"Knew I needed a new boiler. It was very easy to buy online, they get an installer for you then arrange the work. It was a really quick turnaround which was really appreciated. The installer was fantastic did the job didn’t leave a mess and agreed to book in a service for next year so I don’t forget to book it in. Would highly recommend "

Mrs L Eberhard
"Ordered my boiler on line through the Worcester Bosh Web site on Saturday. The boiler was fitted on the following Thursday. Step by step guide was easy to follow. The fixed installation price was £300 to £400 cheaper than other company's for the same boiler. That with 12 years warranty. Great service, thank you. "

JUSTIN WHEELER
"Booked new replacement boiler installation on Tuesday evening and installation completed by Thursday midday. Everything done in two days and all as expected. Really easy process, prompt response and work completed as indicated. Really good service and cost effective too. "

"Our new boiler was fitted within a day and has proved to be efficient and economical. The wireless thermostat control is a big plus given our previous WB boiler was over 20 years old but still working perfectly just the same. "
David Ferguson
" Very simple process, answer a few questions, take a few pictures for the installer, pick a boiler, pick an installation date and away you go. "
Keith
"The customer service staff that I have dealt with have always been extremely helpful, and knowledgeable about the product. "
Paul Lawrenson
"The product does what it says on the tin. What was particularly pleasing was we had to use the warranty as the boiler developed a fault and the experience was exceptional. The typical warranty experience is for the warranty supplier to tie you up in knots and avoid any responsibility. Bosch is entirely different - out within 72 hours, fixed in a couple of hours and a tidy written and verbal report stipulating what was wrong and also making a couple of small but useful suggestions about the installation. "
Paul Daly
"Works perfectly, we replaced our tank and boiler with a combi, and have not looked back. Instant hot water every time and savings on energy overall by installing. "
