Frequently asked questions
How much does a typical boiler repair cost?吹
The cost of a boiler repair depends on the specific fault and the price of replacement parts. For example, replacing a simple sensor is much cheaper than fitting a new PCB or heat exchanger. We provide a clear breakdown of costs after our initial diagnosis so you can make an informed decision before work begins.
How long will it take to get my heating back on?吹
Most common repairs, such as replacing a fan or a pump, can be completed within two to four hours if parts are in stock. If we need to order a specific component from the manufacturer, it may take an additional 24 hours. We aim to complete all repairs on the first visit whenever possible.
Are your engineers Gas Safe registered?吹
Yes. It is a legal requirement in the UK for anyone working on gas appliances to be on the Gas Safe Register. All our engineers carry ID cards proving their registration, ensuring that your repair is conducted safely and according to current building regulations.
What is the difference between residential and commercial repairs?吹
Commercial boilers are often larger, higher output systems found in offices or factories. They require engineers with specific commercial gas qualifications (COCN1). Residential boilers are smaller units designed for homes. We have qualified specialists available for both domestic and commercial environments.
Should I repair my boiler or replace it?吹
If your boiler is over 15 years old, frequently breaking down, or the repair cost is more than half the price of a new unit, we will likely recommend a Gas Boiler Installation instead. Newer models are significantly more efficient and come with long manufacturer warranties.
