How much does a commercial EPC cost in 2026?
Most UK commercial EPCs cost between £250 and £900. Small, simple units sit at the bottom of that range; air-conditioned offices in the middle; and complex Level 5 buildings needing dynamic simulation start around £1,200 and can pass £2,500. Here is what actually moves the number.
Typical 2026 prices by building type
| Building | Typical level | Typical fee (ex VAT) |
|---|---|---|
| Small shop or office suite (under 250 m²) | Level 3 | £250–£350 |
| Industrial unit / small warehouse | Level 3 | £280–£450 |
| Air-conditioned office, 500–2,000 m² | Level 4 | £450–£750 |
| Retail with catering / restaurant / gym | Level 4 | £500–£900 |
| Hotel or care home | Level 4 | £600–£1,200 |
| Complex building requiring DSM | Level 5 | £1,200–£2,500+ |
Ranges reflect quotes we see across the UK market in 2026. London and the South East typically price 10–20% above the northern cities.
The five factors that set your price
- Floor area and zoning. Assessors model the building zone by zone. A 400 m² open-plan unit is one job; a 400 m² building cut into fourteen treatment rooms is a different job at the same floor area.
- Assessment level. The jump from Level 3 to Level 4 typically adds 40–80% to the fee; Level 5 DSM work is a different cost category altogether because the modelling takes days rather than hours.
- Documentation quality. Drawings, O&M manuals and plant schedules cut survey and modelling time. No documentation means more measurement on site and more conservative defaults — slower and usually a worse rating.
- Location and access. Out-of-the-way sites carry travel time. Restricted access (occupied secure premises, plant rooms needing escorts) adds survey hours.
- Urgency. Standard turnaround is two to four working days post-survey for SBEM work. Genuine 48-hour turnarounds exist but typically carry a 25–50% premium.
Cost in context: the certificate vs the consequences
An EPC fee is small against what hangs off it. Letting a sub-E property without an exemption exposes a landlord to MEES penalties of up to £150,000 per property at the top of the rateable-value scale — details in our MEES guide. On transactions, a missing or expired certificate delays completion; on refinancing, a poor rating now feeds directly into lending terms. The economic decision is rarely "cheapest certificate" and almost always "accurate certificate, evidenced properly, at the right level" — our guide to choosing an assessor explains the checks.
How to keep the fee down legitimately
Three things genuinely reduce quotes. Gather documentation before the survey — even a marketing floor plan helps. Batch buildings into a single instruction where you can. And book with reasonable lead time, because urgency premiums are the most avoidable cost in the whole process. What does not help: choosing an assessor purely on price for a building near the E/F boundary, where conservative defaults can tip the rating the wrong side of lettable.
