The London Bet Din has advised that currently there is no halachically permissible way to walk from Borehamwood to Edgware on Shabbat. They are continuing to look into the issue to try and find a solution. If you wish to discuss this further, please seek rabbinical advice.
Please check the Eruv map carefully before carrying or pushing buggies in these roads on Shabbat. The Eruv boundary cuts across these streets/backs of gardens and does not include every house or all pavement area.
Please note that the Eruv boundary cuts through the park. Please check the map for the boundary lines.
