Immaculate from the very beginning

The definition of immaculate is 'perfectly clean, neat or tidy' and 'free from flaws or mistakes'. 'Immaculate' has been BOK's guiding principle and it is the reason why we are today.

People and process

Immaculate results demand quality people, quality work processes and quality service standards. This is the secret of BOK's success and the reason for our visibly superior outcomes.

Quality assurance

We submit every job to two snagging checks before allowing it to be seen. This approach, along with our strict observance of timings, ensures a guaranteed 'wow factor'.


BOK was established in 2007 by Constantin Boca, with the primary objective of providing quality trade professionals to the UK construction industry. Initially run by a small team of family members, the bulk of the work in the early days was painting and decorating contracts in the office and retail sectors.


Constantin’s commitment to quality workmanship, consistently meeting tight deadlines, and cultivating the skills of his workers soon saw growth in the business, with an expansion of the service offering to include more substantial fit-out operations, including dry lining, partitioning and suspended ceilings


Year on year, BOK has added to its service repertoire and has grown and diversified into separately managed trade divisions. These span brick and block work, plastering and screeding, partitioning systems, suspended ceilings, carpentry and joinery, floor and wall tiling, painting and decoration and small/special works. The company continues to go from strength to strength, and now enjoys a solid reputation for excellence in quality of workers and building product, among clients and partner contractors alike.
