A commercial EPC is more than its A–G grade. Use the accompanying recommendations to ask better questions before you budget for improvements. This guide is written for practical decision-making and links to the sources used for verification.
The grade is only page one of the conversation
A small office receives a commercial EPC and the owner immediately asks which single upgrade will move it up a band. The accompanying recommendations report is a better starting point than a guess about LEDs or a new boiler. Government guidance says it lists measures to improve the assessed building, with indicative payback categories.
First confirm the report belongs to the exact unit being managed. Note its issue date, assessed area and the building services the assessor saw. A recommendation for an earlier layout may not describe a space after a tenant fit-out. If information appears wrong, ask the accredited assessor to explain it before using the report as an investment plan.
Read the payback headings carefully
The non-domestic EPC guide groups recommendations into short payback (under three years), medium (three to seven), long (over seven), and other assessor recommendations. These are modelled indications, not a contractor's fixed-price quotation or a guarantee of savings. An item can be sensible for a long lease yet impractical if equipment is near the end of its life or a tenant controls the fit-out.
Separate measures the occupier can operate, such as controls, from capital work to the fabric or plant. Then ask who owns each system, who pays the bill and who has authority to alter it. A landlord–tenant discussion at this stage is often more useful than commissioning work from the headline grade alone.
- Match each suggestion to the equipment actually present
- Get a site-specific cost and savings assessment before committing
- Check lease responsibility, access and planned refurbishment timing
Turn the report into a sensible brief
Request quotations for the most relevant measures and ask suppliers to state assumptions, disruption and commissioning needs. A commercial EPC is an asset rating, not an electrical safety report, plant-condition survey or measured energy audit. If the premises is rented, review the current non-domestic minimum-efficiency rules separately before making a letting decision.
CertifyEPC can arrange a commercial EPC for London premises. Share the postcode, floor area, plans and heating or cooling details so the accredited assessor can scope the right unit. Once lodged, use the certificate and recommendations as evidence for a properly costed next step—not as a substitute for one.
