Brendan came round promptly and immediately diagnosed the faults in my sabre he25 condensing boiler and pipes, he took readings with digital equipment and explained the printed out results, he found a gas leak and sealed it straight away, the water leak was also stopped, i would recommend him as a fast-working and gas engineer, also found his pricing very competitive and was helpful all the way, I have now a fully functioning boiler and would recommend Brendan for any future work!
