Every position on this chart is the output of the Goodfirms ranking algorithm - a weighted composite of signals across two axes. The algorithm is recomputed regularly and is fully documented.

How the heatmap is built

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.

Top company names per cell are surfaced by Value Score - a weighted blend of affordability (50%) + rating (35%) + review volume (15%).

The "Best" ribbon marks the cell in each row where firm density, ratings, and affordability line up best - the densest, highest-quality combination.

Read the full methodology

Value Score · per firm

ValueScore = 0.50 × Affordability

// Affordability = (1 - rate/$200) × 100

// Rating = (rating - 3) / 2 × 100

// Volume = log10(reviews+1)/log10(200) × 100
