Start with the jobs you want more of

Heating searches fall into a few clear groups, and each one needs its own page. A homeowner whose boiler has died in November is not reading the same page as a landlord who needs this year’s gas safety certificate, or someone weighing up a heat pump. One “services” page with a bullet list cannot rank for all of them.

Town pages done properly, not doorway pages

Most heating engineers cover a patch of towns and villages, and it makes sense to have a page for the main ones. The problem is how most firms do it: dozens of copies of the same page with the town name swapped. Google treats those as doorway pages, and they rarely rank for long. They also read badly to customers.

A town page that earns its place has things only you could write:

• Real installs you have done there, with a photo and the type of boiler fitted
• Local detail that affects the job, such as older terraces with back boilers, flats with flue restrictions, or areas off the gas grid where oil or heat pumps come up
• Reviews from customers in that town
• Which of your engineers covers it and roughly how quickly you can get there

Start with the handful of towns where you most want work and do them well. Add more only when you have real jobs to show.

Google Business Profile: categories and reviews

For “boiler repair near me” and “heating engineer [town]”, the map results often matter more than the normal listings. Your Google Business Profile drives them.

• Choose the primary category that matches the work you most want, such as heating contractor or boiler supplier, then add relevant secondary categories like plumber or gas engineer if they are true
• List each service with a short description, matching the pages on your site
• Set a service area that reflects where you actually go, and hide your address if you work from home
• Post photos of installs regularly, with the job described in plain words
• Ask every customer for a review, and ask them to mention the job: “new Worcester combi fitted in a day” is far more useful than “great service”
• Reply to every review, good or bad, briefly and politely

Gas Safe and accreditations, front and centre

Gas Safe registration is a legal requirement for anyone doing gas work, and customers increasingly check it. Show your registration number on every page, link to the Gas Safe Register check, and put engineers’ ID cards in photos where you can.

Manufacturer accreditations are trust signals, and they often come with longer guarantees that customers search for. If you are an accredited installer for Worcester Bosch, Vaillant, Viessmann, Ideal or another brand, give it a section on your boiler installation page and explain what the extended warranty means for the customer. MCS certification belongs on your heat pump page. None of these are required for SEO, but they help a nervous customer choose you once they land.

Seasonal content that matches the calendar

Heating has the most predictable year of any trade, and your content should follow it.

• Late summer: servicing reminders, “get your boiler checked before winter”
• Autumn: radiators not heating up, bleeding radiators, pressure dropping
• Winter: no heating, frozen condensate pipe, common error codes, emergency repair
• Spring: new boiler planning, heat pump surveys, replacing an old boiler while demand is lower

Publish these a few weeks before the season so they are indexed when searches rise. A short, useful article on a frozen condensate pipe can bring calls every cold snap for years.

Being named in AI answers

People now ask ChatGPT, Gemini, Perplexity and Google’s AI Overviews questions like “who fits boilers near me” or “is it worth repairing an old boiler”. AI assistants build answers from sources they can read and trust: clear answer-first pages, consistent business details across directories, reviews, mentions on other reputable sites, structured data and named experts. For a heating firm that means answering common questions directly on your pages, keeping your name, address and phone the same everywhere, using schema, and putting your lead engineer’s name and experience on the site. Nobody can guarantee being named, but these are the things that give you a chance.
