Black Friday Is Twelve Weeks Away. The Decisions Are Due Now

Black Friday falls on 27 November 2026, with Cyber Monday on 30 November. Early-bird promotions now begin around 30 October, so the practical deadline is roughly eight weeks away rather than twelve. The average UK shopper plans to spend about £445 across the period, slightly up on last year, and more than 12.5 million transactions are forecast on the Friday alone.

For a small business, almost every decision that determines how that period goes is made in September. Stock lead times, ad budgets, list building and the discount decision itself all have to be settled before the season starts.

Should you discount at all?

This is the decision people postpone and then make by default in the third week of November, which is the worst possible time to make it.

Two facts should shape it. First, Black Friday 2025 did not repeat the boost seen in 2024, so the assumption that participation guarantees uplift is out of date. Second, shoppers are planning against strain: average credit card balances are at a record £1,975 and arrears are rising across every stage of delinquency.

That combination produces a specific consumer behaviour. Black Friday has shifted from impulse purchasing to planned purchasing, with people using the period to buy Christmas gifts they had already decided to buy. Discounts increasingly move the timing of a sale rather than creating one.

If your situation is	The likely right move
Stock you need to clear before year end	Discount, and go early rather than deep
Products people research and compare	Compete on availability and delivery certainty, not price
Services or B2B	Usually skip it entirely, and say so plainly
Strong repeat customer base	Early access for existing customers, no public discount

The last row is the one most often missed. Giving your existing list first refusal costs nothing, converts far better than a public discount, and does not train the wider market to wait for your sales.

What to build in September

In rough order of return for a small business:

1. A list to sell to. The single highest-return action available between now and October is growing and warming the list you already have. A discount announced to nobody is just a lower price.
2. Back-in-stock and waitlist capture. If something sells out during peak, the enquiry is worth more than the sale you missed. Capturing it automatically costs nothing and pays off in December.
3. Abandoned basket recovery. Well-trodden ground, and still absent from a surprising number of small e-commerce sites. Set it up now so it is tested before volume arrives.
4. Delivery and cut-off dates published early. In a period defined by planned rather than impulse buying, certainty converts. Ambiguity about whether something arrives before Christmas loses the sale to a competitor who was specific.
5. A plan for enquiry volume. Support and enquiry load rises with sales, and the businesses that struggle in December are usually the ones that only planned for the orders.

What not to do

Do not build anything new and complicated in November. Whatever you deploy in the fortnight before peak will fail during peak, because it will not have been tested at volume by anybody. If it is not live and working by the end of October, it should wait until January.

Do not discount to match a competitor whose cost base you do not know. Their margin structure is not yours, and a discount war during a period of weak consumer spending is a good way to buy revenue at a loss.

If Black Friday is not your market

Say so, internally and externally. A large share of UK SMEs, particularly in services, trades and B2B, have no business running a Black Friday promotion, and the effort spent producing one is better spent on Q1 pipeline while competitors are distracted.

The general point holds regardless of sector: whatever your busiest period is, the decisions that determine how it goes are made about three months out. For retail and e-commerce that clock started this week.
