 Best mobile phone deal

Google Pixel 9a

Average price in the past six months: £399
Cheapest price in the past six months: £286*

• 6.3-inch display with 2,424 x 1,080 resolution
• Google Tensor G4 processor with 8GB of Ram
• Two rear camera lenses, including a 13Mp ultra-wide camera

We like: Strong rear cameras

We don’t like: Front-camera videos could be better

This mid-range Android phone comes close to the capabilities of the higher-end Pixel 9 series models. It’s even powered by the same Google Tensor G4 processor as the more expensive Pixel 9 and Pixel 9 Pro phones.

It has a pOLED (plastic OLED) display, a very high peak brightness level and a 120Hz refresh rate. Plus, it comes with the promise of seven years of security updates.

The camera system has also been improved with a 48Mp main lens and a 13MP ultrawide lens. On the front, there’s a 13Mp selfie camera. It’s also the first A-series phone to have the macro focus feature – aiming to provide extra detail when shooting a subject up close. 

Read our Google Pixel 9a review to see if these features work as well as you hope they will.

 Best tablet deal

11-inch Apple iPad (2025)

Current price at Apple UK: £429 (Note: the launch price of the iPad was £329 - it's now £429 after Apple hiked its prices in June this year.) 

Average price in the past six months: £423
Cheapest price after the June price rise: £399* 

• 10.9-inch screen
• 6GB Ram
• 128GB of storage

We like: Cheapest iPad since 2022

We didn't like: No Apple Intelligence

The 2025 iPad is sure to tempt Apple fans, launching at almost half the price of an iPad Air and £170 less than the iPad mini. But recent Apple price rises are filtering through to retailers now, and it's hard to find deals as keen as we've seen in the past. But if you want an iPad now, this is the most affordable option.

It has a 10.9-inch screen with 2,360 x 1,640-pixel resolution. It runs on the A16 Bionic chip, which is the same processor found in the iPhone 15.

It has a sleek finish and comes in four colours: blue, pink, silver or yellow. It doesn’t come with Apple Intelligence, though, which is Apple’s latest software suite powered by AI.

Get all the information you need about this iPad with our Apple 11-inch iPad (2025) review.

Best TV deal

LG OLED48B56LA 

Average price in the past six months: £759
Cheapest price in the past six months: £521*

• 48-inch 4K TV
• OLED display
• Supports HDR10, HLG and Dolby Vision formats

We like: Good remote

We don't like:  Obtuse data collection terms

LG was the first brand to release OLED TVs, and its screens are synonymous with quality. The 48-inch OLED48B56LA is one of the cheapest it produces (costing even less than some 42-inch models), and it’s not exactly light on features or advanced technology.

Every gaming option you could wish for is available here, including FreeSync, G-Sync and variable refresh rates. And you can use it as a PVR.

LG TVs are also some of the simplest to use; the magic remote is clearly labelled, with a well-thought-out layout. Spending less on this B-range model could be a great way to get Best Buy OLED quality for less, but are there compromised features that you'll end up regretting?

Check out the full LG OLED48B56LA review to see how this one scored in our tests.

 Best vacuum cleaner deal

Dyson V8 Cyclone Cordless Vacuum

Average price in the past six months: £362
Cheapest price in the past six months: £219*

• Bagless and cordless stick vacuum cleaner
• 0.6 litre dust capacity
• Weighs 2.6kg

We like: Simple to manoeuvre

We don't like: Could be easier to use at height and on uneven surfaces

This cordless, bagless vacuum cleaner has 'triggerless' operation, so you don't need to keep the power button pressed while using it. You can switch between three power modes (eco, medium and max), and it can be used as a handheld cleaner on stairs, furniture or car interiors

The V8 Cyclone comes with a mini turbo brush, crevice tool and a wall dock. The floorhead has an anti-tangle brush bar, designed for hard floors and carpets. You can also buy the V8 Cyclone with just a crevice tool, but they're currently both going for the same price, so you might as well go for this deal with the extra tools.

Is the battery life of this vacuum as good as Dyson claims? Find out in our full Dyson V8 Cyclone review.

Best washing machine deal 

LG F4Y510WBLN1

Average price in the past six months: £447
Cheapest price in the past six months: £369*

• Freestanding
• 10kg cottons capacity
• White

We like: Excellent spin

We don't like: It has some ease-of-use niggles

The LG F4Y510WBLN1 is a freestanding white washing machine with a larger 10kg capacity and 1,400rpm maximum spin speed.

There are 12 programs to choose from, plus a steam function that can be used to reduce allergens. Additionally, it uses sensors to weigh the load and adjust washing times accordingly, potentially saving water and energy. You can also add items to the wash while the program is running.

You can delay the wash end time for up to 19 hours, and the digital display shows how much wash time is left. You can also lock the control panel to stop your settings from being accidentally changed by knocks or inquisitive little fingers.

Will you have to make compromises with such a good-value machine? Our LG F4Y510WBLN1 review reveals all.

Best built-in oven deal

Indesit IO 232H B UK

Average price in the past six months: £211
Cheapest price in the past six months: £149*

• Single electric
• Black
• Not self-cleaning

We like: The interior space is flexible

We don't like: The handle is not especially comfortable 

This Indesit single built-in electric oven with a grill could be a good choice if your key concern is getting a really low price.

It comes with two wire shelves and a baking tray, and has a minute minder and an ‘eco cleaning’ function that uses steam to gently loosen food grime.

Unlike many other electric ovens, it doesn’t have a fan, but you'll need to read our full review to see if this compromises its cooking capabilities. Another unusual feature of this oven is that it comes with a plug, so you'll avoid the expense of employing an electrician to hardwire it.

To find out if this oven cooks well, even without a fan function, read our full Indesit IO 232H B UK oven review.

Best dishwasher deal

Bosch SMV4HTX00G 

Average price in the past six months: £526
Cheapest price in the past six months: £459*

• Full-sized
• Fully integrated 
• 13 place settings 

We like: It's efficient to run 

We don't like: It can be a little noisy 

This full-sized, fully integrated dishwasher has seven programs, including main, eco and fast washes, along with intensive, delicate and machine care cycles.

You can select an extra-dry mode to lengthen the drying cycle, choose a half-load wash and activate speedperfect+ to reduce the run time of selected programs. There’s also an additional silence mode, which Bosch claims reduces cycle noise. All cycles can be delayed by up to 24 hours. 

It has wi-fi connectivity, so you can start the dishwasher remotely using the Home Connect app on your smartphone. You can also download additional programs, and monitor the machine’s energy use. It has a five-year warranty.

But is it good enough to be a Best Buy? Read our full Bosch SMV4HTX00G review to find out.

 Best fridge freezer deal

Fridgemaster MC55251DE

Average price in the past six months: £339
Cheapest price in the past six months: £269*

• Freestanding
• Frost-free freezer
• White

We like: It's quiet

We don’t like: It has some ease-of-use niggles

The Fridgemaster MC55251DE is a freestanding fridge freezer with a white finish. The handy cool water dispenser on the front may appeal, plus the doors are reversible, so you can change the direction they open to suit your kitchen. 

It’s fairly basic, so there’s no fast-freeze or super-cool modes, plus it lacks the open-door alarms that you might find on rival models.

This is the white version, but there are also stainless steel (MC55251DES) and black (MC55251DEB) models available that are identical in all other respects.

But will it store your food properly and keep your salads crispy?  Read our full Fridgemaster MC55251DE review to find out.

Best laptop deal

HP OmniBook 5 14" Next Gen AI Laptop

Average price in the past six months: £861
Cheapest price in the past six months: £650*

• Snapdragon X-X126100 processor
• 16GB Ram
• 512GB SSD storage

We like: Slim and light

We don't like: No HDMI or SD card slot

This Omnibook is one of HP's higher-end laptops. It has a 14-inch 2K OLED display and, at 1.3kg and only 17mm high with the lid closed, is very portable for a model of this size. 

It's powered by a Qualcomm Snapdragon X AI-compatible processor, 16GB Ram and 512GB solid-state drive (SSD). That’s impressive for a home computer.

It’s worth noting that the Snapdragon CPU is ARM-based, similar to the chips found in phones and Macs. Laptops with ARM processors are gaining popularity due to their impressive performance and power efficiency. But ARM devices can occasionally run into compatibility issues with software and hardware designed for traditional Windows computers.

 Best mattress deal

Sleepsoul Heaven 

Average price in the past six months: £258
Cheapest price in the past six months: £193*

• Double
• Pocket sprung

We like: Easy to move around on

We don't like: Stability could be better

The SleepSoul Heaven features a large pocket sprung core, topped with layers of foam, that has plenty going on underneath the cover. It’s a boxed mattress, which arrives rolled up, making it much easier to get to the room of your choice. 

Internally, you’ll find a large 21cm pocket spring core, which is the reason we classify this as a pocket sprung mattress rather than a hybrid.

It’s available with a 60-night comfort trial so you can try it out to see if you like it, plus it also comes with a 10-year guarantee. 

Our Sleepsoul Heaven mattress review reveals whether this mattress will provide the perfect night's sleep.

September sale shopping tips

Check the Which? website

Which? senior consumer editor, Faith Strickland says:

'As well as telling you which products are best and which are lacking, we’ve also put together a list of the best and worst shops. 

'We’ve quizzed thousands of Which? members on their experiences of shopping in some of the country’s best-known stores and websites, as well as with lesser-known brands. 

'After crunching the numbers, we can reveal which retailers score highly for product quality, range and value for money. To see the retailers that impressed in our latest shopping survey, head to our extensive guides on the best and worst shops.'

Watch out for sneaky tricks

Some retailers use underhand tactics to pressure you into making a purchase. 

These include anchor pricing (when products are on sale more often than they aren’t), pressure selling (‘30 people are viewing this right now!’) and dubious claims about the ‘before’ price of a product. 

If you’re unsure how good a deal is, use a tool such as PriceRunner to compare prices across retailers. 

Research customer reviews

It’s always a good idea to read reviews before you buy a product, but not all are trustworthy. 

Some sellers incentivise people to post fake positive reviews to drown out genuine negative ones. If you’re in any doubt, check our expert guide on how to spot a fake review. 

Returning goods

Whether you bought a product in-store or online, you still have rights under the Consumer Contract Regulations. 

The regulations give you a 14-day window to return a non-faulty product, starting from the day you receive your goods. Many retailers will give you longer than this, but it's always best to check before you buy. 

See our online returns guide for information on the additional rights you have when shopping online.
