Choosing the Right Boiler for Your Home
Upgrading or replacing your boiler is an important decision. With so many types and brands to pick from, it can feel overwhelming. Ultimately, you want a quality boiler from a reputable company that will suit your budget and needs.
British Gas remains one of the most trusted names in boiler installations across the UK. With over 200 engineers operating across the country, they have the expertise to advise which boiler is best for your home and handle the installation.
British Gas Boiler Warranties and Certifications
All British Gas engineers are Gas Safe registered, so you know you’re getting a qualified professional. Their boilers also come with warranties up to 10 years, providing peace of mind should anything go wrong.
They partner with leading boiler manufacturers like Worcester Bosch to ensure the units installed meet rigorous quality and safety standards. Look for the CE certification mark.
Boiler Costs and Financing
British Gas offers boilers across a range of budgets. Expect to pay anywhere from £500 for a basic combi boiler to £2,500 for a more advanced model. Installation costs extra.
If the upfront expense is too high, consider their boiler finance plans. You can spread payments over 3-10 years. Just be sure to read all terms and eligibility criteria first.
The Boiler Installation Process
Once you pick your new boiler, a British Gas engineer will arrive to inspect your property, suggest suitable locations for the unit, and confirm any prep work needed. This normally takes up to 90 minutes.
On installation day, count on the job taking 1-2 days with potential plumbing upgrades. The engineer will test the boiler before leaving to ensure everything is working properly.
Aftercare and HomeServe Protection Plans
British Gas won’t leave you high and dry. All their boilers come with at least one free annual boiler service to give you extra assurance. You can add on service plans to cover additional maintenance visits and parts if issues surface down the road.
They also partner with HomeServe to offer boiler repair coverage starting around £5/month. This can offset costly one-off repair bills later on.
