Loft, cavity wall, and external wall insulation are genuinely different jobs with different survey requirements, materials, and risks. Quoting them under one generic "insulation" line hides that difference. A cavity wall job in particular needs a borescope survey to check the cavity's condition before installation, since insulating a cavity with existing damp or debris can make problems worse, not better.

Price the pre-installation survey as its own step instead of assuming every property is a straightforward candidate. This is where genuine problems get caught before they become an insulation job gone wrong. It also protects you from being blamed for damp or condensation that was actually caused by installing insulation into an unsuitable cavity.

Ventilation is the detail most likely to get skipped in a quote and most likely to cause a complaint later. Over-insulating a property without adequate ventilation is a real, well-documented cause of condensation and mould. A short note explaining what ventilation is included or recommended alongside the insulation work is a genuine technical safeguard, not merely covering yourself.

Government schemes like ECO4 or the Great British Insulation Scheme can significantly reduce the customer's net cost, but eligibility depends on their specific circumstances and isn't guaranteed. State clearly whether the price shown assumes a grant has been confirmed or is the full cost before any scheme discount, so there's no confusion on the final invoice.

Frequently asked questions

A borescope check confirms the cavity is in suitable condition. Insulating a cavity with existing damp or debris can make problems worse rather than better.

Over-insulating without adequate ventilation is a known cause of condensation. A proper job includes a note on ventilation, not just the insulation material itself.

This should be stated explicitly — schemes like ECO4 depend on individual eligibility, so the quote should be clear whether it assumes a grant or shows the full pre-grant cost.
