✅ Before you buy anything
- Check the price history (tips below). Near its lowest = real deal. Near its average = normal price.
- Do the free fixes first: draught-proof doors, close curtains at dusk, set your heating timer, and boil only the water you need.
- Need it now? Buy it at a fair price. Don't let damp or a broken heater wait for a sale.

🔋 Power banks
Small, cheap and often discounted. A good buy if you don't have one charged and ready for a power cut.
Anker Zolo 20,000mAh power bank (30W, built-in USB-C)
Your phone is your torch, radio and news feed. A 20,000mAh bank charges a typical phone about four times.
- Lowest tracked on Amazon: £24.98 (May 2025)
- Lowest from a marketplace seller: £23.49 (14 Nov 2025)
- Amazon average: £29.43
Which?'s Black Friday power bank pick is the INIU BI-B6 10,000mAh: six-month average £17.34, cheapest £12.72.
🛋️ Heated throws and electric blankets
Heating the person, not the room, is one of the cheapest ways to stay warm. Throws and blankets are popular gifts, so they're heavily promoted in November.
Electric heated throw, 160 x 130cm
Heat the person, not the room. A throw on the sofa can let you turn the thermostat down a notch.
- Lowest tracked: £23.79 (27 Feb 2026, after winter)
- Average: £29.09
- Last seen: £29.99 (23 Oct 2026)
Silentnight Comfort Control electric blanket, double
Heating the bed rather than the house is one of the cheapest ways to sleep warm.
- Amazon average: £37.12
- Highest tracked on Amazon: £119.28 (4 Nov 2025, three weeks before last Black Friday)
- Last seen: £40.00 (Oct 2026)
Which?'s picks: Dreamland Nap Time heated throw (six-month average £109, cheapest £80) and Russell Hobbs RHEDB8002 underblanket (average £72, cheapest £43).
💧 Dehumidifiers
Which? warns that Black Friday falls in peak dehumidifier season, so retailers don't need to cut prices and deals are scarce. If you've got mould or wet windows now, don't wait for a sale.
Pro Breeze 12L/day compressor dehumidifier
A compressor dehumidifier pulls litres of water out of the air. It's the step up when windows run wet every morning.
- Lowest tracked: £97.49 (Nov 2019)
- Average: £126.78
- Last seen: £129.99 (7 Nov 2026)
Meaco Arete One 10L compressor dehumidifier / air purifier
A 151W compressor model: about 4p an hour at the Oct–Dec 2026 price cap (26.32p/kWh). The humidistat switches it off once the room reaches your set level, so real costs are usually lower.
- Buy direct from Meaco (UK dehumidifier specialist)
- About 4p an hour to run (151W) at the Oct–Dec 2026 price cap
Meaco Arete One 20L compressor dehumidifier / air purifier
More extraction for whole floors, bad condensation or drying washing indoors. 216W: about 5.7p an hour at the current price cap.
- For whole floors and drying washing
- About 5.7p an hour (216W)
🌡️ Smart thermostats
tado's UK shop already had a sale on 8 November: the Smart Radiator Thermostat X was £59.99 (from £79.99). Treat that as the price to beat.
tado° Smart Thermostat Starter Kit V3+
Schedules and app control help you stop heating an empty house.
- Lowest tracked on Amazon: £79.06 (June 2025, in summer)
- Amazon average: £116.13
- Last seen from a marketplace seller: £109.99 (5 Nov 2026)
A smart thermostat only saves money if you use the schedule and room-by-room control. The free fix is to set your timer and turn the thermostat down 1°C.
📊 Energy monitors
If you have a smart meter, the in-home display from your supplier already shows what you're using, for free. A smart plug shows what one appliance uses.
Tapo P110 smart plug with energy monitoring, 2-pack
Shows exactly what each plugged-in appliance uses, so you know what's worth switching off and what isn't.
- Lowest tracked on Amazon: £14.18 (21 Jan 2026)
- Amazon average: £16.72
- Last seen: £15.49 (7 Nov 2026)
🍟 Air fryers
One of the most-promoted Black Friday categories. Big percentage-off claims are common, so check the history.
Ninja Air Fryer MAX PRO 6.2L single drawer (AF180UKCP)
Ninja's large single-drawer model. Air fryers use less energy than heating a whole oven for small meals.
- Lowest tracked on Amazon: £89.98 (20 Nov 2025, last Black Friday week)
- Highest tracked: £226.99 (2 Oct 2025)
- Amazon average: £150.33
Which?'s air fryer pick is the smaller Ninja MAX 6.2L AF170UK: six-month average £123, cheapest £100.
🫖 Kettles
Kettles are cheap to buy, so a Black Friday saving is usually only a few pounds.
Bosch MyMoment Delight cordless kettle 1.7L (TWK1M123GB)
Which?'s Black Friday kettle pick. Boil only the water you need: the kettle costs more to run than to buy.
- Lowest tracked on Amazon: £24.00 (11 Oct 2025)
- Amazon average: £31.88
- Last seen: £24.99 (8 Oct 2026)
Which? estimates this kettle's annual running cost at £33.67, more than it costs to buy.
❌ Skip these: fake deals
These are the tricks that make a normal price look like a bargain.
Savings against an RRP
An RRP is the manufacturer's suggested price. The shop never has to have charged it. Which? found Amazon advertised a Samsung Series 5+ heat pump tumble dryer at £629.99 against an RRP of £789.99, a 'saving' of £160, but Amazon hadn't sold it at £789.99 at any point in the previous 12 months. Its highest price was £719.
A 'was' price from a spike
Prices can jump before the sales. Amazon's highest-ever recorded price for the Silentnight double electric blanket, £119.28, was on 4 November 2025. Its average is about £37. Any 'was £119' would be a meaningless anchor.
'Was' prices from months ago
Which? found some 'was' prices dated from as far back as 11 months earlier, and in a study of TVs 56% had at least one cheaper price in between.
Countdown clocks and '30 people are viewing this'
Pressure selling is designed to rush you. Which? found that on Black Friday itself, none of the deals it tracked were at their cheapest price of the year.
Dehumidifier 'deals' in peak season
Black Friday is in the middle of damp season. Which? says retailers don't need to cut prices to shift dehumidifiers, so most 'deals' are just the normal price.
Unknown-brand bundles
A big percentage off a no-name bundle is impossible to check. If you can't find the same item for the same price elsewhere, you can't know what it's worth.
🔍 How to spot a fake deal in 60 seconds
- Check the price history. Paste the product into a tracker such as camelcamelcamel (Amazon only), PriceSpy or PriceRunner. If it's been this price before, it's not special.
- Compare at least three shops. If four shops sell it at the same price and only one calls it an offer, it isn't one.
- Ignore RRP. Only a shop's own recent price means anything.
- Know the rule. The CMA says a 'was' price should be what the same website actually charged immediately before the sale, for a decent period (it suggests 30 days or more is more likely to be fair).
- Check the final price. Include delivery and any extras before you compare.
- Don't rush. Which? found 35% of Black Friday deals were cheaper again after the sales. Online, you normally have 14 days to change your mind after delivery (Consumer Contracts Regulations).

Questions people ask
When is Black Friday 2026?
Friday 27 November 2026. Cyber Monday is Monday 30 November. Amazon's Black Friday Week runs from 19 to 30 November 2026.
Are Black Friday deals real?
Some are, most aren't special. In Which?'s study of 175 deals from Black Friday 2024, every product was the same price or cheaper at some point in the six months either side, and none was at its cheapest on the day itself.
Should I wait until after Black Friday?
If you don't need it now, waiting is fine: Which? found 35% of deals were cheaper after the sales period. If you need it now (mould, a broken kettle, a power cut coming), buy it at a fair price and don't chase a deal.
How do I know what a fair price is?
Look up its price history and the average price. If today's price is near the lowest it's ever been, that's a real deal. If it's near the average, it's just the normal price with a sale sticker.
Why don't you show today's prices?
Prices change by the hour during the sales, so we show the price history and a 'real deal' target instead. Always check the current price on the retailer's site.
