Out-of-hours and emergency contact details online

Key takeaways

If you offer an emergency or out-of-hours service, show the number prominently with the hours it covers, typical response times, the area and any call-out charge. If you do not, say so and point to who can help, such as a gas emergency line. Unclear emergency information costs trust when customers need you most.

• Show the emergency number with hours, area and response time.
• State the call-out charge before people call.
• If you do not cover emergencies, say who does.
• Only promise 24/7 cover you actually provide.

Should your website show an emergency contact number?

Yes, if you provide an emergency or out-of-hours service. Show the number where a panicking customer will see it first, usually the header on mobile, with the hours, area, typical response time and charges. Global Bridge Labs (GBL) sees emergency details drive urgent calls for trades, IT support and property services.

• What information should every business website have?
• Click-to-call: turn mobile visitors into phone calls
• Mobile websites for tradespeople: win the urgent job

What details should go with the number?

Give the hours covered, the area, what counts as an emergency, the typical response time and the call-out charge or price guidance. Customers in a crisis are vulnerable to surprise bills, so stating charges up front builds trust and reduces disputes.

• Publish your service levels on your website
• Prices with or without VAT: what your website shows

What if you do not offer emergency cover?

Say so clearly, and point to who can help. For example, a heating engineer might link to the national gas emergency number for a suspected leak. This avoids customers waiting for a reply that will not come and shows you care about their safety.

• What a gas engineer's website must show

How do you avoid over-promising?

Only advertise '24/7' if someone really answers at 3am on a bank holiday. If cover is limited, describe it exactly: 'Emergency line 7am to 10pm, seven days'. The CMA's guidance on unfair commercial practices covers misleading claims about service availability.

• Inaccurate information on your website: the legal risk

Where should emergency details appear?

Put the emergency number in the mobile header, on the contact page, on relevant service pages and on your Google Business Profile. Keep the hours consistent everywhere. Add it to your voicemail message and out-of-office email replies.

• Holiday and seasonal opening hours on your website

When should emergency details stay low-key?

Keep them low-key when emergencies are a small part of your work and you do not want to attract only urgent jobs. A line on the contact page for existing customers may be enough. Make it prominent only if you want and can handle that work.

What does this look like in practice?

A pattern we see in trades: '24-hour emergency service' appears in the footer, but evening calls go to voicemail. Rewriting it to state the real hours and the call-out charge sets honest expectations, and the calls that arrive are from customers who accept the terms.
