Practical Ways to Improve Your EPC Rating

Straightforward Advice from

an Experienced Domestic Energy Assessor

Many websites provide general energy-saving advice, but not every improvement has the same effect on an Energy Performance Certificate (EPC).

The suggestions below are based on the measures that commonly influence an EPC assessment. Every property is different, but these are some of the first areas worth considering.

Loft Insulation

Loft insulation is one of the easiest and most cost-effective ways to improve your home’s energy efficiency.

If your loft insulation is thin or incomplete, topping it up can often improve your EPC rating.

Checklist

✔ Check insulation depth.

✔ Repair areas where insulation has been disturbed or removed.

✔ Ensure the loft hatch is insulated where practical.

Heating System

The heating system has a significant influence on an EPC.

If your boiler is old or inefficient, replacing it with a modern condensing boiler may improve your property’s energy performance.

For the best results, your heating system should include:

✔ Condensing gas boiler

✔ Programmer or timer

✔ Room thermostat

✔ Thermostatic Radiator Valves (TRVs)

These controls help manage heating efficiently and are recognised within the EPC assessment.

Secondary Heating

If your property already has a full central heating system, additional gas or electric fires can reduce the EPC rating.

Many homeowners keep decorative or older secondary heaters without realising they may affect the assessment.

If you’re planning improvements before obtaining a new EPC, it’s worth discussing secondary heating with your assessor.

Double Glazing

Modern double glazing helps reduce heat loss and generally performs better than older windows.

Older single glazing should be replaced where practical.

If your property already has good-quality double glazing, replacing it purely to improve the EPC may provide only a limited benefit.

Low Energy Lighting

Replacing traditional bulbs with LED lighting is a simple improvement that contributes positively to an EPC assessment.

Changing all frequently used light fittings to LED lamps is an inexpensive upgrade that also reduces electricity consumption.

Hot Water

Where a hot water cylinder is present, good insulation and suitable heating controls can improve energy efficiency.

Older cylinders without insulation jackets are less efficient than modern insulated cylinders.

Wall Insulation

If your property has cavity walls, cavity wall insulation may improve both comfort and the EPC rating.

For solid wall properties, internal or external wall insulation may be suitable, although these improvements are usually more expensive.

Floors

Some suspended timber floors can be insulated to reduce heat loss.

While not appropriate for every property, floor insulation can contribute towards improved energy efficiency.

Renewable Technologies

Solar photovoltaic (PV) panels and other renewable technologies can improve an EPC rating where suitable for the property.

However, these are generally larger investments and should be considered alongside more cost-effective measures first.

Before Spending Money

Not every improvement provides the same benefit.

In many cases, simple changes such as improving loft insulation, upgrading heating controls or replacing an older boiler may have a greater impact than more expensive alterations.

If you’re unsure where to start, a Domestic Energy Assessor can explain which improvements are likely to be most worthwhile for your particular property.
