GDPR worries a lot of tradespeople. Some have even stopped keeping proper customer records because they’re not sure if it’s allowed.
Here’s the truth: GDPR doesn’t stop you keeping a list of your customers to follow up with. It just means being sensible about how you hold and use their details.
For the specific question of whether it’s legal to keep chasing a quote, see our guide on is it legal to keep chasing a quote — this one covers the data side: what you can hold, for how long, and what to do if someone asks you to delete it.
What GDPR Actually Says (In Plain English)
GDPR (and the UK’s Data Protection Act 2018) says you need a lawful basis to hold and use someone’s personal details. For a tradesperson, the relevant basis is usually straightforward:
- If someone asked you for a quote, holding their name, number, and details of the job to respond to that request and follow up on it is a legitimate, expected use of their information.
- You don’t need a signed consent form to keep a customer’s number so you can chase the quote they asked for.
What You CAN Do
- Keep a list of customer names, numbers, and job details for quotes you’ve given
- Follow up on a quote by phone or text
- Keep past customers’ details so you can check in about future work
- Ask a happy customer if they’d refer you to someone else
Just remember: this covers using their details for what they’d reasonably expect — following up on the specific quote or job. It doesn’t cover using their number for unrelated marketing without asking first.
What You CANNOT Do
- Buy or acquire lists of people who never contacted you and start texting or calling them about your services
- Ignore a request to stop — if someone asks you not to contact them again, you must stop
- Hold onto details indefinitely with no reason — if you’ve got no realistic prospect of ever working with someone again, their details shouldn’t sit in your system forever
- Use a past customer’s number for something unrelated without asking — e.g. adding them to a general marketing list for services they never asked about
- Hide who you are — always be clear about who’s contacting them and why
Practical Steps for a Tradesperson
1. Know Where Your Customer List Came From
For everyone in your system, you should be able to say: “Where did I get their details, and why do I have them?” For most tradespeople, the honest answer is simply “they contacted me for a quote” — which is a perfectly good answer.
2. Keep It Simple and Organised
A basic note against each customer of when you last spoke and what was discussed is enough — you don’t need anything more formal than that.
3. Respond If Someone Asks What You Hold
If a customer asks what details you have on them, you should be able to tell them — a name, number, and notes on the job is usually all it is, so this is easy to answer honestly.
4. Have a Simple Privacy Note on Your Website
If you take enquiries through a website or booking form, a short, honest privacy note explaining you keep their details to respond to enquiries and follow up on quotes is enough. It doesn’t need to be written by a solicitor.
5. Delete Details When Asked
If someone asks you to delete their information, do it, and remove them from wherever you keep your customer list.
The Biggest Myth
“GDPR means I can’t keep customer details or call people back.”
False. GDPR means being sensible, transparent, and only using details for what people would reasonably expect. It doesn’t stop you doing normal trade work — quoting jobs, following up, and keeping in touch with past customers.
The tradespeople who run into trouble are the ones buying marketing lists of strangers and blasting them with unsolicited texts — not the ones following up on a quote someone actually asked for.
A Simple Checklist
Before holding onto someone’s details, ask yourself:
- Did they contact me, or did I acquire their details some other way?
- Am I only using their details for what they’d reasonably expect (the job, the quote, future similar work)?
- Would I respect it if they asked me to stop contacting them?
- Could I explain simply what I hold on them and why?
If the answer to all four is yes, you’re almost certainly fine. Get back to chasing that quote.
