Hi, My elderly and sick mum has been quoted a crazy amount by BG to fix her heating... £1100! She has a 12 year old boiler and a larger than normal pump on it (so they say) a UPS25-80180, as the flat is long and thin. Heating went off a couple of weeks ago. BG guy said that pump had packed up cos of sludge, would need to do a powerflush, and take all the 13 rads off (!) at a cost of £1100 + VAT. Another engineer came and said that they would do powerflush and supply and fit new pump for £650 + VAT. Obviously this is much better as its almost half the cost of the BG one, but I just wanted to know if this was the case, as reading on here that often they diagnose power flushes when none is needed... Thanks for any help
