Absolutely fantastic job. Matt was very tidy and polite, and came across as very professional. I’d originally booked the power flush as British Gas recommended one as they couldn’t fix my central heating issues. Not only did Matt do the powerflush, he also found the problem (which was the heat exchanger) and managed to clear it out! I now have working central heating, which took British Gas 5 visits and 6 engineers to fail! Revive is worth every penny!
