About British Gas

British Gas supplies domestic gas and electricity and offers an online account for managing the energy relationship. Its account page says customers can view and pay bills, manage Direct Debits and submit meter readings in one place. The same account also supports home-service appointments, but that is separate from an energy switch and from this referral. A prospective customer should therefore treat the referral as an energy-acquisition offer, not as boiler cover, an engineer entitlement or a promise about a particular tariff.

The normal experience starts with a quote for the address and desired fuel arrangement. British Gas says an accurate quote is helped by a recent bill and needs, at minimum, the postcode, house number or name, and a choice of single or dual fuel. The customer chooses a tariff and payment method, British Gas arranges the switch date with the outgoing supplier and later asks for an opening meter reading. The supply should not be physically interrupted by the switch. British Gas says it will email when the customer is on supply; an opening reading is still needed to set up the account and first bill, even where the home has a smart meter. Smart-meter usage may take a few days to appear in the online account or app.

That practical account use matters because the promotion does not replace normal energy administration. Unit rates, standing charges, billing frequency, Direct Debit arrangements, tariff length and the availability of a particular product are matters for the live quote and contract at the property. British Gas offers fixed, variable, smart and other tariffs, but none is promised by the Referral link. A fixed tariff may offer price certainty, while a variable tariff can change; those are tariff decisions rather than a voucher benefit. Keep the quoted tariff documents and the switch confirmation, and submit the requested meter reading promptly so the opening and closing bills can be checked against the same switch date.

Get £100 voucher with British Gas

**Offer recorded for this directory: £100 voucher.** The referral mechanism is a **Referral link**, not a code to type. Use this exact, unshortened destination during the new-customer journey: https://refer.britishgas.co.uk/shahidak-55. Do not substitute a search result, a copied code, a different referrer’s page or a standard British Gas quote page if the referral journey has not confirmed that it is tracking the link.

British Gas’s public Refer a Friend page currently describes the energy reward as £25 for electricity and £25 for gas for each person, and says that a referrer and friend share £100 when the friend switches both gas and electricity. In other words, the directory’s £100 voucher headline should not be assumed to mean that one new energy customer receives £100 personally: the published description points to £50 per person on a qualifying dual-fuel referral. The live referral page and the terms shown at application are the records to use if they display a different amount, voucher brand, product scope or calculation. British Gas’s offers page describes the reward as an online gift voucher and its current additional information refers to an Amazon.co.uk Gift Card; confirm the fulfilment option presented in the exact journey before applying.

The public rules say the referrer must successfully identify as an existing British Gas home-energy customer through an online account. The friend must be an individual the referrer knows personally, must not already be a British Gas customer, and must be willing to receive the referrer’s link. For an energy-switch reward, British Gas additionally says the friend must not have held a British Gas energy contract in the three months before joining. The friend must use the referrer’s unique link when joining British Gas on a qualifying product through britishgas.co.uk. A valid email address is required to receive the gift card.

Qualification is not complete merely because a form is submitted or the meter changes supplier. The friend’s energy contract must remain active for at least 90 days after the supply start date. If the friend cancels after a qualifying purchase but within 90 days of that start date, British Gas says the reward for both friend and referrer is cancelled. British Gas also says the gift-card reward may take up to three months to arrive from the friend joining. Those published clocks do not establish a guaranteed calendar payment date for this particular link, especially where the application, supply start and referral validation occur on different dates. Provider confirmation is needed for the exact fulfilment date, value split, qualifying tariff list, and any circumstances not stated on the live journey.

The voucher is a promotion, not energy credit, a reduction in unit rates, a refund of standing charges, cash, a tariff comparison result or a waiver of debt and exit charges. The customer still pays the agreed British Gas tariff from the supply start date and remains responsible for energy used and standing charges with the old supplier up to that date. Any exit fee charged by an existing supplier, outstanding balance, or restriction arising from an existing contract is separate from this referral and must be checked before switching.

How to claim the offer

1. 1Open the exact Referral link — https://refer.britishgas.co.uk/shahidak-55 — before obtaining the quote. Check that the browser is on a British Gas referral journey and retain a dated screenshot of the reward wording, qualifying-product language and terms shown. If a consent wall, error or standard quote page prevents that confirmation, do not assume the referral has tracked; ask British Gas to confirm the journey before completing an application.
2. 2Gather a recent energy bill and confirm the supply address, postcode, current gas and electricity arrangement, meter type, current supplier and payment method. This improves the quote and makes it possible to compare the live British Gas unit rates and standing charges with the existing arrangement. The voucher should not be used as a substitute for that comparison.
3. 3Check the outgoing supplier’s contract before proceeding. In particular, check whether it is fixed, its end date, any exit charge, the balance on the account and the consequences of leaving. British Gas says a switch itself should not cost anything, but a fixed deal with the previous supplier can have an exit fee outside the final 49 days. That fee is not covered by the referral voucher.
4. 4Continue from the referral journey to a British Gas quote, choose only a tariff that the live page identifies as a qualifying product, and review the tariff and contract documents before accepting. Do not infer that every British Gas tariff, a boiler product, a single-fuel quote, a prepayment arrangement or a tariff offered after the referral click is eligible. Obtain provider confirmation if the journey does not state it clearly.
5. 5Enter the correct applicant, property and contact details, including an email address that can receive the reward. The referrer must be able to identify as an existing British Gas home-energy customer through an online account; the applicant should confirm with the referrer that this has been done. The referred customer should also check that they have not held a British Gas energy contract in the preceding three months.
6. 6Before confirming, save the quote, the chosen tariff name, unit rates, standing charges, payment method, contract term, start-date estimate, cancellation information and referral evidence. Check both gas and electricity if relying on the £100 shared dual-fuel description. British Gas’s normal switch process also gives a 14-day cooling-off period; do not waive it simply for a promotional expectation without deciding whether an earlier switch suits the household.
7. 7Watch for British Gas’s tariff and switch-date confirmations. British Gas says it contacts the existing supplier and that the customer does not normally need to tell that supplier they are leaving. Continue paying the old supplier for usage and standing charges up to the switch date, then check its final bill and any credit refund independently of the referral.
8. 8When British Gas asks for an opening meter reading, provide it promptly and keep a dated photograph or record. British Gas says it needs an opening reading even with a smart meter so it can set up the account and first bill accurately. The outgoing supplier may also request a final reading, so retain the same evidence until both bills are settled.
9. 9Set up and use the British Gas online account to review the first bill, payment arrangement and meter information. British Gas says the first bill should usually be ready within a month of switching unless quarterly billing is chosen. If usage data from a smart meter is slow to appear in the account or app, that does not by itself prove the supply switch or referral has failed.
10. 10Keep the qualifying British Gas energy contract active through at least 90 days after supply start. Monitor the reward email address, including spam and junk folders, for up to the provider’s stated three-month arrival window. If no reward is received after the applicable window, contact British Gas with the exact link, application and supply-start dates, tariff confirmation, email address and saved referral evidence; do not cancel the energy contract on the assumption that a missing voucher has been automatically approved.

Your referral benefit

The benefit recorded here is a **£100 voucher** attached to a British Gas Referral link. The current official energy-referral description makes the important distinction that the £100 is described as shared across referrer and friend where the friend switches both gas and electricity: British Gas says each gets £25 for gas and £25 for electricity. The practical reading is therefore £50 for the referrer and £50 for the referred customer on a qualifying dual-fuel switch, rather than an automatic £100 payable to one household. The exact landing-page presentation and terms at the time of application should be checked because this is the specific referral route being recorded.

It is an online gift-voucher promotion, not money deducted from the energy bill. It does not set or cap the tariff’s unit prices, remove standing charges, pay an old supplier’s exit fee, clear a balance, guarantee a lower bill, change the meter, or alter switching rights. British Gas’s current additional information names an Amazon.co.uk Gift Card for the Refer a Friend reward, while its broader referral page refers to online vouchers; neither statement should be expanded into an unsupported promise about cash alternatives, transferability, redemption conditions or a particular voucher brand for this exact link. Read the voucher terms and the live referral journey before relying on the reward.

The reward is conditional. The friend must come through the unique link to a qualifying product, meet the new-to-British-Gas condition, have a valid email address and keep the supply contract active for at least 90 days from supply start. A cancellation within that period cancels the reward for both people. British Gas says fulfilment may take up to three months from the friend joining, so it is not an instant sign-up incentive. The opportunity to receive the voucher should be weighed against the actual tariff quote and all normal household energy costs.

Before you claim

• Confirm that the exact address in the browser is https://refer.britishgas.co.uk/shahidak-55 and that the page is a British Gas referral journey before beginning the quote. Keep a timestamped screenshot; a generic quote page cannot prove referral tracking.
• Check whether the live journey calls the chosen product a qualifying product and whether it expressly covers both gas and electricity. The public page associates the shared £100 with a dual-fuel switch, so do not presume that a single-fuel application has the same total value.
• Ask the referrer to confirm that they are an existing British Gas home-energy customer and can identify through their online account. The referrer’s customer status and account identification are published eligibility conditions, not optional administrative details.
• Confirm that the referred applicant is an individual known personally by the referrer, is not already a British Gas customer and has not held a British Gas energy contract within the last three months. Where a previous account, a move, a joint account or a name change makes this unclear, seek British Gas confirmation before applying.
• Read the displayed reward terms for the exact voucher brand, amount attributed to each person, qualifying tariff or product, 90-day retention requirement, email requirement and fulfilment date. British Gas’s public pages give the overall structure, but the exact referral landing page must confirm the campaign variant.
• Compare the quote’s unit rates, standing charges, estimated usage assumptions, tariff type, tariff duration, payment method, billing frequency and any exit fee with the current supplier. A voucher is not a tariff discount and should not be netted off against projected bills without making the underlying comparison.
• Check the old supplier’s final-bill position: whether a fixed tariff has an exit fee, whether there is credit to be refunded, and whether a balance is owed. British Gas says the outgoing supplier is paid for usage and standing charges until the switch date; the referral does not change that liability.
• Check the switch confirmation and cooling-off information. British Gas describes a 14-day cooling-off period and says a switch can be completed in as little as three to five days if it is waived. Treat these as normal switching information, not a promise that the referral will pay sooner.
• Provide and retain opening and final meter readings around the switch date, even if there is a smart meter. Verify the first British Gas bill and the outgoing supplier’s closing bill against those readings, then preserve the records through the 90-day qualification period and expected reward window.
• Check the valid email inbox and junk folder for the reward only after the relevant timing conditions have passed. If it has not arrived, present British Gas with the link, screenshots, supply date and account evidence rather than relying on an unrecorded verbal promise.
