When you sell an estate or letting agency, the legal documents that give effect to the transaction go well beyond what the buyer said they wanted and what you thought you were selling. Warranties and indemnities are the mechanism by which contractual risk is allocated between buyer and seller — and understanding what they are, where the EA-specific exposures sit, and how the disclosure letter protects you is essential before heads of terms are agreed.
What Warranties Are — and What They Are Not
A warranty is a formal contractual statement of fact given by the seller in the sale and purchase agreement (SPA). It survives completion. If a warranty turns out to be false and the buyer suffers a loss as a result, the buyer can bring a claim and recover damages equal to the diminution in value of what was acquired.
Warranties are not the same as the marketing statements made during a sale. Saying your agency has “strong landlord retention” in an information memorandum is a commercial representation; warranting that the portfolio churn rate was no higher than 8% over the trailing 12 months is a contractual commitment. If the actual churn rate was 14%, the marketing statement is unlikely to found a claim — the warranty breach almost certainly will.
A critical feature of the warranty regime: disclosure removes liability. If the seller identifies a matter before signing and discloses it against the relevant warranty, the buyer proceeds with knowledge of the issue and cannot subsequently claim for it. This is why the disclosure letter — addressed below — is the seller’s primary legal protection against post-completion claims.
Standard Warranty Categories in an Estate or Letting Agency Sale
Accounts and Financial Information
The seller warrants that the disclosed financial statements give a true and fair view of the business as at the accounts date, and that there has been no material adverse change between the accounts date and completion. Because purchase price multiples in lettings are applied to AMFI, a separate warranty on the accuracy and completeness of the AMFI and managed portfolio schedule is standard in every lettings agency SPA.
AMFI and the Managed Portfolio
The AMFI schedule — setting out every managed property, the annual management fee for each, and the aggregate — is the basis on which the purchase price is calculated. The seller warrants it is accurate, complete, and reconciles to the live management platform (Reapit, Vebra, Jupix, or equivalent). Properties that appear in the schedule but have given notice, converted to let-only, or are under dispute are a warranty exposure at the deal multiple.
Management Agreements — Including the Assignment Clause Warranty
The seller warrants that a valid, signed management agreement exists for each property in the portfolio; that the disclosed agreement terms are accurate; and — critically — that the assignment of those agreements to the buyer is either permitted by the agreement terms or that landlord consent has been obtained. The assignment clause warranty is one of the most heavily negotiated in a lettings book acquisition, because most management agreements require the landlord’s consent to assign to a new operator. Without valid assignment, the buyer does not acquire the managed portfolio.
Compliance — CMP, Deposits, AML, Data Protection
The seller warrants: (i) current and uninterrupted membership of a government-approved Client Money Protection scheme; (ii) that all tenant deposits held at completion have been protected with an approved scheme within the required 30-day period and prescribed information served; (iii) registration with HMRC for AML purposes and compliance with client due diligence obligations under the Money Laundering Regulations 2017; and (iv) compliance with UK GDPR in the handling of landlord, tenant, and applicant personal data. Each of these areas carries its own regulatory penalty regime, and all four are treated as serious warranty categories by buyers.
Employment — Including Property Manager Non-Solicitation
The seller warrants that all employees have written contracts as disclosed, that no key person has indicated an intention to leave, and that all employment obligations (remuneration, right to work, holiday pay, and similar) have been met. For letting agencies, a specific and important employment warranty addresses property manager non-solicitation provisions: the seller warrants that existing employment contracts contain adequately drafted non-solicitation clauses preventing property managers from soliciting managed landlords if they leave after completion. A poorly drafted non-solicitation provision — too short in duration, too narrow in scope, or limited to the wrong geography — may be unenforceable, leaving the buyer with no contractual protection against the most common post-completion risk in a lettings acquisition.
Property and Lease
Where the agency occupies leasehold premises, the seller warrants that the lease is validly held, that there are no material breaches (arrears, dilapidations, outstanding landlord notices), and that any landlord consent required for the assignment or change of control has been obtained before completion.
Tax
In a share sale, a tax covenant requires the seller to indemnify the company against all pre-completion tax liabilities assessed after completion — covering income tax, corporation tax, PAYE and NIC, and VAT. The tax covenant operates both as a warranty and as an indemnity and is standard in almost every share sale.
EA-Specific Warranty Risk Areas
Beyond the standard categories, four warranty risk areas regularly arise in lettings and estate agency transactions.
Management Agreement Gap Rate
The gap rate — the proportion of the managed portfolio that is vacant (not generating rent) at any given time — affects both immediate fee income and the portfolio’s longer-term trajectory. A buyer will often seek a warranty that the gap rate as at the data room date has not materially worsened by the completion date. Sellers should run a current vacancy analysis and compare it to the position at the time data was disclosed. An unexplained increase in voids between data room and completion will require either a specific disclosure or a warranty negotiation.
CMP Compliance — Brief Gaps Create Warranty Claim Risk
Even a short lapse in CMP scheme membership — for example, during a transfer from one scheme provider to another — is technically a compliance breach. The scheme requires continuous membership, and a period of even a few days without cover creates a warranty exposure. Sellers should obtain written evidence of continuous membership from their scheme provider before the data room is assembled, and should disclose any historical gap with supporting documentation.
Deposit Protection — Verifiable by Cross-Reference, Indemnity Often Sought
Deposit compliance is uniquely verifiable: tenancy deposit scheme records can be cross-referenced against the let portfolio to identify unprotected tenancies. Because the exposure is both identifiable and quantifiable (one to three times the unprotected deposit amount per tenancy), buyers regularly seek an indemnity for deposit protection failures rather than relying on the warranty regime. As explained below, an indemnity claim requires only proof that the event occurred — the buyer does not need to prove diminution in business value and the claim is not subject to the basket or de minimis. Sellers who cannot confirm clean deposit compliance should expect this indemnity to be insisted upon.
Property Manager Non-Solicitation Adequacy
Even where non-solicitation provisions exist in property manager contracts, buyers will scrutinise whether they are adequately drafted. The key questions are: duration (typically 12 months post-termination), scope (managed landlords with whom the PM had a material relationship), and geography. An inadequately drafted clause — one that is too short in duration, too vague in scope, or limited to a geographic area that does not reflect where the landlords are located — may be unenforceable. Where gaps are identified, the seller will need to disclose and the buyer may seek specific remediation before completion or an indemnity for losses attributable to inadequate restrictions.
The Disclosure Letter
The disclosure letter is exchanged at the same time as the SPA. It operates in two ways: a general disclosure of the data room as a whole (so that any matter the buyer could have found in due diligence is treated as disclosed), and specific disclosures against individual warranties identifying particular exceptions.
In estate and letting agency sales, items commonly requiring specific disclosure include:
- Gap properties with identification — any managed properties that are currently void or where the tenancy is at imminent risk, identified by address
- Non-standard management agreement terms — any agreement with fee rates, notice periods, or assignment restrictions that differ materially from the standard form disclosed in the data room
- Unprotected deposits — any tenancy deposit that has not been registered or where prescribed information may not have been served in time
- At-risk landlords — any landlord who has expressed dissatisfaction, given informal notice of their intention to leave, or where the relationship is known to be fragile
- Open employment matters — any ongoing disciplinary proceedings, grievance, or employment dispute, even if the agency expects a favourable outcome
- Compliance correspondence — any correspondence with the Property Ombudsman, CMP scheme, HMRC (AML supervision), Trading Standards, or the ICO, however informal
- PM departure risk — any property manager whose departure is anticipated, or who holds relationships with landlords that represent a concentration risk to the managed portfolio
Sellers who leave disclosure letter preparation to the final week before exchange run a material risk of under-disclosure. A thorough disclosure letter, prepared with solicitors throughout the sale process, is the single most effective protection available against post-completion warranty claims. Any matter that the seller is uncertain about should be disclosed; the cost of over-disclosure is low, and the cost of under-disclosure is a warranty claim.
Indemnities vs Warranties
Where a risk is identifiable, quantifiable, and sufficiently serious, buyers will seek an indemnity rather than relying on the warranty regime. The distinction matters in three ways:
- A warranty claim requires the buyer to establish that the warranty was false and that the business is worth less as a result. It is subject to the financial cap, the basket (an aggregate threshold before claims may be brought), and any de minimis provision.
- An indemnity operates on a pound-for-pound basis: the buyer recovers the actual loss from the specified event without needing to prove diminution in business value. Indemnities typically sit outside the basket and de minimis — the buyer recovers from the first pound of loss.
In estate and letting agency sales, indemnities are most commonly sought for: deposit protection failures (identified in due diligence and quantifiable); identified employment claims (where a specific claim is known to be live or anticipated at completion); and pre-completion tax liabilities (addressed through the tax covenant in share sales).
Limitation Provisions
Warranty liability does not survive indefinitely, and sellers should ensure a clear set of limitation provisions is included in the SPA before signing.
- Time limits: general warranties are typically limited to 18 months to 3 years from completion; tax warranties and compliance indemnities are typically 4–7 years, reflecting the relevant limitation periods under statute
- Financial cap: total seller liability under all warranties is usually capped at the total consideration received; sellers should resist any cap structure that leaves fundamental warranties (title, capacity) outside a clear limit
- Basket: claims can only be brought once total notified claims exceed an aggregate threshold, typically 0.5%–1.5% of consideration — on breach of the basket, the seller is liable for all claims, not merely the excess
- De minimis: individual claims below a defined floor (typically 0.1%–0.5% of consideration) cannot be brought, preventing the buyer from pursuing numerous minor claims
- Disclosure carve-out: the seller bears no liability for matters fairly disclosed in the disclosure letter — this is the direct link between thorough disclosure and limitation of post-completion exposure
Note that indemnities — including the deposit protection indemnity and tax covenant — often sit outside the basket and de minimis, with their own specific time limits. The scope of each indemnity’s limitations should be negotiated separately from the general warranty regime.

Frequently Asked Questions
What is the difference between a warranty and a marketing representation in a business sale?
A marketing representation — a statement in an information memorandum or made during negotiations — is a commercial claim that does not usually create binding legal liability unless it amounts to fraudulent misrepresentation or falls within specific statutory protections. A warranty in the SPA is a contractual commitment that survives completion: if it is false and the buyer suffers a loss, the buyer can bring a damages claim. The distinction means sellers must be especially careful to ensure that the specific statements warranted in the SPA are accurate, even if commercial representations in the information memorandum were more loosely worded.
Why does the assignment clause warranty matter so much in a lettings agency sale?
Most management agreements require the landlord’s consent before the agency can assign the agreement to a new operator. If the seller cannot warrant that valid assignment has occurred — or that the agreements are capable of assignment without consent — the buyer may not have acquired what it paid for. This makes the assignment clause warranty one of the most important in any lettings book transaction, and sellers should review every management agreement for assignment provisions before the data room opens.
Why do buyers seek an indemnity rather than a warranty for unprotected deposits?
Because deposit protection failures are verifiable by cross-reference and the statutory penalty is fixed (one to three times the unprotected deposit per tenancy), the exposure is both identifiable and quantifiable before completion. A warranty claim requires proof of diminution in business value and is subject to the basket — meaning small numbers of unprotected deposits may not meet the threshold for a warranty claim. An indemnity avoids this: the buyer recovers the actual penalty cost from the first pound, without needing to prove business value impact. Sellers who cannot confirm clean deposit compliance should take steps to rectify failures before the data room opens.
What should the disclosure letter include in a letting agency sale?
In addition to a general disclosure of the data room, the disclosure letter for a letting agency sale should specifically identify: any gap properties and at-risk landlords; non-standard management agreement terms; any unprotected deposits; open employment matters; any correspondence with regulators (Property Ombudsman, HMRC AML, ICO); CMP membership gaps; and any property managers at risk of departure. Each specific disclosure should be clearly cross-referenced to the relevant warranty and supported by documents in the data room. Sellers should prepare the disclosure letter with solicitors from the outset of the sale process, not as a final-stage exercise.
How long do warranty claims last after completing an estate agency sale?
General warranties are typically limited to 18 months to 3 years from the completion date. Tax warranties and compliance indemnities typically run for 4–7 years, reflecting statutory limitation periods. After the time limit expires, no new claims can be brought. Sellers should ensure the SPA contains clearly defined time limits for all warranties and indemnities, and that the disclosure letter is thorough enough to remove liability for known issues before those time limits begin to run.
