Why British ASW construction still arrived late

Britain possessed the yards to mass-produce anti-submarine escorts, but mobilisation began roughly six to twelve months later than the coming war required.

Question

If Britain had so many shipyards, why did the Battle of the Atlantic begin without a mass of new ASW escorts?

Short answer

The yards were capable, but the building programme began six to twelve months too late for the outbreak of war.

Notes

British yards could produce large numbers of anti-submarine vessels once orders accelerated. The weakness was timing rather than an absolute absence of capacity. The programme appears to have begun six to twelve months too late, and a war delayed until 1942 would have found Britain with hundreds of new escorts. In a convoy war, mobilisation lead time can matter as much as the eventual production rate.
