Repair or replace?
Most boilers are worth repairing. If yours is beyond economic repair, we will say so plainly and explain why.
When it is time for a new one, Southwark Heating has fixed-price boiler installation you can book online.
Keep it running
Most breakdowns we see could have been caught early. An annual boiler service keeps your boiler safe and your manufacturer warranty valid.
