Cookie Policy

The cookies and similar technologies we use, and how to change your choices

Last updated: 5 November 2026

1. What cookies are

Cookies are small files that a website stores on your device. Similar technologies, such as browser storage and scripts that read information from your browser, work in a comparable way. The law treats them alike, so "cookies" in this policy covers both.

Some are needed to make a site work. Others need your consent, or, for some statistics, a clear notice and a simple way to object. This website works fully whatever you choose, including the contact form.

2. What we use

Remembering your choice (no consent needed)

NameProviderWhat it doesHow long
dn_consent (browser storage, not a cookie)DataNetRemembers your cookie choice so we do not ask on every pageWe ask you again after 6 months

Google Analytics (only if you accept)

These help us see how the site is used, such as which pages people visit, so we can improve it. They are not set, and Google Analytics is not downloaded, unless you press "Accept analytics".

_gaGoogle AnalyticsGives your browser a random ID so visits can be countedUp to 6 months after your last visit
_ga_5G8NFXHZY8Google AnalyticsKeeps track of your visit for our Google Analytics accountUp to 6 months after your last visit

Google Analytics may record pages viewed, how you reached the site, your device type, your approximate location, and actions on the site such as sending the contact form or clicking a phone number or email address. It does not record what you type into the form. Google says it does not log or store IP addresses from UK users. The Google Analytics tag on this website is set up with Google signals and advertising personalisation turned off.

Vercel Web Analytics (no cookie, on unless you reject)

We use Vercel Web Analytics, from Vercel Inc., to count page views in aggregate so we can improve the site. It sets no cookies and writes nothing to your device. Its script does check your browser storage for an item called __va_attribution, which this website never sets. It uses the page address, the referring site, your browser, operating system and device type, and your approximate location. Vercel says it identifies visitors by a hash created from the incoming request, and that the visitor session lifespan is automatically discarded after 24 hours.

We rely on the exception for statistical purposes in the Privacy and Electronic Communications Regulations, which allows this without consent as long as we tell you and give you a simple way to object. To object, press "Reject analytics". Page views stop being counted straight away, and the script is not loaded on your later visits. If your browser blocks storage we cannot remember this, so we will ask again on your next visit, and the first page you view may be counted before you answer.

Google Maps (only if you press "Load map")

Some pages can show a map from Google. It does not load until you press "Load map", and we do not remember that choice, so each page asks again. If you press it, your browser connects directly to Google, which receives your IP address and our website address, and may set or read its own cookies, especially if you are signed in to a Google account. We do not control these.

If you do not press it, nothing connects to Google for the map. The "View Larger Map" link opens Google Maps in a new tab instead.

Advertising and social media

This website does not set advertising cookies or use social media tracking.

3. Your choices

When you first visit, a banner asks you to accept or reject analytics. Rejecting is as easy as accepting, and Google Analytics does not load until you accept. Vercel Web Analytics runs unless you reject. Maps only load if you press "Load map", whichever you choose.

You can change your mind at any time using "Cookie Settings" at the bottom of our pages. If you reject, or withdraw consent, we stop Google Analytics and remove its cookies from your browser, and Vercel Web Analytics stops counting your page views. Anything Google Analytics had already queued from before you rejected may still be sent within a few seconds.

Once those cookies are gone we cannot tell which earlier statistics came from your browser, so those records stay in Google Analytics until the end of the retention period in our Privacy Policy.

You can also block or delete cookies in your browser settings. AboutCookies.org explains how.

We will update this page and the date at the top if the cookies we use change. If the change needs your consent, we will ask you again.
