Hello guys. New member to the forum. I'm a gas safe registered engineer and just set up working for myself after always being employed. I'm just looking for advice from you guys in regards to quoting for jobs as I've never really had to deal with pricing large jobs. I've done a fair few small jobs and straight forward boiler swaps but I've been asked by a customer to quote for a complete install where there is no existing boiler only a cylinder and emersion. The customer wants a 30kw combi with 8 rads over three floors with all pipework included. It'll be the first complete system I've done by myself and I'm really struggling to price the job. So I was just wondering how you guys go about estimating for materials and labour and pricing accordingly. Sorry if it's a long winded post and I appreciate any advise or criticism. Thanks in advance.
