What your SAP package includes
A complete SAP assessment typically includes:
- Full SAP 10 calculations
- U‑value calculations for walls, floors, roofs, and glazing
- Thermal bridging assessment
- Energy performance modelling
- CO₂ emissions analysis
- Fabric energy efficiency rating
- Heating and hot water system assessment
- Recommendations to achieve compliance
- As‑built SAP calculations (post‑construction)
- EPC (Energy Performance Certificate)
All documents are Building Regulations‑ready and accepted by Building Control.
Our process
A clear, efficient workflow designed to get your project compliant quickly:
- Review of drawings and specifications We assess insulation, glazing, heating systems, and construction details.
- Compliance strategy If the design fails, we provide targeted recommendations to achieve compliance.
- Issue of reports We produce full SAP reports for Building Control and your design team.
Fees
Typical fees start from:
- £195–£295 for extensions
- £295–£495 for conversions
- £495–£795 for new build dwellings
- £95 for EPCs (when combined with SAP)
A fixed quote is provided after reviewing your drawings.
Borough‑specific considerations
SAP requirements are national, but local authorities often scrutinise:
- Glazing ratios in conservation areas
- Thermal upgrades in older buildings
- Heating system choices in urban boroughs
- Fabric-first approaches in sustainability‑focused councils
- Carbon reduction targets in London boroughs
We tailor your SAP strategy to both national regulations and local expectations.
Common mistakes to avoid
Projects often fail SAP or face delays when:
- Glazing exceeds allowable limits without compensation
- Insulation levels are too low
- Heating systems are inefficient or poorly specified
- Thermal bridging is ignored
- Incorrect U‑values are assumed
- SAP is left until the end of the project
Planning World ensures compliance from the start, avoiding costly redesigns.
