Boiler Installation in London
Proper boiler installation is the difference between fifteen years of quiet, efficient heating and a unit that breaks twice a year. Ilir has been installing combi, system and regular boilers across London since 2004. Every install is done by Ilir himself — never a subcontractor, never a trainee. He’ll survey your existing system honestly, recommend the right size boiler for your home (not the biggest one he can sell), remove the old unit safely and install the new one to current building regulations. If it’s a Worcester Bosch boiler and Ilir is accredited, you’ll get up to a 12-year manufacturer warranty — and Ilir’s own workmanship guarantee on top. No commission deals, no upsells you don’t need, no apprentices learning on your kitchen.
