Leisure centre charges across the county have been simplified, but there will be increases in some areas at Morpeth and Ponteland.
The transfer of these services to Active Northumberland was completed in 2014 and it inherited a complex structure as the facilities were operated by different companies.
Now the organisation, one of the county council’s family of ‘businesses’, has announced a new pricing structure that will come into effect on June 1.
Active Northumberland customers will be able to use leisure facilities county-wide as the new membership allows unlimited access to 13 gyms, 10 swimming pools and more than 350 fitness classes per week.
However, at Morpeth and Ponteland, fitness classes are up 50p per class and the increase to go swimming is 30p for adults and 20p for juniors.
Gym prices are frozen for adults and juniors, although the gym concession price has risen to £3.50 from £3.30.
There are also increases for single-use users who do not have an Active Northumberland card – up to £7.50 from £6.15 for the gym and £6.70 from £5 for fitness classes.
The council says that these prices bring the two sites in line with comparable facilities in the county.
Coun Val Tyler, policy board member for community infrastructure and culture, added: “Our parks and leisure facilities are vital for healthy lifestyles and Active Northumberland is at the heart of our strategy to encourage exercise and recreation.
“The new price structure includes a concessionary rate and this ensures our leisure centres are affordable for all.”
The new concessionary direct debit daytime multi-site membership is £24 per month for qualifying adults and £19.20 per month for juniors/students. The regular county-wide prices are £40 per month anytime and £30 per month for daytime use (before 4.30pm).
There will also be consultation with centre users about potential improvements.
