About us - APNT Services

APNT Services
Go to content
Previously known as Air Pressure and Noise Testing Ltd. we have been offering an independent testing service for over 15 years in the North East of England.

APNT Services is now a division of SDL Management Services Ltd (established in the 1980's) providing both consultancy and test services to a wide range of industries.

As APNT we pride ourselves in offering a personal and professional service to large and small construction firms, house builders and self builders alike.

Our technicians are approved by our governing body;
'The Elmhurst Airtightness Scheme' (EAS) and abide by their code of practice.

In case of a complaint about our service the Directors of SDL Management Services will investigate and hopefully resolve the problem. When that is not possible it will be passed to Elmhurst Energy for resolution.
