As of 13 August 2026, AI can only partly check whether your loft needs more insulation.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a free chatbot and paste the prompt, replacing each bracketed slot with your own information without guessing measurements.
   2. From the loft entrance, take clear photographs of the insulation across the whole accessible area, including edges, eaves, hatch, pipework, tanks, cables and any damp or staining.
   3. Measure the insulation depth in several representative places without compressing it, and record where there are gaps, squashed sections or areas you cannot reach.
   4. Add details of the roof age if known, recent repairs, condensation, draughts, stored items and anything that makes entering the loft unsafe, then send the photographs and prompt together.
   5. Ask the chatbot to return a table with visible evidence, uncertainty, safe checks and reasons to stop and seek an inspection, then compare every measurement in its answer with your notes and photographs.
   6. If there is suspected damp, damaged wiring, unsafe access, or a condition the chatbot cannot assess, do not add insulation there and contact a qualified UK insulation installer or another appropriate building professional.
   7. Use the chatbot's installer-question list when requesting an assessment, and ask the installer to explain ventilation, moisture, access and the treatment of existing insulation before work begins.

   Prompt

   Help me make a preliminary check of whether my UK loft may need more insulation. Do not present this as a survey, diagnosis or guarantee, and do not invent measurements or building details. Use only the information and photographs I provide. Separate what is visible from what is uncertain. Assess the apparent insulation coverage, measured depth, gaps, compressed areas, damp or staining, draughts, stored items, ventilation, pipework, tanks, cables and access constraints. Tell me which observations I can safely check myself, which could make adding insulation unsuitable, and what evidence would change your view. Give me a short list of questions to ask a qualified UK insulation installer. If the photographs or measurements are insufficient, say exactly what cannot be checked rather than guessing. Information supplied: [property age or approximate age] [loft photographs] [measured insulation depth in each area] [visible signs of damp, staining or mould] [ventilation or draught details] [pipework, tanks, cables and stored items] [recent roof or insulation work] [anything that seems unsafe].
