EPC Assessor

Become a Domestic Energy Assessor and supply EPCs to estate agents

Become a Domestic Energy Assessor and supply EPCs to estate agents.

As an EPC Assessor, your day-to-day work involves conducting energy assessments of residential properties, analysing energy efficiency, and producing Energy Performance Certificates (EPCs) for clients. You’ll schedule appointments with homeowners, collect data, and report findings. This role requires attention to detail and a thorough understanding of current energy regulations, making it a solid service-based business for those looking to enter the market.

With the UK government aiming for net-zero emissions by 2050 and increasing pressure on property owners to improve energy efficiency, now is the perfect time to start this business. The demand for EPCs is rising as landlords and homeowners prepare for stricter energy regulations, making your services increasingly sought after in a competitive property market.

Ideal founders for this venture are individuals with a keen interest in energy efficiency and sustainability. You’ll need to invest time in obtaining your Domestic Energy Assessor qualification and building relationships with estate agents. Expect to dedicate around 10-15 hours a week to get your business off the ground, focusing initially on marketing and client outreach.

In 12-24 months, you could expand your client base significantly, potentially earning between £25,000 to £40,000 annually by securing contracts with multiple estate agents. As your reputation grows, you might consider hiring additional assessors or expanding your services to include energy consultancy, increasing your revenue streams.

Why now

The UK property market is under pressure to meet new energy efficiency standards, particularly with the introduction of Minimum Energy Efficiency Standards (MEES). This creates a growing need for qualified EPC Assessors as landlords and sellers seek to comply with regulations.

Who pays you

Your primary customers are estate agents who require EPCs for properties they are selling or renting. Additionally, landlords and homeowners looking to improve their property's energy efficiency will also seek your services.

UK market

The UK EPC market is projected to grow as energy efficiency becomes a priority for property owners. With over 29 million residential properties in the UK, the potential market for EPCs remains substantial, especially as more properties require assessments to comply with new legislation.

Revenue & pricing

You will charge estate agents and homeowners between £40 and £100 per EPC, depending on the complexity and size of the property. Additional services, such as consultations on energy improvements, can provide further income.

  • Standard EPC for a 1-2 bedroom flat: £60
  • EPC for a 3-4 bedroom house: £80
  • Commercial property EPC: £100
  • Consultation on energy improvements: £50 per hour
Realistic year one: In your first year, you might realistically earn between £3,000 and £7,000, depending on the number of clients you secure and your marketing efforts. Profit margins will improve as you establish your business and reduce initial costs.
