  CO2 estimatePage size

  Note: from 1st November 2022 we adopted version 3 of the methodology for estimating CO2 emissions. This will tend to lower CO2 estimates for a given size.

  Tip: Optimise images

  We estimate potential to save at least 219kB* by optimising images:

  1. Hero_banner___Bedfor... is 475kB and could be 62kB smaller
  2. parade_in_market.jpeg is 442kB and could be 65kB smaller
  3. 477_5_Havering_Foste... is 294kB and could be 62kB smaller
  4. Hero_banner___Romfor... is 216kB and could be 29kB 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. cc.js?renew=false&referer=www.... is 273kB
  2. recaptcha__en.js is 220kB ×4
  3. consent-sdk-2.2.js is 88kB

  There are 3 duplicate resources included on the page.

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Cookiebot uses 399kB
  2. Google CDN uses 1.0MB
  3. Other Google APIs/SDKs uses 50kB
  4. Council ad Network uses 53kB
  5. Google Fonts uses 38kB

  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.
