What to check before renting a warehouse in London for light manufacturing

Intro

Renting a warehouse for light manufacturing in London requires more technical checks than a simple storage unit. This checklist helps you confirm the site is operationally viable and compliant before you sign a lease.

Key technical checks

Technical failures are the common hidden costs. Confirm these items in writing where possible.

• Power and electrical capacity: kVA, three phase availability, metering, and whether tenant upgrades are allowed.
• Floor loading: maximum floor loading in kg per sq m for racking and machinery.
• Ceiling height and crane or hoist provisions: clear working height, mezzanine load limits, and lifting gear certification.
• Ventilation and extraction: suitability for processes that create dust, fumes or heat, and location of external discharge points.
• Fire protection: sprinklers, alarm systems, and fire exit routes meeting regulatory standards.

Ask the landlord for recent test certificates and an electrical installation condition report if available.

Planning, permits and environmental considerations

London planning rules and environmental controls can restrict manufacturing activities. Check these early.

• Use class: confirm the premises sit within an appropriate use class for your activity, or that a change of use is feasible.
• Environmental permits: activities creating emissions or waste may need permits from the local authority or the Environment Agency.
• Hours and noise limits: nearby residential areas may impose restricted operating hours and noise limits.
• Waste storage and disposal: confirm space for recycling and hazardous waste containment if relevant.

Getting pre-application advice from the borough planning office can avoid costly delays.

Operational access and logistics

Efficient movement of goods and staff matters more in London where space is constrained.

• Vehicle access and turning: service yard size, one-way systems, and HGV access onto the public highway.
• Loading infrastructure: dock levellers, roller shutters, ramp gradients and internal circulation.
• Staff facilities and parking: adequate toilets, break rooms and cycle storage, plus staff parking alternatives.
• Security: perimeter fencing, lighting and CCTV considerations for valuable inventory and machinery.

How to reduce risk in negotiations

Mitigate future surprises by building conditions into the lease and asking for warranties.

• Insist on written confirmation of kVA and floor loading limits in the lease schedule.
• Include a schedule of condition to limit dilapidation claims on exit.
• Negotiate a break clause or rent-free period for tenant fit out and testing.
• Use a specialist surveyor for complex machinery, and instruct a solicitor familiar with industrial leases.
