We have an ancient conventional boiler (with big tank type of thing), we are thinking of replacing the boiler for a combi one. No idea about the prices, but they seem really expensive. Also trying to make a comparison on google proves an impossible task as it brings all sorts of things and prices. How much did you pay for your combi Boiler + Installation? Which boiler brands and companies did you use (if you don't mind me asking)?
I have been told Big Companies like British Gas overcharge. But at the same time, which small companies can you trust and give you peace of mind? Nobody likes to end up with cowboys companies while trying to avoid being overcharged by the big sharks.
