Plumbing and Heating Guarantee

We provide our heating and plumbing services to customers throughout West London including, Ealing, Hanwell, Harrow, Kingston, Wembley and Middlesex.

Omniscient Building Services (OBS) has been trading since 1993 and we pride ourselves on the fact that most of our new business comes from customers referring us onto friends and family.

We feel that part of our success is the guarantee that we offer. While each individual service has specific guarantees (for example, two year guaranteed workmanship on the installation of boilers and central heating systems), we have an overall guarantee that covers everything we do.
