All correctly completed applications are being processed within the timescales of the service you applied for, which is approximately 10 weeks for a renewal application.
On their website the current time for a renewal is 5 weeks – with the ‘please allow 10 weeks’ comment on the page too – so hopefully the 10 week is their ‘cover themselves’ limit and the actual processing times on the site are nearer the length of time it’s taking. They can do it – mine took 20 days from application online to approved, and this is for a 1st passport and there was an interview in that process too – just waiting for the on the way update now – so don’t lose hope it probably won’t be 10 weeks – fingers crossed.
