High-Intent Boiler Replacement Leads and Calls

The emergency and planned segments have almost nothing in common, and most campaigns blend them.

An emergency buyer has no hot water, possibly no heating, and a decision window measured in hours. They will take the first competent installer who answers the phone and can attend. Price sensitivity is unusually low. Speed is everything, and a callback tomorrow reaches someone who has already booked.

A planned buyer is doing the opposite. They are researching efficiency ratings, comparing warranties, weighing finance, and they will not be rushed. Push them to book an urgent survey and they disengage.

Run those through one campaign with one follow-up process and you lose the emergency buyer to whoever picked up faster, and irritate the planned buyer into going elsewhere.

Then there is the grant problem, which boilers share with solar. A meaningful share of enquiries come from people who believe a government scheme will pay for their replacement. Eligibility for schemes such as ECO4 is genuinely narrow and tied to specific benefit and property criteria, but the advertising in this sector has been loose enough that many households arrive expecting free.

And tenure, as always. Renters cannot commission a boiler replacement, however cold their flat is.

Split by urgency, and this is the clearest split in the whole portfolio.

Emergency demand is a calls product, full stop. Someone without heating in February is not filling in a form and waiting. They are phoning down a list until somebody answers. If your acquisition is form-based, you are structurally absent from the most profitable segment in this vertical.

Hot-key transfer is close to ideal for the emergency segment. No callback gap, no decay, and the buyer is grateful rather than annoyed to be connected immediately.

IVR qualification handles the two killers in seconds. Homeowner status and postcode for coverage, asked before your engineer or call handler picks up. That removes tenants and out-of-area enquiries without anyone having an awkward conversation about it.

Planned replacement suits forms and nurture. These buyers want efficiency data, warranty comparisons and finance options. Data capture with a genuinely useful follow-up sequence serves them properly, and they convert well over weeks rather than hours.

Because calls bill on connected duration past a buffer, and because the emergency segment converts at a much higher rate, running calls and leads on separate targets is not optional here. Blending them produces a blended number that describes neither.

Paid search. The dominant channel, and where the urgency split is visible in the query itself. "Boiler replacement quote" and "new boiler cost" are planned buyers. "Emergency boiler repair", "boiler not working" and "no hot water" are the other market entirely. Separating those into different campaigns with different follow-up is the single highest-impact change most boiler advertisers can make.

Pay-per-call networks. Where the emergency segment lives. This is the vertical where a calls product most obviously outperforms a leads product.

Owned comparison properties. We operate comparison and review properties, so boiler demand can be met on our own estate. A homeowner comparing installers has accepted they are replacing rather than repairing, which is the decision that matters.

Paid social. Better for the planned segment and for pre-winter demand generation than for emergencies, since nobody discovers their boiler has failed via an advert. Requires homeowner gating in the ad flow.

Content and organic. Genuinely useful for the planned buyer. How boiler sizing works, combi against system, what warranties actually cover, whether a repair is worth it at a given age. Households research this properly because it is a four-figure purchase they make roughly once a decade.

Email and consented data. Best used seasonally, ahead of the first cold snap, and to re-engage households who enquired in spring and deferred.

Boiler demand is the most seasonal in our portfolio and it is not a gentle curve. Demand climbs as temperatures fall and spikes hard during the first sustained cold period, because that is when marginal boilers finally fail.

That has three practical consequences. Media costs rise sharply in that window, so campaigns should be built and tested before it, not during. Installer capacity becomes the binding constraint rather than lead volume, and generating enquiries an installer cannot service within a week converts them into complaints. And the quiet months are when planned replacement should be pushed, because a household that upgrades in August is a household that does not become an emergency in January.

Marketing that only switches on when it is cold is competing at the most expensive moment against everyone else doing the same thing.

The repair-against-replace row is worth attention. A household with a six-year-old boiler and a faulty diverter valve needs a repair, and an installer who arrives to quote a full replacement has wasted a visit and left a poor impression. Identifying age and fault type at enquiry routes those correctly and protects the relationship.

Gas work is safety-critical and the rules reflect that.

In the UK, anyone carrying out work on gas appliances must be Gas Safe registered. It is a legal requirement, not a quality badge, and marketing should never imply registration a business does not hold or blur the line between a registered installer and a lead generator.

Government scheme references are the other risk area. Eligibility for energy efficiency schemes is narrower than the advertising in this sector often suggests, and households who arrive believing they qualify for a free boiler and discover otherwise generate complaints and waste survey time. Efficiency and savings claims should be modelled and caveated rather than presented as guaranteed, since actual savings depend on the property, the old system and how the household uses heating.

Where finance is offered, credit promotions carry FCA obligations including representative examples.

Our position: no free boiler framing, no implied scheme eligibility, no unqualified savings claims, and clear separation between the installer and the introducer. Enterprise energy brands audit their acquisition suppliers, and this is a category where a complaint can attract more than commercial consequences.

Enquiry volume is close to useless during a cold snap, when everything looks like it is working.

We report on:

Cost per contacted enquiry, reported separately for emergency and planned.

Cost per qualified conversation. Homeowner confirmed, in coverage, replacement rather than repair.

Cost per booked survey or attendance.

Cost per completed installation. The figure that maps to revenue.

Emergency conversion rate against planned. These should never be blended. Emergency converts far higher and is worth more per enquiry, and averaging the two hides which channel is doing the work.

Speed to answer on the calls product. In the emergency segment this predicts conversion more strongly than anything else.

Installation outcomes are fed back to the platforms rather than form submissions, so campaigns learn what a household that actually installs looks like rather than who is most willing to enquire.
