A Nottinghamshire-based company is playing an important role in one of the biggest conversion programmes in retail history.

Leading line-marking company Riggotts, the largest of its kind in the UK, is working with supermarket group Asda as it transforms the UK Netto stores it has acquired into new local Asda Supermarkets.

Riggotts, of Newark, is line-marking car parks and other areas in an industry-leading conversion which, at its peak, has seen Asda closing, refurbishing and re-opening up to eight stores each week - the last of which, at Southampton, re-opened in November 2011.

The redevelopment programme has created 2,500 new jobs and Asda will finish the year with almost 180 new-look local supermarkets.

Nick Riggott, commercial director at family owned Riggotts, said: "It has been a very ambitious but highly successful conversion scheme and we are delighted to have played our part in its completion in such a short space of time. We have been working to some very tight deadlines because it was vital that the stores were re-opened as quickly as possible without sacrificing quality."

Riggotts, who are meeting the increasingly tough requirements of internal and external line marking and surface coating contracts with a range of state-of-the-art products, have also been responsible for the restoration of Asda's car parks, and other areas, throughout the country following damage caused by the severe winter of 2010-2011.

In a bid to become the safest road and surface-marking company in the UK, Riggotts have also invested £60,000 in an overhaul of its health and safety, quality and environmental policies to secure a level of accreditation which no other UK lining company holds.
