Not necessarily. Presumably your house is unreigstered. A simple check with the Land Registry will confirm.

See a local solicitor sooner rather than later, to apply for first registration. There is a procedure in place for doing this where deeds are lost or stolen - see Land Registry practice guide 2 (http://www.landregistry.gov.uk/assets/library/ documents/lrpg002.pdf)
