Office fit-out · UK-wide
Cat A & Cat B fit-out.
Tatton Projects delivers Cat A and Cat B office fit-out across the UK, from landlord Cat A upgrades that make a floor lettable to full Cat B fit-outs that turn a bare shell into a workplace.
Project delivery
The difference between Cat A and Cat B.
Cat A is the landlord's base build: raised floors, suspended ceilings, basic services, fire detection and finished surfaces that leave a floor clean, lettable and ready for a tenant. Cat B is the tenant's fit-out: the layout, partitions, meeting rooms, kitchens, joinery, branding, lighting and workplace design that turn that empty floor into somewhere a team actually works.
We deliver both, and the shell-to-handover work in between, coordinating landlord, tenant, designer and building control so the two stages meet cleanly instead of clashing on site.
What we do
From base build to handover.
Cat A for landlords
Raised floors, ceilings, base services, fire detection and finished surfaces that make a floor lettable and pass a letting agent's inspection.
Cat B for tenants
Space planning, partitions, meeting rooms, tea points, joinery, feature lighting, acoustics, branding and the full workplace fit-out.
Shell-to-handover
A bare shell taken all the way to an occupied floor as one managed project, so nothing falls between landlord and tenant scope.
Dilapidations & reinstatement
End-of-lease strip-out and reinstatement back to the Cat A condition your lease requires.

Straight answers
Questions we get asked.
Cat A is the landlord's base finish, raised floors, ceilings, basic services and finished surfaces that make a floor lettable. Cat B is the tenant's fit-out on top: layout, partitions, meeting rooms, kitchens, joinery, lighting and branding. We deliver both.
As a 2026 guide: a Cat A refresh runs about £45–£70 per sq ft, a standard Cat B £70–£110, and a high-specification Cat B £110–£180 and up. We give you an elemental cost plan rather than a single headline number.
Yes. Commercial fit-out is delivered across the UK on selected projects, managed from Manchester with the same team on site wherever the building is.
Yes. Running Cat A straight into Cat B as one programme avoids the gap where landlord and tenant scope usually clash, and gets the floor occupied sooner.
