Building credit history at 18

LESSON Lesson structure (50 minutes)

Opening
HOOK
Ask: "Who knows what a credit score is?" Take responses. Then: "A 28-year-old applying for a £200,000 mortgage with a great credit score might get a rate of 4.2%. The same person with a poor score might get 5.5% — or be refused. Over 25 years, that's £40,000 of extra interest. What you do at 18 affects what you pay at 28."
Direct teach
TEACH
Explain the UK system: three main CRAs hold separate records (Experian, Equifax, TransUnion). Each has its own score range. Lenders may use one or several when assessing you. Your credit FILE shows: registered electoral roll address, financial accounts, missed payments, hard searches by lenders, court judgments (CCJs), bankruptcies. Length of history matters as much as score.
Pupils apply
GUIDED
Sorting activity: distribute cards with actions. Pupils sort into "builds" / "damages" / "neutral":
  • Registering on the electoral roll
  • Missing a credit card payment
  • Cancelling old credit cards
  • Taking out a phone contract and paying on time
  • Applying for many credit cards in a month
  • Paying student loan via PAYE
Discuss answers as a class.
Stretch / depth
CHALLENGE
Show two 28-year-old applicants for the same £180,000 mortgage. Both earn £40,000. Applicant A: registered to vote at every address, never missed a payment, has a 3-year-old credit card. Applicant B: not on electoral roll, missed two phone bills 2 years ago, no credit history. Discuss: who gets the better rate? Why? What COULD Applicant B have done differently at 18-22?
Close
PLENARY
Each pupil writes one action they'll take when they turn 18 to start building credit responsibly. Share three. Land on: register to vote at uni, get a basic credit card and pay it off in full each month, don't miss any payments.

DIFFERENTIATION Adapting for all learners

Support (working below ARE)

Focus on three actions: register to vote, pay everything on time, don't apply for credit you don't need. Don't require understanding of the three-CRA structure.

Stretch (working above ARE)

Pupils research the difference between "soft" and "hard" credit searches. Calculate the impact on a credit application of 5 hard searches in 30 days.

SEND SEND adaptations

For pupils with autism: provide a clear cause-and-effect diagram showing how each action affects the score. For dyscalculia: avoid score numbers; use words ("good", "weak") instead.

EAL EAL support

Vocabulary: "credit report", "Credit Reference Agency", "electoral roll", "hard search", "soft search", "missed payment", "CCJ". Sentence frames: "I should ___ because it builds my credit score."

ASSESSMENT Assessment criteria

Pupils can: (1) name the three UK CRAs; (2) list three actions that build credit; (3) list three actions that damage credit; (4) explain how an 18-year-old's credit history affects a 28-year-old's mortgage rate.

HOME Homework pack

Three activities consolidating credit history mechanics. ~30 minutes.

CRA comparison

What pupils do: Research the three UK CRAs. For each, find: typical score range, how they let consumers check their own score for free, one major UK lender that uses primarily their data.

Expected output: Table with 3 rows × 3 columns.

Marking guidance: 9 marks — 3 per CRA (1 per cell).

5-year plan

What pupils do: Write a 5-year credit-building plan for a hypothetical 18-year-old starting university with no credit history. Include specific actions per year.

Expected output: 5-year plan with year-by-year actions.

Marking guidance: 8 marks — 1.6 per year for specific, accurate actions.

Mortgage impact

What pupils do: Explain in 250 words how a missed credit card payment at age 19 could affect mortgage affordability at age 28.

Expected output: 250-word structured response.

Marking guidance: 6 marks — 2 for mechanism, 2 for time lag, 2 for cost quantification.

HOME Homework pack

Four activities to consolidate UK income tax mechanics. ~30 minutes.

Band calculation

What pupils do: For each gross salary, calculate the UK income tax (England/Wales/NI 2026/27 rates): (a) £15,000, (b) £30,000, (c) £55,000, (d) £85,000. Show the band split for each.

Expected output: 4 calculations with band-by-band working.

Marking guidance: 2 marks per accurate total (8 marks). Bonus 4 marks for correct band splits.

Personal Allowance research

What pupils do: What is the Personal Allowance? Why does it exist? Who loses it (the taper rule)?

Expected output: A 3-question short-answer response.

Marking guidance: 2 marks per accurate answer. 6 marks total.

Public spending

What pupils do: Find 5 different things UK income tax pays for. Order them by approximate share of government spending (biggest first).

Expected output: A ranked list of 5 spending categories.

Marking guidance: 1 mark per category, 1 mark per correct relative ranking. 8 marks total (e.g. NHS, pensions, education, defence, welfare).

Extension (optional)

What pupils do: Compare England, Scotland, and Wales income tax for someone earning £50,000. Which nation pays the most? Why?

Expected output: A 3-nation comparison table plus 2-sentence explanation.

Marking guidance: Up to 6 marks for accurate research and conclusion (Scotland pays more above ~£28k).

Family discussion prompt (safeguarding-aware)

Ask a working adult: "Name three things you think our tax money pays for." Compare their answers to what you learned in class.

SAFEGUARDING Classroom safeguarding

Note for teachers: Do not ask pupils about their own family's tax band, salary, or income. Frame all examples through fictional salaries. Be aware some pupils may be unsure of family financial circumstances — focus on the public-spending side of the lesson, not personal income.
