Introduction

If you’re planning an office move or refurbishment, one of the first questions you’ll ask is: how much does an office fit out cost?

The answer depends on several factors, from the size of your space to the level of finish required. As an experienced office fit out contractor, we support businesses across London, Surrey, Sussex, Kent, Berkshire and the wider South East in planning projects that align with both budget and long-term business goals.

How Much Does an Office Fit Out Cost?

Office fit out costs are typically calculated on a cost per square foot basis. However, no two projects are the same, and costs can vary significantly depending on the scope, specification and complexity of the works.

As a general guide, CAT A fit outs are usually more cost-efficient as they focus on base build elements, while CAT B fit outs involve a higher level of detail, design and customisation to create a fully operational workspace.

For an accurate understanding of your project costs, it’s always best to work with an experienced fit out specialist who can assess your requirements and provide a tailored proposal.

What Factors Affect Office Fit Out Costs?

Every project is different, but the key cost drivers typically include:

1. Size and Layout

Larger spaces may benefit from efficiencies, but complex layouts can increase design and build requirements.

2. Specification and Finish

High-quality materials, bespoke joinery and branded environments will influence overall cost.

3. Mechanical and Electrical Requirements

Air conditioning, lighting, power and ventilation upgrades are often a significant part of the investment.

4. Furniture and Specialist Features

Acoustic pods, meeting rooms and collaborative zones can enhance your workspace but will impact budget.

How to Get the Best Value From Your Office Fit Out

Working with a trusted design and build contractor ensures your budget is used effectively. A well-designed office should:

  • Maximise usable space

  • Support productivity and wellbeing

  • Adapt to future business needs

Taking a strategic approach early in the process can help avoid unnecessary costs and deliver better long-term value.
