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.

We know you want fast, accurate compliance. Guaranteed.

Our Part L package is designed to take the headache out of the process. Our coordinated package bundles all the vital services: SAP calculations, air tightness testing and EPC production into a single, streamlined process. When you order our Part L package of services we guarantee to provide your EPC certificate within 24 hours of the air test taking place.

As well as the cost and time savings you gain by keeping all your compliance under the care of one expert team, you can track progress via the FES Cloud.

SAP Calculations

On average, we complete 600 - 700 SAP assessments a month, so you can rely on us to provide a friendly, expert service, as well as staying bang up to date with any regulation changes.

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.

24 Hours from test to EPC

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 residential Part L Package.

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.
