 162kB and could be 26kB smaller
SYMCA%20Logo_Mono_RG... is 99kB
Bus-reform-news-smal... is 69kB and could be 13kB smaller
Doncaster-Sheffield-... is 64kB and could be 8.8kB 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:

jquery-3.5.1.js is 298kB
inputmask.js is 165kB
fa-solid-900.woff2 is 157kB
bootstrap.js is 148kB
stormcaster.js is 92kB
Cabin-Regular.ttf is 77kB
Cabin-Bold.ttf is 77kB

The page uses 3 fonts which require 310kB. Could system fonts be used instead? There are 2 TTF/OTF fonts on the page - WOFF2 versions of these fonts may be smaller.

Tip: Limit third-party code

Here are the largest sources of third-party code:

freeprivacypolicy.com uses 62kB

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.
