Visitors to the Houses of Parliament will be purchasing their tickets and enjoying their tours with help from a Lisburn IT company.
P2V Systems has teamed up with Gateway Ticketing Systems UK and will design, install and provide technical support for a new computer infrastructure for the famous attraction.
The firm will monitor software which controls entrance points and validates visitor tickets and will also help set up and support the processes for online sales, in-house telephone sales and sales of guided and audio tours.
The Houses of Parliament is one of the leading attractions in London with over a million visitors each year, of which 260,000 of those pay to enter.
Managing director Stephen McCann founded P2V Systems in 2008 after being made redundant.
Despite starting out in the midst of the economic downturn, Mr McCann said the company is thriving and now employs 11 people.
The company operates globally and has consultants in Belfast, Donegal and London.
"We expect the business to grow by a further 40-50% within the next year," he said.
"Working on such a high profile London project is an exciting development for the company and follows a concerted effort to develop export sales.
"We first started out working with Gateway on the ArcelorMittal Orbit attraction, the large sculpture built in London to mark the 2012 Olympics.
"They were having problems with the software so we travelled to London to offer our services and that was the start of a very productive working relationship."
"We have worked very well together now on a number of projects. Gateway will take the lead on running the software but we will still monitor everything from Lisburn."
Ticketed tours of the Houses of Parliament are available on Saturdays throughout the year and on most weekdays during Parliamentary recesses. Visitors can tour the Queen's Robing Room, Royal Gallery, Lords Chamber, Central Lobby, Commons Chamber and medieval Westminster Hall.
Amy Pitts, head of visitor services and retail at the Houses of Parliament, added that the new system was enabling more flexibility and improving the visitor experience.
Gateway Ticketing Systems UK was established in 2012 and runs ticketing for eight attractions.
