Your EPC doesn’t just record your property’s current energy rating, it also lists specific, prioritised recommendations for improving it. Here’s what typically moves the needle, and why it’s worth acting on.
What the recommendations usually cover
Every EPC report ends with a tailored list of improvement measures, roughly ordered by impact and cost effectiveness. The most common recommendations include:
- Loft and cavity wall insulation, often the single biggest, cheapest improvement available for older properties.
- Draught proofing around doors, windows and floorboards.
- Upgrading to LED lighting throughout the property.
- Improving heating controls, thermostatic radiator valves, programmable timers, zoned heating.
- Double or triple glazing where the property still has single glazing.
- Boiler upgrades or renewables such as solar panels, for a bigger jump in rating.
Why the rating band actually matters
Beyond lower energy bills, your EPC band has real practical consequences. Rental properties in England and Wales must currently meet a minimum EPC band E to be let, Scotland’s threshold is band D, and these minimum standards have tightened over time and may tighten further. A property sitting just below a threshold can become unlettable until it’s improved, so knowing your rating well ahead of a letting or sale gives you time to act, rather than scrambling at the last minute.
A better rating can also be a genuine selling point: buyers increasingly factor estimated running costs into their decision, and a strong EPC band is evidence, not just a claim.
Do improvements require a new EPC?
Your existing certificate stays valid for its full 10 year term regardless of any work you carry out. But if you’ve made meaningful upgrades, it’s worth commissioning a new assessment to have the improved rating officially recorded, the old certificate won’t reflect the change on its own.
Where to start
Your own EPC report is the best starting point, it’s already been calculated for your specific property, not a generic guide. Focus on the highest impact, lowest cost items first (insulation and draught proofing are usually top of the list), then reassess.
