1st Gas Reviews
O’Hora, “Polite and friendly engineers”
First class service. New boiler fitted with the minimum of fuss, very clean workers with old boiler and packing taken away. Polite and friendly engineers and very good value for money. Would highly recommend.
Peter, “a really good and caring business”
People make the difference in business. The care shown in the service I have had is consistent and wonderful. Such a hard thing to find in the UK, a really good and caring business.
