Every Test. Every Certificate. One Team.
Flint Energy delivers the full suite of building compliance tests required for new build and retrofit projects - including air permeability, acoustic, ventilation and water efficiency — carried out by our accredited in-house team.
Expert Compliance Testing for Developments & Buildings
Building compliance testing is a critical stage of construction.
Air permeability, acoustic performance, ventilation and water efficiency all require physical testing and certification before practical completion.
For developers and contractors, the challenge is coordination. Managing multiple testing specialists across a live construction programme creates scheduling risk and leaves gaps in accountability when results fail or arrive late.
Flint Energy removes that problem. Our accredited in-house team carries out the full suite of compliance tests, coordinating with your programme so testing happens at the right time and documentation is ready for handover.
Proven Results
Delivering measurable compliance across new build and retrofit projects.
Everything you need to reach practical completion, from one accredited team.

// Why Work With Us
Simple, Transparent Process
Getting compliance testing right does not need to be complicated. Here is how we work:
Initial assessment and programme review
SAP modelling and system assessment
On-site testing at the agreed programme stage
Certification and documentation issued
Support with building control queries. No surprises, no delays.
// How it Works
Aligned With Your Goals, Not Just Regulations
Flint Energy works best when engaged early in the programme. Early involvement means we can flag potential issues before they become failures, coordinate testing across multiple plots or phases and integrate seamlessly with your SAP assessor, M&E consultant and main contractor.
When compliance testing is managed by the same team that carried out your energy modelling and EPC work, the process is faster, the documentation is consistent and the risk of late surprises is significantly reduced.
✔ Programme-stage coordination to avoid delays
✔ On-call support through construction
✔ As-built EPCs and SAP updates where required
✔ Direct liaison with building control on your behalf

Common Questions We Are Asked
Still have questions? Take a look at the FAQ or reach out anytime. If you’re feeling ready, go ahead and apply.
-
Air permeability testing is required for all new dwellings and new commercial buildings under Part L of the Building Regulations. Testing must be carried out on completed buildings before the as-built SAP calculation and EPC can be produced. For developments of more than two units, a proportion of the plots must be tested. Flint Energy can advise on the testing strategy for your development.
-
If a building fails its air permeability test, remedial work is required to identify and seal air leakage paths before retesting. Common causes include gaps around service penetrations, poorly fitted windows and doors and incomplete sealing at junctions. Flint Energy can provide guidance on likely failure points and support retesting once remedial work is complete.
-
Yes. Part E acoustic testing is required for material changes of use as well as new build projects, including conversions of houses into flats and commercial buildings into residential use. The required performance standards vary depending on the type of conversion. Flint Energy can advise on the applicable requirements for your project.
-
Mechanical ventilation systems including MVHR, MEV and single room heat recovery ventilation require commissioning and testing under Part F. Natural ventilation systems do not require formal testing but must be specified and installed to meet the ventilation requirements. Flint Energy carries out commissioning and testing for all mechanical ventilation system types.
-
Part O applies to all new residential buildings in England, including flats, houses and student accommodation. It is particularly relevant for south-facing properties, high-glazing designs and apartments where solar gain is a risk. Both simplified and dynamic thermal modelling routes are available depending on the complexity of the project.
-
SBEM (Standard Building Energy Model) is the calculation methodology used to demonstrate Part L compliance for non-domestic buildings. It is required for new commercial, industrial and mixed-use buildings and for major refurbishments of existing non-domestic properties. Flint Energy carries out SBEM calculations for building control submission across a range of commercial building types.
-
Yes. Flint Energy carries out air permeability, acoustic, ventilation, overheating, water efficiency and energy modelling directly, using our own accredited team. We can manage all compliance testing for a development under a single contract, coordinated with your SAP and EPC work where required.
