Frequently Asked Questions
Which utility sign-up bonus is worth the most?
Broadband deals often offer the highest bonuses (£50-£100+ in reward cards or cashback), followed by energy suppliers (£50-£100 account credit). Mobile offers vary widely. Always compare the total deal value, not just the bonus.
How long does it take to receive utility sign-up bonuses?
Typically 30-90 days after completing requirements. Energy account credits usually appear after your first bill. Cashback from sites like TopCashback can take 2-4 months to become payable. Reward cards from broadband providers often arrive within 45 days.
Can I stack cashback with a sign-up offer?
Sometimes. Cashback sites often work alongside provider sign-up bonuses. However, referral links typically can't be combined with cashback tracking. Check the terms of both offers - if in doubt, go with whichever is worth more.
Do I pay tax on utility sign-up bonuses?
No. Sign-up bonuses are incentives for becoming a customer, not taxable income. This is different from refer-a-friend bonuses, where you're earning money for bringing in new customers - those count towards the £1,000 trading allowance.
What if I'm already a customer?
Most sign-up offers are for new customers only. Some providers consider you "new" if you haven't been a customer for 12 months. Check the specific terms. Existing customers can sometimes benefit from loyalty offers or refer-a-friend schemes instead.
Is it worth switching just for a sign-up bonus?
Only if the underlying deal is competitive. A £50 bonus is wiped out if you're paying £100 more per year. Compare tariffs properly, factor in any exit fees from your current provider, and treat the bonus as a nice extra rather than the main reason to switch.
