The cost of an after-work pint or weekend drinks will be more if visiting a Stonegate pub.
The chain, which owns bars such as Slug & Lettuce and Popworld, is set to bring in peak pricing.
This will see prices of drinks increase during peak times, such as evenings and weekends.
This will be introduced in 800 venues across the UK and the company has said this will help them continue to offer promotions such as happy hour.
The price could increase by up to 20p per pint

Stonegate, who is the UK's biggest pub chain, has said it will also help cover cost increases.
Those visiting pubs in London during peak times could see increases of around 20p per pint.
The average price of a pint in the UK sits around £4, according to the British Beer & Pub Association, although this is higher in London.
This has been described as "dynamic prices" and similar tactics are used in other industries.
Transport companies such as Uber use "surge pricing", where costs increase during peak times when there is more demand.
The chain trialled a similar tactic before during football World Cup tournaments.
Pint prices increased by up to 50p a drink when England matches were on.
Stonegate is not alone as many food and drink chains will often have varying prices.
They can change depending on location, the time of day and if there are any events on nearby.

STONEGATE
A Stonegate spokesperson said: "Like all retail businesses, we regularly review pricing to manage costs but also to ensure we offer great value for money to our guests.
"This flexibility may mean that on occasions pricing may marginally increase in selective pubs and bars due to the increased cost demands on the business with additional staffing or licensing requirements such as additional door team members."
Stonegate pubs offer different discounts on food and drink at different times of the week.
Slug & Lettuce offers 2 for 1 cocktails at certain times on most days of the week.
