Used Dan at Quantum twice for our flat and I'm very happy with his service. Prompt, reliable, courteous and conscientious. Great communication from start to finish and excellent use of modern tech for payment, emailed receipts and invoices.
A really great company. I needed a plumber on a Friday and John clearly put in a lot of effort to find one. Within 3 hours, both Clayton and Charlie attended and worked on the boiler. Tricia has been great with responding to emails. Highly recommend Quantum.
I had called Quantum to renew our 50-year-old consumer unit and install an electric pottery kiln. Superb from start to finish. Dan fully explained the job and gave a summary on completion. Nice to have a team of skilled electricians who offer a trustworthy service.
