For engineers creating records, not booking an inspection
Looking for gas certs online for your business? Essential is software used by engineers to record their own work. It does not sell a gas inspection to landlords or arrange a Gas Safe registered engineer.
Choose the landlord gas safety record for the appropriate inspection, the homeowner record for owner-occupied work, or a service, installation or specialist record for that job. Preview the actual document before starting.

Records for the work you carry out
The Essential package includes natural gas, LPG, unvented hot water and renewable-heating record modules. Gas records cover landlord and homeowner inspections, service and repair, installation and commissioning, warning notices, visual inspections and non-domestic work. Oil records are currently deferred.
Each record asks for the information relevant to that document. Repeatable appliance sections keep equipment details, readings and findings together, rather than treating every job as the same form.
Review first. Sign last.
Complete the questions and review the recorded answers before issuing the document. You can return to a question and correct it before signing. The customer acknowledgement is optional; the engineer signature is required before a certificate can be issued or its PDF created.
Changing the answers invalidates the previous review and signatures. The engineer must review and sign the changed record again. This helps keep the issued PDF tied to the information that was actually confirmed.
Company-branded PDFs and saved work
Your business name, contact information and selected engineer details appear on the record. The standard certificate layouts use A4 pages, with additional space where the document needs it. Related warnings retain their references alongside the job record.
Free accounts can save work. Certificate issuance and PDF/report downloads use your Essential subscription or an applicable permanent free-access grant. You can keep an editable backup of your own workspace data.
IGEM/UP/1B calculations alongside your records
The independent IGEM/UP/1B Calculator is free to use online without an account. It provides gas installation-volume calculations and a pressure-drop comparison using the selected gas, gauge and test configuration. A free account saves results; the Essential package adds numbered calculator reports and PDF downloads.
Original Essential work records are not official scheme certificates. The software does not replace the competent engineer, applicable current standards, manufacturer instructions or any required scheme documents.

Before you choose
Can I create a gas safety certificate online?
Essential lets an appropriately competent engineer record an actual job online, review and sign the findings, and create the A4 PDF with an active trial, subscription or access grant. Signing up does not qualify someone to carry out gas work.
What can I do without paying?
Use the free calculators and save supported drafts or IGEM calculator results with a free account. Numbered customer documents and PDF/report downloads require the Essential package or an applicable access grant. An eligible company can also start a seven-day package trial without a card. The trial must be started explicitly after email confirmation and company setup.
Where can I inspect the output?
Open the clearly marked fictional PDF sample on this page. It uses the actual Essential layout. The engineer remains responsible for the work and the accuracy of the record.
