‘Getting it done in late winter or early spring means you’re ahead of the rush’, continues Michael. ‘You’re probably using the boiler heavily, so that’s a good point to check for wear and tear. And you don’t panic because the house is getting cold.’

Do you need your boiler serviced?
The best way is to have your boiler serviced regularly Make sure your boiler is running efficiently – But is it a legal requirement?
‘There’s no law in the UK that says homeowners have to have their boiler serviced once a year, but it’s highly recommended and, in many cases, most boiler manufacturers say you need to have it serviced annually to keep your warranty,’ explains Gordon Chalk. ‘Without annual maintenance from a trained specialist, some problems cannot be covered, leaving you with huge costs. It’s not just about legislation and guarantees; It is also about safety and efficiency. This is something we always stress to our customers, as a broken boiler can cause serious problems.’
That said, as Michael Zohouri points out, there are few instances where boiler servicing becomes a legal requirement. ‘By law, if you are a landlord, an annual gas safety certificate is required.’

Having your boiler serviced annually should be at the top of your home maintenance list – especially if you don’t want to. Replace the boiler Anytime soon.
‘In my experience, small problems become expensive when boilers are not regularly serviced,’ warns Michael Zohouri. Things like debris, seal or pressure problems are usually picked up during service. I have seen boilers run at low efficiency because they are clogged or not burning fuel cleanly. That means the gas bill is higher. In the worst case scenario, poor maintenance can lead to carbon monoxide hazards.’
‘A boiler that has not been serviced can become less efficient over time. Parts can get stuck, rusted or worn, making the boiler work harder and use more fuel to heat the same amount of space,’ Gordon chalks up. This directly leads to higher energy bills, which a well-insulated home or UFH system It works well.’
‘Having an annual boiler service will also ensure that you are protected against carbon monoxide poisoning so it is crucial that you book this every year ahead of time,’ adds. Ian Palmer-SmithAt Appliance Repair Specialist domestic and ordinary. ‘I also strongly advise getting a carbon monoxide detector if you don’t already have one. A faulty boiler system can leak carbon monoxide gas into your home, but without any colour, smell or taste, you need a detector to alert you to its presence to stay safe. They usually last five years before they need to be replaced.’

‘Anywhere between £80 and £120 for a standard service, depending on your area and boiler type,’ says Michael Zohoury. ‘Some companies offer service plans that spread the cost each month. Compared to the cost of a replacement boiler, it’s a small investment.’
Ian Palmer-Smith adds that ‘During a boiler service, engineers will identify any potential problems before they develop into serious problems. ‘Catching problems early will help extend the lifespan of your device.
