The House Mill has graced the Lea Valley for 250 years, but its doors have been closed too long. Londoners deserve a House Mill that is open, vibrant and alive all year round.

Your action today can help make that happen. Whether you add your name, share your story, or join the movement, you are helping to unlock a landmark held in trust for you and your community — and to ensure its next 250 years truly serve the public.

What you can do now

• 🖋️ Sign the petition: Add your name to our open letter to the Charity Commission, Historic England and your local representatives, urging action to secure professional leadership and management for year-round public access and a cultural programme worthy of this landmark.

  Other actions:

• 📣 Spread the word: Help the campaign reach more people. Post on social media: “London’s lost cultural landmark deserves to live again. I’ve signed to #ReclaimyoUrHouseMill because what’s happening right now is a #RUHMdeal for London.”

• 💬 Share your story: Tell us what the House Mill means to you. Have you tried to visit and found it closed? Do you live nearby and want to see it open, welcoming and alive? Your experiences strengthen the case for change. Share your story publicly on social media using #ReclaimyoUrHouseMill or #RUHMdeal and we may feature it here on our site.
