A new boiler that is serviced annually can last up to 15 years before needing to be replaced. 

First it’s important to consider the signs such as frequent leaks and constant breaking down. However, the need for a boiler replacement is best assessed by a Gas Safe Registered heating engineer. When the costs to repair a boiler are nearing the cost of a new one, usually the advice will be to fit a new boiler. 

To supply and fit a combi boiler, it will usually cost in the region of £1200 - £2000 +VAT. This will usually depend on if this is a replacement, or if the system needs changing. Boiler brand and manufacturer can also play a significant role in price too. 

Depending on the boiler type and the system requirements, it can take anywhere between 1 and 3 days. If it is a simple replacement, it’s usually around a day, but if a new system needs to be fitted this can take longer.

There are various grants available, but they do change frequently, and can be difficult to be accepted for. Most grants are domestic, and are related to increasing the energy efficiency of your home.

No, you don’t need new radiators with a new boiler if they are all working correctly, and hot all over. However, it is recommended to install a system filter with a new boiler, which helps to protect radiators from debris that can build up in the system. 

It takes years of training, qualification and experience to correctly install a new boiler. In fact, by law a new boiler can’t be installed by anyone who isn’t Gas Safe Registered. It is dangerous to attempt to do this yourself, and you should always contact a Gas Safe Registered heating engineer. 

A new boiler doesn’t necessarily increase the value of a house, but an old and faulty boiler can decrease value, as more often solicitors and buyers will ask for service reports on boilers. If new boilers are needed as a result of reports and checks, then sometimes buyers ask for price reductions.

It can vary depending on age, make and model, however a new boiler of today's standards can last up to 15 years before needing to be replaced. 

An old boiler can be dangerous if not correctly set up and serviced regularly. Leaking and corroded boilers can leak harmful carbon monoxide into your house.

A boiler should be replaced when the cost of repairing it approaches a similar cost of installing a new one. Alternatively, it is advisable to consider replacing a boiler when parts are no longer available for repairs.
