Resolve Lease Dispute with Agent

I am seeking a fixed-fee quote for a specific service to resolve a dispute with my corporate letting agent. I believe I am a "consumer landlord" and wish to challenge unfair contract terms under the Consumer Rights Act 2015 to force a renegotiation or exit, not to initiate possession proceedings.

1. My Position & Goal:

I own one rental property individually; being a landlord is not my main profession.

The agent's standard contract contains Clause 8.5 (making me liable for all eviction costs) and Clause 8.4.1 (automatic 24-month renewal).

I served notice to end the lease, but the agent claims it auto-renewed until 2027 due to a 4-month notice clause.

My goal is to have these core clauses declared unfair/unenforceable to break the deadlock and either secure a fair new agreement or a managed exit without punitive costs.

2. The Specific Service I Require:
I need a legally robust 'Letter Before Action' to be sent to the agent. The letter must:

Formally state my status as a consumer landlord under the Consumer Rights Act 2015.

Detail why Clauses 8.5 and 8.4.1 constitute unfair terms causing a significant imbalance.

Demand that within 14 days, they either: (a) agree to enter into formal mediation to settle the dispute, or (b) provide a lawful and costed proposal for returning the property without invoking the disputed Clause 8.5.

Be your firm's final professional step before I would need to consider issuing a claim.

3. Key Documents I Can Provide:

The signed lease agreement.

The full email chain with the agent, including their denial of CRA application.

My notice and all related correspondence.

4. My Questions for Your Quote:

Please provide a fixed-fee quote for:

Reviewing the provided documents.

Drafting and sending the specified 'Letter Before Action' on your firm's headed paper.

A brief follow-up to receive their response.

Do you offer this service, and what is the fixed fee and expected timeline?

I look forward to your reply.
