Burst pipe at 8pm and they were out within the hour. Professional, tidy and fair on price. Saved us from a flooded kitchen.

New Vaillant boiler fitted in a day. Clear quote, no surprises, and they walked us through everything at handover.

I manage 12 properties and CAF handles every gas certificate. Reminders before they expire and the cert in my inbox the same day. Faultless.
