Energy audit

Energy audit — Tonga

Insulating at random often means spending a lot for little. The audit identifies where the heat actually escapes, sets the order of works that pays off most, and avoids money spent in the wrong place. On Helplease, you describe your needs and the workers offering this service in Tonga are notified of your request.

What the service covers

• identifying heat loss and thermal bridges;
• analysing consumption and equipment;
• prioritising works by effectiveness;
• estimating the expected gains;
• written report with recommendations.

Depending on the agreement, the service can include the visit, the measurements, analysis of the bills, prioritisation of the works, a written report and time to explain the conclusions.

Key points

Estimates and grants

An audit or a study gives estimates, not guarantees: real savings depend on usage, climate and the quality of the work. No savings figure can be promised in advance. The conditions for grants and support schemes change regularly and must be checked with the relevant bodies before committing to works, never on the word of a doorstep seller alone.

Quote and vigilance in an emergency

An emergency call-out is still a service that can be discussed: ask for the estimated amount before the work starts, a detailed invoice at the end, and refuse to sign a document you have not read. Be wary of anyone piling up unjustified replacements, demanding immediate cash payment or refusing to put their estimate in writing. The worker must be qualified for the work concerned.

What affects the price

• nature of the work;
• equipment and parts;
• difficulty of access;
• length of the job;
• number of units involved.

The rate is agreed with the worker based on these elements.
