Quick answer
How do I handle a customer complaint?
Slow it down, and go back to the facts. Listen, note the problem, check it against what was agreed, and suggest a clear next step. Never argue in a public review, and don't promise anything until you've checked.
The jargon
The words you'll come across, in plain English.
- Complaint: a customer telling you something's wrong with the work or the service.
- Snag: a small thing left to finish or fix at the end of a job.
- Reasonable care and skill: the standard the law says every job must be done to.
- Repeat performance: the customer's right to have poor work put right, at your cost.
- Terms: the written conditions of your agreement with the customer.
- Consumer: a member of the public buying for themselves, not for a business. They have extra legal rights.
Prevent it
How do I stop disputes happening?
Good records protect you both:
- What's included and what isn't, in writing
- A clear price and when they pay
- Changes agreed before extra work
- Honest dates
- Photos and job notes
- A way to sort snags at the end
- How to complain, and what happens next
Responding
What should I do when a customer complains?
The same simple steps every time:
- Acknowledge it.Tell them you've got their message.
- Check.The quote, messages, photos and job notes.
- Clarify.Separate what was agreed from what was assumed.
- Suggest.A sensible next step, with a date.
- Write it down.Confirm what you agreed, in writing.
Let them finish, then repeat the problem back calmly. Check your records before promising anything. If it's safe to, go and have a look.
Don't match anger with anger, share private details, or admit something you haven't checked.
Their rights
What rights does the customer have?
By law, every job for a member of the public must be done with reasonable care and skill. If it wasn't, the customer can ask you to put it right. You do that at your own cost (labour and materials), within a reasonable time and without causing them significant hassle. If that isn't possible, they can ask for money off.
So a complaint about the work usually starts with "come back and fix it", not a refund. Your terms have to be fair, and can't take away these rights. If rights, safety or liability are unclear, get proper legal or trade advice.
Getting help
Where can I get free help with a dispute?
Both you and your customer can get free, independent consumer advice:
- England and Wales: Citizens Advice consumer helpline, 0808 223 1133.
- Scotland: Advice Direct Scotland, 0808 164 6000.
- Northern Ireland: Consumerline, 0300 123 6262.
Your trade body or scheme may also have a complaints or dispute service.
Safety first
What if a customer becomes abusive?
Abuse and threats aren't part of the job. Leave if it's not safe, keep any evidence, and call the police if you need to. Have a plan for working alone, so you're not making it up under pressure.

FAQs
Frequently asked questions.
Should I refund straight away?
Check the facts, the agreement and their rights first. Usually the first step is putting the work right. Replying quickly isn't the same as admitting fault.
Can I refuse to work for them again?
Usually, yes, but finish what you've agreed and never discriminate unlawfully.
What if they post a bad review?
Reply briefly with no private details, keep evidence, and only report it if it breaks the review site's rules.
When should I get legal help?
When the money, safety, liability or threats make sorting it informally risky.
Should I record phone calls?
That raises legal and privacy issues. Usually easier: take notes and send a written summary.
What if they won't let me in to fix it?
Note the appointments you offered and why you need access, explain calmly what happens if not, and get advice before closing it.
