## FAQ
### What is the difference between FRI and a US gross lease?
Under a Full Repairing and Insuring lease, the tenant is responsible for the cost of internal repair, insurance reimbursement, and a proportional share of building maintenance via the service charge. A US modified-gross lease bundles base building services into base rent and escalates over a base year.

### What are dilapidations and how much should we budget?
Dilapidations are a tenant's contractual obligation to return the premises to the condition specified in the lease (commonly 'good and substantial repair', or to a CAT A specification). Provision £35-£75/sqft on a high-end fit-out at lease-end as a planning estimate.

### Are break clauses standard in London leases?
Yes. A 10-year lease with a tenant break at year 5 is the most common institutional structure today. Conditions on the break (vacant possession, no material breach, all rent paid) must be drafted carefully — they are the most litigated part of London office leases.

### How much rent-free is typical?
On a 10-year term, 18-24 months of rent-free is standard; trophy lease-ups can push to 30. On a 5-year term to a strong covenant, 9-15 months.

### Are business rates negotiable?
No — the rateable value is set by the Valuation Office Agency. Tenants can appeal a valuation and structure leases to allocate rates risk, but the underlying liability is statutory.
