How it started

Tony Hernandez

Tony Hernandez

Owner, Heating & Plumbing Expert

AHP /Advanced, Heating and Plumbing Ltd was founded by Tony Hernandez. As a family run business, we do everything possible to ensure an efficient and cost effective process for all our customers.

Working as a team, we know just how important it is to provide a warm home for your family, how vital it is to restore water and heating services when in need.

Tony has always shown his passion in the plumbing and heating service industry since a young age. In 1987, Tony finished school, he then began his journey by starting as an apprentice, working on the sky scrapers being built in London Docklands.

Work was incredibly short term, leading Tony to find more secure work as a trainee engineer for Pottertons, Baxi and Vokera Boiler manufacturers. He learnt all aspects of fixing boilers inside and out.

After numerous companies lost their contracts, he began to sub-contract for emergency heating companies in central London. He soon realised that most heating companies didn’t possess anywhere near the experience, expertise or customer service knowledge required, so Tony started his own company in 1998 and since has learnt to become the expert trouble-shooter through different repair work , which at this present date now amounts to over 25 years of experience.

When Tony isn’t fixing boiler and plumbing problems, he enjoys the great outdoors , trekking, sports and hill walking with his wife, Sharon (who also works in the business) and their three kids.

“My team and I get a lot of satisfaction helping customers fixing their heating and plumbing problems, Especially where others have failed.. I pride myself on good customer service , infallible trouble-shooting and job completion – every time!!” – Tony Hernandez

Only the Highest Quality Work

Happy Customers

Tony and Taylor were very efficient and friendly. We went out and left them to get on with the work of installing our new boiler when we came back the job was done: very much to my satisfaction. I have no hesitation in recommending them.

Peter Chadwick, London

We had leak on the filling loop on our boiler on a Saturday afternoon. Tony responded to our call really quickly and Facetimed me so he could see what the problem was. Turned out to be a simple fix which Tony guided me to. Great, proactive and helpful service.

Nicholas Pimlott, Watford

Tony came promptly to fix a water leak from internal piping. He diagnosed the fault swiftly and efficiently and reached it for repair with minimal damage to ceiling and plasterwork. The problem was sorted out very effectively and at a really competitive price. Tony knows what he is doing and provides quick, efficient and professional service. He’s very highly recommended by us!

Martyn Atkins, Hertfordshire

Great customer service from Tony. Called him on Easter Sunday 3 years after installation and he guided me patiently through a problem.

Guy Katz, Middlesex

The service provided by Tony and his colleague was excellent. They manage to remove the old, tank base boiler and fitted a brand new one within a day. I would definitely recommend them
