Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 10 blocking script resources and 6 blocking CSS resources. This causes a delay in rendering your page.
Remove render-blocking JavaScript:
http://img01.bt.co.uk/s/assets/010616/js/btthirdpartyhead.js
...
Optimize CSS Delivery of the following:
http://img01.bt.co.uk/s/assets/010616/css/common-reset.css
...
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://assets.bt.com/v1/btcomd/assets/css/dante.sales.promo.css (expiration not specified)
...
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
None of the final above-the-fold content could be rendered even with the full HTML response.
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 53.1KiB (86% reduction).
Compressing https://edge.api.brightcove.com/playback/v1/accounts/2045965034001/playlists/3987933896001 could save 53.1KiB (86% reduction).
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 10.8KiB (29% reduction).
Losslessly compressing http://img01.bt.co.uk/products/static/img/swipe-arrows.png could save 4.1KiB (69% reduction).
...
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 608B (17% reduction).
Minifying http://www.productsandservices.bt.com/products/static/lib/opinion-lab/oo_style.js could save 608B (17% reduction) after compression.
