Who we work
for.

Offices

Fit-out and refurbishment, partitioning, lighting and power, and the fixed wire testing and emergency lighting checks that keep a building compliant.

Shops, restaurants and cafes

Shopfitting, shopfronts, commercial kitchens, gas safety and the works needed ahead of a food hygiene inspection, programmed around trading hours.

Landlords and managing agents

Planned and reactive maintenance, communal compliance, fire doors, and repairs to roofs, walls and external fabric across a portfolio.

Lease ends

Dilapidations and reinstatement works priced against the schedule, so the property is handed back as the lease requires.
