ost cost guides stop at a national average. They tell you that a Cat B office fit out runs between £40 and £130 per square foot, add a caveat about London being more expensive, and leave you to figure out the rest. If you are planning a fit out in Birmingham, Leeds or Liverpool, that is not enough information to build a credible budget.
The three cities sit in a similar cost band, but they are not interchangeable. Building condition, Grade A supply, landlord incentive packages and local labour markets all push the final number in different directions. Understanding those variables before you sign a lease or brief a contractor is what separates a budget that holds from one that unravels mid-project.
The core principle: your fit out budget is not just a construction cost. It is a function of your city, your building, your specification and the lease negotiation that happens before a single drawing is produced.
This guide covers indicative cost ranges for each city, the factors that move pricing up or down, how to approach landlord contributions in the current market, and the cost categories that most businesses underestimate.
Regional Cost Ranges at a Glance
The table below sets out indicative Cat B fit out costs for Birmingham, Leeds and Liverpool, based on ADT Workplace’s own project experience across the three cities. These figures cover construction and installation only and exclude furniture, IT infrastructure, professional fees and VAT, each of which adds materially to the total.
| City | Low (£/sq ft) | Medium (£/sq ft) | High (£/sq ft) |
|---|---|---|---|
| Birmingham | £45 – £65 | £65 – £90 | £90 – £130+ |
| Leeds | £42 – £62 | £62 – £88 | £88 – £125+ |
| Liverpool | £40 – £60 | £60 – £85 | £85 – £120+ |
These ranges are based on ADT Workplace’s own project experience and are intended as a starting point for budget planning, not a fixed quote. Final costs depend on the specific building, the brief and the programme.
What the Ranges Actually Mean
Low specification
Covers functional meeting rooms, a kitchen, standard finishes and basic branding. Appropriate for businesses prioritising utility over identity, or for secondary offices where footfall and brand expression are less critical.
Medium specification
Introduces higher-quality finishes, more considered acoustic design and bespoke joinery. This is where most businesses operating from regional city centres land when they balance cost discipline with the need to attract and retain staff.
High specification
Applies to design-led projects with premium materials, full AV integration, architectural detailing and bespoke furniture programmes. Increasingly common in Birmingham and Leeds as prime rents rise.
Key point: the gap between low and high specification is not just aesthetic. Acoustic performance, M&E complexity and bespoke joinery are the primary cost drivers at the upper end. If your brief includes significant meeting room provision, a cafe-style breakout or a reception with architectural presence, budget accordingly from the outset.

What Changes Pricing City by City
The construction cost ranges are relatively close across the three cities. What creates meaningful budget differences in practice is the condition of the building you take, the local labour market and the supply dynamics that shape what landlords will and will not offer.
Birmingham
Birmingham is the highest-cost regional city outside London for fit out work. Prime headline rents reached £52 per square foot in Q1 2026, representing 50% growth since 2020. Grade A vacancy sits at just 3% to 5%, and the development pipeline is constrained.
For occupiers, this creates two cost pressures that do not show up in the construction benchmarks:
• Building condition: with prime supply tight, some occupiers are taking second-generation space. Stripping and making good legacy M&E, raised floors and existing partitioning can add £8 to £20 per square foot before a single new element is installed.
• Programme pressure: high demand for contractors in a buoyant market pushes labour costs upward. Compressed programmes attract a premium.
The positive counterpoint is that Birmingham landlords are increasingly offering Cat A+ space, where the base fit out is already completed to a plug-and-play standard. If you can find Cat A+ space that suits your brief, the occupier fit out cost drops significantly, though the rent premium needs to be weighed against that saving.
Leeds
Leeds is the fastest-growing prime office market in the UK by rental growth, with rents reaching £46 to £52.50 per square foot by Q1 2026, representing growth of around 17 to 18% year on year. As rents rise, occupiers tend to invest more in the quality of their space to justify the cost to their boards and their people.
In practical terms, Leeds projects are trending towards medium-to-high specification. The city’s fit out cost profile is shaped by:
• A concentration of professional services, financial and legal occupiers who set a high bar for fit out quality
• Strong demand for collaboration-first layouts with flexible meeting infrastructure
• Relatively modern Grade A stock in locations such as Aire Park, which reduces the strip-out risk present in older buildings
Liverpool
Liverpool sits at the lower end of the three cities on construction cost, with more competitive labour rates and a less constrained supply picture. Those taking space in converted or heritage buildings should factor in additional structural surveys, listed building consent where applicable, and the higher cost of working within constrained floor-to-ceiling heights or irregular floorplates.
The variable most often underestimated in Liverpool: services infrastructure. Older buildings frequently require M&E upgrades beyond what a standard Cat A condition would provide. Budget for a detailed services survey before committing to a space.
Landlord Contributions and Lease Incentives
The lease negotiation is where fit out budgets are won or lost before construction starts. In all three cities, landlords are offering incentive packages to attract occupiers. Understanding what is available, and how to negotiate it, can materially reduce the net cost of your fit out.
Rent-Free Periods
Rent-free incentive periods vary significantly by city and building, ranging from around 9 months in tighter markets to 18 months or more in locations with greater supply. A 12-month rent-free period on a 10-year lease at £40 per square foot across 5,000 sq ft is worth £200,000 towards your fit out budget.
Fit Out Contributions
Some landlords, particularly those letting second-generation space or buildings requiring repositioning, will offer a direct cash contribution towards the fit out. This is more common in Liverpool and in Birmingham buildings outside the prime core.
Key points to understand:
• They are negotiable and rarely offered upfront without a conversation
• They typically come with conditions around specification approval and programme
• A contribution towards Cat A works is different from a contribution towards Cat B (the occupier fit out itself)
• The landlord’s solicitors will want to see a reinstatement clause, which means budgeting for stripping out your fit out at the end of the lease

Cat A+ Space: A Different Calculation
In Birmingham particularly, demand for landlord-delivered Cat A+ fit out has become a significant market driver. Cat A+ space arrives with partitioning, furniture and finishes already installed to a generic standard. The occupier avoids the capital cost and programme of a full Cat B fit out, but pays a higher rent and may find the space does not precisely match their brief.
Cat A+ works well for businesses that need to move quickly and have a relatively standard brief. It works less well for businesses with a strong brand identity, specific space requirements or a culture they want the office to express.
The Cost Categories Most Businesses Underestimate
The construction cost per square foot is the figure most people focus on, and the one that most reliably holds. The categories below are where budgets slip.
Furniture and FF&E
Furniture is consistently the most underestimated cost. Based on ADT’s project experience, a realistic allowance for medium specification is £15 to £40 per square foot. For a 5,000 sq ft office at the midpoint, furniture alone is £137,500 before VAT.
IT and Data Infrastructure
Budget between £8 and £20 per square foot as a starting point. Commission a detailed IT survey before finalising your budget if the building is older than ten years.
Professional Fees
Project management, design, structural engineering and building regulations fees typically add 10% to 15% to the construction cost. On a £500,000 construction budget, that is £50,000 to £75,000 in fees.
Contingency
10% to 15% is standard for a well-scoped project. For second-generation space, heritage buildings or projects where services have not been fully surveyed, 15% to 20% is more appropriate.
The number that surprises most clients: when you add furniture, IT, professional fees and a 10% contingency to a medium specification construction cost of £75 per square foot across 5,000 sq ft, the all-in project cost lands between £600,000 and £750,000. The construction line is £375,000. The rest is everything else.
Reinstatement and Dilapidations
Most commercial leases include a reinstatement obligation. For a heavily fitted office with bespoke partitioning, raised floors and specialist M&E, reinstatement can run to tens of thousands of pounds. Factoring a dilapidations provision into your total cost of occupancy from day one is good financial discipline.

How to Build a Reliable Budget Before You Sign a Lease
Most businesses approach fit out budgeting in the wrong order: they find a space, agree heads of terms and then ask a contractor what it will cost. By that point, the building condition, the lease structure and the landlord incentive package are largely fixed. A better sequence:
1. Workplace consultancy first.
Understand how much space you actually need before committing to anything. Oversizing by 20% at £70 per square foot across 10,000 sq ft is a £140,000 construction cost error before you account for rent, rates and service charge on the surplus. Our workplace consultancy service answers the space question before the property decision is made.
2. Indicative cost plan before heads of terms.
A fit out specialist can produce an indicative cost plan from a floor plan and a brief. This gives you a credible budget range for the lease negotiation and informs what you ask the landlord to contribute.
3. Building survey before exchange.
Commission a services survey on any building you are seriously considering. M&E condition is the single biggest source of budget surprises on regional projects. Identifying a £60,000 services upgrade before exchange is far preferable to discovering it after.
4. Negotiate the incentive package with the budget in mind.
A direct conversation about rent-free, fit out contribution or Cat A condition is more productive when you can demonstrate what the fit out will cost.
5. Appoint your fit out partner before you are committed.
Involving a fit out specialist during the property search, not after heads of terms are agreed, changes the dynamic of the whole process. You go into the negotiation with real numbers, not assumptions.
The cities reward preparation differently. In Birmingham, where Grade A supply is tight, the negotiating window is shorter and landlords have less incentive to offer generous packages. In Liverpool, where supply is more available, a well-prepared occupier has more leverage. Leeds sits between the two, with strong demand but a slightly more varied supply picture.
