Double-glazing firm CR Smith has been unveiled as the first commercial sponsor of Edinburgh's trams.

The company - which sponsored both Celtic and Rangers - will wrap adverts on 18 of the 27 trams in a two-year deal worth around £1.3m per year.

The deal was negotiated by a "unique" city partnership between Marketing Edinburgh, Transport for Edinburgh (TfE) and Edinburgh Trams, on behalf of City of Edinburgh Council.

Trams will feature individual artwork, with the designs representing some of Scotland's top attractions.

It comes after the council said it would consider plans for a £1.65m three-miles tram extension to Newhaven by 2022 next month.

Gerard Eadie, executive chairman of CR Smith, said: “This is a first.

"No one else has sponsored the Edinburgh Trams and it instantly gives us massive visibility.

“Over the past few years we have invested in our state of the art factory in Cowdenbeath, in our product range and in our people, through ongoing training and our own apprenticeship programme.

"This is a natural next step for our ongoing strategy for growth.”

Lea Harrison, managing director of Edinburgh Trams said: "With around 7,000 services running through the city every month, our trams offer fantastic exposure to forward thinking businesses.

"Customer journeys, currently standing at over 5.6 million per year, are continuing to rise as the tram becomes an ever more popular transport option.”

"Event promotions on our trams, such as the Royal Highland Show, have already proved hugely successful and we're delighted to be expanding these commercial opportunities.

"The deal with an iconic brand such as CR Smith is a first and is a significant step in our promotional strategy.”

John Donnelly, chief executive of Marketing Edinburgh said that the partnership between Marketing Edinburgh, TfE and Edinburgh Trams is a new and innovative approach to managing citywide advertising in Scotland".
