What does CAT A vs CAT B office fit‑out finance mean — and can UK Business Loans support both?

Summary (quick answer): CAT A refers to a landlord‑level basic workspace handover (blank canvas with core services); CAT B covers tenant‑specific finishes, partitions, furniture and branded systems. Both CAT A and CAT B projects can be financed, but they often require different funding structures—phased drawdowns, equipment leasing or contractor‑backed facilities for CAT B; bridging or commercial finance for larger CAT A works. UK Business Loans helps businesses from £10,000 upwards by matching them with lenders and brokers who specialise in fit‑out funding. Get a Free Eligibility Check: Get a Free Fit‑Out Quote.

Intro / Quick answer

CAT A and CAT B are standard industry terms used in UK commercial property to describe two different stages of office fit‑outs. CAT A is the landlord‑facing delivery: a functional space with core mechanical, electrical and structural finishes. CAT B is tenant‑facing and includes partitions, reception areas, bespoke M&E, furniture and branding.

Both CAT A and CAT B projects can be financed. The best finance depends on project size, asset type and lease position: smaller, furniture/IT‑heavy CAT B jobs frequently suit leasing or asset finance; larger structural CAT A or combined projects often use staged commercial loans, bridging or contractor‑backed facilities.

What is a CAT A fit‑out?

Definition: A CAT A fit‑out delivers a basic, usable space ready for tenant customisation. The landlord or developer usually hands over the shell and core or a CAT A finish depending on the lease. A true CAT A is intended to meet building standards — not tenancy branding.

Typical works & deliverables:

• Raised access floors or finished concrete with core access
• Suspended ceilings, basic light fittings and emergency lighting
• Basic HVAC (heating, ventilation and air‑conditioning)
• Core sanitary provision and basic plumbing (usually for a kitchenette/tea point)
• Fire detection & alarm systems to building standard

Indicative costs (2025 guidance, subject to location/spec): around £150–£400/m² for standard CAT A work in many UK regions. Central London and high‑spec buildings are typically higher. Who pays? Either the landlord (as part of development) or the incoming tenant depending on lease negotiation and incentives (for example, rent‑free periods or tenant improvement allowances).

Short example: A landlord refurbishes a former industrial floor to CAT A and markets it to creative occupiers; the incoming tenant later pays for a CAT B to insert studios and meeting rooms.

What is a CAT B fit‑out?

Definition: CAT B describe tenant‑specific fit‑out works — partitions, bespoke joinery, feature lighting, AV, furniture and branding that make the space functional for the tenant’s business.

Typical works & deliverables:

• Internal partitions, reception and meeting rooms
• Decorative finishes, feature lighting and branded elements
• IT, AV systems, raised floors finished with carpets/tiles
• Bespoke joinery, kitchenettes, client areas and breakout space
• Furniture and specialist equipment

Indicative costs: typically £400–£1,500+/m² depending on specification — high for premium, hospitality or tech fit‑outs. Tenants normally fund CAT B; these are often capital expenditures that may be depreciated or treated according to the tenant’s accounting and lease terms.

Short example: A marketing agency funds a CAT B to build client presentation suites and collaboration zones, using a mix of asset finance for AV and a staged loan for construction milestones.

What types of finance suit CAT A and CAT B works?

Overview: Both CAT A and CAT B can be financed, but the funding product should match what’s being paid for and how the assets are treated on balance sheets. Lenders assess whether the spend creates tangible, saleable assets and whether the lease length and landlord consents reduce risk.

Common finance types and how they map to fit‑outs:

• Term business loans: Flexible for medium‑sized CAT B or combined projects; unsecured or secured against business assets.
• Commercial bridging finance: Short‑term solutions where speed is essential (useful if you need to start works before longer financing completes).
• Staged or contractor‑backed facilities: Lenders release funds to the contractor against certified milestones — ideal for larger CAT A/CAT B packages.
• Asset finance / hire purchase / leasing: Best for furniture, IT, AV, kitchen equipment or other tangible items in CAT B.
• Invoice finance or overdraft: Cashflow support during the construction period when suppliers need paying sooner than lender drawdowns.
• Phased funding or retention structures: Protects both owner and contractor by holding retention until snagging is complete.

Which lenders prefer which projects? High‑street banks often support larger, lower‑risk commercial loans for established companies. Specialist lenders, challenger banks and broker panels are more experienced with bespoke phased fit‑out facilities, equipment leasing and bridging solutions.

Costs, tax & landlord/lease considerations

VAT on construction and fit‑out work can be complex (zero‑rate vs standard‑rate depending on circumstances). For tax treatment — capital allowances or revenue expense — consult your accountant as we do not provide tax advice.

Lease factors lenders care about:

• Length of lease and remaining term — short leases increase lender risk
• Break clauses and dilapidations exposure — lenders prefer clarity on end‑of‑lease liabilities
• Landlord consent for alterations — lenders require evidence of permission where tenant works affect structure or services

Risks, pitfalls and how to avoid them

Common pitfalls:

• Under‑budgeting — not including design changes, VAT or contingency
• Starting works without landlord consent or formal approvals
• Poorly written contractor contracts (no fixed price, no milestones or retention)
• Using the wrong finance product (e.g., unsecured loan for large contractor works)

How to mitigate:

• Obtain fixed‑price contracts, include retention and clear milestone payments
• Keep a 5–10% contingency and confirm VAT treatment with your accountant
• Choose staged funding tied to certified certificates of completion
• Share full project documentation with lenders at enquiry stage to speed decisions
