Why Choose a Quality EPC Assessor?

Not All EPCs Are Equal — and the Difference Can Cost You

Too often we are called in to carry out a new EPC assessment on a property where the existing certificate simply does not reflect the property’s true performance. The errors we find are not always subtle. We regularly encounter certificates where:

Building control evidence has not been checked — extensions, loft conversions, and structural alterations all have building control records that can confirm insulation and construction details. An assessor who does not look these up will default to software assumptions, which are almost always worse than the reality.
Cavity wall insulation has not been verified — many properties had cavity wall insulation installed under government grant schemes in the 1990s and 2000s. The evidence is often in building control or local authority records. An assessor who does not check will assume the cavity is empty — potentially costing the property owner one or two EPC bands.
Loft insulation depth has been estimated rather than measured — the difference between 100mm and 270mm of loft insulation is significant in RdSAP 10. Measurement takes thirty seconds. Guessing costs your client points.
Property type has been incorrectly recorded — end-of-terrace vs mid-terrace, semi-detached vs detached — these classifications directly affect the heat loss calculation. Getting them wrong produces an inaccurate rating regardless of everything else.
Measurements are wrong — external measurements form the basis of the floor area calculation which underpins the entire assessment. Errors here cascade through the whole certificate.
Smart heating controls have not been recorded — under RdSAP 10, a smart thermostat such as a Hive or Nest can add a vital point to the score. That single point can be the difference between Band D and Band C — potentially saving a landlord thousands of pounds in unnecessary structural improvements.

What a Thorough EPC Assessment Actually Looks Like

At Hive EPCs, every assessment follows the same meticulous process:

We check building control records for extensions, loft conversions, and insulation improvements before we arrive or at the property
We measure every room and the external footprint of the property — we never estimate
We verify insulation depths in the loft personally — we do not assume
We identify and record all heating controls including smart thermostats, programmers, and TRVs
We photograph evidence of improvements — glazing certificates, insulation installation records, boiler manuals
We correctly classify the property type based on physical inspection, not assumption
We explain the certificate, the score, and the improvement pathway to you after every assessment

This level of care takes longer than a twenty-minute walkthrough. It produces a more accurate certificate — and for landlords targeting Band C, accuracy can be the difference between a simple heating control upgrade and a £10,000 wall insulation project.

We Are Trusted Because We Get It Right

The majority of our work in Kent comes through word of mouth and referrals from property professionals. Estate agents, letting agents, and property managers send their clients to us because they know the certificate will be accurate, the assessor will be professional, and the service will reflect well on them.

We treat every property with respect — we remove our shoes where possible, we work quietly and efficiently, and we leave the property exactly as we found it. We are available after the assessment to answer questions about the certificate, explain improvement options, and advise on the most cost-effective route to a higher band.

That after-service support is rare in this industry. For landlords planning improvements ahead of the 2030 MEES deadline, being able to call and ask “if I install X, what will my new rating be?” — and get an honest, technically accurate answer — is worth more than saving £10 on the initial assessment.

What to Ask Before You Book an EPC Assessor

Before booking any EPC assessor in Kent, ask these questions:

Do you check building control records before the assessment?
Will you access all areas of my property to obtain evidence instead of relying on software assumptions?
Will you take the time to listen to my understanding of my property?
Will you show me a copy of the result and obtain my approval before lodging onto the EPC register?
Do you record the presence of a smart thermostat?
Will you be available after the assessment to answer questions?
How do you record heating controls under RdSAP 10?
Are you insured and accredited?
