Great professional service from start to end. My HIU pressure was very low and I needed to ensure the heating could work in the lead up to the colder months. I contacted Add Detail via the chat service on their website, managed to secure an appointment for the next day. Justin, the engineer who attended and serviced the HIU unit was happy to provide explanation to all my questions. He tidy up after the work and did not leave a mess (esp when compared to other engineers that have attended in the past). All the paperwork (invoice + report) was emailed through before he drove off. It was a very smooth experience, no chasing required and payment was made after attendance. It was also cheaper when compared to one the management company recommended.
