Why Service Your Boiler Every Year?

Most homeowners only think about their boiler when it stops working. By that point — usually on the coldest night of the year — you are already facing an emergency call-out and potentially days without heating or hot water.

An annual boiler service from AN Plumbing & Heating catches problems before they become breakdowns. Our GAS Safe registered engineers carry out a thorough inspection and clean of your entire heating system, checking every component against manufacturer specifications and current gas safety standards.

A well-maintained boiler also runs more efficiently — which means lower gas bills. Boilers that have not been serviced can lose efficiency year on year, costing you more to run without you even noticing.

  • Keeps your manufacturer warranty valid
  • Identifies carbon monoxide risks before they become dangerous
  • Improves efficiency and reduces gas bills
  • Catches developing faults before they cause a breakdown
  • Written service record provided on completion

What's Included in a Full Service

✔

Visual & Component Inspection

Full check of boiler casing, pipework, seals, and all internal components for signs of corrosion, wear, or damage.

✔

Flue Gas Analysis

Digital emissions testing to confirm the boiler is burning gas cleanly and safely — the most important safety check in any service.

✔

Gas Pressure & Valve Checks

Working gas pressure tested and all safety valves confirmed to be operating correctly within specification.

✔

Internal Clean

Removal of the casing to clean the heat exchanger and burner, removing debris that reduces efficiency and can cause faults.

✔

Flue & Ventilation Check

Inspection of the flue terminal and ventilation to ensure combustion gases are safely expelled from your property.

✔

Written Service Record

A full written service record issued on completion — essential for warranty claims and useful when selling your home.

Landlords & Property Managers

Boiler Servicing for Middlesbrough Landlords

If you own rental properties across Teesside, keeping on top of annual boiler servicing is both a legal obligation and a practical necessity. A well-maintained boiler means fewer emergency tenant call-outs, lower repair costs, and a safer property.

We work with landlords managing single properties and large portfolios across Middlesbrough, Stockton, Redcar, and the wider Teesside area. We can combine your annual boiler service with a CP12 Landlord Gas Safety Certificate in a single visit — saving you time and reducing disruption to your tenants.

Common Questions

Everything you need to know about our boiler servicing in Middlesbrough.

How often should I get my boiler serviced?
Your boiler should be serviced once every 12 months by a GAS Safe registered engineer. Most boiler manufacturers require annual servicing as a condition of keeping your warranty valid. Regular servicing also helps prevent unexpected breakdowns, particularly in winter.
What is included in a boiler service?
A full boiler service includes a visual inspection of all components and pipework, flue gas analysis using digital equipment, gas pressure checks, safety valve tests, internal cleaning of the heat exchanger, a check of all seals and gaskets, and a written service record on completion.
Will missing a service void my boiler warranty?
Most manufacturers including Worcester Bosch, Vaillant, and Baxi require annual GAS Safe servicing to keep the warranty valid. Missing a service can void your warranty, leaving you liable for the full cost of repairs. Always check your boiler's warranty terms — we can advise when we visit.
Do you offer boiler servicing for landlords?
Yes. We service boilers across landlord properties throughout Teesside. A boiler service and a CP12 landlord gas safety certificate are two separate things, but we can carry out both in the same visit to save you time and minimise disruption for your tenants.
How long does a boiler service take?
A thorough annual boiler service typically takes between 45 minutes and one hour. We will confirm a convenient appointment time and our engineer will work efficiently to minimise disruption to your day.
Can a boiler service prevent a breakdown?
Yes. During a service we identify worn components, developing faults, and efficiency issues before they cause a complete breakdown. Catching these early is significantly cheaper than an emergency call-out — particularly in winter when demand for engineers is at its highest.

Due for a Service?

Don't wait until winter. Book your annual boiler service today and keep your heating running safely and efficiently all year round.
