Are You About to Spend Too Much on a New Boiler?

Some people can end up paying well over even £10,000 for work on their boiler and pipes when disreputable engineers are added.

Having a broken boiler in the middle of winter is stressful enough without having to worry that a rogue engineer is overcharging you. Here are some steps to avoid paying too much for a new boiler replacement.

Quick and easy 2025 - iHeat new boiler cost guide

1. Know What You’re Looking For

Knowing what you’re looking for in a new boiler cost can help you estimate roughly how much you should spend on your boiler replacement.

Having even a small amount of knowledge can also help you to determine if an engineer is trying to pull the wool over your eyes when it comes to what you need.

It’s worth researching beforehand which boiler is right for your home. This includes taking a look at your current boiler.

You may be looking to swap your old system out for a combi boiler, or you may just be looking to replace your current combi with a brand-new one.

You should also consider whether your boiler uses LPG or gas and the output size your household requires.

The size of the boiler often refers to the output in kilowatts (kW) as opposed to the physical dimensions of the boiler itself. Kilowatts are the measurement of energy that is output by the boiler in the form of heat.

Generally, the bigger your home and family, the larger the output you’ll need and the more expensive the boiler.

iHeat has a helpful guide on how to determine the right type and size of boiler for your home.

2. Account for Extra Costs

If you are planning to have your boiler moved, or if the job is more complex, such as removing a back boiler, you should expect to pay extra on top of the average boiler and installation cost.

Sometimes, you may require new pipes if the old ones are leaking which can also cost extra. Any optional features such as smart thermostats and wireless controls will also pose additional costs.

3. Get Multiple Quotes

As tempting as it may be to get your boiler repaired as soon as possible, calling an engineer and accepting the first quote you're given is a mistake. As you would with most things, shop around for the best deal.

According to the Energy Saving Trust, the average new boiler installation costs around £2,300, but you can expect to find a boiler installation between £1,500 and £3,500, depending on the factors you’ve already considered.

Once you have found multiple quotes, you should evaluate the trustworthiness of the engineers who have given them.

If the cheapest quote came from an installer with one star reviews for example, you know you should probably avoid them.

4. Arrange a Finance Plan that Suits You

Ensure you can pay for your boiler the way you want to. If you require a finance plan over 10 years, make sure that this is an option your installer can offer you to avoid an awkward conversation if they require an upfront payment.
