UK room cooling-load field tool

What size air con does this room need?

A transparent planning range based on the heat entering one room—not a rule of thumb based on floor area alone.

Not a professional system design. Your estimate is saved privately as a draft claim for method review.

WAITING FOR ROOM DATA

Your range will appear here.

Not just a number: you’ll get a load breakdown, running-cost estimate, source ledger and calculation ID.

WHAT THE TOOL COMBINES

One answer. Four evidence layers.

The estimate combines room heat gains, market design conditions, your electricity price and a screening estimate of daytime solar overlap. The result names its version and sources so it can be reproduced.
