We have just had a new boiler fitted by George. A very professional trades-person, who took great pride in his work. He worked tirelessly all day, and left the work area clean and tidy when he was finished. After a long day he then took the time to run us through the boiler, and nest thermostat instructions. So top marks for George. When I booked the installation I paid for the boiler to be moved over, however this was not required, and after a short call to Heatable they reimbursed me within 2 hours without quibble. So top marks to heatable as well. I would gladly recommend this service to anyone.
