5 signs your boiler might need replacing

Your radiators take longer to heat up

If your radiators take too long to heat up or your water doesn’t come through as hot as it used to, it might mean your radiators need bleeding – or your boiler is on the way out.

Your boiler is old and costing more to run

Heating systems can lose their efficiency and cost more to run as they age. So look for the ErP energy label to see how efficient yours should be – they go from dark green (A-rated and most efficient) down to red (G-rated and least efficient). All new condensing boilers in the UK must now be A rated.

Your boiler is leaking water

Boiler puddles mean internal parts could be faulty or are beginning to fall apart – and it could be time for a new boiler. It’s a good idea to take action right away, if you can.

Your boiler is making unusual noises

Beyond your boiler’s normal firing-up sound or gentle purr, other noises could mean trouble – from broken valves, heat pump issues, to general wear and tear.

Your boiler smells

This is serious. It might be that a leak is causing the boiler to not burn properly, which puts you at risk from carbon monoxide. If you suspect a leak, call the National Gas Emergency Service on 0800 111 999 straight away.

Questions on new boilers

Yes, of course. Please call the CORGI HomeHeat Sales Team on 0800 085 6398 Monday to Friday between 8am and 7.30pm – or Saturday between 8am and 4pm. They’ll be more than happy to help.

Rest assured, your boiler will only be fitted by a local and trusted Gas Safe engineer.

CORGI HomeHeat offers 3 top-quality boiler brands: Intergas (a Dutch manufacturer), Ideal (a British manufacturer), and Worcester Bosch (an award-winning German manufacturer).

It depends on the size of the job. If it’s a straightforward swap, CORGI HomeHeat can get your old one out – and your new one in – within a day. But if you’re looking to convert your system from a conventional boiler system to a combi system, this can take 2 to 3 days.

You just need to make sure your boiler and flue are accessible. The Gas Safe engineer may also need to get to your radiators.

There could be additional costs if you need extra work doing beyond a straightforward boiler replacement. This could be something like upgrading your gas supply if your current heating system is old and your gas supply pipe isn’t within current regulations. Or you want to move your boiler to a different location and you need extra pipework installed.

1 According to the Energy Saving Trust (April 2022), a detached household moving from a G-rated boiler to a new A-rated condensing boiler with a programmer, room thermostat and thermostatic radiator controls (TRVs) could save up to £840 a year. Savings will vary depending on the size and thermal performance of your home. Here are their calculations.

2 An independent study has shown that installing and correctly using a tadoº smart thermostat can reduce your energy use from heating by up to 31%. The study found that the tadoº device can reduce heating energy requirements by 14-26% through controlling the heat source (e.g. boiler or heat pump). You could also save another 7% by turning down the heating based on the weather forecast, depending on the window sizes. If the window surfaces are relatively large, the energy saving will increase.
