Construction Compliance Services

No-one wants sign-off held up by expensive and stressful compliance problems. That’s why we offer our clients simple optional packages of services, bundling together everything you need for residential or commercial compliance.

Our packages are the most cost-effective and stress-free way of getting the certification you need. But if you just want to pick and choose from our individual services, that’s fine too. You’ll get the same dedicated team of experts and the same seamless customer service. 

Take a look at the full list of how we can help.

When it comes to commercial building projects, you don’t want to be chasing certification or making expensive last-minute alterations to get sign-off.

Our commercial Part L package takes the stress away by pulling together all our key services, making sure you’ve got all the paperwork you need for EPC, air tightness testing, SBEM calculations, thermal modelling, acoustics and BREEAM.

Our expert team promises a seamless service and you can track the whole project in real time, via the FES Cloud.

SBEM Calculations

The most stress-free way of getting your Simplified Building Energy Model calculations is simply to order our commercial Part L package and all the relevant tests and certification will be included. You can even track the progress via our cloud technology.


We’re accredited for all Building Research Establishment Environmental Assessment Method categories, so if your commercial project needs to achieve a BREEAM rating, we can help.

Thermal & Daylight Modelling

Our experience in energy modelling and daylight/sunlight analysis is fully focused on helping designers to save development money and even ongoing running costs. If you need IES modelling for your project, get in touch.

Air Tightness Testing

We’re here to help you get the certification you need. If something goes wrong and your building isn’t quite compliant, we’ll stay on site, work with you and re-test, wherever possible. 

What’s more, we promise a 24 hour turnaround of your certificate, along with your EPC, when you order our residential or commercial package of services.

EPC Certification

The last thing you need is to have sales held up because you’re waiting for your Energy Performance Certificate. That’s why we promise to get you the vital paperwork within 24 hours of your air test, when you book our commercial packages.

Given that we complete 600 - 700 EPCs a month, we’re pretty confident about what we do, with in-house staff available nationwide to work on projects of all sizes.
