Professional Services SECR: Office-Based Business Guide

For professional services firms across the UK—from law practices and accountancy firms to consultancies and financial advisors—SECR compliance might seem like an unexpected regulatory burden. After all, you're not running a factory or operating heavy machinery. But if your firm meets the size thresholds (50+ employees, £36M+ turnover, or £18M+ balance sheet), SECR reporting is mandatory, regardless of your industry sector.

The good news? Office-based businesses typically have simpler emissions profiles than manufacturing or logistics companies, making SECR compliance more straightforward once you understand the process. This comprehensive guide walks you through everything professional services firms need to know about meeting their SECR obligations.

Understanding SECR for Office-Based Businesses

The Streamlined Energy and Carbon Reporting (SECR) regulations came into force in April 2019, requiring qualifying UK companies to report their energy use and carbon emissions in their annual Directors' Report filed with Companies House.

Who Must Comply?

Your professional services firm must comply with SECR if it meets two or more of these criteria:

• 50 or more employees
• Annual turnover of £36 million or more
• Annual balance sheet total of £18 million or more

This catches most mid-sized and large professional services firms, including:

• Law firms with multiple offices
• Accountancy and audit practices
• Management consultancies
• Marketing and PR agencies
• Architectural and engineering firms
• Financial services and wealth management companies
• IT consultancies and software houses
• Corporate service providers

Even if you operate from relatively modest office spaces, the employee and revenue thresholds mean many successful professional services businesses fall within scope.

What Office-Based Businesses Must Report

SECR requires you to disclose three key metrics in your annual Directors' Report:

1. Energy Consumption

Report your total energy use in kilowatt-hours (kWh) from:

• Electricity consumed in all UK offices
• Natural gas used for heating and hot water
• Transport fuels for company vehicles (if applicable)

For most professional services firms, electricity and gas will account for the vast majority of energy consumption. If you don't operate company vehicles, you can exclude transport entirely.

2. Greenhouse Gas Emissions

Calculate and report your carbon emissions in tonnes of CO2 equivalent (tCO2e), covering:

• Scope 1 emissions: Direct emissions from sources you control (natural gas heating, company vehicles)
• Scope 2 emissions: Indirect emissions from purchased electricity

Use the official UK Government conversion factors published annually by DEFRA. These factors convert your energy consumption into carbon emissions.

3. Intensity Ratio

Express your emissions relative to a business metric that makes sense for your operations. For professional services firms, common intensity ratios include:

• Emissions per employee (tCO2e per FTE)
• Emissions per square foot of office space
• Emissions per £ revenue (for comparing year-on-year efficiency)

Most office-based businesses choose emissions per employee as this normalizes for headcount growth and allows meaningful year-on-year comparisons.

Calculating Your Office Emissions: Step-by-Step

Step 1: Gather Your Energy Bills

Collect 12 months of energy bills covering your reporting period (typically your financial year). You'll need:

• Electricity bills for all UK office locations
• Gas bills for all UK office locations
• Fuel receipts for company vehicles (if applicable)

Pro tip for multi-office firms: If you have service charge arrangements where the landlord pays utilities, request energy consumption data from your property manager. Most commercial leases require landlords to provide this information upon request.

Step 2: Extract Consumption Data

From each bill, record:

• Billing period dates
• Total kWh consumed (look for this on every electricity and gas bill)
• Supply type (electricity, natural gas, etc.)

Watch out for estimated readings: Some bills show estimated rather than actual meter readings. Where possible, use bills with actual readings or request corrected invoices from your supplier.

Step 3: Apply UK Government Conversion Factors

Download the latest UK Government GHG Conversion Factors spreadsheet (updated annually).

For office-based businesses, you'll primarily use:

• Electricity: Grid electricity conversion factor (varies by year; approximately 0.193 kgCO2e/kWh for 2025)
• Natural gas: Gas conversion factor (approximately 0.203 kgCO2e/kWh for 2025)

Calculation example for a law firm:

Annual electricity consumption: 150,000 kWh
× Electricity conversion factor: 0.193 kgCO2e/kWh
= 28,950 kg CO2e
= 28.95 tonnes CO2e (Scope 2)

Annual gas consumption: 80,000 kWh
× Gas conversion factor: 0.203 kgCO2e/kWh
= 16,240 kg CO2e
= 16.24 tonnes CO2e (Scope 1)

Total emissions: 45.19 tonnes CO2e

Step 4: Calculate Your Intensity Ratio

Divide your total emissions by your chosen metric:

Total emissions: 45.19 tonnes CO2e
÷ Number of employees: 75 FTE
= 0.60 tonnes CO2e per employee

This intensity ratio becomes your baseline for tracking improvements year-over-year.

Common Emission Sources for Professional Services

Understanding where your emissions come from helps identify reduction opportunities:

Major Sources (typically 70-90% of total)

Electricity consumption:

• Office lighting (especially in older buildings with halogen/fluorescent)
• IT equipment (servers, computers, monitors)
• Air conditioning and cooling systems
• Office equipment (printers, photocopiers, kitchen appliances)

Natural gas heating:

• Space heating (particularly significant in older, poorly insulated buildings)
• Hot water systems

Minor Sources (typically 10-30% of total)

Company vehicles (if applicable):

• Pool cars for client visits
• Partner/director company cars
• Delivery vehicles for document transport

Other potential sources:

• Backup generators (emergency power)
• On-site data centers or server rooms with dedicated cooling

What You DON'T Need to Include

SECR has clear boundaries. For office-based businesses, you can exclude:

• Employee commuting: Staff travel to/from work doesn't count
• Business travel in personal vehicles: If employees use their own cars and claim mileage, this doesn't count (though it may be required for broader carbon footprinting)
• Air travel and rail travel: Not required under SECR (though increasingly relevant for voluntary carbon reporting)
• Purchased goods and services: Your suppliers' emissions aren't your SECR responsibility
• Waste disposal: Not included in SECR scope

This makes SECR relatively straightforward for professional services compared to more comprehensive carbon accounting frameworks.

Energy Efficiency Measures for Office-Based Firms

SECR requires you to describe the "energy efficiency action taken in the financial year." This doesn't need to be extensive, but you must demonstrate some consideration of energy management.

Quick Wins for Professional Services Firms

Lighting upgrades:

• Replace halogen/fluorescent with LED lighting (typical payback: 2-3 years)
• Install motion sensors in meeting rooms, toilets, and corridors
• Maximize natural light and adjust artificial lighting zones

IT and equipment:

• Enable power management on all computers (sleep mode after 15 minutes)
• Replace old desktop computers with energy-efficient laptops
• Consolidate printers and photocopiers (newer models use 30-50% less energy)
• Switch to cloud services instead of running on-premise servers

Heating and cooling:

• Install smart thermostats with time scheduling
• Set heating to 19°C (recommended by HSE for office environments)
• Service HVAC systems annually to maintain efficiency
• Improve insulation and draught-proofing in older buildings

Behavioral changes:

• "Switch off" campaigns for lights and equipment
• Working from home policies (reduces office energy demand)
• Encourage use of stairs instead of lifts where practical

Example Energy Efficiency Narrative

Here's how a consultancy might report their energy efficiency actions:

"During the financial year, the company upgraded lighting to LED across all three office locations, reducing electricity consumption by approximately 15%. We implemented power management settings on all workstations and consolidated print devices from 20 to 8 energy-efficient multifunction units. Our hybrid working policy, with staff in the office 3 days per week on average, has reduced overall building energy demand. We also conducted an energy audit of our London headquarters, identifying opportunities for improved HVAC controls which will be implemented in the coming year."

This demonstrates meaningful action without requiring massive capital investment.

Multi-Office Compliance Challenges

Professional services firms often operate across multiple locations, which introduces specific SECR complexities:

Challenge 1: Decentralized Energy Data

Problem: Different offices may have different landlords, suppliers, and billing arrangements.

Solution:

• Appoint an internal SECR coordinator to centralize data collection
• Create a standardized spreadsheet for all offices to submit energy data
• Set clear internal deadlines (e.g., 6 weeks before Directors' Report is due)
• For serviced offices, request consumption data from facility managers in advance

Challenge 2: Shared Buildings and Service Charges

Problem: Many professional services firms lease space in multi-tenant buildings where energy is included in service charges.

Solution:

• Request sub-metered data from your landlord or property manager
• If not available, ask for an apportionment based on your floor space
• Some leases require landlords to provide energy data on request—check your lease terms
• For serviced offices (e.g., Regus, WeWork), request consumption data specific to your occupancy

Challenge 3: Short-Term Leases and Office Moves

Problem: If you moved offices during the reporting period, how do you account for partial occupancy?

Solution:

• Include energy consumption for all premises occupied during the reporting period
• Pro-rate energy data based on actual months of occupancy
• Note any significant changes in your SECR narrative (e.g., "Following relocation to a more energy-efficient building in November 2025, we anticipate reduced emissions in future reporting periods")

SECR Deadlines and Filing Process

Key Deadlines

SECR disclosures must be included in your annual Directors' Report filed with Companies House. The deadline depends on your company structure:

• Private limited companies: 9 months after financial year-end
• Public limited companies: 6 months after financial year-end

For example, if your financial year ends on 31 December 2025:

• Private limited companies: Deadline is 30 September 2026
• Public limited companies: Deadline is 30 June 2026

Important: These are legal deadlines. Companies House can impose penalties for late filing, starting at £150 and escalating to £7,500+ for persistent delays.

How to File

SECR information must be included in your Directors' Report, which forms part of your annual accounts submitted to Companies House:

1. Include SECR disclosures in the Directors' Report section of your annual accounts (typically 1-2 pages)
2. File accounts via Companies House WebFiling service or through your accountant
3. Publish on your website (if you're a quoted company) or make available to shareholders

Most professional services firms work with their accountants or company secretaries to ensure SECR information is correctly formatted and included in the statutory accounts.

What Happens if You Don't Comply?

Penalties for non-compliance:

• Companies House can reject your accounts if SECR information is missing or inadequate
• You may face reputational damage and stakeholder scrutiny
• In extreme cases, directors can be held personally liable for non-compliance with statutory reporting requirements

However, there are no specific SECR-only fines. The enforcement mechanism is through the existing Companies Act framework for statutory reporting.

Outsourcing vs. In-House SECR Compliance

Professional services firms face a choice: manage SECR in-house or outsource to consultants or automated platforms.

Traditional Consultant Route

Typical cost: £15,000 - £25,000 Timeline: 6-10 weeks Pros: White-glove service, expert advice Cons: Expensive, slow, recurring annual fees

Environmental consultants will gather your data, perform calculations, and draft your SECR disclosure. This works well for firms with complex operations but is overkill for straightforward office-based businesses.

In-House Approach

Typical cost: Internal staff time Timeline: Variable (often 2-4 weeks) Pros: Free (if you have capable staff), builds internal knowledge Cons: Time-consuming, risk of errors, staff may lack expertise

If you have a knowledgeable finance team or facilities manager, you can manage SECR internally using government guidance and spreadsheets. However, most professional services firms find this diverts valuable billable time.

Automated Platform Route

Typical cost: £1,999 (Comply Carbon) Timeline: 10 minutes to upload bills, instant report generation Pros: Fast, affordable, accurate, automated calculations Cons: Less hand-holding than consultants (though most firms don't need it)

Platforms like Comply Carbon offer the middle ground: you upload energy bills, AI extracts the data, calculations happen automatically using official conversion factors, and you receive a compliant SECR disclosure ready to include in your Directors' Report.

For most office-based professional services firms, this is the optimal approach—significantly cheaper than consultants, faster than in-house, and with zero risk of calculation errors.

Case Study: London Law Firm

Firm profile: 85 employees, two London offices, £42M turnover

SECR challenge: First year of compliance, no prior carbon reporting experience, partners concerned about consultant fees

Approach: Used Comply Carbon automated platform

Results:

• Uploaded 24 energy bills (12 months × 2 offices) in under 5 minutes
• Platform automatically calculated: 89.4 tCO2e total emissions
• Intensity ratio: 1.05 tCO2e per employee
• Generated compliant SECR disclosure including energy efficiency narrative
• Total cost: £1,999 (saved £18,000+ vs. consultant quotes)
• Time: 10 minutes vs. projected 6-8 weeks with consultant

Partner feedback: "We were dreading SECR compliance as a regulatory burden. Comply Carbon made it trivial—faster and cheaper than we imagined possible. We'll definitely use it again next year."

Preparing for Future Climate Reporting

While SECR is your immediate legal obligation, forward-thinking professional services firms should be aware of evolving climate disclosure requirements:

TCFD (Task Force on Climate-related Financial Disclosures)

Currently applies to premium-listed companies and large private companies with 500+ employees and £500M+ turnover. However, TCFD recommendations are increasingly expected by:

• Major clients (particularly public sector and large corporates)
• Investors and lenders
• Tender processes for government contracts

SECR compliance is a strong foundation for TCFD, as it establishes your carbon accounting processes.

Scope 3 Emissions

SECR only requires Scope 1 and 2 (direct and purchased electricity). But clients and stakeholders increasingly want Scope 3 transparency:

• Business travel (flights, rail, taxis)
• Employee commuting
• Purchased services (cloud computing, professional services you procure)

Many professional services firms are voluntarily measuring Scope 3 to demonstrate climate leadership and meet client expectations.

Science-Based Targets

Setting emissions reduction targets aligned with climate science (limiting global warming to 1.5°C) is becoming a competitive differentiator in professional services, particularly when bidding for work with sustainability-conscious clients.

Getting SECR right now positions you well for these emerging requirements.

Key Takeaways for Professional Services Firms

• SECR applies to most mid-sized and large professional services firms (50+ employees, £36M+ turnover, or £18M+ balance sheet)
• Office-based businesses have relatively simple emissions profiles: mainly electricity and gas, with straightforward calculations
• Energy efficiency actions don't need to be extensive: LED lighting, IT power management, and smart heating controls are sufficient
