Six key facts, one pattern: British Gas offers two free 0800 lines — one for everyday customer service and one for emergencies — with different hours of operation depending on the department.

Free phone number for British Gas

What is the British Gas 0800 number?

• The main free customer service number is 0800 800 150. It’s listed on the official British Gas contact page (British Gas Contact us – official customer service page).
• If you suspect a gas leak or smell gas, call 0800 111 999 — the National Gas Emergency Helpline (British Gas Emergencies – safety guidance).
• For power cuts, dial 105 (free from landline and mobile) (Information Now – British Gas contact details).

Is the 0333 number free?

British Gas also uses 0333 numbers (e.g., 0333 202 9885 for gas/electricity advisors and 0330 808 3880 for payment support) (British Gas cool-off information page). While 03 numbers cost the same as calling a geographic number from a landline, they are not always free from mobile phones — depending on your plan. The 0800 numbers are free from all UK mobiles and landlines, making them the safest option to avoid charges.

How to call British Gas for free from mobile?

Simply dial 0800 800 150. This number is free from any UK mobile (including EE, Vodafone, O2, Three, and all MVNOs). There is no additional trick — it’s the standard freephone prefix. For emergencies, 0800 111 999 is also free (Information Now – emergency helpline note).

The implication: sticking with the 0800 prefix is the simplest way to avoid unexpected charges on mobile tariffs.

British Gas live chat

How to start a live chat with British Gas?

• Visit British Gas contact page during business hours. Look for the “Chat” icon — it will be active when advisors are available.
• You’ll need your account number and postcode handy for verification.

What are the live chat hours?

British Gas does not publish explicit live chat hours, but based on customer service opening times (Mon-Fri 8am-6pm, Sat 8am-4pm), it’s reasonable to expect chat to be available during those windows. For urgent issues, call the phone line instead.

Can I use live chat for emergencies?

No. For gas leaks, carbon monoxide fumes, or any immediate danger, you must call 0800 111 999. Live chat should only be used for non-urgent queries such as billing, account changes, or general advice (British Gas Emergencies page).

How can I contact British Gas and speak to a person?

Which number should I call to speak to a representative?

Dial 0800 800 150 during opening hours. You’ll be greeted by an automated system, but pressing the appropriate options will route you to a human agent. Calling early in the day (just after 8am) often reduces wait times.

Is there a way to skip automated menu?

British Gas does not advertise a shortcut to bypass the IVR. However, calling during non-peak hours (mid-morning, mid-week) increases your chances of a quick connection. Some customers report that saying “agent” or pressing 0 repeatedly may work, but this is not official.

What options are available after calling?

1. Call 0800 800 150.
2. Listen to the menu options (e.g., “billing”, “emergency”, “home services”).
3. Select the option that matches your query — for general customer service, choose “account or billing”.
4. You’ll be connected to an advisor or placed in a queue.

For payment difficulties, call 0330 808 3880 (Mon-Fri 8am-6pm, Sat 9am-2pm) (British Gas struggling-to-pay support page).

The pattern: mid-week afternoon calls tend to avoid the longest waits, so schedule accordingly.

British Gas opening times

What are the standard customer service opening hours?

• Monday to Friday: 8am – 6pm
• Saturday: 8am – 4pm
• Sunday: Closed (no published hours on official site)

These hours apply to the main customer service line (British Gas struggling-to-pay team – confirmed opening times).

Are there weekend hours?

Yes, Saturday 8am-4pm. Sunday is generally closed, though the gas emergency line (0800 111 999) operates 24/7, including weekends and bank holidays.

What about bank holidays?

British Gas does not publish a standard bank holiday schedule. Call the customer service line on the nearest weekday before the holiday, or use the emergency numbers if needed. The gas emergency helpline remains open 24/7 every day of the year.

British Gas customer service email

What is the British Gas email address for customer service?

British Gas does not provide a direct email address for general customer service. Instead, they offer an online contact form on their website (British Gas contact page). You fill in your details, account number, and message, and they respond via email.

How to contact British Gas by email?

1. Go to the official contact page.
2. Choose the relevant topic (e.g., “Bills and payments”, “Home services”).
3. Complete the form with your name, account number, and a clear description.
4. Submit and wait for a response — typically within 2 to 5 working days.

What response time can I expect?

British Gas aims to reply within 2-5 working days. For time-sensitive issues (e.g., payment deadlines, service interruptions), phone or live chat are far more reliable. Email is best for non-urgent account queries or documentation requests.

For UK households and businesses, the takeaway is clear: use 0800 numbers whenever possible to avoid call costs, and keep the emergency helpline saved in your phone. British Gas’s contact structure is straightforward once you separate everyday support from urgent safety lines. The company has not changed these numbers in years, and they remain reliable across all major networks. If you need account help, plan your call during weekday mornings — you’ll get through faster than on Monday afternoons.
