When you are running a hotel and an oil boiler breaks down you know your guests are not going to have any heating in their rooms that night. Fortunately one call to Ignite and an engineer turned up in the hour. He was even carrying the required spare part. A great service I would highly recommend, which saved our bacon!

Paul Williams

Fantastic service from Chris @ Ignite Facility Service, Initial contact to after service care.
Chris was polite, curtious, we have 2 large dogs , he seemed at ease with them both.
He replaced our fan and gave the boiler a full service, bled all our radiators.
Will definitely be using him again to service our boiler etc..
I have recommended him to friends and colleagues.
