Hello, I'm just after a bit of advice. I've recently bought a 3 bed semi in dire need of updating. Currently there is a lead mains pipe, and to the bathroom fittings. And microbore piping to the rads. Boiler is a 2018 Vailant combi. Lead needs replacing, with new bathroom plumbing. So too does the microbore and new rads throughout. What would be a cost estimate to replace the above. Its a standard size 3 bed semi, i.e. one lounge, kitchen diner, hallway, 3 beds and 1 bath. Thanks in advance!
