One of the guys phoned a few hours after me posting this job, and through the fairly in depth conversation I immediately felt comfortable with hiring them.
Their price wasn't THE lowest, but it's not always about just price.
We agreed a date (just over a week away) for them to do the work, and the evening before, they confirmed that they would be around as agreed.
Paul arrived promptly looking casually professional in a monogramed polo top. He assessed the job and explained a few things. Basically he got on with the job with no issues whatsoever; I asked a few questions now and then, and every one was answered satisfactorily.
After a short lunch break Jake arrived and they continued to completion.
Paul explained and clarified everything that had been done, and I was very happy with the small amount of disruption that the work had inevitably caused. I had previously asked for a receipt detailing exactly what had been done (in case the boiler manufacturer had any later concerns). The next day I received a detailed invoice and the price was exactly what they had quoted; not a penny more.
In summary, these guys are a credit to their trade and I could not be happier with the work they did. I would absolutely recommend them.
We have had no issues with the work and the whole system seems to be working perfectly.
Well done guys - and thank you.
Regards Mark and Jean in Chesham
