Independent Domestic Energy Performance Certificates for landlords, letting agents, homeowners and housing providers across Plymouth, Devon, Cornwall and the wider South West.
Reliable · Trusted · Fast · Covering Plymouth, Devon & Cornwall
Oak Energy EPC is an independent EPC business based in Plymouth, run by qualified Domestic Energy Assessor Sandra Radovanovic. We provide Domestic Energy Performance Certificates for landlords, letting agents, homeowners and housing providers across Devon, Cornwall and the wider South West.
Our approach comes down to one simple line: Your Property. Our Focus.
Oak Energy EPC was set up with a simple idea: getting an EPC shouldn't be a hassle. Too often, property owners are left waiting weeks for an appointment, chasing a certificate or trying to make sense of a report nobody has explained to them. We wanted to offer something better: a local assessor who's easy to reach, turns up when promised and takes the time to explain what the rating actually means.
Being independent makes a real difference to the service you get:
No call centres, no being passed between departments.
From Victorian terraces in Plymouth to rural cottages in Cornwall, we know the housing stock of the South West.
Our job is to give you an accurate rating and clear information, so you can decide what's right for your property.
We can fit around your tenants, your agents and your diary, and scale up for larger portfolios and contracts.
I’ve worked in property for over 16 years, moving into net zero and energy efficiency in 2019. Since then, I’ve gained experience across ECO3, ECO4 and the Green Homes Grant, qualified as a Domestic Energy Assessor, and developed practical retrofit expertise.
I’m passionate about helping homeowners, landlords and tenants create warmer, healthier homes.
I enjoy helping people understand their homes better. An EPC is more than a certificate for a sale or a let. It's a snapshot of how a home uses energy, and with the right advice it can be the first step towards a warmer home that costs less to run.
Sandra Radovanovic, Owner
Every EPC we produce is carried out to the government's standards and lodged on the national EPC register, so you can be confident your certificate is valid and accurate.
EPCs can feel like just another box to tick. We'd like yours to be the easiest part of your sale, let or project. Here's what you can expect every time you book with Oak Energy:
Appointments are confirmed in advance and kept. If anything changes, you'll hear from us straight away.
From booking to certificate, you'll always know what's happening and when.
No jargon. We'll talk you through your rating and recommendations in plain English.
We'll tell you which improvements are likely to make a difference, and which probably aren't worth the money.
Our assessments are non-invasive, and we treat every home, and every tenant, with care.
We work with a wide range of clients across the South West, from individual homeowners to large housing providers.
Improving the energy efficiency of our homes is one of the most practical ways to cut energy bills, keep people warmer and reduce carbon emissions. With the rules for rented homes tightening towards 2030, good-quality EPCs and clear advice matter more than ever.
That's why we care about what happens after the certificate is issued. Whether it's modelling the most cost-effective route to an EPC C or pointing you towards available funding, we're here to help you take sensible next steps.
Growing up among Surrey’s legendary oaks gave me a lifelong connection to these remarkable trees. Years later, I named my son after the oak, so Oak Energy felt like the natural choice for my business. To me, an oak represents more than sustainability: it supports an entire ecosystem. I believe warmer, more energy-efficient homes can help people live healthier, more comfortable lives.
“Sandra came to complete an EPC on our Edwardian home, as our previous assessment had been carried out in 2009 and was now outdated.
She took the time to explain the changes and what she needed to consider when assessing the energy rating of an older property.
We had been having difficulty securing a Local Authority grant because of the EPC requirements and other grant criteria. Sandra’s knowledge, care and understanding of the process helped us push the application through and gave us the confidence to proceed.
As a result of her assessment and guidance, we were able to successfully apply for the Local Authority grant. We’re extremely grateful for her help.”

“Since Sandra came into our office to introduce herself and explain her services, arranging EPCs has been an absolute pleasure.
Nothing is ever too much trouble — even last-minute requests are never a problem. Sandra is always incredibly efficient, reliable and professional, and she is such a lovely person to deal with.
It’s great to have someone we can rely on, and we wouldn’t hesitate to recommend Sandra and Oak Energy to anyone needing an EPC.”

Lettings Manager, Hindhead Property
“As landlords, achieving an EPC C was really important to us.
Sandra assessed our renovation project when it was originally rated EPC D. We followed her recommendations and were really pleased to achieve an EPC C.
Sandra is knowledgeable, friendly and professional, and we found her advice really helpful throughout.
We will definitely call on her again and would highly recommend her services.”
