Are All ADR Services Created Equal? Lessons from Foxtons, TDS, and the Hidden Risks in Agency Contracts

When most people think about signing a contract, they assume that including an ADR (Alternative Dispute Resolution) clause is a safeguard. It is supposed to protect both parties in case of disputes, offering mediation or arbitration without going to court. The reality, however, can be far murkier. Not all ADR services are created equal, and using the wrong one—or trusting that a standard industry contract will protect you—can leave you exposed to unfair costs and biased adjudication. This story and analysis explore the hidden pitfalls in agency contracts, using my own experience renting a house in Islington with Foxtons and the TDS tenancy deposit scheme as a cautionary tale.

The story: a 6 month tenancy in Islington and a costly “cleaning dispute”

After a long flight into London, I arrived at a rented property managed by Foxtons, one of the city’s largest and most aggressive estate agencies. The house had not been cleaned prior to my arrival, and we were delayed hours waiting to enter while they did a rush job. When we were finally given the keys we entered to find the carpets wet and the house still dirty. We then continued to maintain the property in pristine condition throughout our tenancy. By the time we left, it was unarguably cleaner than when we entered having being cleaned professionally.

Despite this, Foxtons charged us £350 for “end-of-tenancy cleaning.” Naturally, I disputed the charge, providing photographs and evidence demonstrating that the property was spotless. My case went through the Tenancy Deposit Scheme (TDS), the official ADR provider for deposit disputes in the UK. To my surprise, and frustration, the adjudicator found in favor of the agent. How could this happen?

Why ADR can be biased

First, it’s important to understand how TDS and similar deposit schemes operate. While technically neutral, these schemes are funded by landlords and letting agents. Tenants do not pay to participate, creating a structural incentive for adjudicators to defer to the professional documentation provided by agents. In my case, Foxtons submitted a check-in/check-out inventory report and an invoice from a cleaning company that, according to multiple reports, has ties to the agency itself.

Many tenants have reported similar experiences: cleaning invoices are often inflated, submitted by contractors who have a relationship with the agency, and sometimes issued even for properties that are already clean. The ADR process generally treats these documents as authoritative, while tenant evidence—photos, videos, written statements—is given less weight. The result is a systemic bias toward agents, reinforced by the adjudicator’s adherence to standardized rules and paperwork.

The hidden contractor problem

In the UK rental market, it is not unusual for agencies like Foxtons to have preferred cleaning contractors. These companies may receive kickbacks, incentives, or retainers to deliver the highest possible invoice. Their work often consists of little more than producing a bill, not actual cleaning. This makes the tenant liable for maximum charges, even if the flat was cleaned appropriately or even better than when they arrived.

Because TDS adjudicators typically do not investigate the relationship between agents and contractors, disputes are often resolved against the tenant. Independent forums and reports from tenants indicate that over half of all disputes brought to TDS relate to cleaning. The combination of subjective standards of cleanliness, the reliance on agent-selected contractors, and structural funding biases makes a fair outcome difficult to achieve.

Not all ADR is created equal

This is why it is essential to recognize that ADR services vary dramatically in quality and neutrality. In my own research comparing five widely used UK and Portuguese real estate contracts—from Lexpoint, IHM, Infraestruturas de Portugal, Contractuall, and Barreiro Municipality—not one specified an ADR process or escrow arrangement

By contrast, some professional ADR organizations, particularly in Portugal, are fully independent and neutral. Examples include:

• Centro de Arbitragem Comercial (CAC)
• ARBITRARE (for IP or tech-related disputes)
• Centro de Arbitragem da Câmara de Comércio e Indústria Portuguesa
• Concórdia

Using these organizations ensures that decisions are made by trained, neutral arbitrators, not employees or affiliates of the industry party. Unlike TDS, they consider all evidence and disclose conflicts of interest, reducing the likelihood of biased outcomes.

The structural flaws of industry-funded ADR

When an ADR service is funded by the party that stands to benefit from the outcome, it’s not hard to see why systemic bias can occur. In tenancy deposit disputes, agents often have aggressive tendencies, inflated invoices, and a clear incentive to maximize deductions. Adjudicators, relying heavily on documentation provided by the agent, may award sums that seem unfair to the tenant, even in the presence of strong evidence. Online forums, Reddit threads, and legal complaints against TDS reflect this reality.

Tenant complaints often highlight three key issues:

• Pre-arranged contractors: The agent’s chosen contractor may inflate costs or issue invoices for minimal work.
• Subjective standards: “Acceptable cleanliness” is interpreted loosely, allowing the agent to claim additional work is required.
• Structural bias: ADR providers funded by agents may unconsciously or systematically favor the party that pays them.

How to protect yourself

Given the risks, it is crucial to take proactive measures when entering contracts and drafting ADR clauses:

• Specify neutral ADR: Name an independent, reputable arbitration or mediation center in your contract.
• Clarify decision-makers: Identify who will act as arbitrator, mediator, or assessor, ensuring they are independent and experienced.
• Set compensation rules in advance: Define acceptable costs, methods of calculation, and dispute protocols to avoid arbitrary charges.
• Use escrow accounts: Hold deposits in a neutral escrow until obligations are met. Release should be conditional on mutually agreed evidence or adjudicator decision.
• Document everything: Photos, videos, timestamps, and written records provide crucial evidence that can influence impartial ADR decisions.

Walking into a contract assuming that a standard ADR clause protects you can be dangerous. Without specifying the ADR body, the scope of evidence, and neutral decision-makers, you may inadvertently subject yourself to biased outcomes, inflated costs, or systemic exploitation.

Case study summary: Foxtons, TDS, and systemic risk

My tenancy experience in Islington is instructive for anyone signing agency contracts. Key takeaways include:

• The agent submitted a cleaning invoice from a contractor with ties to them, inflating the total cost.
• The TDS adjudicator ruled in favor of the agent, relying primarily on documentation rather than tenant evidence.
• Online reviews, forums, and legal complaints indicate this is a common, systemic problem, not an isolated incident.
• Industry-funded ADR schemes are prone to bias and can generate unexpected, unfair costs.
• Without specifying neutral ADR, independent evaluation, and escrow arrangements, tenants are exposed to risk.

Conclusion

The moral of the story is simple: not all ADR services are equal. While including an ADR clause in a contract is often advised, its effectiveness depends entirely on how the clause is drafted and which service is specified. Industry-funded schemes like TDS, while official and legal, can be structurally biased in favor of the agent or landlord, particularly in subjective matters like cleaning costs.
