The UK Deal Sourcing Compliance Checklist (2026)

Deal sourcing sits inside one of the most heavily regulated corners of UK property, and most of the industry has not caught up. Research by NAPSA covered in The Negotiator looked at 500 property-sourcing businesses and found that around 90% were operating illegally on surface-level checks alone. The same coverage reports that 136 sourcing firms have been fined a combined total of more than £1.1 million by HMRC for failing to register for anti-money laundering supervision. HMRC publishes the names of businesses it penalises, so non-compliance is not just expensive, it is public.

The good news: compliance is a short, well-defined list costing less than a single sourcing fee. Here is every registration and obligation a UK deal sourcer needs in 2026, with real costs and links to the official bodies.

Why sourcing counts as estate agency work

Everything on this checklist flows from one fact: introducing buyers and sellers of property in the course of business, for gain, is estate agency work under section 1 of the Estate Agents Act 1979. Calling yourself a sourcer, deal packager or introducer changes nothing: if you introduce properties to investors for a fee, the law treats you as an estate agency business and the registrations below apply.

The compliance checklist at a glance

1. Register with HMRC for anti-money laundering supervision

This is the registration most sourcers miss and the one HMRC actively enforces. Sourcing and introducing businesses must be registered for AML supervision before trading, not after the first deal. HMRC's registration guide for estate agency businesses sets out who must register and how.

The current HMRC fees (updated 1 December 2025) are:

• £300 application fee, one-off and non-refundable, waived for businesses eligible for the small business reduction
• £400 premises fee per year for each premises on the registration
• £40 approval fee per beneficial owner, officer or manager put through the approval process
• A small business reduction refunding £500 where turnover is under £5,000 a year

Registration alone is not enough: HMRC also expects a written risk assessment, customer due diligence, record-keeping, and staff training if you have a team.

2. Join a property redress scheme

Anyone carrying out estate agency work must belong to an approved redress scheme so that consumers have somewhere to escalate complaints. There are two approved schemes:

• Property Redress lists membership from £190 + VAT per year on its entry tier, with a fee per complaint, or £280 + VAT per year on the enhanced tier
• The Property Ombudsman (TPO) lists full membership at £269.86 + VAT per office per year, with a one-off joining fee in the first year, and explicitly covers buying agents and property sourcing

Either scheme satisfies the legal requirement. Check current pricing on their sites and make sure your membership category actually covers sourcing.

3. Register with the ICO and pay the data protection fee

Sourcers process personal data constantly: investor lists, vendor details, tenancy information, viewing notes. Unless an exemption applies, businesses that process personal data must register with the Information Commissioner's Office and pay the data protection fee. Since February 2025 the fee is £52 a year for tier 1 organisations (most small sourcing businesses), £78 for tier 2, and £3,763 for the largest. The fee is the visible part; the substance is handling data lawfully under UK GDPR: keep investor data secure, say what you do with it, and delete what you no longer need.

4. Hold professional indemnity insurance

Professional indemnity (PI) insurance covers claims that your advice or service caused a client financial loss, for example a deal presented with a miscalculated return. Redress schemes generally expect members to hold appropriate PI cover, and serious investors increasingly ask to see it before paying a fee. Premiums depend on turnover and cover level, so get quotes from a broker rather than relying on figures from a course or forum.

5. Meet your Estate Agents Act obligations

Beyond registrations, the Estate Agents Act 1979 imposes conduct duties that apply to sourcing businesses:

• Give clients written terms, including all fees and charges, before they commit
• Disclose promptly and in writing any personal interest you have in a transaction
• Keep reservation fees and deposits in a separate client account, with the holding terms clear
• Do not discriminate against buyers based on whether they use services you offer

These duties have teeth: National Trading Standards can issue prohibition orders banning individuals from estate agency work entirely.

6. Disclose your fees clearly and early

Your sourcing fee, when it is payable, and whether any part of it is refundable must be clear, in writing, before an investor commits money. Burying a non-refundable reservation fee in small print is exactly the kind of practice redress schemes uphold complaints about. Fee structures, typical amounts and disclosure are covered in detail in our guide to property sourcing fees.

7. Comply with the DMCC Act 2024 material information duty

The Digital Markets, Competition and Consumers Act 2024 replaced the old consumer protection regulations from 6 April 2025. Under it, omitting material information from a property listing or deal presentation is automatically an unfair commercial practice, and the Competition and Markets Authority enforces this directly with fines of up to £300,000 or 10% of global turnover, whichever is higher. The CMA's unfair commercial practices guidance sets out the regime.

For a sourcer, material information means the facts an investor needs for an informed decision: price, tenure, lease terms where relevant, known defects, flood risk, and restrictions. In practice, a properly built deal pack is this duty done systematically. See what goes in a property deal pack for the full structure.

Step-by-step: getting compliant from a standing start

1. Set up the business properly: HMRC tax registration, a business bank account, and a client account if you will hold reservation fees.
2. Register for AML supervision with HMRC before you market a single deal, writing your risk assessment and due diligence process at the same time.
3. Join a redress scheme: Property Redress or TPO, on a tier that covers sourcing.
4. Register with the ICO and pay the data protection fee.
5. Arrange PI insurance through a broker, sized to your fee income and deal values.
6. Write your client-facing terms: fees, refund policy, service scope, and a complaints procedure naming your redress scheme.
7. Build a deal presentation standard that covers material information on every deal, so DMCC compliance is baked into the process.

What does full compliance actually cost?

Using the published figures above, a single-premises sourcing business starting from scratch in 2026 is looking at roughly £700 to HMRC in year one, £230 to £410 including VAT for a redress scheme depending on scheme and tier, and £52 to the ICO: around £980 to £1,160 for the registrations, plus PI insurance. Set against typical sourcing fees of £3,000 to £5,000 per deal, that is less than half of one fee, and the fines for skipping it start in the thousands.

Once registered, the ongoing work is process: due diligence on every client, clear terms on every deal, and complete, honest deal packs. That last part is where presenting deals properly and staying compliant turn out to be the same job.
