Due to government legislation in normal circumstances when you plan to install a new boiler or replace an existing one, you will need a condensing boiler to meet the standards for energy efficiency. Similar standards applying to oil-fired hot-water central-heating boilers.
What is a condensing boiler?
Condensing boilers are more efficient than ordinary boilers and so produce less carbon dioxide, while still meeting heating needs. They reduce the amount of heat that escapes up the flue, compared with ordinary boilers. Condensing boilers convert 86 per cent or more of the fuel they use into useful heat and many carry the Energy Efficiency Recommended logo. Older types of ordinary boilers may convert as little as 60 per cent of the fuel to useful heat.
Do I have to change my boiler now?
No. The new standards apply only if you decide to change your existing hot-water central-heating boiler or if you decide to change to one of these boilers from another form of heating system.
Are condensing boilers more expensive than normal boilers?
They may be more expensive to install, but you will:
- Save money on your heating bills
- Help to tackle climate change
Do I have to have a condensing boiler?
No. You should have a condensing boiler fitted if it is reasonable to do so, but the law recognises that non-condensing boilers are acceptable if it would be too difficult to install a condensing boiler in your home. Your installer will tell you whether your circumstances are too difficult.
If I need a new boiler, what should I do?
Choose a qualified central-heating installer who understands the new standards and can advise you on the type of boiler you should have fitted.
Choosing an installer
For gas-fired boilers, the installers you employ must be Gas Safe registered as a safety requirement, and they should also be capable of installing condensing boilers.
For oil-fired boilers, you can employ an OFTEC-registered installer, or some other reputable installer who is capable of installing condensing boilers. If you employ an installer who is not registered with OFTEC, you will need to contact us before the installation work starts by submitting a Building Notice.
How do I know if my installer is capable of fitting condensing boilers?
In all cases, check that your installer has recent qualifications in energy efficiency. If your installer is Gas Safe or OFTEC registered, those organisations can confirm this;
Gas Safe: www.gassaferegister.co.uk
If they are not registered, you will need to ask your installer if they hold a certificate in “Energy Efficiency for Domestic Heating” or an equivalent qualification.
If your installer advises you that it would be unreasonable to install a condensing boiler in your home, they should give you a declaration form for you to keep.
If your boiler is installed by a registered installer, you will get a building regulations compliance certificate from the registered organisation after the work has been completed (to show that the work meets building regulations standards).
If your boiler is being installed by someone who is not registered you will need to contact us before the installation work starts by submitting a Building Notice. We will then check that the work has been carried out to the necessary standards, providing that it does we will issue you with a completion certificate.
You should keep these certificates as you may need them when you sell your home.
