The developer has also said it has already seen a pickup in activity over the summer amid Labour's planning reforms.
The housebuilder said it finished 4,445 new homes in the six months to June 30, up by 5% against the same period last year.
It also marks a turnaround from the first quarter, when new home completions were down 10% year-on-year.
Persimmon said it got planning permission for 6,000 more plots so far, with "encouragingly" 1,000 of those completed in July, after Labour won the General Election.
