Best Summer Hotel Deals UK 2026: Expedia & Hotels.com Sales Explained

Summer 2026 brings two of the biggest hotel sales of the year from the Expedia Group brands. Expedia is running its Big Summer Sale from 3 June to 13 July 2026, and Hotels.com is running the Bellboy's Summer Sale from 4 June to 13 July 2026. Both offer up to 40% off select hotels and homes, with stays valid through 15 December 2026 — covering summer holidays, autumn half-term, and early winter city breaks.

Below is a practical breakdown of both sales: what the discounts actually look like, which destinations and property types tend to be most heavily discounted, and the booking workflow that consistently surfaces the best rate.

Expedia Big Summer Sale: 3 June - 13 July 2026

Expedia's sale covers select hotels and homes worldwide, with headline discounts of up to 40% off. In practice, the deepest discounts tend to appear on mid-range chain hotels (3-4 star Marriott, Hilton, IHG properties) in major cities and popular holiday destinations. UK city breaks, Mediterranean resorts, and US cities typically see the widest selection of discounted properties.

The "up to 40%" figure applies to the best-case properties. Across the broader sale inventory, expect discounts of 15-30% on most participating hotels. Expedia's "Insider Deals" (available with a free account) stack on top of the sale pricing, which can push the effective discount higher. One Key members earning 2% back as OneKeyCash get an additional layer of return.

Hotels.com Bellboy's Summer Sale: 4 June - 13 July 2026

Hotels.com's sale starts one day later and runs to the same end date. The format is similar — up to 40% off select hotels — but the discounted properties are not identical to Expedia's, even though both brands sit under the same parent company. Hotels.com tends to discount European city-break properties more aggressively, while Expedia leans harder into UK and US chain hotels.

Hotels.com's "Secret Prices" (available via the mobile app) can further reduce rates beyond the headline sale discount. If you are booking a European trip especially, Hotels.com is worth checking alongside Expedia — the price gap between the two platforms on the same property can widen during sale periods as each brand applies its own promotional discounts.

Key dates and booking rules

• Expedia Big Summer Sale: book between 3 June and 13 July 2026.
• Hotels.com Bellboy's Summer Sale: book between 4 June and 13 July 2026.
• Stay dates: all bookings must be completed by 15 December 2026.
• Your affiliate commission on eligible bookings does not change during these promotions — the discount comes from the platform, not your margin.

How to get the best rate during the sales

1. Compare both Expedia and Hotels.com for the same property and dates — the discounted rate often differs between the two platforms.
2. Log in to both platforms before searching. Expedia's Insider Deals and Hotels.com's Secret Prices require an account or the mobile app and stack with sale pricing.
3. Check the "total stay" figure, not the per-night headline. Taxes, fees, and resort charges are added at the booking summary on both platforms.
4. Prefer free-cancellation rates where available. If the price drops further during the sale window, cancel and rebook at the lower rate.
5. Stack cashback via TopCashback or Quidco (typically 2-4% on hotel bookings) for an additional effective discount on top of the sale price.

Which destinations benefit most?

Based on previous Expedia Group summer sales, the deepest discounts tend to cluster around popular but competitive destinations where hotels have inventory to fill: Spanish and Greek islands, Portuguese coast, Italian lakes, Turkish riviera, and UK seaside towns. Major city hotels (London, Paris, Barcelona, Amsterdam) participate but with smaller discounts — typically 10-20% rather than the full 40% — because occupancy rates are already high in summer.

For autumn and early winter stays (September through December), the discounts can be especially strong because hotels are discounting future low-season inventory. Booking a November city break during a June sale combines the seasonal pricing advantage with the promotional discount — this is where the biggest savings typically land.

What about Booking.com?

Booking.com typically runs its own summer campaign on a similar timeline, often branded as "Summer Getaway Deals." The discounts are comparable (20-40% on select properties), and the participating hotels overlap partially with the Expedia Group sales. For a thorough comparison, check all three platforms during the sale window — the cheapest rate for your specific property and dates will vary.

The bottom line

The Expedia and Hotels.com summer sales are genuine opportunities to save on hotel bookings for trips through December 2026. The headline "up to 40% off" is real but applies to select properties — expect 15-30% on most participating hotels, which is still a meaningful saving on a multi-night stay. The key is to compare both platforms, log in for member-exclusive pricing, prefer flexible cancellation rates, and stack cashback where possible. The sale window closes 13 July 2026, so have your bookings ready before then.
