If the current heating system is especially old it may require new parts, such as a mechanical flush, which can cost an extra £500, approximately.If you want to change your style of boiler, out-of-date materials and equipment will need to be removed as a result.This could include a hot water storage cylinder and cold water storage tank, among other things. If fresh plumbing is required, this will add to the overall cost, too. All of these factors could easily land you with a £1,500 bill.Since most companies offer free, no-obligation quotes, it makes sense to get around three valuations before committing yourself to an installer. You’ll then have the opportunity to take on board the advice provided by each engineer – and compare prices.While combi boilers are usually simple to fit, installation costs will go up or down based on the size of the unit and whether or not any radiators need to be replaced.The length of the flue (which safely vents gases) will need to be taken into account, too.Labour costs will be greater if you need a water tank and/or hot water cylinder to be removed.
