Each job – and each property is different, but certain factors can affect all plumbing installation costs and quotes. The cost to install plumbing will be more in larger properties and for bigger jobs, but other variables that can affect plumbing pipe prices include:
Replacing a burst water pipe is a typical task for a plumber and should cost around £100 and take 2 hours.
Plumbing pipe costs are affected by how easy it is to isolate the water supply, to access the pipe and to complete the work. Emergency call out charges are typically more expensive.
Steel or copper pipes are fine, but if you choose more expensive varieties of pipe, then plumbing costs will increase.
The average cost to plumb a bathroom is £1,675 and should take around a week to complete.
The job includes removing and replacing the toilet and cistern, bath and sink and replacing them all.
Your total bathroom replacement cost will depend on the size of the bathroom and the condition of the property. Older properties may require additional pipework to be completed, which can increase the price.
Factors such as the age and condition of your property, location and access will all affect the size of your quotation. Your choice of pipework, fixtures and fittings will all influence costs, as will the choice of whether your tradesperson will remove all waste.
If you are moving the site of a bathroom, kitchen or heating system, the cost to replace plumbing will be higher.
Plumbing a house from scratch is a complicated and expensive job.
The average cost to install plumbing in a new home with 1 main bathroom and 1 en-suite:
The quote includes the labour to install new pipework throughout the property, connecting this to mains services (water, drainage and sewerage) where required.
Your choice of pipes, fixtures and fittings will have an impact on price, as will your location and the size and style of the property.
The average cost to install a central heating system in a new 2-bedroom house is around £4000, which includes replacing the boiler, all pipework and installing new radiators. The job should take between 2-3 days.
Central heating installation costs will vary according to the type of system you opt for, with gas the most popular.
The size of the property, including the number of bedrooms, and access for pipework will affect prices. So too will the type of piping.
A good rule of thumb is: the greater the number of radiators, the higher the price.
Replacing an existing central heating system will be higher than fitting one to an empty property. If you want to replace the current central heating system in your 4-bedroom home with an entirely new one, budget to spend around £10,000 to complete the work.
The costs featured above are averages based on our research. They exclude additional costs which you may be required to pay, including:
