Hi guys. A friend of mine has bought a flat and wants to buy a Worcester Greenstar 25 si combi boiler ( code: 7716130139)for his flat that was installed at another friend"s flat. He wants to buy it, i will be running the pipework and will call a Gas Safe engineer to install the boiler. The best price for the boiler i have come across is # 958.21 inclusive of 100mm telescopic standard horizontal flue kit, digital programmer DT20 and free delivery. Can i find the same boiler cheaper elsewhere? And what do you think of the above mentioned boiler? Thanks for your time.
