    Tip: Optimise images

    We estimate potential to save at least 11kB* by optimising images:

    1. Local_plan_image_cro... is 470kB
    2. Flag_1.jpg is 346kB
    3. Byron_Image_2.jpg is 225kB
    4. EV_On_Street_Chargep... is 106kB and could be 11kB 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. icons.data.svg.css?6cd91072b3c... is 177kB
    2. icons.data.svg.css?6cd91072b3c... is 100kB
    3. js?id=G-M5S4MNQ3H6&l=dataLayer... is 97kB
    4. gtm.js?id=GTM-5NHG2V3 is 79kB
    5. pattern-library.js is 59kB
    6. harrow.js?6cd91072b3ca284d0bfa... is 58kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 175kB
    2. Hotjar uses 61kB
    3. Cludo uses 52kB
    4. ecal.com uses 45kB
    5. Google Fonts uses 35kB
    6. Google CDN uses 32kB
    7. Cloudflare CDN uses 30kB

    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.
