Hearthsum, With Receipts

Editorial interest 81/100 Selection signal · not a rating of the site

A UK solar-cost reference covering grants, free-solar eligibility, export rates and payback calculations.

Landing page captured for the 2026-09-09 issue.

Field notes

The site organizes its reference material into five practical paths: installation cost, grants, free-solar claims, Smart Export Guarantee rates and payback. Its stated method is to attach a source link and last-checked date to each figure, while keeping the Energy Saving Trust’s published inputs separate from Hearthsum’s own calculation. The homepage also flags two time-sensitive thresholds: ECO4 installation by 31 December 2026 and the end of 0% VAT on solar and batteries on 31 March 2027.
