Setting the right budget

How much should you expect to pay?

We know it's difficult to estimate how much a project will cost, that's why we've surveyed our tradesmen to give you an idea of how much you should expect to pay for specific jobs. Tradesmen all across the country have contributed to the cost guides, so the costs you see are an approximate national average.

The main costs when installing a new water tank will arise from the need to remove the old tank and then install the new one, which could mean a considerable amount of labour hours. Obviously, these are large and heavy items, so your plumber will generally need a hand with the job from a colleague when installing and removing water tanks. Installing a new tank may mean the need for new or altered plumbing, especially if the location of the tank is being changed.

Replacing cold water tanks

With the rise in use of the combination (or ‘combi’) boiler, there is less need for cold water tanks in houses in the UK nowadays. These tanks were used in the past to provide water to refill the hot water cylinder and also to provide (non-drinking) water to some taps in the house.

A new water tank would now mostly only be installed to replace an old or corroded water tank without the need to change your water heating or central heating set up. Your plumber should be able to advise the best course of action should your water tank fail and be beyond repair.

Installing hot water tanks

The chances are that if you are having a new central heating or hot water system installed then you will opt for a combination boiler rather than use a hot water tank to heat and store water. This is because the new combi boilers are more eco-friendly and more economical in their use of fuel. But if you already have a hot water tank that is beyond repair then you will need to install a new one. Your plumber will need to drain and remove your old tank before installing the new one.

This can be time-consuming, so you need to factor that into your final bill. Any changes in location or type of hot water tank will also increase the cost of the job, as this may require extra plumbing work and new pipework. When asking for a quote do ask if the scrap value of the old water tank is included in that calculation. Copper tanks and pipes can be valuable as scrap and some plumbers may give you a discount for this, whereas others will just automatically factor that into the cost. Replacement electric immersion heaters will also add to the cost of a new hot water tank installation.
