A multi million pound design and build project for a national electrical wholesaler is nearing completion.
Final fit-out is under way at a 14,526 sq ft unit for Edmundson Electrical, a development that completes Conder Developments' Ascot Business Park, where a 15-year lease has been agreed on the trade counter unit in Longbridge Lane.
It will become one of more than 250 outlets operated by the wholesaler.
The company is relocating from a smaller unit in Ascot Drive and is expected to open within the next few weeks.
Agents Salloway Property Consultants secured the deal on behalf of landlord Conder Developments, part of the CWC Group, headed by Charles Clowes.
It is the final piece in the Ascot Business Park jigsaw as the 10-acre site is now full, providing a home to a wide range of businesses.
Conder Developments managing director Paul Shanley said: "Edmundson Electrical see Derby as quite an active market. It is a massive organisation with a huge turnover and moving from their premises in Ascot Drive represents a significant expansion for them.
"It is the last unit on the Ascot Business Park so this deal ends our involvement as developers. This site has created hundreds of jobs since its inception and demonstrates our continuing investment and confidence in Derby.
"I wouldn't be surprised if there were around 1,000 people working there.
"Pattonair is the biggest employer there but there are a number of successful growing businesses such as Pentaxia and it has been a real success story."
Jenny Clarke, of Salloway, brought the deal to its conclusion.
She said: "The unit at Ascot Business Park is modern and well equipped, which is perfect for this growing business.
"Edmundson Electrical was looking to relocate to more modern premises, and we have managed to work with both them and the landlord to secure a deal suitable to both parties."
Edmundson Electrical sells products such as cabling, lighting, electrical testing equipment, renewable technologies and items for heating, ventilation and air-conditioning systems.
A spokesman for Edmundson Electrical said: "Since our initial discussions with Conder, the deal progressed smoothly with the team.
"Derby City Council was supportive in the planning consent and the construction works have been completed in record time with practical completion achieved as promised.
"We look forward to providing the benefits of a larger and new facility to our customers in Derby."
