As experienced plumbers, CAFCO can recommend the best boiler to suit your property. We'll offer you truly independent advice as we are not tied to particular manufacturers. Every boiler installation includes our first class customer service and flexible approach.
As a letting agent or private landlord, you are legally required to make sure that each of you rental properties have a current gas safety certificate. Our team is fully qualified and will find a convenient time to carry out the required checks.
Gas boilers need servicing every year to ensure they are working efficiently and safely. Regular checks often extend the lifespan of the boiler too. The CAFCO team will remind you when your boiler service is due. We'll arrange a convenient appointment time - and stick to it! We are proud of the customer service and reliability we offer. You'll have the peace of mind of a fixed price to service your boiler. Should any extra parts be needed, we'll always let you know what is involved - and at what price - before going ahead. Often, we'll have the parts with us, keeping your boiler servicing as convenient as possible.
The new boilers are much more efficient and therefore cost effective compared with older models. CAFCO works with all types of boilers and the leading manufacturers such as Worcester, Vaillant, Ideal and Baxi. If you are thinking of upgrading, ask us for a free, no-obligation quote. You'll be pleasantly surprised!
