It could be a case of the part just needing a good clean or recondition to get it back in tip-top condition – for example, an engineer may be able to fix a faulty fan by simply changing its motor. This will be much kinder on the purse strings.We wish it were plain sailing from here, but the prices of parts can fluctuate. The averages above provide a guideline of the price of different parts, but there are a lot of factors that can affect it. What can affect the cost of boiler repairs?Boiler parts are pesky little things. They can sometimes end up costing you hundreds of pounds just to get a bit of a spruce up.Furthermore, there are a number of additional factors that can either pile a few pounds onto the bill, or indeed knock them off. These factors can range from where you live, to the type and age of your boiler.Check out the different factors that can affect the price of boiler parts below:• The type of boiler you have – If you have a larger, more complex model, this will add a few more pounds onto your bill. For instance, a conventional boiler will cost substantially more than a combi boiler.• The age of your boiler – The longer you keep your boiler, the more outdated the parts will be. If your boiler is over 15 years old, it’s likely that the engineer will struggle to find the parts required, or charge extra for them.• The company that you use – Many people go for a national company to repair their boiler, usually because they are more familiar with the company. However, if you go for local companies, you can expect less of a hefty bill at the end of it.• Your home’s location – Boiler engineers charge different rates depending on your location. If you live in London, prepare for engineers to charge double compared to engineers in northern England. Typical London life, eh?• The cost of spare parts – If the part that needs repairing is crucial to the functioning of your boiler, it will cost more to fix. For example, a boiler’s circuit board will cost over twice as much to repair as its timer. Fixed price boiler repair vs time-based boiler repairWhen comparing different companies, you’ll notice that there are two types of prices – just to keep you on your toes. Companies typically offer both fixed price and time-based repairs. A fixed price repair says what it does on the tin: you pay a fixed price for a one-off boiler repair. You’ll receive a straightforward quote, which includes the total cost of replacement parts and labour.For time-based repairs, however, you pay by the amount of time it takes to repair the boiler. The longer a fault takes to fix, the more the engineer will charge you.Want to compare different prices from big brand name companies?

But is it worth it? Boiler cover: Is it worth it?In short, yes. Since over half of the money spent on your energy bills come from your boiler, it’s important to look after it as well as you can.The name is fairly self-explanatory – boiler cover is a type of insurance that covers repairs for your boiler. Certain boiler cover deals also include your annual boiler service, while some can even include boiler replacement. Depending on how much you’d like to splash out, there are a few options you can go with:• Basic boiler cover – This option covers your boiler, as well as providing the option for annual maintenance checks. If you’re lucky, the company will usually have a 24/7 call centre, so you can arrange a call-out if your boiler breaks down.• Boiler and central heating cover – This has all the benefits of basic boiler cover, with additional cover for radiators, pumps, and flue.• Boiler central heating and wiring cover – Again, this option has all the same features as basic boiler cover. It has additional options to cover your plumbing and drains, electrical wiring, or both.Check out the different prices you can expect to see for all three different types of boiler cover below.
