Boiler Repair Reviews

See what homeowners across Sheffield think about our boiler repair services.

"I arranged a gas boiler service for my brother-in-law as he doesn’t do computers. Chris was very understanding and did the job within the week. Would recommend and certainly have him again."
"Chris from SAS Gas Services came to service our boiler, picked up it had originally been installed incorrectly, and took ownership of the fault for us, contacting Ideal and the original plumber who did the fitting by phone to get it all resolved for us. We have used SAS since, we were so impressed."
"Sam fitted a new boiler and en-suite in my first house and a full new heating system including boiler, pipe work and radiators. Can not fault him, did a brilliant job, professional, fast, reliable, and tidy. Always on hand when needed for servicing and repairs also. Would highly recommend."
"Fantastic! Did a 10/10 job on fixing our boiler in winter. Was out to me in less than 18 hours and got us back up and running in no time. Really reasonably priced and friendly too! Would highly recommend."

Our Boiler Repair Process

We believe boiler repairs should be simple. Here's what you can expect when you choose SAS Gas.

Step 1: Contact Our Team

Call us to discuss the problem you're experiencing. We'll arrange a convenient appointment and answer any initial questions.

Step 2: Thorough Fault Diagnosis

Your engineer will carry out a detailed inspection to identify the cause of the fault rather than simply replacing parts unnecessarily.

Step 3: Clear Explanation & Quote

We'll explain what's wrong, discuss your options and provide a transparent quotation before any work begins.

Step 4: Professional Boiler Repair

Once approved, we'll complete the repair using quality replacement parts where required and carry out full safety and performance checks before leaving your home.

Should You Repair or Replace Your Boiler?

Many homeowners assume a faulty boiler needs replacing, but that's often not the case.

If your boiler is relatively modern and the repair is cost-effective, repairing it is usually the most economical solution. We'll always aim to extend the life of your existing boiler where it's possible.

However, if your boiler is older, frequently breaking down or the repair costs are becoming uneconomical, we'll provide honest advice about replacement options. Our team will make honest recommendations based on what's best for you, not what would be most profitable for us.

Boiler Repair FAQs

Find answers to some of the most common questions about boiler repairs in Sheffield.

How quickly can you repair my boiler?

We always aim to respond as quickly as possible to boiler repair enquiries. Many faults can be diagnosed and repaired during our first visit, although this depends on the nature of the problem and whether replacement parts are required. We'll always keep you informed throughout.

How much does boiler repair cost?

The cost of a boiler repair depends on the type of fault, the parts required and the amount of work involved. Once we've diagnosed the problem, we'll provide a clear, transparent quotation before carrying out any repairs, so you know exactly what to expect with no hidden costs.

Is it worth repairing an old boiler?

That depends on your boiler's age, condition and the cost of the repair. If repairing your existing boiler is the most cost-effective option, we'll recommend that first. However, if a replacement offers better long-term value, we also provide professional boiler installation services. Our team can discuss your options and help you choose the right boiler for your home.

What boiler brands do you repair?

Our engineers have extensive experience repairing a wide range of domestic boilers from leading manufacturers. We regularly work on Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Viessmann, Potterton and many other brands. If you're unsure, simply get in touch.

Is it safe to use a faulty boiler?

If you suspect your boiler is unsafe, leaking or producing unusual smells, switch it off immediately and contact a Gas Safe registered engineer. Continuing to use a faulty boiler could pose a safety risk and may cause further damage. Never attempt to repair a gas boiler yourself.

Can an annual service help prevent repairs?

Yes. Regular boiler servicing helps identify worn or faulty components before they develop into more serious problems. Our boiler servicing also improves efficiency, helps extend the lifespan of your boiler and reduces the likelihood of unexpected breakdowns throughout the year.
