I shall try to help the Minister. His document—the regulatory impact assessment—states that there will be a cost to local authorities that maintain a database. Clearly, the database that local authorities are asked to update will easily become out of date in a year, given the number of people who change homes and the number of business premises that change ownership or tenant. The alarm systems might be changed, with the introduction of new ones and the lapsing of old ones. It was in the spirit of probing the Minister about how he imagines the database will be kept up to date that we tabled the amendment. It seems extraordinary that the Government have made no estimate of the cost of keeping such a database.
