Post-completion shouldn't be this painful
Every completion triggers a cascade of deadlines, filings, and follow-ups. Miss one and your client pays the price.
14 days to file SDLT
Miss the deadline and your client gets an automatic £100 penalty — rising to £200 after 3 months, plus daily penalties and interest.
Manual re-keying
The same client, property, and transaction data gets typed into SDLT forms, Land Registry applications, and your case management system separately.
No visibility
Which completions need SDLT filing? Has the SDLT5 come back? When does the priority search expire? It's all in someone's head or a spreadsheet.
