Is Your Boiler Due for a Service?

Most boiler manufacturers recommend an annual service to keep your boiler running safely and efficiently. Skipping a service can also affect your warranty, with many manufacturers requiring evidence of annual servicing for warranty claims to be valid.

An annual boiler service from Gas Wise includes a full safety inspection, performance check, and any necessary cleaning or adjustments, giving you peace of mind that your heating and hot water are ready for the year ahead.

Ruth Lewis

Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

Luke Taylor

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

John Robinson

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up.

Alison Taylor

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy.

David Stemp

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Jess Slater

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks

FAQs

How long does a boiler service take?

A standard boiler service typically takes between 45 minutes and an hour, depending on the boiler type and condition. During the visit, our engineer will carry out a full safety inspection, clean key components, and identify any issues that may require attention.

How do I know if my boiler needs repairing or replacing?

If your boiler is under 10 years old and the fault is isolated, a repair is usually the most cost-effective option. For older boilers that are breaking down regularly, losing efficiency, or requiring expensive parts, replacement is often the better long-term investment. Our engineers will always give you an honest assessment.

Do you work on older boiler models?

Yes, wherever parts are available, we are happy to work on older systems. If a boiler is beyond economical repair, we will explain your options clearly and provide a no-obligation replacement quote.

How often should I have my boiler serviced?

Once a year is the standard recommendation, and is often a condition of your boiler warranty. We recommend booking a service in late summer or early autumn before the heating season begins.

Do you offer emergency boiler repairs?

Yes. We provide emergency boiler repair services across Oxfordshire and surrounding counties. If your boiler breaks down, contact us on 01295 597 961, and our team will respond as quickly as possible.

Can you service oil and LPG boilers as well as gas?

Yes. Our OFTEC-registered engineers are qualified to service, repair, and install oil and LPG boiler systems, as well as gas. This makes us a practical choice for homeowners in rural areas who are off the gas grid.
