No, a Domestic Energy Assessor carries out a strictly non-intrusive, visual inspection of your property without causing any damage or disruption to the building fabric.

They will not drill into your walls, lift securely fixed floorboards, or move heavy furniture. They simply observe, measure, and photograph easily accessible areas. You can relax knowing your home—and your carefully tended indoor plants—will remain completely undisturbed while the assessor meticulously gathers the facts they need.

RdSAP 10 is the updated, official UK government calculation methodology that Domestic Energy Assessors use to determine an existing home's energy efficiency rating.

Introduced as the new standard, it collects far more precise data regarding your heating, ventilation, and solar energy systems than previous versions, ensuring a highly accurate and factual reflection of your home's true environmental performance.

If your rental property receives an F or G rating on its Energy Performance Certificate (EPC), it does not meet the Minimum Energy Efficiency Standards (MEES) required by law in the UK. Here's what happens and what you need to do:

Legal Implications

1. Illegal to Rent Out:

   • Properties with an EPC rating of F or G cannot legally be rented out unless an exemption is registered. This applies to both new and existing tenancies.

2. Penalties for Non-Compliance:

   • Landlords who rent out properties below the minimum standard without an exemption may face fines of up to £5,000 per property.

Steps to Take

1. Improve the Energy Efficiency:

   • You must make improvements to bring the property up to at least an E rating. Common upgrades include:
     • Installing loft or wall insulation.
     • Upgrading to energy-efficient windows or doors.
     • Replacing an old boiler with a modern, energy-efficient model.
     • Adding renewable energy sources like solar panels.

2. Apply for Funding or Grants:

   • Check if you qualify for government schemes or grants to help cover the cost of energy efficiency improvements.

3. Register an Exemption (if applicable):

   • In some cases, you may be able to register an exemption on the PRS Exemptions Register. Examples include:
     • If the cost of improvements exceeds £3,500 (including VAT).
     • If the property is a listed building and changes would alter its character.
     • If you’ve made all possible improvements but still cannot achieve an E rating.

Impact on Tenants

• Higher Energy Bills: Properties with poor energy efficiency are more expensive to heat, which can lead to tenant dissatisfaction.
• Difficulty Attracting Tenants: Tenants are increasingly prioritising energy-efficient homes to save on utility costs.

Next Steps

• Arrange for a qualified Domestic Energy Assessor to re-evaluate the property after making improvements.
• Ensure compliance before marketing or renewing any tenancy agreements.
