SECR reporting for property and real estate — UK guide

If you're a UK property owner, investor, landlord, REIT or asset manager hitting the SECR thresholds (£36M+ turnover, £18M+ balance sheet, or 250+ employees), this guide covers what you have to file and the boundary questions that determine the answer.

SECR challenges specific to property and real estate

Four problems generic SECR templates don't handle for property businesses:

1. Landlord-controlled vs tenant-controlled energy. Your tenants pay their own utility bills (tenant-controlled). The landlord pays for common areas, plant rooms and void periods (landlord-controlled). Only the landlord-controlled energy is in scope under the operational-control approach — but you have to document the boundary, by lease type, with evidence.
2. Void period emissions. When a unit is vacant, the landlord pays the utility bills and the emissions belong to the landlord even though no one is using the space. Many first-time filers miss this, then their auditor adds 5–15% to scope 2.
3. Service charge energy recovery muddies the data. Many leases let landlords recharge tenants for common-area energy via the service charge. The emissions still belong to the landlord under operational control, but the cost data sits in a service-charge reconciliation, not the landlord's direct utility account.
4. The intensity ratio is m² and BREEAM-aligned, not turnover-based. Property investors compare emissions per m² of GIA (gross internal area) or per m² of NLA (net lettable area). Reporting tCO₂e per £1M turnover, as the SECR default suggests, is meaningless to your lender, REIT investor or BREEAM-In-Use assessor.

Typical scope 1 emissions in property

Scope 1 for a property owner is usually small but specific:

• Natural gas — landlord-controlled boilers and CHP (district heating from a landlord plant room, common-area heating)
• Diesel — back-up generators in commercial buildings
• Diesel and petrol — owned vehicle fleet (asset managers, facilities teams, mobile maintenance crews)
• F-gas refrigerant leakage — landlord-controlled chillers, comfort cooling in common areas, lift hydraulics, fan-coil refrigerants. Big-floorplate office and retail assets can have 50+ kg/year of refrigerant top-up
• LPG — off-mains heating for some rural assets

A landlord with a fully NIA-let portfolio (no common areas) might have near-zero scope 1. A REIT with hundreds of multi-let buildings, district heating networks and chilled-water plant has scope 1 in the thousands of tCO₂e.

Typical scope 2 emissions in property

Scope 2 for property is overwhelmingly landlord-controlled grid electricity:

• Common-area lighting and small power
• Lifts and escalators
• HVAC plant — chillers, AHUs, ventilation, fan-coils
• Plant-room electricity (pumps, controls, BMS)
• Void unit utility supplies — when tenants leave, landlord-paid bills
• External lighting, car park lighting

For multi-let portfolios, the market-based vs location-based question matters at the asset level — some assets have green tariff procurement, others don't. SECR allows you to report whichever (or both); customers and investors increasingly want both.

Scope 3 considerations for property

Scope 3 is voluntary for SECR but increasingly material for property:

• Category 1 — Purchased goods and services — consultants, agents, fit-out contractors, FM services
• Category 2 — Capital goods — this is the big one for property: embodied carbon in new construction, refurbishment, fit-outs and major capital works. UKGBC's Net Zero Whole Life Carbon Roadmap pushes the sector to disclose this voluntarily
• Category 6 — Business travel and 7 — Employee commuting
• Category 11 — Use of sold products — for buy-to-sell developers, the in-use energy of the building once sold
• Category 13 — Downstream leased assets — tenant emissions in landlord-owned buildings. Some asset managers voluntarily disclose this even though SECR doesn't require it; investors and lenders increasingly do (especially under the Sustainability Disclosure Requirements / SDR framework)
• Category 15 — Investments — for funds and REITs, financed emissions in the property portfolio

Tenant-paid energy is technically not in your scope 1 or 2 under operational control, but appears as scope 3 category 13 if you choose to disclose it. The investor expectation (BBP, GRESB) is to disclose both.

Common mistakes property companies make

1. Counting tenant-controlled energy as scope 1 or 2 — only landlord-controlled energy is in scope under the operational-control approach
2. Missing void period emissions — landlord pays the bill, emissions belong to landlord, even with no occupant
3. Reporting service-charge-recharged common area energy in tenant scope — operational control sits with the landlord regardless of who pays
4. Using tCO₂e per £1M turnover instead of tCO₂e per m² (GIA or NLA) — looks naive to property investors
5. Forgetting district heating from a landlord plant room as a scope 1 source
6. Ignoring F-gas leakage from landlord-controlled chillers and lift refrigerants
7. Not separating like-for-like vs portfolio-change emissions when reporting year-on-year — acquisitions, disposals and refurbishments must be split out for the narrative to read sensibly

Trade body context — BPF, BBP, GRESB, UKGBC

The British Property Federation (BPF), Better Buildings Partnership (BBP) and UKGBC all publish sector guidance on SECR-aligned reporting. The BBP Real Estate Environmental Benchmark (REEB) is the de facto UK property emissions benchmark — feature your performance against REEB in the narrative section.

GRESB (Global Real Estate Sustainability Benchmark) is the dominant institutional investor disclosure. If you report to GRESB, your SECR submission should be consistent — auditors and investors will compare. UKGBC's Net Zero Whole Life Carbon Roadmap defines the embodied carbon and operational carbon trajectory the UK property sector has committed to.
