Our British Gas annual Homecare policy (covering central heating plus plumbing and drains) is up for renewal and even after haggling on the phone (which I do every year) the lowest increase I've got them to is another £6 a month. Meanwhile I've been offered (via our water supplier) plumbing and drains cover with HomeServe for just £6 for the first year, which is tempting. I want to stick with BG for central heating cover but do I cancel the plumbing and drains with them and take out a separate policy with Home Serve?
What would you do?
