Complete SAP & EPC Services: From Planning to Completion
Sub-headline: Professional SAP calculations, Predicted Energy Assessments, and Energy Performance Certificates (EPCs) for Part L compliance. Your single solution for London Plan Energy Statements and Building Control approval.
Understanding SAP Calculations: The Heart of UK Building Compliance
A Standard Assessment Procedure (SAP) calculation is the government-approved methodology for assessing the energy performance of new dwellings. It is not just a formality; it is a mandatory requirement for Building Regulations approval under Part L (Conservation of Fuel and Power).
Whether you are building a single house or a large residential development, a certified SAP assessment provides the evidence that your project meets the UK's energy efficiency standards, resulting in the Energy Performance Certificate (EPC) for the property.
The Complete Energy Assessment Journey: From Planning to Completion
1. Predicted Energy Assessment (PEA) - The Planning Stage Document
What it is: A report based on the Design Stage SAP calculation that shows the expected energy efficiency of the new dwelling(s).
When it's needed: Required for marketing new-build homes before construction is complete, typically at the planning stage.
Why it matters: Provides potential buyers with an indication of the home's future running costs and environmental impact. Essential for developers selling properties off-plan.
2. Design Stage SAP - The Blueprint for Compliance
Purpose: Assesses the proposed design against Part L standards before construction begins.
Key outputs:
Draft EPC (showing potential energy rating)
Data for London Plan Energy Statements
Basis for Building Control initial approval
3. As-Built SAP - The Final Verification
Purpose: Final assessment using actual construction details and products installed.
Final EPC (the official energy rating certificate)
Building Control completion sign-off
Mandatory document for new home warranties
4. Energy Performance Certificates (EPCs) - The Final Result
Draft EPC: Generated from the Design Stage SAP, used for planning and marketing
Final EPC: Legal requirement for all new homes, generated from the As-Built SAP
Validity: EPCs are valid for 10 years from issue date
The Critical Role of SAP in the Broader Compliance Landscape
Connecting Energy Performance to Planning & Building Control
A SAP calculation is often the central piece of evidence in a web of compliance requirements.
1. SAP & Part L Building Regulations
This is the primary purpose of the SAP calculation.
For New Dwellings (Part L1A): The SAP calculation determines your Dwelling Emission Rate (DER) and Dwelling Fabric Energy Efficiency (DFEE), which must be better than or equal to the Target Emission Rate (TER) and Target Fabric Energy Efficiency (TFEE).
For Dwellings Created by Conversion (Part L1B): The calculation demonstrates that the upgraded dwelling meets the required standards for existing buildings.
2. SAP & The London Plan Energy Statement
The London Plan requires a dedicated Energy Strategy report at the planning application stage. Your SAP calculation is the quantitative foundation of this report.
Proof of Performance: The Energy Statement uses the predicted energy performance from the Design Stage SAP to demonstrate how the development will exceed baseline Part L requirements, a key demand of the London Plan.
Low-Energy Trajectory: It shows planners a clear path to achieving the required carbon reductions, often linking to future connection to district heating or renewable energy targets.
3. SAP & Building Control
No Building Control body in England or Wales will issue a completion certificate for a new dwelling without a final As-Built SAP calculation and the resulting EPC. It is the definitive proof that the constructed building complies with Part L.
We clarify which regulation your project falls under based on your planning application and commencement dates.
We design strategies that are optimized for the new rules, focusing on a genuine 'Fabric First' approach to avoid over-reliance on expensive renewables.
We provide clear, comparative advice if your project spans the regulatory transition.

FAQ Section
Q: What's the difference between a Predicted Energy Assessment and an EPC?
A: A PEA is used for marketing off-plan homes (before construction), while an EPC is the final legal certificate required upon completion.
Q: When do I need a Draft EPC vs Final EPC?
A: A Draft EPC is generated from the Design Stage SAP for planning and marketing. The Final EPC comes from the As-Built SAP and is legally required for completion.
Q: My project received planning permission under the old regulations. Which standards apply?
A: This depends on your "commencement date." If you started on-site before June 2023, you likely fall under the old rules. We can provide definitive advice for your specific situation.
Q: Why is the London Plan asking for my SAP data at the planning stage?
A: Planners need to verify that your energy strategy is credible and that the development will meet its carbon reduction targets. The Design Stage SAP is the evidence.
Q: How long does it take to get a Final EPC after completion?
A: We typically process and register Final EPCs within 24-48 hours of receiving all required information.

The New Era of Building Comfort: Part O Overheating Regulations
As of June 2022, Part O of the Building Regulations mandates a formal assessment of overheating risk in all new residential developments. The goal is clear: to protect occupant health, well-being, and productivity by ensuring homes remain comfortable during the summer months without excessive reliance on energy-intensive mechanical cooling.
Our service provides fully compliant Part O Overheating Calculations using the industry-standard CIBSE TM59 methodology, giving designers, developers, and planning authorities the confidence that your building is fit for the future.
Part O, SAP Calculations & London Plan Energy Statements
An Integrated Approach to Sustainable Design
Overheating risk cannot be viewed in isolation. It is deeply connected to your project's energy performance and overall sustainability strategy, particularly under the London Plan.
1. Part O & SAP Calculations: The Energy Efficiency Paradox
Modern, highly insulated and airtight buildings (designed to excel in SAP calculations for winter energy efficiency) can be more susceptible to trapping unwanted solar heat gain in the summer.
A design that achieves an excellent SAP score by maximizing solar gains for winter heating might fail the Part O assessment due to excessive summer overheating.
Our Integrated Solution: We model your design to find the optimal balance. We ensure your building meets Part O requirements without unnecessarily compromising your Part L compliance or SAP score. This prevents costly redesigns and ensures a truly comfortable, low-energy home year-round.
2. Part O & The London Plan Energy Statement
The London Plan places a strong emphasis on climate resilience, making overheating a central issue for planning approval.
Mandatory and Enhanced Requirements: The London Plan not only requires compliance with Part O but often demands a more robust demonstration of mitigation. Our reports are tailored to satisfy both the basic regulation and the more stringent expectations of London planning authorities.
Reducing Reliance on Air Conditioning: A key goal of both Part O and the London Plan is to limit the use of mechanical cooling, which increases energy consumption and contributes to the urban heat island effect. Our strategies focus on passive measures (e.g., solar shading, cross-ventilation, thermal mass), which we highlight in your Energy Statement to showcase a holistic, low-carbon design approach.
The London Focus: Councils with Stringent Overheating Rules
While all London developments must adhere to the London Plan, several boroughs are known for their particularly rigorous scrutiny of overheating risk due to dense urban form, limited green space, and historical issues. Our expertise is critical for projects in boroughs such as:
Tower Hamlets
Southwark
Newham
Greenwich
Hackney
Islington
These councils often require explicit and detailed evidence within the Energy Statement that demonstrates a proactive, design-led approach to mitigating overheating risk, going beyond the bare minimum of Part O. We structure our reports to pre-empt and fully address these local authority concerns.

FAQ Section
Q: What is the difference between the simplified and dynamic method in Part O?
A: The simplified method uses fixed criteria for glazing areas and opening areas. The dynamic method (using CIBSE TM59) is a more sophisticated simulation that provides greater design flexibility and is often necessary for complex buildings or those in high-risk urban locations.
Q: Is a Part O assessment mandatory for my project?
A: Yes, for all new residential dwellings (houses, flats, and institutional residences like care homes) as of June 2022. Some conversions may also require it.
Q: Why is my London borough asking about overheating at the planning stage?
A: Because the London Plan requires developments to be climate-resilient. They need assurance before granting permission that the design will not lead to unhealthy living conditions or high carbon emissions from cooling.
Q: Can you help if my initial design fails the Part O assessment?
A: Absolutely. We specialize in providing practical, design-focused solutions to mitigate risk, such as optimizing window sizes, recommending shading systems, and enhancing natural ventilation strategies.

Why Water Efficiency Matters in Modern Construction
Water efficiency is no longer an optional sustainability feature—it's a mandatory requirement under Part G of the Building Regulations. For any new dwelling or conversion, demonstrating that potential water use does not exceed 125 litres per person per day is crucial for Building Control sign-off.
In London, the London Plan pushes this standard further, requiring a tighter limit of 110 litres per person per day for most major developments. Our expert Part G calculations ensure your project not only meets these legal requirements but is also primed for a seamless planning and building control process.
Part G, SAP Calculations & Energy Statements
A Holistic Approach to Compliance
While often viewed in isolation, Part G water efficiency is intrinsically linked to your project's overall energy and sustainability strategy. Here’s how our integrated service ensures complete compliance:
1. Part G & SAP Calculations: Two Sides of the Same Coin
Your SAP (Standard Assessment Procedure) calculation, required for Energy Performance Certificates (EPCs) and Part L compliance, directly incorporates the outcomes of your Part G assessment.
Hot Water Demand: The water efficiency of your fittings directly influences the amount of hot water needed. A lower hot water demand, achieved through efficient taps and showers, reduces the energy required for water heating. This improves your SAP score, helping you meet the Target Fabric Energy Efficiency (TFEE) and Dwelling Emission Rate (DER) more easily.
A Cohesive Strategy: By aligning your Part G and SAP strategies from the outset, we can optimize both water and energy performance, creating a more sustainable and compliant building without unnecessary cost.
2. Part G & The London Plan Energy Statement
The London Plan Energy Strategy requires a holistic demonstration of your development's sustainability. Water efficiency is a cornerstone of this strategy.
Mandatory Requirement: The London Plan explicitly mandates compliance with the tighter 110 l/p/day water efficiency target. Our Part G calculation is the evidence required to prove this.
Circular Economy & Sustainable Infrastructure: Reducing water consumption lessens the strain on municipal water supply and treatment networks. In your Energy Statement, this demonstrates a commitment to the circular economy and reduces the development's overall environmental footprint—a key consideration for Planning Officers.
A Streamlined Submission: We integrate the results of your Part G calculation directly into your comprehensive Energy Statement Report, creating a unified and powerful submission for London planning authorities that covers both energy and water sustainability.
Our Part G Water Efficiency Service
We provide an end-to-end service to guide you from design to compliance.
Pre-Design Advice: We recommend cost-effective, high-performance fixtures to meet your target.
Detailed Part G Calculation: A building-control-ready report proving compliance with 125 l/p/day (UK) or 110 l/p/day (London).
Integrated Reporting: Seamless integration of your water data into SAP calculations and London Plan Energy Statements.
