Heat Pumps in Sevenoaks — the Local Picture

Sevenoaks has one of the higher concentrations of air source heat pumps in West Kent, and for a clear reason: a lot of larger, older, off-gas and part-rural properties across Otford, Kemsing, Seal, Halstead and the lanes around Dunton Green, plus a steady run of Boiler Upgrade Scheme retrofits into substantial family homes in TN13 and TN14.

Bigger properties are exactly where poor commissioning shows up worst. A heat pump that is merely adequate in a small modern house becomes an expensive disappointment in a five-bedroom period home if the settings are wrong.

"It never really gets the house warm"

Usually flow temperature and weather compensation, not capacity. Larger homes with mixed radiator sizes need the curve set properly — and on a great many systems I visit, weather compensation is simply switched off.

Running costs far above what was quoted

The single most common complaint. Flow temperature left at 50°C or more on handover day, when the same house would run happily at 40–45°C. Tuning that is an optimisation visit, not a replacement.

Glycol and freeze protection

Rural and exposed Sevenoaks properties genuinely need this checked. Weak glycol concentration risks frozen external pipework in a hard Kent winter, and it is a five-minute test that gets skipped constantly.

Installer no longer around

A recurring theme with 2021–2023 grant-era installations. I service and take over systems regardless of who fitted them, and check the warranty terms so your cover stays intact.

Sevenoaks Heat Pump Questions

Yes — across TN13, TN14 and TN15, including Riverhead, Dunton Green, Otford, Kemsing, Seal and Halstead. ASHP Level 3 qualified, all major brands, whoever installed the system.
£170 with no VAT for a full annual service with a written report. Combined with an unvented cylinder service in the same visit it is £270, saving £40.
Usually yes, and usually without new hardware. Larger Sevenoaks properties are often heated by a system sized or commissioned for a smaller heat demand, or running with weather compensation disabled. Both are settings problems, not equipment failures.
Yes, along with Vaillant aroTHERM, Samsung, Grant, Worcester Bosch, Panasonic and LG. I service them regardless of who installed them and check your warranty terms first.
Yes, on two counts. Most manufacturers require documented annual servicing to keep a five to seven year warranty valid, and an unserviced system quietly drifts toward higher running costs long before it actually breaks down.
Yes, and it is arguably the better time — you are not without heating if something needs ordering, and my diary is easier.
No. On a monobloc the refrigerant circuit is factory sealed, and routine servicing to the manufacturer's schedule does not normally involve opening it. The work is the water side, controls and electrics, which is where faults actually occur.
I explain what I am changing and why first. They are your bills. If you would rather I left something alone, I note that in the report.
Ideally yes. I want to hear how it has been running, and afterwards I will walk you through what changed and why — understanding your controls is worth real money.
Often more so. Grant-era installations are exactly where I find fixed high flow temperatures and weather compensation switched off from day one.

Warning Signs

When to Get It Checked

Very few heat pumps fail suddenly. They drift, quietly, and the bill is usually the first thing anyone notices.

Warm radiators but the house never gets there

Often the compensation curve set too shallow, so flow temperature never rises enough on genuinely cold days.

Glycol never checked since installation

Not a symptom you will notice until pipework freezes. Worth testing annually on any exposed or rural installation.

A new noise

Fan and defrost noise is normal. A new whine, rattle or vibration is not — bearings, a loose panel or a perished anti-vibration mount. Cheap early, expensive later.

Bills higher than you were told to expect

The commonest complaint, and almost always settings rather than a fault. Flow temperature and weather compensation are the first things I look at.

Fault codes appearing and clearing themselves

Intermittent codes are worth noting rather than dismissing. They usually precede a hard fault by weeks or months.

Costs

Prices and What You Get

An optimisation visit includes before and after readings in writing. If the numbers do not improve I will tell you that, rather than claiming a saving I cannot evidence.

Most heat pump problems I attend need no parts at all, because they turn out to be settings rather than failures. Where parts are needed I quote a fixed price before ordering.

Heat pump and unvented cylinder serviced in one visit is £270 rather than £170 and £140 separately — £40 saved, and it means one engineer sees the whole system rather than half of it.
