Methodology

Every number. Every formula. Every source.

Last verified 5 Jun 2026 · Source v304 calibration document + monthly review cadence

This is how SortedUK calculates every result it shows you. Every benefit rate, Pension Credit calculation, Universal Credit estimate, Stamp Duty figure, Mortgage Ready Score, Better Off calculation and risk badge is explained in full, with its formula, official source, last-verified date and confidence band. We show how each figure is calculated, where the data comes from, and what assumptions are used. If you want to verify SortedUK's benefits, financial support and money guidance, this is the page.

1. Letter decoding & risk badges

Last reviewed 1 Jun 2026

SortedUK's decode-v2 tool reads UK letters from HMRC, DWP, local councils, courts, DVLA, NHS and other official organisations. It identifies the sender, explains what the letter means in plain English, highlights important deadlines, shows what may happen if you take no action, recommends your next step and assigns a colour-coded risk badge. This includes benefit letters, Universal Credit letters, Pension Credit letters, council tax notices, court claims and other official UK correspondence.

How we identify the sender

How we set the risk badge

Rule: when in doubt between 🟡 and 🔴, choose 🔴. We would rather over-warn than under-warn on a letter where missing the deadline is irreversible.

2. Deadline detection

Last reviewed 1 Jun 2026

The decoder identifies deadlines using: (a) UK date-format and ISO-date pattern matching within the letter, (b) keyword detection around phrases such as "reply by", "deadline", "no later than", and "within X days or weeks", and (c) sender-specific UK rules when no explicit deadline is stated.

This is particularly important for HMRC letters, DWP benefit letters, Universal Credit decisions, Pension Credit correspondence, council notices, parking penalties, court claims and other official UK communications where missing a deadline can affect your rights, appeal options or entitlement.

Default deadlines are based on official UK rules and guidance, not estimates:

3. Better Off Scan — your potential annual financial support

Last reviewed 1 Jun 2026

The Better Off Scan asks seven questions about your household, income, age, employment, home and circumstances, then identifies benefits, financial support, hidden money, savings opportunities and other UK schemes you may be entitled to. Results are grouped into six panels: Money You May Be Owed, Savings You Can Make, Home Opportunities, Business Opportunities, Risks and Recommended Next Steps. Each recommendation includes an estimated annual value based on official UK scheme rates, benefit rates and financial support programmes for 2025/26 and 2026/27.

How a range is calculated

Each opportunity is assigned a realistic low and high annual value using official UK data. For example, Pension Credit calculations use actual award levels, average payments and eligibility rules published by the DWP. Similar methodology is applied to Universal Credit, Council Tax Reduction, household support schemes, discounts, grants and other financial help available through UK government and local authority programmes.

Ranges are shown instead of single estimates because entitlement can vary depending on income, savings, housing costs, employment status and household circumstances.

Total Improvement Estimate

The total annual improvement figure uses the midpoint of each qualifying range rather than the maximum possible amount. This approach is designed to avoid overstating potential entitlement. The figure represents SortedUK's estimate of how much better off you could be each year if all relevant benefits, financial support and savings opportunities apply to your situation, with a full breakdown showing the contribution of each scheme.

4. Mortgage Ready Score — 0–100

Last reviewed 1 Jun 2026

The Mortgage Ready Score takes income, deposit, target price, monthly debts, employment status and FTB status, then returns a 0–100 score across 4 weighted factors. This is a self-assessment tool, not an FCA-regulated affordability decision.

Score = (Deposit_score × 0.30) + (Affordability_score × 0.40) + (Employment_score × 0.20) + (Debt_score × 0.10) where: Deposit_score = min(100, (deposit / target_price) × 1000) // 10% deposit = 100; below 5% = under 50 Affordability_score = min(100, (max_borrow / amount_needed) × 100) // max_borrow = (income × 4.5) - (debts × 12) Employment_score = {permanent: 100, self_employed_2yr+: 80, fixed_term: 70, probation: 50, contract_unverified: 40} Debt_score = max(0, 100 - (monthly_debts / income_monthly × 300)) // debts at 33% of monthly income score 0

6. Benefits Checker & eligibility screening

Last reviewed 1 Jun 2026

The Benefits Checker screens eligibility across around 20 UK benefits, financial support schemes and household support programmes using rule-based eligibility logic. Each benefit is assessed against official DWP, HMRC, NHS and local authority guidance. We reproduce the published eligibility rules as accurately as possible and do not estimate awards beyond what the available information supports. For example, Universal Credit entitlement depends on factors such as earnings, housing costs, deductions and work allowances that cannot be calculated accurately without additional verified information. Where exact calculations are not possible, SortedUK explains the eligibility criteria and directs users to the official claim process.

Examples of eligibility rules used by the checker

The checker helps users identify benefits, financial support, Council Tax Reduction, disability benefits, household support and other UK schemes they may be entitled to, with links to official guidance and application routes where available.

7. Biggest Opportunity scoring

Last reviewed 1 Jun 2026

/biggest-opportunity scores the user against 14 known UK opportunities by combining (a) eligibility match from the 8 quiz answers and (b) £/yr value of the opportunity.

Opportunity_score = Eligibility_match × Value × Recency_decay Eligibility_match = sum of matching profile signals / max possible Value = published average £/yr award (capped at £6,000 for ranking) Recency_decay = 1.0 if scheme is live, 0.0 if closed

The top-scoring opportunity is shown in the dark hero card. The next four are runners-up. Each card cites the source for the value and the eligibility test. Examples:

8. Discover For Me — priority action

Last reviewed 1 Jun 2026

The Discover For Me 10-question wizard returns a single priority action by combining three signals from the answer set:

priority = decide_priority( doc_uploaded?, // urgent letter trumps everything concerns[], // debt > eviction > scam > opportunity life_event? // baby, redundancy, bereavement get crisis routing ) if doc_uploaded == 'urgent letter': return route('/decode-v2') elif 'debt' in concerns: return route('/debt-help') elif 'eviction' in concerns: return route('/tonight') elif life_event in ['bereavement', 'redundancy']: return route('/life-events#' + life_event) else: return route('/missing-money') // default: money discovery

Four result cards (Money / Risks / Opportunities / Local) are then personalised by the answer set. Each card routes into an existing Sorted hub.

9. Outcomes aggregation & success rates

Last reviewed 1 Jun 2026

The /outcomes ledger publishes anonymised outcome data, success rates and average £ amounts from opted-in users only. This includes outcomes from benefits claims, financial support applications, Council Tax Reduction cases, complaints, appeals and other UK guidance routes available through SortedUK. The free service stores this in your browser (localStorage); for signed-in users, accounts run on our ICO-registered backend (CA Capital Limited, company no. 10848369; ICO reference C1968991), with two-way case sync being added.

Opt-in protocol

What we publish

Outcome statistics are published only when a category reaches at least 30 verified outcomes. Below this threshold, categories are marked as "Early Data" and no success rate is calculated. This helps ensure that benefits, financial support, complaint and appeal outcome statistics are based on meaningful sample sizes rather than limited data.
