EPCs · Retrofit Assessment · Retrofit Coordination
Retrohaus surveys homes and commercial buildings across Coventry, Warwickshire and the wider Midlands. Every EPC, retrofit assessment and floor plan is measured on site, photographed and lodged properly, so the result stands up when it matters.
Accredited and accountable
Our assessors are accredited through Elmhurst Energy, ECMK and Quidos, the government-approved schemes that train, insure and audit energy assessors. Retrohaus is also registered with TrustMark, the Government Endorsed Quality Scheme.
How to check our accreditation
Before you book
An EPC lasts 10 years and belongs to the property, not the owner. Enter a postcode and we will take you to the government register, where you can see the current rating and the date it runs out.
If it has expired, or the home has been extended, re-glazed or re-heated since, a new assessment is worth having. That is where we come in.
Opens the official register in a new tab. It is free, and it shows the rating and the expiry date.
What we do
Homeowners, landlords, agents, housing providers and local authorities use Retrohaus for the same reason: the survey is done once, done carefully, and the paperwork is right.
Our core service
Needed whenever a home is sold, let or newly built, and valid for 10 years. We assess existing homes of every age and type, from Victorian terraces to modern flats, lodge the certificate on the government register and send you the digital copy.
The A to G bands and the points behind each one. A higher score means lower running costs.
Certificates for single lets, HMOs and portfolios, with a clear view of what band C by 2030 means for each property.

Read moreWhy evidence matters
Since 1 October 2026 every energy assessor in England and Wales has had to meet new minimum evidence requirements. The test is simple: an auditor must be able to reproduce the certificate from the assessor's photographs, measurements and notes alone.
That suits the way we already work, and it protects you. Where something cannot be seen or proven, the calculation has to fall back on assumptions for a home of that age, and the rating usually suffers. Good evidence is how insulation hidden behind plaster or under loft boards gets counted.
How to prepare for your assessmentA floor plan for every level, in metres to two decimal places, with each window sized and its direction noted.
Every elevation, the depth of the loft insulation, the boiler's data plate, the heating controls and the meters.
Certificates and guarantees for work nobody can see, such as cavity wall insulation or replacement glazing.
Lodged through a government-approved scheme that checks our work. Your certificate carries our assessor's name.
How it works
Call, email or send the form. Give us the property type, its size and the postcode, and we reply within 24 hours with a clear price.
Most visits are booked within 24 to 48 hours. Let us know if a tenant or an agent will be giving access.
A typical home takes between 30 minutes and 2 hours. We need to see every room, the loft, the boiler and the meters. Nothing is drilled or disturbed.
Your EPC goes onto the government register and the digital copy comes to you, with a plain-English note on what would improve the rating.
For landlords
In January 2026 the government confirmed that privately rented homes in England and Wales must reach the equivalent of EPC band C by 1 October 2030, with spending capped at £10,000 per property. A home that earns a band C certificate before 1 October 2029 is treated as compliant until that certificate expires.
If your EPC was issued before June 2025 it used the older method. A fresh assessment shows where the property stands now and what it would take to reach C at the lowest cost.
Letting below E without a registered exemption can bring fines of up to £5,000 per property.
A band C certificate obtained before this date counts as compliant until it expires.
One date for new and existing tenancies, with penalties of up to £30,000 per property.

Questions we hear every week

All EPC questionsYou need one whenever a property is sold, let or newly built. It has to be ordered before the property is marketed, and buyers or tenants are entitled to see it. If a valid certificate already exists, you can keep using it.
10 years. You can check the expiry date for any address in England, Wales or Northern Ireland on the GOV.UK register. You can also renew sooner if the home has been improved and you want the rating to show it.
Between 30 minutes and 2 hours for most homes, depending on size and layout. We need access to every room, the loft, the boiler and the meters. The survey is non-invasive: nothing is drilled or lifted.
Visits are usually booked within 24 to 48 hours. If you have a completion date or a tenancy start to meet, tell us when you enquire and we will work to it.
There is no fixed national price. It depends on the size and type of the property. Send us the postcode and the number of bedrooms and we will give you a clear price before you book, with no hidden fees. Our guide to EPC cost explains what moves the price up or down.
Every certificate names the assessor and their accreditation scheme, and anyone can look an assessor up on the government's find an assessor service. TrustMark registration can be checked on the TrustMark website. Our accreditations page shows you how to do both.
