The Samsung Galaxy S25 Ultra launched in early February 2025 as Samsung’s 2025 flagship.

Buying Guide: How to Get the Best Deal in the UK
1. SIM-free vs contract
- SIM-free (recommended for most people long-term): Buy unlocked and pair with a cheap SIM-only plan. Over 24 months this is often cheaper than a handset contract once you factor in mid-contract price rises on many networks.
- Contract/pay-monthly: Useful if you want low or zero upfront cost and prefer everything in one bill. Look carefully at total cost of ownership (upfront + monthly payments + any annual price rises). Good deals appear on comparison sites with totals sometimes well under the original RRP.
2. Trade-in
Samsung and major retailers (Currys, Amazon, networks) still accept trade-ins. Values depend on model and condition. Older flagships (S23 Ultra, S24 Ultra, etc.) can knock several hundred pounds off. Samsung has run promotions with guaranteed minimums (e.g., £100 off any working smartphone) plus higher values for recent devices. Check current trade-in estimators on Samsung.com or retailer sites.
3. Where to buy
- Samsung.com — Best for exclusive colours, official trade-in, Care+, and any ongoing promotions or cashback.
- Major retailers — Currys, Amazon, Argos, John Lewis.
- Comparison sites — Uswitch, MoneySavingExpert, PriceRunner, Smartphone Checker, etc., for live contract and SIM-free deals.
- Refurbished specialists — Back Market, certified refurbished from networks or Amazon Warehouse for bigger savings (check battery health and warranty).
4. Storage advice
- 256GB is fine for most users who use cloud storage or don’t shoot huge amounts of 8K/4K video.
- 512GB is the sweet spot for power users, photographers, and those who keep lots of apps/media offline.
- 1TB only if you need maximum local storage or plan to keep the phone for many years.
5. Extra tips
- Watch for seasonal sales (Black Friday, Prime Day equivalents, Samsung promotions).
- Consider Samsung Care+ for extended protection.
- Verify the phone is UK/EU spec (correct bands and warranty).
- Factor in accessories: a good case and screen protector are worthwhile given the large, premium display.
Frequently Asked Questions
What is the current cheapest price for a new Galaxy S25 Ultra in the UK?
New 256GB units are commonly available in the mid-to-high £700s (sometimes lower). Check live comparison sites as prices move frequently.
Is the S25 Ultra still worth buying now that the S26 Ultra is out?
Yes for many people. It offers excellent performance, a class-leading camera system, S Pen, and strong software support at a much lower price than the newest Ultra. The S26 Ultra brings incremental improvements, but the S25 Ultra remains highly capable.
Does it support 5G and dual SIM?
Yes — full 5G support and flexible dual SIM / eSIM configurations (exact limits depend on region/firmware).
How is the battery life?
The 5,000 mAh battery typically delivers solid all-day use for mixed workloads. 45W charging is competent but not the absolute fastest on the market.
Is the S Pen included?
Yes — it is built into the phone, as with previous Ultra models.
What about software support?
Samsung committed to 7 years of OS upgrades and security updates from launch, putting it among the longest-supported Android phones.
Can I get a good deal with trade-in?
Often yes. Values have declined since launch but remain meaningful, especially for recent Samsung or Apple flagships. Combine with retailer promotions for the best result.
Where should I check prices right now?
Samsung.com for official pricing and promotions, plus Uswitch, MoneySavingExpert’s cheap mobile finder, PriceRunner, and major retailers for the lowest live offers.
Prices and deals change regularly. Always verify the latest figures, stock, and terms directly with retailers before purchasing. The Galaxy S25 Ultra continues to offer excellent flagship value in the UK market as discounted stock clears.
