    Tip: Optimise images

    We estimate potential to save at least 62kB* by optimising images:

    1. poppies.jpg is 745kB
    2. remembrance-wreaths-... is 210kB
    3. stay-connected.jpg is 75kB and could be 50kB smaller
    4. southampton-internat... is 43kB
    5. civic-centre-home.jpg is 37kB
    6. col-homepage-footer-... is 24kB and could be 12kB 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:

    1. fa-brands-400.woff2 is 110kB
    2. gtm.js?id=GTM-NJPR6XX is 101kB
    3. cookieControl-9.x.min.js is 95kB
    4. jquery-ui.min.js is 68kB
    5. jquery-3.7.1.min.js is 31kB

    The page uses 1 font which requires 110kB. Could system fonts be used instead?

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 105kB
    2. Civic uses 96kB
    3. Cloudflare CDN uses 130kB
    4. jQuery CDN uses 99kB
    5. Bootstrap CDN uses 49kB

    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.
