What are existing customer betting offers?
Existing customer betting offers are ongoing promotions a bookmaker runs for punters who already hold an account, rather than one-off welcome bonuses. They are how bookmakers reward loyalty and add value to everyday bets. The main types are:
- Price boosts and super boosts — a selection’s odds enhanced above the standard price, usually daily and often with a small maximum stake.
- Acca boosts — a percentage bonus added to winning accumulators, rising with the number of legs.
- Acca insurance — your stake refunded, normally as a free bet up to a cap, if one leg of a qualifying acca lets you down.
- Best Odds Guaranteed (BOG) — take an early price on a horse or greyhound and get paid at the starting price instead if it drifts.
- Money-back specials — your stake returned under set conditions, such as your horse finishing second.
- Free-to-play games — no-stake daily games returning free bets, free spins or cash.
- Loyalty cards and clubs — points or rewards accrued across online and retail betting.
Unlike welcome offers, most of these are available every day and have no expiry, so the value compounds for regular bettors.

Which bookmaker has the best offers for existing customers?
It depends on how you bet. bet365 has the widest everyday programme and the deepest range of free-to-play games. Betfred is strongest for horse racing punters thanks to the Lucky 15 bonus and generous Extra Places. BoyleSports stands out for accumulator and greyhound bettors, being one of the only major books to extend BOG to greyhounds. Ladbrokes and William Hill lead on loyalty schemes with the Grid Card and Plus Card. For app-based rewards that credit automatically, Midnite is the pick.
The smart approach is to hold accounts with two or three books and use whichever runs the best offer for the bet you’re placing that day.
