Common Payment Scams in UK Construction
Common Payment Scams in UK Construction (And How to Avoid Them)
The UK construction industry is booming but with growth comes risk. Payment scams in construction have surged in recent years, targeting homeowners, contractors, subcontractors, and suppliers alike. With complex payment chains and multiple stakeholders, construction projects have become a prime target for fraudsters.
According to recent reports, invoice fraud alone cost UK victims millions of pounds, with construction among the most targeted sectors due to its fragmented payment systems .
If you’re a UK customer planning a construction project, understanding these scams is not optional it’s essential.
Why Construction Payment Scams Are Increasing in the UK
Construction projects often involve:
- Multiple contractors and subcontractors
- Large upfront payments
- Informal agreements
- Tight deadlines
This creates the perfect environment for fraud.
Scammers exploit confusion, urgency, and lack of transparency. In many cases, victims don’t even realise they’ve been scammed until the money is gone.
Additionally, fraud now accounts for a significant portion of overall crime in the UK, with billions lost annually .
1. Invoice Fraud (Fake or Altered Invoices)
What it is:
Invoice fraud is one of the most common scams in construction. A scammer sends a fake invoice that looks identical to a legitimate supplier’s invoice but with different bank details.
How it works:
- You receive an email from a “supplier”
- The invoice looks genuine
- It may say “urgent payment required”
- Bank details are changed
Once payment is made, the money goes directly to the scammer.
Why it’s dangerous:
Construction businesses process dozens of invoices weekly, making it easy to miss small changes.
Real insight:
Fraudsters often impersonate trusted suppliers and use urgency tactics to rush payments .
How to avoid it:
- Always verify bank details before paying
- Confirm changes via phone (not email)
- Use secure payment platforms
- Train your team to spot red flags
2. Advance Payment (Deposit) Scams
What it is:
A contractor asks for a large upfront payment and disappears without completing the work.
How it works:
- Attractive quote (often cheaper than market rate)
- Requests 50–100% upfront payment
- No written contract
- Contractor becomes unreachable
Real-world trend:
UK banks have reported a rise in cases where criminals take large deposits for building work and vanish .
How to avoid it:
- Never pay full amount upfront
- Use staged payments linked to milestones
- Avoid cash payments
- Always get a written contract
3. Authorised Push Payment (APP) Scams
What it is:
You’re tricked into sending money to a scammer’s account, believing it’s legitimate.
How it works:
- Fraudster impersonates contractor, supplier, or even your bank
- Requests payment transfer urgently
- You willingly authorise the payment
Why it’s common:
These scams rely on human error, not hacking.
APP scams are among the most common types of fraud in the UK .
How to avoid it:
- Double-check payment requests
- Be cautious of urgency
- Verify identity through trusted channels
- Use confirmation of payee systems
4. Fake Contractor or “Cowboy Builder” Scams
What it is:
Fraudsters pose as legitimate contractors to win jobs and extract payments.
Common red flags:
- No verifiable business details
- Fake reviews or credentials
- Extremely low quotes
- Pressure to “book now”
Industry insight:
Lack of contracts, fake credentials, and upfront payments are major warning signs .
How to avoid it:
- Check company registration (Companies House)
- Ask for references
- Verify insurance
- Avoid deals that seem “too good to be true”
5. Labour Supply Chain Fraud
What it is:
Fraudulent subcontractors or companies enter the supply chain and disappear without fulfilling obligations.
How it works:
- Fake companies join projects
- Payments flow through multiple entities
- Final company disappears without paying taxes or workers
Warning signs:
- No physical office
- Frequent company changes
- Inconsistent invoices
- Unrealistically low labour costs
These are classic indicators of labour fraud in construction .
How to avoid it:
- Vet all subcontractors
- Keep supply chains simple
- Maintain proper documentation
- Monitor payment flows
6. Payment Redirection Scams
What it is:
Scammers intercept communication and change payment details.
Example:
You receive an email saying:
“We’ve updated our bank details please use this account.”
The email appears legitimate, but the account belongs to a scammer.
Why it works:
- Email accounts may be compromised
- Messages look authentic
- Timing is often perfect
How to avoid it:
- Never rely solely on email for payment changes
- Confirm via phone or in person
- Use secure communication channels
7. Poor Work / Partial Completion Scams
What it is:
A contractor starts work, takes payment, and either:
- Delivers poor-quality work
- Leaves the project unfinished
How it works:
- Initial trust-building
- Partial work completed
- Requests additional payment
- Disappears
How to avoid it:
- Pay in stages
- Inspect work before payment
- Retain final payment until completion
- Use contracts with clear deliverables
Key Signs You’re Being Targeted by a Scam
Watch out for these universal red flags:
- Requests for urgent payment
- Changes in bank details

- Cash-only demands
- Poor communication or missing documents
- Prices significantly below market rate
