An Energy Performance Certificate (EPC) rates the energy efficiency of your rental property on a scale from A (most efficient) to G (least efficient). Since April 2020, rental properties in England and Wales must have a minimum rating of E, and proposed regulations may raise this to C in coming years.
This guide covers how much an EPC costs, when you need one, and whether investing in energy efficiency improvements is worth the money for landlords looking to future-proof their portfolio.
How Much Does an EPC Cost?
An EPC is one of the cheaper compliance costs for landlords. The assessment must be carried out by an accredited Domestic Energy Assessor (DEA), and prices are fairly consistent across the UK:
| Property Type | Average Cost |
|---|---|
| 1-bedroom flat | £60–£75 |
| 2-bedroom flat or house | £65–£85 |
| 3-bedroom house | £70–£95 |
| 4-bedroom house | £80–£110 |
| Large or unusual property | £100–£120 |
The variation is smaller than other compliance costs because the assessment process is relatively standardised. The assessor records the property's dimensions, construction type, heating system, insulation, windows, and lighting, then inputs the data into approved software to generate the rating.
Unlike gas safety certificates and EICRs, you do not need to shop around extensively for an EPC. The assessment is standardised and different assessors should produce the same (or very similar) result for the same property.
What Is Included in the EPC?
The EPC includes two key elements:
- Energy efficiency rating: A score from 1 to 100, mapped to a letter grade from A to G. Band A (92–100) is the most efficient; Band G (1–20) is the least.
- Recommendations report: A list of suggested improvements ranked by cost-effectiveness, with estimated savings on energy bills and approximate installation costs.
- Environmental impact rating: A separate CO2 emissions rating, also on an A to G scale.
- Estimated energy costs: Projected annual costs for heating, hot water, and lighting based on standardised assumptions.
The recommendations report is particularly valuable for landlords because it tells you exactly which improvements will have the biggest impact on your rating, and at what cost.
When Do You Need a New EPC?
An EPC is valid for 10 years from the date of issue. However, you need one in specific circumstances:
- Before marketing: You must have a valid EPC before you advertise a property for rent. The rating must be included in all property listings.
- Before a new tenancy: A copy of the EPC must be provided to the tenant before the tenancy agreement is signed.
- After major energy improvements: If you have carried out significant works (new boiler, insulation, windows), getting a new EPC will reflect the improved rating and make the property more attractive to tenants.
- If the current EPC has expired: Even if the property has not changed, you need a new assessment once the 10-year validity period ends.
Even if your current EPC is still valid, consider getting a new one after making improvements. A better rating makes your property more competitive and may allow you to command higher rent from energy-conscious tenants.
Cost of Common Energy Efficiency Improvements
The EPC recommendations report will suggest specific improvements for your property. Here are the most common ones, with typical costs and the impact they have on your rating:
| Improvement | Typical Cost | Potential Rating Improvement | Annual Tenant Saving |
|---|---|---|---|
| Loft insulation (270mm) | £300–£600 | 5–10 points | £100–£200 |
| Cavity wall insulation | £500–£1,500 | 5–15 points | £100–£250 |
| New condensing boiler | £2,000–£4,000 | 10–20 points | £150–£350 |
| Double glazing (full house) | £3,000–£7,000 | 5–10 points | £75–£150 |
| LED lighting throughout | £50–£150 | 1–3 points | £20–£40 |
| Hot water cylinder insulation | £15–£30 | 1–2 points | £20–£40 |
| Draught-proofing | £100–£300 | 1–3 points | £20–£50 |
| Solar PV panels | £4,000–£8,000 | 10–20 points | £200–£400 |
Cost-Benefit Analysis: Are Improvements Worth It?
Whether energy improvements make financial sense depends on your property's current rating, the cost of the work, and the potential return. Here is a practical framework:
Properties Rated E or Below
If your property is rated E, F, or G, improvements are not optional — they are a legal requirement. Since April 2020, you cannot let a property with a rating below E unless you have a valid exemption. The minimum energy efficiency standard (MEES) means you must invest regardless of the return on investment.
Properties Rated D
Band D properties are legally compliant today, but proposed regulations may require a minimum C rating in future. Investing in improvements now — particularly low-cost measures like loft insulation (£300–£600) and LED lighting (£50–£150) — is a sensible strategy to stay ahead of regulatory changes and reduce void periods.
Properties Rated C or Above
Further improvements are unlikely to be cost-effective purely for compliance, but they can make your property more attractive. Energy-efficient properties tend to let faster and experience lower tenant turnover. Higher-rated properties can also command a small rent premium in competitive markets.
Best value improvements: Loft insulation and LED lighting offer the best return on investment for most properties. Both are inexpensive, quick to install, and can improve your rating by several points at minimal cost.
How to Find an EPC Assessor
EPC assessors must be accredited through a government-approved scheme. You can find one by:
- Searching the EPC Register at EPC.OpenCommunities.org
- Asking your letting agent (many include EPCs as part of their managed service)
- Checking local directories or comparison sites like Checkatrade
- Asking other landlords for recommendations
The assessment itself typically takes 30–60 minutes for a standard property. The assessor will need access to all rooms, the loft (if accessible), and the boiler. The certificate is usually issued within 24–48 hours.
Tracking EPC Expiry with Latch
An EPC lasts 10 years, which makes it easy to forget about — until you need to re-let the property and realise the certificate has expired. Latch stores each property's EPC details and sends reminders before expiry, ensuring you always have a valid certificate ready when you need it.
Latch also helps you track the costs of energy efficiency improvements as property expenses, which is important for your tax records. Certain improvements qualify as allowable expenses, and having accurate records ensures you claim everything you are entitled to.
