In brief: Construction and the trades consistently report among the worst payment performance of any UK sector, with long payment chains, retentions and applications for payment stacking delay on delay. Direct Debit cannot fix a main contractor's payment run, but for the large slice of trade income that is repeat and agreed, from maintenance contracts to domestic clients on payment plans, it removes the wait entirely.

This guide is about knowing which slice is which, and collecting each properly.

Why construction gets paid worst

The sector's structure works against the smallest firms in the chain. Payment flows from client to main contractor to subcontractor to sub subcontractor, and each link adds approval time, retention deductions and payment run delays. Industry payment data has repeatedly placed construction among the highest late payment rates of any major UK sector, and government research shows small firms across the economy losing an average of 86 hours a year to chasing, with around £26 billion owed at any time.

For a subcontractor, that means the money for completed work routinely arrives 45, 60 or 90 days after the graft, while wages, materials and vehicle costs leave weekly. The full damage is set out in the true cost of late payments.

Split your income into two buckets

The practical move is separating income that follows contract machinery from income that does not.

Bucket one: contract chain work

Applications for payment, valuations, retentions and pay less notices under the Construction Act. Here the leverage is contractual discipline: applications submitted on time and in the required form, payment and final dates diarised, retentions tracked to their release dates, and statutory interest quantified when payment slips. The 2026 late payment reforms, with their move towards capped terms and mandatory interest, strengthen this bucket over time.

Bucket two: direct and repeat work

Maintenance contracts, service agreements, facilities work, landlord and letting agent jobs, domestic customers, and staged payment plans on bigger domestic projects. This income is agreed directly with the payer, which means the collection method is yours to choose. This is the Direct Debit bucket, and for most trades it is bigger than they think.

Where Direct Debit fits the trades

  • Maintenance and service contracts: monthly or quarterly invoices, often variable with callouts. One mandate covers the base fee and the extras, with notice of each amount.
  • Landlords and letting agents: repeat repair invoicing to the same payers every month. Perfect fit: agree the mandate once, collect per invoice thereafter.
  • Staged domestic projects: deposit, stage payments and balance collected on agreed dates under one mandate, so the awkward "can you sort the transfer" conversation at the kitchen table never happens.
  • Small commercial clients: shops, offices and sites you service directly, invoiced monthly, collected on the due date.

The customer keeps advance notice, cancellation rights and the Direct Debit Guarantee, which is a genuinely easy sell: they never have to remember a payment again, and errors are refundable. The mechanics are in how Direct Debit works.

Making it work on site, not just on paper

  1. Put the payment method in the quote. "Invoices are collected by Direct Debit on the due date" as a standard line. Agreement at quote stage costs nothing; retrofitting it later costs a conversation per customer.
  2. Send the mandate link with the contract or booking confirmation, while goodwill is at its peak.
  3. Invoice from your accounting software the day the work completes. Xero, QuickBooks or Sage supply the amount and due date to the collection workflow automatically.
  4. Let variable amounts vary. Callout charges and materials change monthly; the mandate handles it with notice, no new paperwork.
  5. Run the exception list weekly. Failed collections get a call; everything else got collected.

Common trade objections, answered honestly

  • "My customers won't sign up." They already pay their insurance, van lease and phone this way. Framed as convenience with protection, most say yes, especially at the start of the relationship.
  • "My amounts change every month." That is the design case for Direct Debit, not an exception to it. Standing orders cannot do this; mandates can.
  • "Main contractors will never pay by DD." Correct, and this guide does not pretend otherwise. Bucket one runs on contract discipline; bucket two runs on collection. Fix both, separately.
  • "I need money faster than three days." The Bacs cycle is three working days, but collections are scheduled in advance against known due dates, so speed matters less than certainty. Timings are in how long Direct Debit takes.

How NRTH helps trades get paid

NRTH connects the accounting software trades already use to Direct Debit collection: mandate invitations, collections scheduled on invoice due dates, variable amounts with automatic notice, and payments reconciled back to the invoice. For a trade business, the visible change is simple: the van keeps moving, and the money follows the work instead of trailing six weeks behind it.

Frequently asked questions

Can a plumber or electrician use Direct Debit for one off jobs?

Yes. A mandate can collect a single agreed invoice, and staged plans for bigger jobs collect under the same instruction. One off collection is covered in Direct Debit for one off payments.

Does Direct Debit work for CIS subcontractor payments?

Payments from contractors under CIS follow the contractor's payment process, not yours, so they sit in bucket one. Direct Debit applies to income you bill directly to your own customers.

What about retentions?

Retentions are a contract mechanism and remain so. Track them to their release dates and invoice promptly when due; the released amount can then be collected like any invoice where a mandate exists.

Will customers trust a small trade firm with a mandate?

The trust sits with the scheme, not the firm's size. Payers are protected by advance notice and the Direct Debit Guarantee, the same protections behind their utility bills.

The work is done, the van has moved on. The payment should not still be on site.
