Before You Begin: Landlord Approvals and Pre-Construction Checks

If you’re taking on a Cat A space, there are essential checks and approvals to complete before starting your Cat B fit-out. Overlooking these early steps can lead to delays, added costs, or compliance issues down the line.

Mechanical and Electrical Validations
Before any design or installation work begins, it’s vital to validate the condition and capacity of the existing mechanical and electrical systems. This ensures you’re not inheriting unresolved building issues that could become your responsibility once work starts.

From water pressure and ventilation to fire alarm loop capacity, these checks help identify whether the space meets your functional and regulatory needs — and whether any remedial work is required before you begin.

Licence to Alter
You’ll also need to apply for a licence to alter. This is a legal approval process required by most landlords before any physical works can take place. It can take time to secure, so planning ahead is key to keeping your timeline on track.

Landlord Design Pack Submission
Once your design and fit-out plans are agreed internally, you’ll need to submit a technical design pack for landlord review. This process can take several weeks depending on the level of detail and landlord response times, so it’s important to build this into your programme.

Choosing the Right Contractor
Partnering with an experienced contractor is essential. A reputable team will manage validations, coordinate landlord approvals and flag potential risks before they impact your schedule or budget. A poor contractor, on the other hand, can create unnecessary delays and liabilities, so choosing the right partner isn’t just about delivery, it’s about protection.

What Does A Cat B Fit-out Include?

By the time your landlord hands over the keys, your new office may have basic essentials in place: Raised floors, lighting, HVAC, and a few plug sockets thanks to a Cat A fit-out. But that’s just the start.

A Cat B fit-out is where the transformation happens. It all comes down to establishing a workplace that supports your team and embodies your brand.

This involves dividing the area, setting up the power and IT where necessary, planning the breakout and meeting spaces, putting in the furniture and fixtures, and incorporating your visual style.

Let’s break down what’s involved in a Cat B fit-out in more detail…

Infrastructure And Core Services

To ensure your office looks its best, it needs to operate smoothly. With that in mind, core lighting, air conditioning, and heating must be implemented. However, it’s important these key electrical components are complemented by smoke detectors and electric wiring to ensure safety amongst your office team.

Office Layout And Space Planning

Ultimately, your office space needs to be functional to promote efficiency and employee wellbeing. So, depending on your needs, you might opt for an open-plan collaborative space with private offices for your team to take calls or better focus.

Flooring And Finishes

With Cat B fit-outs, you can determine your ideal flooring and finish. The right flooring will play a vital role in your office’s functionality and contribute to the overall feel. Fancy something modern yet durable? Or looking for something bold and bright? No problem.

Interiors And Final Touches

Finally, you can splash the look and feel of your brand all over your space at this stage of the Cat B fit-out. Whether you’re opting for bold and bright colours for your meeting booths or soft neutral tones in your focus area – this is about finalising a space where your employees feel content and ready to thrive.

How Much Does A Cat B Fit-out Cost?

When it comes to the price of a Cat B fit-out, there’s no one-size-fits-all solution. The total cost will depend on the size of your area, the degree of design detail, and the calibre of materials you select.

The overall price may also be impacted by elements like custom joinery, integrated technology, acoustic treatments, and sustainability specifications.

Talking openly with your office fit-out company early on is the best way to get a clear picture of what your project could involve. They can assist in reshaping the project’s scope to fit your goals, priorities, and financial constraints.
