hi Loz i get my boiler serviced every year which i find very reassuring and value for money, i have only really used them once to replace a door seal on my fridge and once to replace the pump on my washer all within the five years i've been a customer. the sales pitch from the engineer who replaced the pump made it sound like a no brainer but when you look at it in black and white it dose appear a little unnecessary,thanks so much for your comments and the link regards karen
