Rhyno Heating and Ventilation came to install a new electric boiler and hot water tank. They recommended Andrew Richardson for the electrical work needed for this job and co-ordinated their work with his. We were very happy with the work done. The only thing I would point out to anyone using this firm is that they charge 2% for Credit or Debit Card payment. I feel that they should be able to absorb the charges made from Credit Card companies, rather than putting it onto the customer. This was the reason they did not receive 10/10.
