Commercial Property Services
Our commercial work covers retail, office, industrial, portfolio and mixed use properties, with instructions ranging from single assets to complex portfolios.

We provide independent commercial property valuations for a wide range of purposes, including acquisitions, disposals, rent reviews and lease renewals.
All valuations are undertaken by experienced RICS Registered Valuers and prepared in accordance with RICS professional standards. Where required, we provide formal Red Book Valuations, giving clients and advisers confidence in both the process and the outcome.
Our valuation advice is practical, evidence-based and clearly explained, supporting informed commercial decisions.
Rent Reviews and Lease Renewals
Barnes & Barnes acts for both landlords and tenants in rent reviews and lease renewal negotiations. Our aim is always to provide balanced, well supported advice and to help achieve sensible outcomes while minimising time, cost and uncertainty.
Our services include:
Assessment of rental value
We carry out a detailed review of the lease documentation, including any licences for alterations, alongside a physical inspection of the property and analysis of relevant market evidence. This allows us to provide a clear, reasoned opinion on rental value.
Negotiations
We can manage the negotiation process on behalf of either party, working constructively to reach an agreement wherever possible. Our approach is measured and commercial, with a focus on achieving a fair result.
Third party determination
Where agreement cannot be reached, we can prepare written representations for submission to arbitrators or independent experts, supporting dispute resolution with robust evidence and clear professional opinion.
