B4B installed a new gas central heating system for me to replace a storage heater system. They were very professional, from providing a competative quote through to signing off the job. They were accommodating with me splitting the job into 2 parts while we were waiting for the new National Grid gas connection. I found them to be responsive, punctual, polite and friendly throughout. The work was done quickly and it was a very tidy job. I would certainly use them again. Thanks.
