Local support in The Denes

Practical information about our coverage, services and heat pump support.

The Denes is one of Darlington's most established residential pockets, a leafy stretch of semi-detached and early-1900s terraced housing that follows the wooded valley of the Cocker Beck between Cockerton and High Northgate. It's an area of solid, well-built homes, plenty of them approaching their second century, and that age brings specific questions when it comes to switching away from an old gas boiler to a heat pump.

Heat Pump Installation in The Denes

Older semis and terraces around The Denes often have smaller original radiators and solid or part-solid walls, so before we install anything we work out the property's heat loss, check radiator sizing and look at hot water demand. That groundwork decides whether a home needs bigger radiators, extra insulation, or simply a well-sized heat pump to run efficiently. A house backing onto the Cocker Beck valley can lose heat differently to one facing Woodland Road, so we treat each survey as its own job rather than reusing a neighbour's specification.

Why The Denes' Period Homes Suit Heat Pumps

Despite their age, a lot of the housing stock around The Denes, Faverdale and Mowden responds well to a heat pump once it's set up with the right flow temperatures. Lower running noise than an old boiler, no flue to maintain, and a system designed around the specific property rather than fitted as a one-size-fits-all replacement. For homeowners weighing up a period property against an unfamiliar heating system, that individual approach tends to be the deciding factor.

Annual Heat Pump Servicing in The Denes

Every ATE annual service is a proper service, not a quick visual check: full safety and efficiency checks, a system water and glycol quality assessment, and a PDF report handed over afterwards to keep your manufacturer's warranty valid. Choose from our Heat Pump Only, Heat Pump & Cylinder or Hybrid plans — simple monthly pricing is on our plans page. Skipping a year can let small problems go unnoticed, so we keep every property on the same annual cycle regardless of how new or old the system is.

Air source heat pumps

ASHP Servicing, Air Source Heat Pump

Air source heat pump servicing — usually shortened to ASHP servicing — is the annual visit that keeps your system running the way it was designed to. Our engineers cover The Denes as part of our wider County Durham service area, looking after air source heat pumps in new-build homes, older retrofitted properties and rural houses off the mains gas network.

Why an air source heat pump needs servicing every year

An air source heat pump does not burn fuel. It moves heat from the outside air into your heating and hot water, which is what makes it efficient — and also why faults rarely announce themselves. Slightly low system pressure, weak glycol, a restricted outdoor coil or a flow temperature left higher than it needs to be will not usually stop the heating. It will quietly raise what the system costs to run. An annual ASHP service is how those issues get found while they are still small.

Most heat pump manufacturers also expect the system to be serviced once a year for the warranty to stay valid. After every visit in The Denes you receive a PDF service report setting out the checks carried out and the condition of the system, so you have the documentation to hand when you need it.

Air source heat pump systems we service in The Denes

  • Air-to-water monobloc heat pumps
  • Split system air source heat pumps
  • Heat pump and hot water cylinder setups
  • Hybrid heat pump and boiler systems

Not sure which of these describes your setup? Our heat pump maintenance plans are split along the same lines, so you can match the plan to the system you actually have in The Denes.

Maintain efficiency

A well-maintained air source heat pump is more likely to run smoothly and avoid wasting energy through the winter.

Protect comfort

Annual checks catch developing faults before they turn into a heating or hot water problem.

Keep records

Your PDF report gives you a dated record of the service visit and the condition of the system.

Annual maintenance

Heat pump servicing built for long-term performance

A heat pump is a long-term investment. Regular checks help identify smaller issues before they become larger, more expensive problems.

Every service includes safety and efficiency checks, a system water and glycol assessment, and a detailed PDF report to support your manufacturer’s warranty records.

Frequently asked questions

Helpful answers about our service coverage, maintenance plans and the support available in The Denes.

6 questions answered
Do you cover The Denes and the rest of Darlington?

Yes. Alongside The Denes we regularly work across Darlington, including Cockerton, High Northgate, Faverdale and Mowden. Just mention your street when you call and we'll confirm coverage.

Are you a Darlington-based company?

We're based in Guisborough, with a second office in Whitby, but our engineers regularly cover Darlington and the wider County Durham area, including The Denes, as part of our normal patch.

Will a heat pump suit an early-1900s semi in The Denes?

Usually, yes, with the right design. We check wall construction, existing radiator sizes and insulation levels first, since older Denes properties sometimes need slightly larger radiators to work well with lower heat pump flow temperatures.

What's involved in the annual service?

Full safety and efficiency checks, an assessment of your system's water and glycol quality, and a PDF report at the end of the visit. That report is what you'll need on file to keep your manufacturer's warranty valid.

Can you take over servicing a heat pump that's already installed in The Denes?

Yes. We regularly bring systems installed by other companies onto one of our maintenance plans, after first checking the installation and any available service history.

How do I book?

Call or email us during office hours, Monday to Friday 9am to 5pm, and we'll arrange a suitable date for a service or an installation visit.
