How Much Does an EPC Cost in London? 2026 Pricing

For a typical one- to three-bedroom London flat or terrace, expect £80–£100 from a reputable Elmhurst-accredited assessor. Four-plus-bedroom houses sit at £100–£150. Studios and very small one-beds occasionally come in at £75. Anything advertised at £35–£50 in central London is either a loss-leader (the assessor will upsell) or a sign of a non-compliant lodgement risk.

Five reasons: accreditation scheme overhead (Elmhurst, Stroma and Quidos charge different lodgement fees), travel and ULEZ absorption, assessor experience (a DEA with 10 years of London stock recognises construction periods faster than a new entrant), volume rebates from accreditation bodies, and whether the assessor carries professional indemnity cover. The last one is the most important — a non-PI assessor is cheaper but gives you no recourse if the EPC is later found incorrect at sale or remortgage.

The on-site survey takes 30–60 minutes for a flat, 60–90 minutes for a house, depending on access and roof/loft inspection requirements. Lodgement and PDF issue is normally the same working day if the survey completes before 14:00 — so you can have an EPC certificate in your inbox within 4 hours of the assessor arriving.

London assessors absorb three cost layers that regional assessors do not: ULEZ daily charge (£12.50 per day for older vehicles), parking and congestion costs, and the time penalty of cross-borough travel. The result is a £10–£25 premium versus the national average. A £69 EPC in the Midlands is the genuine equivalent of around £85 in London — so an £80–£100 London quote is comparable, not expensive.

They exist but carry real risk. Common patterns: assessor is not Elmhurst/Stroma/Quidos accredited (illegal to lodge); the certificate is lodged in a misnamed property address (rejected at conveyancing); the assessment is "drive-by" or desk-based with no actual measurement (re-assessment required on sale); no PI cover (no recourse if the EPC is wrong). Always verify the EPC reference number on gov.uk/find-energy-certificate before paying.

No. An EPC is valid for 10 years from the date of issue. You only need a new one if (a) the old one has expired, (b) you have made significant improvements and want the rating updated for MEES or marketing, (c) the conveyancing solicitor or lender has specifically requested a current EPC at the point of sale, or (d) you are renewing a tenancy and the EPC has lapsed during the previous let.

RdSAP (Reduced Data SAP) is used for existing dwellings — the assessor measures the property and infers fabric U-values from age and construction. Full SAP is used for new-build dwellings and major conversions, where actual design data (insulation specs, U-values, air-permeability test results) is fed in. RdSAP costs £79–£150 in London; SAP for new builds is typically £200–£500 because it needs the full SAP10 calculation pre- and post-construction.

Commercial EPCs use the SBEM (Simplified Building Energy Model) calculation rather than RdSAP, and are assessed by a Non-Domestic Energy Assessor (NDEA) at Levels 3, 4 or 5 depending on building complexity. Level 3 (small offices, retail units, no air-conditioning) starts at £225. Level 4 (medium with HVAC) is £495+. Level 5 (large or bespoke heating/cooling) is custom — typically £1,000+. See our commercial EPC page for the full breakdown.

Yes. Most landlord and selling profiles benefit from bundling. EPC + Floor Plan saves 20% on the floor plan (same visit, same measurement). EICR + CP12 + EPC landlord pack saves 10–15% versus three separate visits. HMO + FRA + EPC bundle saves 18%. We hold the renewal calendar so each certificate triggers a reminder 60 days before expiry.

The EPC is not lodged on the central register until payment is received, so you cannot use a refused EPC for sale or letting purposes. We do not require upfront payment — you pay after the certificate is issued — but if the assessment was completed and you choose not to pay, the assessor retains the survey data and the EPC remains undocumented. We invoice the same day and the property cannot be marketed until lodgement clears.
