10 Questions To Ask Before Hiring A Boiler Technician In London
1. Are You Gas Safe Registered?
This is the most important question. Any boiler technician in London must be Gas Safe registered to work on gas appliances legally. Always ask for their registration number and verify it on the Gas Safe Register.
At Maintracts, all our engineers are fully Gas Safe registered, ensuring complete compliance and home safety.
2. What Qualifications And Training Do You Have?
Look for a qualified boiler technician in London with up-to-date certifications, manufacturer-specific training, and experience with various boiler types, especially if you own a combi or commercial system.
We proudly employ certified boiler professionals trained to work on all major makes and models, including combi, system, and conventional boilers.
3. How Long Have You Been Working In The Industry?
Experience matters, especially when dealing with older systems or more complex installations. Ask how long they’ve been offering London boiler services and whether they’ve worked on similar systems to yours.
We’ve been providing reliable boiler engineer services in London since 1974, building our reputation on consistent quality and trusted expertise.
4. What Services Do You Offer?
You’ll want a technician who can handle everything from annual boiler servicing to emergency boiler repairs and complete installations.
Maintracts covers all boiler needs under one roof—from combi boiler servicing in London to system upgrades, breakdown diagnostics, and landlord certificates.
5. Do You Provide Transparent Pricing And Written Estimates?
Cost transparency builds trust. Ask for a precise quote and find out whether they charge by the hour or by the job.
We always offer upfront, itemised quotes with no hidden costs. Whether you need a boiler repair expert or a boiler installation professional, you’ll know exactly what you’re paying for before we begin.
6. Can You Provide References Or Reviews From Past Customers?
Customer reviews are a goldmine of insight into reliability and service quality. Look for testimonials, Google reviews, or even check platforms like Checkatrade.
We’re proud to showcase our 5-star feedback across London, demonstrating our standing as an experienced boiler technician in London residents' trust.

Boiler problems rarely strike at a convenient time. A sound technician should offer fast response times, especially in the winter months.
Our team is available 24/7 for emergency boiler repairs, as we understand the importance of heating and hot water in maintaining your everyday comfort.
8. What Boiler Brands Do You Specialise In?
Not all engineers are comfortable with every brand. If you have a Vaillant, Worcester Bosch, Ideal, or another specific model, ask if they have experience with it.
We’re certified to work with most major boiler brands, and our engineers have hands-on experience with a wide range of systems, ensuring expert support every time.
9. Do You Include A Warranty Or Guarantee On Your Work?
A good boiler contractor in London should stand behind their work. Ask about workmanship guarantees and whether any parts they use are covered by warranty.
At Maintracts, we offer robust guarantees on all work performed and supply parts only from reputable manufacturers.

FAQs
1. What’s the difference between a boiler technician and a heating engineer?
While both work on heating systems, a boiler technician is typically focused on boiler-specific tasks, such as servicing, installation, and fault-finding. A heating engineer may work more broadly across central heating systems.
2. How often should I service my boiler in London?
We recommend annual boiler servicing to maintain efficiency, prevent costly breakdowns, and ensure safe operation, especially during colder months.
3. How do I know if my technician is Gas Safe registered?
Ask for their Gas Safe ID and check it on the official Gas Safe Register website. It’s your right as a homeowner to ensure your technician is legally authorised to work on gas appliances.
4. Should I repair or replace my boiler?
If your boiler is more than 10–15 years old, frequently breaks down, or is inefficient, it may be time to replace it. A boiler repair expert can help you assess the condition and advise on the most cost-effective solution.
5. What are the signs of a boiler fault I shouldn’t ignore?
Common red flags include low pressure, strange noises, inconsistent heating, or a yellow flame. Don’t ignore these—call a professional heating technician promptly for a safety inspection.
6. Do you offer support for both homes and businesses?
Yes, we offer residential boiler care and commercial boiler services across London. Whether it’s a home combi boiler or a large-scale system, we’ve got you covered.
