Energy Performance Certificates (EPCs) remain a critical requirement for homeowners, landlords, letting agents, and property investors across the UK. With the introduction of updated EPC conventions and modelling changes over the last year, many properties are seeing noticeable differences in their EPC scores—even when no physical improvements have been made.

If you are planning to sell, let, refinance, or improve your property, understanding how these new conventions affect your EPC rating is essential.

In this guide, we explain how changes to RdSAP conventions now influence points for windows, floors, heating systems, hot water, and electric appliances.

Why EPC Conventions Change

EPC assessments in England and Wales use a methodology called Reduced Data Standard Assessment Procedure (RdSAP).

Conventions are periodically updated to ensure assessors record properties more accurately and consistently. These updates often change how features are interpreted in the software, which can alter the final EPC score.

Recent updates have particularly impacted:

• Window assessment rules
• Solid floor assumptions
• Electric showers and hot water usage
• Heat pump modelling
• Electric underfloor heating
• Heating fuel comparisons

These adjustments can either increase or decrease your EPC score depending on the property setup.

1. Windows – Updated Assumptions Can Change EPC Points

Windows play a significant role in heat loss calculations.

Under newer conventions, assessors must be more precise when identifying glazing types.

Key changes

• If evidence of double glazing cannot be confirmed, the software may default to single glazing assumptions.
• Older double glazing may no longer automatically receive modern performance values.
• Window age and installation evidence matter more than before.

EPC Impact

This can affect several SAP points because glazing influences:

• Heat loss
• Energy demand
• Heating costs

For landlords and property owners, this means older double glazing may not score as well as previously assumed.

2. Solid Floors – More Conservative Heat Loss Calculations

Many UK homes—especially Victorian terraces and older properties common across Liverpool, Southport and West Lancashire—have solid ground floors.

Recent conventions tightened assumptions regarding:

• Floor insulation
• Floor construction
• Unknown insulation levels

EPC Impact

If insulation beneath a solid floor cannot be verified, the software may assume no insulation present, which increases heat loss.

This can reduce the EPC rating slightly, especially in ground floor flats or older houses.

3. Electric Showers and Hot Water Demand

Electric showers have become more common in modern refurbishments and rental properties.

However, EPC modelling often penalises electric hot water systems because electricity has a higher carbon factor and higher assumed cost than gas.

Key EPC Effects

Electric showers:

• Increase electricity demand
• Increase hot water energy consumption
• Can reduce the overall EPC rating

In contrast, gas heated hot water systems tend to score more favourably.

This is why some properties with electric-only systems struggle to reach EPC band C.

4. Gas Heating vs Electric Heating

One of the biggest influences on EPC scores is fuel type.

Traditionally, EPC models favour mains gas heating systems because they are cheaper per kWh than electricity.

Typical EPC Impacts

Gas boilers often score well because:

• Lower fuel costs
• Efficient condensing boiler assumptions
• Lower running cost modelling

Electric heating systems can sometimes reduce EPC scores due to:

• Higher electricity cost assumptions
• Lack of heat storage
• Higher carbon factors

However, the picture is changing as the government pushes toward electric heat pumps and low-carbon heating.

5. Heat Pumps – Better EPC Scores Than Older Electric Systems

Air source heat pumps are increasingly common due to:

• Government incentives
• The Boiler Upgrade Scheme
• Net zero targets

Unlike traditional electric heating, heat pumps can significantly improve EPC ratings because they operate with high efficiency.

Why Heat Pumps Score Well

Heat pumps typically deliver 300–400% efficiency, meaning they produce far more heat energy than electricity consumed.

This can lead to:

• Lower energy demand
• Improved EPC ratings
• Better environmental scores

For landlords aiming for future EPC C targets, heat pumps may become a viable upgrade.

6. Electric Underfloor Heating – Often Scores Poorly

Underfloor heating powered by electricity is popular in:

• Bathrooms
• Kitchens
• Renovated flats

However, from an EPC perspective it is usually considered direct electric resistance heating, which is less efficient than gas systems.

EPC Implications

Electric underfloor heating may:

• Increase electricity consumption
• Reduce EPC points
• Be treated as secondary heating

Unless paired with a heat pump system, electric underfloor heating rarely improves EPC scores.

What This Means for Homeowners and Landlords

Because of these convention changes, many property owners are surprised when:

• Their new EPC rating differs from an older certificate
• Improvements do not increase the score as expected
• Electric heating systems reduce the rating

This is why having an experienced Domestic Energy Assessor is essential.

A qualified assessor will ensure:

• Features are recorded correctly
• Evidence is used where possible
• The most accurate EPC rating is produced.

If you’re a homeowner or landlord in Southport, Liverpool, West Lancashire or across Merseyside, improving your EPC rating doesn’t have to mean expensive renovations.

Under the latest RdSAP 10 conventions, there are simple, cost-effective upgrades that can add valuable SAP points and potentially move your property from an E to a D — or even into a C rating.

Here are the smartest low-cost wins

1⃣ Loft Insulation to 270mm

Cost: £300–£600
Typical SAP Gain: +5 to +12 points

Many properties locally still have only 100mm insulation. Topping up to 270mm is one of the cheapest ways to boost your rating.

2⃣ Upgrade to 100% LED Lighting

Cost: £50–£150
SAP Gain: +1 to +3 points

Small change — but sometimes just enough to cross into the next band.

3⃣ Improve Heating Controls

Cost: £150–£600
SAP Gain: +3 to +6 points

Adding a room thermostat, programmer, or full set of TRVs can significantly improve efficiency scoring.

4⃣ Cavity Wall Insulation

Cost: £800–£1,500
SAP Gain: +5 to +10 points

Under RdSAP 10, evidence matters — so certification is important.

5⃣ Replace an Old Non-Condensing Boiler

Cost: £2,000–£3,500
SAP Gain: +8 to +15 points

Often the upgrade that shifts a property into a solid Band C.

Why RdSAP 10 Matters

Accreditation bodies such as Elmhurst Energy now require:

• Accurate laser measurements
• Photo evidence
• Reduced assumptions
• More detailed heating control recording

If improvements aren’t visible or documented, they may not be counted.

Need Just a Few Points?

EPC bands are close together:

• Band C = 69–80
• Band D = 55–68
• Band E = 39–54

Sometimes you only need 2–4 SAP points to move up a band.

Thinking of Selling or Letting?

A targeted £1,000–£2,000 improvement plan can often:

Avoid landlord compliance issues
Improve rental appeal
Increase property value
Reduce energy bills

If you’re based in Southport, Liverpool, Ormskirk, Skelmersdale or surrounding areas, message us for advice before spending money on upgrades.

A pre-improvement EPC review can show you exactly how many SAP points you need — and the cheapest way to get them.

As of 15 June 2025, domestic Energy Performance Certificate (EPC) assessments in England, Wales, Scotland, and Northern Ireland will undergo a major transformation with the rollout of RdSAP 10 software. Spearheaded by the Department for Energy Security and Net Zero (DESNZ), this update aims to enhance accuracy, reflect modern building practices, and drive the UK toward its net-zero targets. For Domestic Energy Assessors (DEAs), the changes mean updated data-collection protocols, refined calculation methodologies, and new features for renewable technologies—and they’ll also lead to longer on-site visits and, consequently, higher EPC fees. In this article, we’ll explore what’s new in RdSAP 10, how it affects your EPC ratings, and why you should expect price increases for EPCs and energy performance assessments, particularly in light of the EPC Changes June 2025. (Energy Trust, Bluewire Hub Ltd)

1. Why RdSAP 10 Matters

The Reduced Data Standard Assessment Procedure (RdSAP) underpins EPCs for existing dwellings, providing the basis for energy-efficiency ratings that influence property valuations, rental regulations, and government incentives. The version in use since 2019 (RdSAP 9.94) has been due for a comprehensive overhaul to align with the UK’s evolving building stock and environmental goals. RdSAP 10 represents this first major leap forward, incorporating lessons from the Climate Change Committee’s net-zero roadmap and Government consultations on the Home Energy Model. DEAs will see more precise assessments of heat loss, renewable technologies, and carbon emissions—critical metrics as EPCs become increasingly central to policy instruments such as the Minimum Energy Efficiency Standards (MEES) and forthcoming mortgage-linked incentives. (GOV.UK, Elmhurst Energy)

2. Release Timeline and Preparation

• Specification Published: September 2023 (BRE)
• Training & CPD Rollout: From May 2025, all Accredited Bodies will integrate RdSAP 10 modules into their CPD sessions, ensuring assessors are up to speed on new protocols (Assessor Hub, Elmhurst Energy).
• Official Go-Live: 15 June 2025, when all accredited EPC software must migrate to RdSAP 10 (Energy Trust, Bluewire Hub Ltd).

Accreditation schemes (e.g., Elmhurst, Stroma, ECMK) are hosting webinars and issuing guidance documents. DEAs should begin reviewing the RdSAP 10 specification now, undertake relevant training, and upgrade data-capture equipment (e.g., tape measures, thermal imaging devices) in anticipation of increased measurement requirements. (Assessor Hub, EPC Training)

3. Key Changes in Data Collection

3.1 Comprehensive Window Measurements

Under RdSAP 10, every window in the dwelling must be measured and logged in full. This replaces the previous “typical window area” assumption and improves the precision of heat loss calculations. Expect site-time increases of 20–30 minutes per property due to:

• Manual measurement of frame dimensions (height, width) for each window (EPC Training, Energy Trust).
• Detailed recording of glazing types (single, double, triple), frame materials (uPVC, timber, aluminium), and presence of thermal breaks (EPC Training, Elmhurst Energy).

3.2 Enhanced Insulation Profiling

Insulation inputs now support finer gradations:

3.3 Room-In-Roof Differentiation

Two separate “Room in Roof” types must now be identified: simplified or detailed. Detailed entries necessitate measurements of gable walls, common partitions, and roof slopes. This granularity aims to capture the thermal performance of loft conversions and attic bedrooms more accurately. (Elmhurst Energy, Assessor Hub)

3.4 Air-Tightness and Ventilation Options

RdSAP 10 introduces a broader array of ventilation types—mechanical extract, MVHR, trickle vents, and air-tightness test results where available. Where testers can supply an air-permeability test report, DEAs can input actual leakage figures, significantly improving the EPC’s reliability. (buildcomply.co.uk, Elmhurst Energy)

4. Methodology and Calculation Enhancements

4.1 Updated Thermal Properties

Thermal conductivity (U-values) for walls, roofs, and floors have been recalibrated to reflect modern insulation materials. This brings the RdSAP model in line with current British Standards and tested material performance, reducing discrepancies between predicted and actual energy use. (EPC Training, Elmhurst Energy)

4.2 Renewable Technology Integration

RdSAP 10 formally recognizes small-scale renewables, including:

• Battery Storage: Allows assessors to model on-site solar storage, adjusting import/export dynamics.
• PV Diverters: Models the benefit of diverting excess PV generation to electric hot water systems.
• Other Micro-Generation: Small hydro and combined heat-and-power (CHP) units can now be entered.
  This leads to more accurate estimated energy savings and carbon scores, crucial for homeowners investing in renewables. (Elmhurst Energy, AES Sustainability Consultants)

4.3 Carbon Emissions Focus

With stricter carbon targets, RdSAP 10 calculates “CO₂ per m² per year” rather than just site energy use. This shift means properties with low-carbon heating (e.g., heat pumps) may see a proportionally greater uplift in their environmental rating, even if kWh consumption remains similar. (Elmhurst Energy, AES Sustainability Consultants)

5. Impact on EPC Ratings

By improving data fidelity and expanding technology inputs, RdSAP 10 is expected to produce:

• Higher accuracy: Reduced margin of error between modelled and actual bills.
• Potential rating shifts: Well-insulated homes with renewables may gain up to 5 rating points, while poorly insulated properties without ventilation control could lose points.
• Carbon score differentiation: Homes with low-carbon heat sources will perform better on the Environmental Impact scale than on Energy Efficiency alone.

DEAs should prepare clients for possible rating changes when RdSAP 10 assessments replace older EPCs—even without physical upgrades, ratings may change simply due to new calculation rules. (Energy Trust, Elmhurst Energy)

6. Increased Assessment Time and Cost Implications

The richer dataset and longer on-site processes mean that typical assessment times will rise by an estimated 25–40%. With average RdSAP 9.94 visits taking 45–60 minutes, assessors should budget up to 90 minutes under RdSAP 10. Consequences include:

1. Reduced daily throughput: From 8–10 to 5–6 surveys per day.
2. Higher operational costs: Increased travel time, data-entry labour, and training expenses.
3. Fee adjustments: Most DEAs and accreditation bodies are reviewing pricing. Typical EPC fees may rise by 15–30% to cover the extra time and QA requirements.

Homeowners and landlords should expect higher quotes for EPCs and energy performance assessments post-June 2025. DEAs are advised to update fee schedules in advance and communicate the reasons—namely, enhanced accuracy and regulatory compliance. (EPC Training, Assessor Hub)

7. Preparing for RdSAP 10: Practical Steps for DEAs

1. Attend Accredited Training: Secure CPD slots on RdSAP 10 modules immediately.
2. Upgrade Equipment: Invest in precise tape measures, laser distance meters, and thermal imaging cameras.
3. Revise Data Templates: Customize your data-capture forms to include new fields (windows, ventilation, renewables).
4. Software Testing: Participate in pilot tests with your software provider to ensure a seamless June switchover.
5. Client Communication: Draft new service proposals explaining the benefits of RdSAP 10 accuracy and the rationale for fee increases.
6. Join Industry Forums: Engage in BRE and accreditation scheme webinars to stay updated on FAQs and errata. (Assessor Hub, AES Sustainability Consultants)

8. Frequently Asked Questions (FAQs)

Q1: Will my existing EPC remain valid after June 2025?

Yes—existing certificates remain valid for 10 years, but for new listings and government schemes, an RdSAP 10 EPC will be required for assessments carried out after 15 June 2025 (Bluewire Hub Ltd, GOV.UK).

Q2: How much more will EPCs cost?

While exact figures vary by region, most assessors anticipate a 15–30% fee increase to reflect longer on-site times and data processing (EPC Training, Assessor Hub).

Q3: Are there any exemptions?

Exemptions remain the same (listed buildings, temporary structures, houses of worship), but DEAs should confirm with their accreditation scheme whether certain data-collection steps can be waived when valid building records exist (GOV.UK, Elmhurst Energy).

10. Finally

The June 2025 rollout of RdSAP 10 represents a watershed moment for EPC professionals and homeowners alike. By demanding finer data-capture, integrating renewables, and re-focusing on carbon metrics, the new methodology promises more accurate, actionable certificates—albeit at the price of longer visits and higher fees. DEAs who prepare now—through training, equipment upgrades, and software testing—will gain a competitive edge, offering clients the most reliable energy-efficiency evaluations on the market. And by adopting SEO best practices, you’ll ensure that property owners and landlords find your updated services precisely when they need them most.

Embrace the change and position yourself as an RdSAP 10 expert—your clients, and your bottom line, will thank you.

Upgrading to a new boiler and its effect on a boiler EPC rating is a question on many homeowners’ minds as they look to enhance their property’s energy performance. The boiler EPC rating is essential for determining energy efficiency. Energy Performance Certificates (EPCs) have become increasingly important not only for compliance and regulatory purposes but also for reducing ongoing energy costs and carbon footprint. In this article, we’ll explore whether installing a new boiler can genuinely boost your boiler EPC rating, and delve into related factors, costs, and benefits. We’ll also cover practical steps you can take to maximize your home’s energy efficiency beyond just replacing the boiler. Understanding your boiler EPC rating is crucial for making informed decisions.

What Is an EPC Rating?

An Energy Performance Certificate (EPC) measures the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). EPC ratings take into account several elements, including:

• Insulation levels (loft, wall, and floor)
• Heating system efficiency (boilers, controls, and radiators)
• Hot water systems
• Lighting and thermal performance

The EPC rating is crucial when selling or renting a property in the UK, as it provides prospective buyers or tenants with an estimate of energy costs and environmental impact. A higher EPC rating signifies lower energy consumption and carbon emissions, which translates to cost savings and greater property value.

What Factors Affect EPC Ratings?

While a new boiler can influence your home’s EPC, it’s one part of a broader picture. Key factors include:

1. Building Insulation
   • Loft and cavity wall insulation are often quick wins.

5. Lighting
   • LED lighting contributes to lower energy consumption.

A higher boiler EPC rating signifies lower energy consumption and carbon emissions, which translates to cost savings and greater property value. It’s important to regularly check your boiler EPC rating to ensure your property is performing at its best.

An EPC assessor will evaluate all of these elements. Focusing solely on the boiler without addressing other inefficiencies may limit the improvement in your EPC rating.

The Role of Boilers in EPC Assessment

Boilers play a significant role in EPC calculations. They are evaluated based on:

• Boiler efficiency (e.g., A-rated boilers vs. older models)
• Age and technology (condensing vs. non-condensing)
• Heating controls (presence of thermostatic radiator valves and programmers)

Older, non-condensing boilers typically have an efficiency of around 60–70%, whereas modern condensing boilers can achieve upwards of 90% efficiency. This improvement can directly influence the energy requirement calculations that determine your EPC band.

How a New Boiler Can Improve Your EPC Rating

1. Increased Boiler Efficiency

Installing a new condensing boiler with an ErP (Energy-related Products) A-rating can significantly lower the energy required to heat your home. This improvement typically leads to:

• Reduced annual energy usage
• Lower CO₂ emissions
• Direct uplift in EPC score

2. Advanced Heating Controls

Many new boiler installations include upgraded controls, such as:

• Smart thermostats
• Weather compensation
• Zoned heating

Enhanced controls allow for precise temperature management, reducing waste and supporting a higher EPC rating.

Ultimately, a higher boiler EPC rating can significantly enhance your home’s marketability.

3. Improved Hot Water Efficiency

Modern boilers often feature better hot water standby performance and faster recovery rates, influencing the hot water assessment component of the EPC.

Types of Boilers and EPC Implications

When considering a new boiler, you’ll encounter several options:

Understanding the relationship between your heating system and the boiler EPC rating is essential for making informed energy decisions.

1. Combi Boilers
