This guide covers British Gas customer service numbers, emergency contacts, online account support, complaints and advice for homeowners, tenants and landlords.

British Gas Contact Numbers

These are commonly published contact numbers, but British Gas may direct different account types to different teams. Check your latest bill or official British Gas account for the most appropriate number and current opening hours.

What Is the British Gas Customer Service Number?

The commonly listed British Gas customer service number for domestic gas and electricity enquiries is 0333 202 9802.

Customers may use the service for assistance with billing, account details, payment arrangements, meter readings and other energy-related questions.

Before calling, it is useful to have your customer account number, property address and recent bill available.

British Gas may offer alternative contact routes for particular account types, including online messaging and account-specific support.

British Gas Customer Service Opening Hours

British Gas customer service opening hours can vary according to the department and type of enquiry.

General energy account support may have different operating hours from HomeCare, repair services and emergency assistance.

Customers should check the latest opening times through their British Gas account or official contact information.

Emergency gas and electricity services operate separately from routine customer support.

British Gas Emergency Contact Number

If you suspect a gas leak, the correct number in Great Britain is the National Gas Emergency Service: 0800 111 999.

This service is available 24 hours a day, seven days a week.

It is not necessary to be a British Gas customer to use this emergency number.

If you smell gas, open doors and windows where safe, avoid using electrical switches or naked flames, and leave the property if necessary.

Call the emergency service from a safe location.

If there is immediate danger, call 999.

British Gas Power Cut Contact Number

If your electricity supply stops because of a network fault, call 105.

The 105 service connects callers to the relevant electricity network operator in Great Britain.

Your electricity network operator is responsible for the local distribution infrastructure.

British Gas, as your energy supplier, handles your account and energy charges but does not directly control every part of the electricity network.

If a power cut affects only your property, check whether the problem relates to your consumer unit, meter or account before contacting the appropriate service.

British Gas HomeCare Contact Number

For British Gas HomeCare enquiries, boiler breakdowns and home services support, call 0333 200 8899.

British Gas lists its breakdowns and enquiries service as available 24 hours a day, seven days a week.

HomeCare customers can also use their online account to arrange eligible engineer appointments, check cover details and manage certain services

British Gas Boiler Repair Contact Number

If your boiler is not working, the correct contact route depends on whether you have HomeCare cover.

Existing HomeCare customers can use 0333 200 8899.

For one-off repairs without HomeCare cover, British Gas lists 0333 202 9799.

Before booking an engineer, check whether the issue relates to the thermostat, heating controls or an interruption to the electricity supply. Do not remove boiler covers or attempt gas repairs yourself.

British Gas Annual Boiler Service Number

For annual boiler service appointments, British Gas lists 0330 100 0079.

The published telephone hours are Monday to Friday, 8am to 8pm, and Saturday, 8am to 6pm.

HomeCare customers may also be able to book their annual service through their online account or the British Gas app.

British Gas HomeCare Cancellation Number

Customers wishing to cancel an existing HomeCare agreement can call 0333 202 9343.

British Gas also provides online cancellation options.

Cancellation charges may apply depending on the agreement, the date of cancellation and whether services have already been provided.

Simply cancelling a Direct Debit does not automatically cancel a HomeCare agreement.

British Gas Contact Number for Payment Difficulties

Customers struggling to pay their energy bills can contact British Gas on 0330 808 3880.

British Gas publishes the following hours for this service: Monday to Friday, 8am to 6pm, and Saturday, 9am to 2pm.

Customers may be able to discuss affordable repayment arrangements or other appropriate support.

Contacting the supplier before arrears increase can make it easier to explore available options.

British Gas Billing Enquiries

If you believe your British Gas bill is incorrect, check the meter readings, billing period and tariff details.

An unexpectedly high bill may result from increased energy consumption, estimated readings, tariff changes or a previous underpayment.

Customers should compare the opening and closing meter readings against their actual meter.

When contacting British Gas, explain the discrepancy and ask for the bill to be reviewed.
