In general, in the UK, if you take the photo from public land you can usually photograph and sell prints of what you can lawfully see, even if private property appears in the image. Public highways, pavements, and many public rights of way are typically treated as public places.

You do not normally need permission from every landowner whose land appears in the frame. If that were required, most landscape and street photography would be impossible.

However, there are some important exceptions:

• Certain sensitive sites, such as some military locations, may have specific restrictions.
• Some buildings may involve copyright or other rights issues, although UK “freedom of panorama” generally allows photos of buildings and public scenes from public places.
• If you are standing on private land, the landowner can set conditions, including restrictions on commercial photography.

So the key question is usually where you were standing when you made the image. If it was a genuinely public place, selling prints is generally allowed, subject to the limited exceptions above. If in doubt on a specific location, check local rules or get legal advice.
