Best marketing agencies for heating engineers in the UK

Criteria built around the heating calendar

Heating marketing has to do two jobs. In the cold months it has to catch urgent calls, many of them out of hours, when a homeowner will ring the next firm within a minute if nobody answers. In the warm months it has to generate planned work: boiler replacements, servicing plans, heat pump enquiries, which are researched online and won on trust and quote quality.

We ranked these five agencies on out-of-hours and missed-call capture, planned-work presentation (service pages, Gas Safe prominence, quote process), local search strength, pricing and contract terms, and the heating-specific evidence on their own websites. Where an agency publishes a boiler installer result, we say so.

1. Riley Marketing

Best for: Independent heating engineers and small firms wanting winter capture and summer pipeline from one system

Riley Marketing names heating engineers among its core trades and its fixed-fee system handles both halves of the heating year. For winter, missed call text back replies instantly to any caller who hits voicemail, so a no-heating customer gets a text while you are on another job rather than ringing the next firm. Google Business Profile optimisation and automated review requests build the map pack presence that urgent searches depend on.

For summer, the SEO-focused website carries a page for each service and each town, so 'boiler replacement' or 'heat pump installation' plus your area has a page to rank. The CRM tracks each enquiry and sends branded quote pages on your own domain, which is where a £3,000 boiler job is won against two other quotes. The review automation also includes a reactivation campaign for past customers, and a heating engineer with a few hundred annual services behind them has an unusually large pool to draw on.

The price is £149 a month at the time of writing, fixed, with the site built before you pay, no setup fee, unlimited revisions and no contract. Founder Tom Riley, with ten years in search and lead generation behind him and his own lead generation sites still running, works with clients directly. Google Ads and Meta ads are add-ons for engineers who want to push boiler replacements in the shoulder months.

2. Get Work

Best for: Heating engineers who want Google Ads leads delivered through a managed platform

Get Work in Lytham St Annes is a Google Partner that builds a dedicated landing page and Google Ads funnel for each tradesperson, with plumbing and heating among its many named trades. Leads arrive by text notification into its lead management and job booking platform, which shows spend against job value on a dashboard, and the agency says its pages convert far better than typical home improvement sites and that leads are exclusive.

For a heating firm wanting a predictable flow of boiler quote requests in the quiet months, paid search through a managed platform is a sensible tool. Pricing sits on a separate page, and the published case study is a roofing company's first-month revenue and ROI rather than a heating client. Who is Get Work covers the questions to ask.

3. SanXpert Digital

Best for: Gas engineers wanting Google Ads and Google Business Profile on a fixed fee with out-of-hours AI capture

SanXpert Digital says it works exclusively with trade businesses and has done so for 12 years, naming gas engineers and boiler installers among roofers, plumbers, electricians and others across 80-plus UK towns. Its claim to build campaigns around trade-specific sales cycles, emergency versus replacement, is precisely the heating distinction that matters, and its AI automation for out-of-hours lead capture addresses the winter call problem.

It charges a fixed monthly fee with no percentage of ad spend, rolling monthly with no contract, though prices are not published. Published proof is limited to a roofing testimonial. A heating engineer should ask for a boiler installer reference before committing. Our SanXpert Digital profile has more.

4. LeadFly

Best for: Heating firms losing winter callouts to voicemail

LeadFly in Watford works exclusively with UK trade businesses and references Gas Safe terminology on its site. Its products are AI voice agents for 24-hour answering, website chatbots, workflow automation for quote chasing, reminders and review and referral requests, and short-form video. Published prices include chatbots at £99 a month, an AI receptionist at £299 a month plus setup and videos at £299 a month.

It is not a lead generation or SEO agency, so it only makes sense for a heating firm whose phone already rings. For such a firm, an AI receptionist that books the no-heating call at 7pm could pay for itself quickly in January. No case studies are published, only an unattributed savings claim.

5. TradesGrow

Best for: Heating and boiler specialists in Wales and beyond wanting mixed PPC, Facebook and local SEO

TradesGrow in Cardiff lists plumbers and gas engineers and heating, HVAC and boiler specialists at the top of its trades, and its published results include a boiler installer alongside roofers, a landscaper and a driveway company. It runs Google PPC with call tracking, Facebook ads, local SEO including Google Business Profile, citations and review generation, web design and done-for-you lead generation.

It offers a free strategy call and audit, says first leads are free on its lead-gen offers, and shows indicative cost-per-lead figures in its portfolio. A pricing page exists but tiers are not displayed on the homepage.

Winter and summer readiness compared

Which should a heating engineer choose?

A sole trader or small heating firm should start with Riley Marketing. It builds the local search presence for winter, the service pages for summer and the quote process that wins boiler jobs, and it handles missed calls, all for a fixed £149 a month with nothing paid until the site exists. Why fixed fee beats retainers for trades explains why that structure suits a seasonal trade.

A firm that wants to buy boiler quote requests in the shoulder months can add Get Work or SanXpert Digital for paid search, with SanXpert's fixed-fee, no-percentage model being the more predictable of the two on paper. TradesGrow is the one with a published boiler installer result and belongs on any Welsh heating firm's shortlist.

LeadFly is the exception: not a growth agency but a plug for the winter leak of unanswered calls, best added to a working foundation. Set a 90-day checkpoint with whoever you choose and judge them on booked boiler jobs, not clicks. For the wider market, our UK trades marketing agency ranking covers more options, and do tradespeople need an agency at all is worth reading before you spend.
