Attendance numbers have been capped at 800 and more recently 1,000 since the stadium reopened last month as owners Scarborough Group continue to await official safety certification upon ‘practical completion’ of the facility.
Stephen Marriott, operations director at Scarborough Group, said: “Practical completion (PC) is expected on Monday June 20. We continue to have positive dialogue with the Safety Advisory Group (SAG), who have been extremely helpful throughout the process.
“The safety certificate will be issued as soon as legally and practically possible following PC.”
Mr Marriott added: “With the support of SAG we were able to confirm an increase in capacity to 1,000 while we await PC and the safety certificate being issued, at which time our capacity will be 1,320."
