Office Fit-Out Contractors Delivering Across the UK

The clearest sign is a lease commitment with a move-in date that's closer than you'd like. Office fit-outs take longer than most clients expect — a typical Category B fit-out of 5,000 sq ft takes 8–12 weeks from contract to handover, and that's when the programme is managed properly. If you're trying to coordinate trades yourself, add 30–50% to that estimate.

Other warning signs: you've received quotes that vary wildly in price and scope, you can't get a clear answer on what's included and what's a variation, and the contractors you've spoken to can't show you a detailed programme. A quote without a programme is a guess. A contract without a programme is an invitation for delays.

If you're refurbishing an existing office rather than fitting out a new space, the warning signs are different — a workspace that no longer reflects how your team actually works, a layout that was designed for a different headcount, or a specification that's fallen behind what your staff expect. Waiting to address these issues doesn't save money. It costs you in productivity and in the difficulty of attracting and retaining the people you need.

Our two core office fit-out services map directly to the industry-standard specification levels. Category A office fit-out covers the base-build elements that bring a shell space to a condition where any occupier can move in and specify their own fit-out. This typically includes raised access flooring, suspended ceilings, mechanical and electrical first fix, HVAC distribution, fire detection, and decoration to a neutral landlord specification. Category A is usually the landlord's responsibility, but we also deliver it for developers and for occupiers who are taking a shell-and-core space and want a single contractor to manage the full programme.

Category B office fit-out takes the space to occupier-ready standard. This is where the workplace character is created — partitioning and glazed screens, meeting rooms and boardrooms, reception and breakout areas, kitchen and café facilities, bespoke joinery, AV and data infrastructure, flooring, lighting design, and brand application. Category B is the occupier's fit-out, and it's where the investment in the workspace is most visible.

We also deliver combined Cat A and Cat B programmes — taking a space from shell to occupied in a single contract. This is often the most efficient approach for occupiers who are taking a new space and want to avoid the coordination overhead of managing two separate contractors. We handle the full programme, the landlord interface, and the handover process. You get one contract, one programme, and one point of accountability.

All of our office fit-out work is underpinned by our construction project management approach — single point of contact, formal programme, and a clear handover process. You can see examples of completed office fit-out projects on our projects page.

We deliver office fit-outs across the whole of the UK. We don't restrict our work to London or the South East — we travel to projects wherever they are, plan mobilisation carefully, and price it honestly. Whether your office is in a city centre, a business park, or a regional location, you get the same team and the same standard of delivery.

UK office fit-outs come with specific regulatory and landlord requirements that vary by building and location. Licence-to-alter applications must be submitted and approved before structural or M&E work begins — and the process takes time. Building regulations approval is required for certain types of fit-out work. Fire strategy reviews may be needed when partitioning changes the means of escape. We know how to navigate all of these, and we manage them as part of the project rather than leaving them to the client.

For occupied buildings, we plan the work to minimise disruption to other tenants — controlling noise, dust, and access in line with the building management's requirements. This is standard practice for us, not an afterthought.

When you contact us, we'll ask for a brief — the space, the specification level, the programme, and any constraints we need to know about. We'll visit the site, assess the existing condition, and come back with a detailed, fixed-price proposal and a programme. No vague estimates, no provisional sums where the scope is clear.

Once the contract is signed, we agree a start date and mobilise. You'll have a single point of contact throughout — the same person who took your brief is accountable for the handover. We report to you weekly on programme and cost, and we flag issues early rather than letting them compound. Handover includes a full snagging process, O&M documentation, and a structured walk-through with you before we sign off.

Every Vantix Group office fit-out is backed by a JCT contract, full public liability and professional indemnity insurance, and a formal programme agreed before work starts. You get a single point of contact throughout — not a salesperson who hands you off to a site manager you've never met.

We price transparently. Our quotes are detailed and fixed where the scope is fixed. We don't use low initial quotes to win work and then recover margin through variations. If something changes on site, you hear about it immediately — with a clear explanation and a fair cost. Read more about how we work on our about page, or get in touch to discuss your office fit-out.
