01The index
This week, per category
Each cell is one standard spec. Where three or more sellers share a price type it shows their median; where fewer do, it lists the named sellers, each price with its type. Note: a price after the Boiler Upgrade Scheme grant applies in England and Wales only.
Some seller links may earn FittedPrice a commission. It never changes the order: every list is sorted by price, then by the date we read it. How we make money

How the index is read
Once a week we read the price each seller publishes on its own site for each standard spec, and store it with its type (from, fixed or typical), whether a grant has been taken off, and the date. A price older than 14 days drops out of the index and shows as not checked recently.
Prices are compared only like for like: one spec, one price type, one grant state. Lists are sorted by price, then by the date read; commission never sets the order, and we never arrange finance. Grants differ by nation, so each one says where it applies.
