Illy completed a full bathroom renovation for me, as well as replacing radiators. He was incredibly reliable, kept in constant communication and completed the work to a great standard. I couldn't recommend him and the team more, and I am hugely grateful to him for the work completed.

My boiler stopped working completely during a winter cold snap. I contacted Ilirjan and he quickly responded with a quote and a couple of different boiler options, and then carried out the work and commissioning swiftly over the next couple of days. Ilirjan and Alex were friendly and tidy from the start. They took time and care over the work, and did a neat, professional and thorough job. The boiler and boiler flue were admittedly in a tricky location requiring the removal/reinstallation of part of a cupboard unit, but they were installed neatly with positivity and at no extra cost. Ilirjan also checked and adjusted all of the radiators as part of the job, talked me through thermostat controls and arranged all relevant warranty and safety documents. All costs were as the original quote, no extra charges. I also feel secure that I have a direct contact I would feel comfortable calling back with any questions about the system.

Really happy with our boiler replacement, Ilirjan was very professional and friendly. He was really tidy too and left the flat with no signs work had been done. He even came and had a look at other bits and bobs around the house and gave me some advice. He took his time and made me feel comfortable that it was being done properly.

Working with Illy, Ed and his team of subcontractors was extremely positive. They refurbed a bathroom over the course of about a week, and I was very pleased with the results in terms of finish and schedule. Illy is trustworthy and considerate, would absolutely recommend in the future.

I was recently let down by a plumber last minute and asked around for recommendations. I was given Illy’s number and contacted him. He responded quickly and managed to fit me in that day. He serviced my boiler on the day and also gave me a quote for replacing all the radiators in my flat. He gave me a lot of helpful advice as to which radiators to choose and has now fitted them all. Great communication, reasonable and detailed quotes and a fantastic job - they look great. I couldn’t be happier and I will almost certainly be calling on him again.

Ilirjan came promptly to help us with a leak from our old water tank which he dealt with very proficiently. In our conversation, he offered some options for improvement without any pressure. Having agreed to fit a new combi boiler at a fair price, I found him to be prompt, thorough, trustworthy and professional. Wouldn't hesitate for a moment to recommend him.

Illy has worked for me several times now: repairing the boiler, replacing and servicing the new boiler, and re -jigging water supply after removing the large cold water tank from the attic. Replacing hot water cylinder. Ive got to know Illy well and find him thoroughly reliable, friendly, and efficient. I have recommended him to several people and will always use him to service the new boiler in the future.

First class plumber, gas boiler and central heating engineer. Clearly enjoys and is very proud of his work and thereby delivered a very professional, skilful and friendly job at a fair price. Our old combi boiler needed replacement. He gave an almost immediate quote And fixed date for the work. Not pushy. Very open he attended with a colleague and carried out the work exactly to order and the system now works very well. Very neat work. He came back a few days later at my request to Carry out new work on the Old central heating pipes and radiators. Again all very precise, clear and reasonably priced. A good find. He came to us on the recommendation of neighbours who similarily found this couple of years ago
