Old property with rooms spread out over some distance, previously serviced by two boilers. Problems with gas supply to remote boiler was driver for switching to a single boiler solution. CVPH were very patient and helpful over a two year period when planning the upgrade. Provided a sensible quote for a job which had several unknowns due to the nature of the property. Calin and Ray provided a thoroughly professional service throughout the upgrade, cheerfully providing solutions to each issue thrown up by the property as the install progressed. The install is very neat and tidy, with no corners cut (I checked!) and I would thoroughly recommend their services.
