A firm that is aiming to turn around the commercial fortunes of the solar panel market has scooped this award 

Winner: Viridian Solar

It's said that the best ideas are usually the most simple and Viridian Solar's idea to redesign the solar panel to meet the needs of the modern construction industry certainly fits that adage. Viridian understood the importance of being able to add eco technology to new buildings with minimum risk, cost and inconvenience and went about designing a low-profile, robust, inexpensive product that was quick to fit and so would not interrupt the build programme. The sleek panels protrude just 80mm above the battens, meet about 55% of domestic hot water requirements and don鈥檛 require a specialist to fit. An innovative manufacturing process allows the casing to be moulded in a single step, which also means lower cost: in fact, the price for installing the panels on one house can be less than 拢1,000.

Runners-up:

SUM

In 2002, at the age of 24, Chris Thompson and Andrew Schmidt joined forces to form SUM; Walter Toward joined a few years later.

The company, which offers a range of services such as cost consulting, project management, claims and dispute resolution and sustainability advice, has since grown to 20 members of staff, and from a turnover of 拢121,000 in 2003, it is projecting 拢950,000 in 2008.

Its projects have included Feilden Clegg Bradley鈥檚 design for a 70,000ft2, 拢13m London Greenhouse, which aims to be one of the most sustainable projects in the UK to date. It is also engaged on a 拢1.1m landmark doctor鈥檚 surgery in Otley, West Yorkshire 鈥 and it must be doing a good job on schemes like this because 96% of its clients have returned for further work.

SUM鈥檚 success is particularly impressive because it didn鈥檛 inherit any clients and hasn鈥檛 made any acquisitions 鈥 all its growth has been organic. It prides itself on offering a personal touch and the skill of its 鈥渘o-nonsense, hardworking, vibrant, dynamic鈥 staff. It is also determined to shake off the corporate image usually associated with the construction industry; its meetings take place in a 鈥渜uirky but effective鈥 shed.

The company hasn鈥檛 lost its youthful profile since it started: the average age of employees is 29. One client calls them a 鈥渂unch who can be counted on when you need them, are willing to put in the effort and are fun to socialise with鈥.

What is more, the company provides extensive support to its staff in their careers 鈥 81% of its employees are enrolled in higher education courses, and all further education is sponsored by the firm.

Vincent Stokes

In April 2003, Vincent Stokes was born out of a simple ethos 鈥 to make its clients鈥 lives easier.

It does this by consistently delivering projects on time and to budget, to an exceptional quality, by demonstrating a high level of care for its customers, suppliers and working as a cohesive team. As a member of the Lean Construction Institute, it has been involved in developing and employing lean processes and procedures in its projects. Through planning tools and regular meetings with the project team it continuously improves its processes and ensures cost and time savings for its clients and suppliers.

The refurbishment of Spelthorne鈥檚 leisure centres was never going to be an easy project. With the entire portfolio needing refurbishment and the council鈥檚 desire to keep the facilities open, both the client and contractor faced huge challenges. Nearly two years later, after spending over 拢2m, the client says: 鈥淚 wouldn鈥檛 hesitate to work with VincentStokes again, whether on a large or small project. I am certain they can deliver.鈥

Vincent Stokes is valued by its clients for its hassle-free construction solutions but it also sees how it is perceived by its suppliers as important. This is where it feels it is changing the industry 鈥 it is proud of the fact that it consistently pays its suppliers on time and respects and supports them.

The success of projects like the refurbishment of the Cannons Health and Safety Fitness estate and the 拢1.2m Fareham Leisure Centre is a testament to its approach, as is the fact that its turnover has grown from 拢1m to 拢10m since its inception.
