I had a problem with temperature fluctuations on my shower, and received 6 quotations from tradespeople on this site. Aquaviva's quotation was a third of the other quotations I received. Fabrizzio and Anna were a joy to work with. They were excellent communicators by email before the job. They arrived punctually. Most importantly, they did the work quickly and efficiently, to a good standard. Affordable plumbing work is incredibly rare in London, and this company is a marvel. Highly recommended.
