During September, 'mystery shoppers' visited all 560 TICs in England including Weston-super-Mare and Gordano Services.
The annual survey aims to monitor TICs' customer care skills, and this year it focused on how well staff were able to assist disabled visitors.
'Mystery shoppers' quizzed staff on topics such as where to find suitable accommodation, their knowledge of local wheelchair hire facilities and disabled accessibility at attractions around the region.
Both Weston and Gordano TICs received perfect scores of a maximum 100 per cent - well above the regional average of 83 per cent and the national average of 72 per cent.
It means both centres are ranked in the top 15 per cent in the country when it comes to customer service.
'We are absolutely delighted with the results which show the very high level of service offered to disabled visitors at our two centres,' said Sue Cooke, TIC network manager. 'Staff must receive great credit for their commitment in providing a friendly and efficient service to all our visitors.'
