Visiting our premises
We welcome visitors to our laboratories, but are not able to see anyone without a prior appointment. Please contact us for an appointment and directions on how to find us.
Please note that as our postcode covers a large rural area, entering it into a sat-nav will direct you to an address approximately 1km north of our site. Please contact us for more precise directions.
Our laboratories are situated reasonably close to the A55 Chester to Holyhead road but are approached along narrow country lanes. These lanes are NOT suitable for vehicles over 7.5 tons, high-sided vehicles or articulated vehicles. We would insist on the vehicle having a tail lift when delivering or collecting large items.
Please note that whilst our postal address is ‘St. Asaph’, Tremeirchion is based some distance away from the town.
