and I'm fine with that! We rent our house out through an agency as we are abroad for 2 years. The tenants have been in touch to say that the boiler is leaking. The engineer came out immediately (we have a british Gas Homecare Agreement), but can't fix it for another 48 hours, even though they are in the 'at risk' group with a toddler and 3 week old baby. They have told our agent they can't live there with no heating, so we have offered to rent/buy heaters to keep them cosy. Again, I'm fine with that and I would feel the same. I'm just sitting here wondering though, who would pay the electricity bill if it was much higher than usual, and if we had to pay, how would they calculate it? Just bracing ourselves for more costs. Any ideas?
