Electrician Customer Not Paying? Here's Exactly What to Do

Why Customers Don't Pay (and Why It Matters for Your Approach)

Before sending a strongly-worded email, understand the reason. It changes your opening move.

• Forgotten or lost invoice — the most common cause, especially for domestic customers. A single automated reminder fixes this 60–70% of the time.
• Cash flow problem — the customer intends to pay but genuinely can't right now. A payment plan gets you paid faster than a dispute.
• Dispute about the work — real or manufactured. Needs to be addressed in writing before you escalate.
• Deliberate avoidance — rare, but real. Requires the full legal process below.

Your tone at step one should assume category one. Only escalate the language once you have evidence of intent to avoid.

What UK Law Says About Late Payment

You are not chasing as a favour. You have statutory rights.

Domestic customers (consumer jobs)

Payment is due 30 days after the invoice date unless your written terms specify otherwise. Under the Consumer Rights Act 2015, your contract terms must be fair and transparent — if you had no written terms, a court will imply reasonable payment within a reasonable time, which is typically interpreted as 14–30 days.

Business-to-business jobs

The Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge:

• Statutory interest at 8% above the Bank of England base rate from the day the debt becomes overdue
• A fixed debt recovery charge of £40 (invoices up to £999), £70 (£1,000–£9,999), or £100 (£10,000+)
• Reasonable recovery costs (e.g. solicitor letters) on top

You do not need to have mentioned this in your original invoice — it is a statutory right. Adding it to a chaser letter is often enough to prompt immediate payment from a business customer.

Practical example: You complete a £2,400 rewire for a landlord. Invoice issued 15 January, payment due 14 February. By 15 March — 29 days overdue — you are entitled to £2,400 × (8% + current base rate) pro-rated, plus the £70 fixed recovery charge. Mention this in your chaser. Most landlords pay by return.

The 4-Step Escalation Process

Step 1 — Friendly reminder (day 1–7 overdue)

Send by email and, if you have it, WhatsApp or SMS. Keep the tone light — assume the invoice was lost.

Template:

Hi [Name], just a quick note — invoice [number] for £[amount] appears to be outstanding. Could be lost in spam! Payment details are below. Let me know if you have any questions. Thanks, [Your name]

Include a direct payment link (bank transfer details or a payment page). Friction kills conversion — make it as easy as possible to pay right now.

Step 2 — Formal chaser (day 8–21 overdue)

Tone shifts to professional but firm. Reference the due date explicitly.

Template:

Dear [Name], invoice [number] for £[amount] was due on [date] and remains unpaid. Please arrange payment within 7 days. If you are experiencing difficulty, please contact me to discuss. If you are a business customer, please note that statutory interest under the Late Payment of Commercial Debts Act will begin to accrue from [date]. Payment details: [details].

Step 3 — Letter Before Action (day 22–35 overdue)

This is a formal legal step. Send by recorded post and email. Keep a copy. This letter is required before you can file a Small Claims Court claim, and it frequently resolves the debt on its own — people take it seriously when they see "Letter Before Action" in the subject line.

What to include:

• Full invoice details (number, date, amount, work description)
• Date payment was due
• Total now owed including any statutory interest and recovery charges
• A 14-day deadline to pay or contact you to agree a payment plan
• Statement that failure to respond will result in a county court claim without further notice
• Your full name, address, and contact details

You can find free Letter Before Action templates from Citizens Advice and the government's Pre-Action Protocol guidance.

Step 4 — Small Claims Court

If the Letter Before Action is ignored, file online at Money Claim Online (MCOL) at gov.uk. The process is designed to be used without a solicitor.

• Claims up to £10,000 in England and Wales (£5,000 in Scotland via Simple Procedure)
• Court fees: £35 for claims up to £300, up to £455 for claims up to £10,000 — recoverable if you win
• Most defendants pay within 14 days of receiving the claim form, before any hearing
• If they don't respond, apply for a default judgment — typically granted within weeks
• With a judgment, you can instruct bailiffs (High Court Enforcement Officers for larger amounts) or apply for an attachment of earnings order

The court process sounds intimidating. In practice, for a straightforward unpaid invoice with a signed job sheet and a paper trail, it is methodical and usually successful.

What If the Customer Claims the Work Was Faulty?

This is the most common tactic used to avoid payment. Handle it systematically, not emotionally.

1. Ask for the complaint in writing — "Please email me the specific issues you'd like addressed." Vague verbal complaints have no legal standing.
2. Inspect and document — attend, photograph, and note your findings in writing the same day.
3. Separate valid snags from full invoice disputes — a minor snag does not entitle a customer to withhold the entire invoice. Courts apply proportionality: a £150 snag on a £3,000 job may reduce the award by £150, not void the invoice.
4. If the complaint is genuine — fix it, get the customer to confirm in writing that the work is now complete, then issue a final invoice for the balance.
5. If the complaint is a delaying tactic — document your position, proceed with the Letter Before Action, and attach your evidence bundle (photos, job sheets, correspondence).

If you are NICEIC or NAPIT registered, your trade body can provide dispute support and their involvement often prompts resolution without court.

The Real Problem: Most Electricians Chase Too Late and Too Manually

The research is clear: invoices unpaid after 90 days have a recovery rate below 25%. After 6 months, below 10%. The window closes fast.

The other reality: most electricians chase invoices inconsistently because it is uncomfortable and time-consuming. One reminder gets sent. Then a week passes. Then another. Then it has been two months and the customer has learned that ignoring you works.

Automated invoice chasing removes the human hesitation. The system sends reminder one on day 3, reminder two on day 10, the formal chaser on day 21 — every time, without you having to remember, without the awkwardness of deciding whether to chase. The customer experience is professional. Your cash flow is protected.

Prevention: How to Avoid Non-Payment Before It Happens

The best debt recovery strategy is avoiding the debt in the first place.

Deposits

For jobs over £500, take a 25–50% deposit upfront. It is standard practice, filters out bad-faith customers, and means you are never fully exposed. Frame it as materials procurement: "I'll order the materials once the deposit clears — that keeps your job slot."

Stage payments on larger jobs

For rewires, new builds, or commercial fit-outs: first fix payment, second fix payment, final completion payment. Never complete second fix work on an unpaid first fix invoice.

Signed job sheets

Get the customer to sign a completion sheet on the day. "I just need your signature to confirm the work is done to your satisfaction." This eliminates retrospective workmanship complaints and is powerful evidence in court.

Clear written terms

Even a short paragraph at the bottom of your quote: payment due within 14 days of invoice, late payment subject to statutory interest, ownership of materials remains with [your company] until full payment received. Courts respect written terms.

Credit checks for large B2B jobs

For commercial jobs over £5,000, a basic credit check via Companies House or Experian costs under £10 and takes minutes. A company with CCJs against it is a payment risk before you start.

Debt Collection Agencies: When to Use One

A debt collection agency is worth considering when:

• The debt is under £500 (Small Claims is viable but the time cost may not be worth it)
• You cannot locate the debtor's current address for court papers
• You have a CCJ but the debtor has ignored it

Reputable UK agencies work on a no-collection-no-fee basis, typically taking 15–25% of the recovered amount. They have tools (tracing, credit bureau reporting) that individual trades businesses do not. The Trade Credit Insurance Association and the Credit Services Association maintain directories of regulated agencies.

Avoid agencies that charge large upfront fees — no legitimate agency needs payment before they have recovered anything.

A Word on Removing Work or Cutting Power

Do not do it. Removing installed materials or disconnecting a supply as a debt recovery mechanism is illegal in the UK — it can constitute criminal damage, and for anything touching the electricity supply, you risk breaching the Electricity at Work Regulations 1989. The internet is full of forum posts where electricians have done this and regretted it. It hands the moral high ground to the debtor and potentially gives them a counterclaim against you. Use the legal process.

Your Evidence Bundle — What to Prepare Before Any Legal Step

Before sending a Letter Before Action or filing a court claim, gather:

• Signed quote or contract
• Invoice with issue date and due date clearly marked
• Proof of delivery (email read receipt, WhatsApp blue ticks, or recorded post receipt)
• Signed job completion sheet (if you have one)
• Photos of completed work
• All correspondence — emails, texts, WhatsApp messages, notes of phone calls with dates and times
• Any previous chasers you have sent

Print and date everything. Courts like clear bundles. You do not need a solicitor if your evidence is organised.

Frequently Asked Questions

How long before an electrician invoice is legally overdue in the UK?

For domestic (consumer) jobs, 30 days after the invoice date unless different terms were agreed in writing. For business-to-business jobs, the Late Payment of Commercial Debts (Interest) Act 1998 sets the default at 30 days. After this point you can charge statutory interest at 8% above the Bank of England base rate, plus a fixed recovery charge of £40–£100 depending on invoice size.

Can an electrician take a customer to court for not paying?

Yes. In England and Wales, use the Small Claims Court (Money Claim Online) for debts up to £10,000. Court fees range from £35 to £455 and are added to the claim if you win. Most debtors pay before the hearing once they receive the formal claim. In Scotland use the Simple Procedure for claims up to £5,000.

What can I do if a customer refuses to pay claiming poor workmanship?

Request the specific complaint in writing immediately. If a genuine snag exists, fix it and issue a final invoice. If the complaint is disproportionate or fabricated, document your completed work with photos and correspondence, then proceed with a formal Letter Before Action and, if needed, a Small Claims Court claim. Courts do not allow a minor snag to justify withholding an entire invoice.
