We use cookies to give you a better website experience.

Like many websites, in addition to the information which you supply to us, this Site automatically collects information and data through the use of cookies.

Cookies are small text files the Site can use to recognise repeat users and allow us to observe behaviour and compile aggregate data in order to improve the Site for you. For example, cookies will tell us whether you viewed the Site with sound or with text on your last visit.

With your consent, we use Universal Analytics on our Site. This means we use cookies to count the number of unique and return visitors to our Site as well as other data to help us monitor and improve use of the Site.

The Site hosts links to various social media channels and offers options to ‘share’ information. When selecting a link and opting in to such a service, you may be presented with a cookie. We are not responsible for the content of third party websites and does not control the dissemination of these cookies. Please check the relevant third party website for further information.

Cookie banner

We set essential cookies so we can present our cookie banner to you, and to record your consent preferences.

  • cookie-agreed-version


We use Matamo to provide privacy-first, cookieless analytics.

There may still be a few essential cookies created in specific cases:

  • when you exclude yourself from being tracked using the cookie method or using the iframe opt-out method, Matomo will create a cookie piwik_ignore set on the domain of your Matomo server (a temporary short-lived cookie called MATOMO_SESSID will also be created).
  • when you’re asking for consent before tracking visitors, two cookies may be created: mtm_consent and mtm_consent_removed.
  • _pk_testcookie is also created without any identifier and is directly deleted (it is only used to check whether the visitor’s browser supports cookies)

Universal Analytics

We use Universal Analytics to collect anonymous information about how our site is used by visitors. We compile reports on information such as the number of visitors to the Site, where they come from and what they click on, to help us improve the Site. These will not be set until you consent.

The website uses YouTube's more privacy-friendly domain to embed videos on the website.

However this still utilises some local storage to function and adds cookies when a video is played. Therefore we have a separate prompt advising users of this to seek their specific consent.

Once set, this preference is remembered via the following cookie:

  • nhlf_yt_consent

If consented, YouTube then sets the following cookies on the user's browser:

  • __Secure-3PAPISID
  • __Secure-3PSID
  • SID
  • SSID
  • __Secure-3PSIDCC
  • HSID
  • NID
