Boiler Repair FAQs
What types of boiler can you repair?
We repair combi, system and conventional gas boilers from the major manufacturers, including Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Vokera, Glow-worm and Ariston. Contact Simtec if your boiler brand is not listed.
How quickly can you attend a boiler repair in York?
Appointments are arranged as promptly as availability allows. When you contact us, explain the fault and whether you have lost heating, hot water or both, so we can assess the urgency of the problem.
Do you carry boiler spare parts?
Engineers may carry commonly required parts, but the correct component depends on the boiler model and the fault identified. Some parts may need to be ordered once the boiler has been inspected.
How much does a boiler repair cost?
The cost depends on the fault, the time required and whether replacement parts are needed. The problem and likely costs will be discussed before repair work proceeds.
Should I repair or replace my boiler?
Repair may be the sensible option when the boiler is otherwise in reasonable condition and suitable parts remain available. Replacement may need to be considered where the boiler is old, repeatedly breaking down or uneconomical to repair. Simtec will explain the available options before further work is agreed.
Can you repair a boiler that keeps losing pressure?
Yes. Pressure loss can be caused by leaks, faulty valves, expansion vessel problems or other system faults. The boiler and visible heating system components will need to be checked to identify the cause.
Can you repair boilers displaying fault codes?
Yes. A fault code helps indicate where the problem may be, but it does not always identify the precise cause. The boiler still needs to be properly diagnosed before parts are replaced or repair work begins.
How do I know whether my boiler is safe to use?
Turn the boiler off and seek advice if you smell gas, notice signs of burning, see water leaking into electrical components or suspect a carbon monoxide problem. Gas leaks should be reported immediately through the appropriate emergency service. Other faults should be assessed by a Gas Safe registered engineer.

⭐️⭐️⭐️⭐️⭐️
My boiler got written off so I needed a replacement. Simtec were round as soon as they could to have a look.
Much cheaper and with less disruption than other quotes proposed. I'm really pleased with the service, really clean and tidy with everything they needed to do (better nick than they found it!).
New boiler and flue installed in really good time, and they explained it all really well. Will be using Simtec for my services in future.
⭐️⭐️⭐️⭐️⭐️
Declan from Simtec fitted mum and our boiler services in straight away. Experienced, professional, good communication and friendly.

I would highly recommend. Thank you Declan and team.

Dek from Simtec Heating came to service our boiler and also fixed a couple of other plumbing issues we had around the house.
The service was fast, reliable, and carried out to a high standard.
Excellent customer care throughout – we would definitely recommend Simtec and will be using them again.
