CompRadar methodology

How CompRadar Compares UK Competitions

CompRadar uses a consistent value model to compare paid UK competition listings. It is an estimate based on provider data, not a prediction of a winner and not a guarantee that a listing or provider is legitimate.

Compare Competitions

In brief

What the score means

The score estimates the value available for each paid entry using prize value, estimated current entries, ticket price, sales progress and a small source-level adjustment. Higher is better on this model. It does not calculate a verified probability of winning.

Methodology version 1.0 · Last updated 24 August 2026

01

Prize value per estimated entry

The base value is the estimated prize value divided by the entry count used for scoring, then divided by the ticket price.

Base value = (prize value ÷ scoring entries) ÷ ticket price.

02

Sales progress

The model adds up to 18% when a listing is early in its sales cycle. Above 80% sold, a separate penalty rises gradually to 8% at sell-out.

03

Ticket price

Price already affects the base value. In addition, tickets above £5 receive a gradual penalty of (price − £5) ÷ 50, capped at 25%.

04

Source-level adjustment

The code uses 4 as neutral. A source value changes the multiplier by 6% for each point above or below 4. Dream Car Giveaways, 7 Days Performance, Rev Comps and High Peak Comps are currently configured at 4.5, producing a 3% uplift; other sources default to 4.

This is a configured reliability signal, not an audit, endorsement or legal assessment of a provider.

Calculation

From raw value to 0–100

The base value is multiplied by the sales, price and source adjustments. The result is capped to an expected raw range of 0.10 to 120, converted on a logarithmic scale, and rounded to one decimal place.

85–100Excellent Value
70–84.9Good Value
50–69.9Average
Below 50Poor Value

Odds and entries

Advertised odds versus estimated current odds

Maximum entries is the provider’s stated ticket ceiling. If there is one winning entry and every ticket sells, this gives advertised odds of 1 in the maximum entries. CompRadar obtains that ceiling from public listing pages or provider APIs; it does not receive private sales records.

Estimated tickets sold is different. When a provider supplies a sold count, CompRadar uses it. Otherwise it calculates total tickets minus tickets remaining, or applies the displayed sold percentage to the maximum. The “estimated current odds” shown are 1 in that current sold-entry estimate. They assume one relevant winning entry and one ticket per entry.

When no sold information is available, the listing falls back to the maximum entries. The scoring calculation also applies an early-stage floor so a newly launched listing does not appear unrealistically valuable: 12% of maximum entries below 2% sold, 8% below 8% sold, and 5% thereafter. The larger of this floor and estimated current entries is used for value scoring.

Price and prize

How monetary values are obtained

The ticket price comes from the public provider listing. Prize value uses an explicit prize value or cash alternative when available; otherwise CompRadar extracts the largest £ amount stated in the title.

For vehicle competitions only, if no usable figure is present—or the title amount is below 40% of a fallback estimate—the code estimates the vehicle at 52% of ticket price multiplied by maximum entries. This is a broad proxy, not an independent vehicle valuation. A larger prize raises the score; a higher ticket price lowers it.

Missing data

When a competition is not ranked

Paid listings need a valid ticket price, maximum entry count and usable prize estimate. If any is missing, invalid or zero, the listing is marked “Not ranked”. Free competitions are also not assigned a paid-entry value score. Missing sold data falls back to maximum entries as described above.

Data freshness

How often listings refresh

CompRadar’s scheduled collectors are configured to run every five minutes. While a comparison page is open, supported public feeds are checked as often as once per minute. A source outage, changed page structure, caching or delayed provider update can make a listing older than that schedule; the page’s “last checked” field shows the newest source timestamp available.

Independence and limitations

What the score cannot tell you

Affiliate or other commercial relationships do not change the formula, weights, inclusion rules or ordering. CompRadar does not sell entries, operate draws, choose winners or guarantee providers or listings.

The model assumes public ticket counts are accurate, a sold ticket represents one entry, the relevant prize has one winning entry, and extracted or estimated prize values are reasonable. Multiple prizes, bundles, discounts, free postal entries, instant wins, skill questions, taxes, delivery costs and provider terms may not be reflected. Current sales can change between checks.

Always confirm the price, availability, closing date, entry route and full terms on the provider’s website. Read our responsible participation guidance, learn about the project, or report inaccurate data.
