In short: A deed of variation changes the terms of an existing lease, for example to correct a defect, update insurance or repair clauses, or add rights such as parking. With a cooperative landlord and lender, it can be done in a few weeks. Delays usually come from slow responses, lender consent or disagreement over terms and costs. (Deeds of variation for wills are different and must be made within two years of death.)
| Common reasons | Why it matters |
|---|---|
| Defective lease clauses | Lenders may refuse mortgages on defective leases |
| Ground rent changes | Onerous ground rent can make a flat hard to sell |
| Alterations and use | Permission to change layout or use |
| Adding rights | Parking, bike storage or access rights |
