Can I Take Any Other Services From British Gas?

In addition to energy, there’s a great selection of services on offer from British Gas. There are varying tiers of homecare boiling and heating cover, plumbing and drains cover and home electrical cover all of which allow you to choose how much excess you pay.

If you don’t have homecare, you can still book a one-off repair for your heating, plumbing and electrics. Those who are thinking about giving their home a more energy-efficient overhaul can purchase a new boiler and take advantage of British Gas’s improvement service.

An engineer will come out for a free consultation and give you a quote for devices like water softeners, system filters and combi save valves to help you get the best out of your home. Cover, repair and home insurance is also available for landlords along with buildings and contents insurance for homeowners.

Does British Gas Offer Smart Meters?

Both standard and prepayment energy customers can get a smart meter installed with British Gas. These devices are free and can help you to cut the cost of your energy bills. They automatically send your meter readings off so you no longer have to rely on estimated bills and the accompanying digital display helps you see where your usage is highest so you know where to make changes.


British Gas is installing the type of smart meter known as SMETS 2, which doesn’t lose its functionality if you switch to another provider, but in the rare circumstances where this isn’t possible, you will receive an SMETS 1 meter. If you do have an SMETS 1 meter, the current aim is to have them all fixed by the end of 2021.

Does British Gas Offer The Warm Home Discount?

Eligible customers will have a one-off payment of £140 credited to their electricity account between March and October. If you’re on a prepayment tariff, you’ll receive a top voucher with the value of £140 during the same period.


Should I Switch to British Gas?

Although it’s only got one green deal, the fact it boasts 100% renewable electricity and offsets 94% of your gas is impressive.
