Factors That Affect the Fit Out Cost

Office Fit Out Contractors will generally provide estimated costs per Sq. Ft, so it is crucial that you know the dimensions and size of your new space, while the per Sq. Ft cost will depend on a number of factors, including:

  1. M&E Systems – The state of the mechanical and electrical (M&E) systems servicing the space i.e. heating, ventilation, power supply etc. If the M&E is old or not in working order, it can be a costly exercise to install new systems, so it worth appraising the M&E of any shortlisted space
  2. Raised Floors –  Raised floor allows for optimum power supply and distribution management, allowing all cabling to remain hidden underneath. If the space doesn’t have a raised floor either more innovative solutions are required. Alternatively, a raised floor needs to be fitted. Both scenarios incur additional costs.
  3. The Age of the Building – How old is the building and/or is it a listed building? There can tend to be complications with older buildings as normal wear and tear can take its toll. If the space is within a listed building, there can be an increased level of paperwork required before any fit out can begin, which incurs costs.
  4. The Specification – Ultimately, office fit out costs are heavily influenced by the specification required by the company moving into the new space, whether they desire high spec finishes, fixtures and furniture

To put that into context, if a company with 20 staff is moving to a 2,000 Sq Ft space in a modern, new building that has been fitted out to a Cat A finish, and requires just a minor fit out, the baseline cost would be between £80-100k for fit out, and £10-20k for furniture, totalling between £90k – 120k. This option is really designed for companies on a tight budget. It focuses primarily on ensuring that the space is a comfortable work environment.
