Only Openreach can move your line and they are unlikely to do so to a temporary fixture such as a caravan. How far is it away from the place you are renovating, would cordless phones and wireless broadband not do the job?
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here: How to contact TalkTalk Broadband - Help & Support.
