What's actually included in a boiler service?
Combustion analysis, flue integrity check, gas tightness test, inspection of seals and pipework, a check of controls and thermostats, and a pressure and expansion vessel check. You get documentation on completion recording what was tested.
Do you guarantee your work in Renfrew?
Every repair, service and installation we carry out in Renfrew carries a 12-month workmanship guarantee. If something we've worked on fails within that period we come back and put it right — and since Renfrew is on our regular route, returning is straightforward. Manufacturer warranties on new parts and boilers run alongside ours.
Is a service the same as a CP12?
No, and it's worth understanding the difference. A CP12 confirms gas appliances are safe to use, which is the legal requirement for landlords. A full service goes further, covering efficiency and wear items. Many landlords book both together in one visit.
How often should a boiler be serviced?
Once a year is the standard recommendation, and most manufacturers require it to keep the warranty valid. For Renfrew landlords the annual gas safety check is a legal requirement regardless. Booking in late summer usually gets you a better choice of slots than waiting for the first cold snap.
How long does a service take?
Usually 45 minutes to an hour for a single boiler, assuming reasonable access and no faults found. A CP12 covering several appliances takes a bit longer.
What should I do if I smell gas at my Renfrew property?
Treat it as an emergency. Leave the property, don't touch light switches or anything that could spark, and call the National Gas Emergency Service on 0800 111 999 straight away — before calling us. They attend free, around the clock, and will isolate the supply if needed. Once it's safe, we'll come out to repair the pipework or appliance, and about 20 minutes from us.
Will servicing void or protect my warranty?
Protect it. Most manufacturers require documented annual servicing as a warranty condition — skip a year and a future claim can be refused even if the fault is unrelated. Keep the paperwork we give you.
Do I need to be home for the engineer?
Someone over 18 needs to provide access and be there while gas work is carried out at your Renfrew property. If you're arranging it for a tenant or an elderly relative, that's fine — just give us their contact details when you book so we can coordinate directly.
When is the best time of year to book?
Late summer or early autumn. Everyone books in the first cold week of the year, so slots get tight exactly when you most want one. Servicing before the heating season starts also means any fault found is fixed before you depend on it.
Why is my boiler losing pressure?
Most often a small leak somewhere in the system, a worn pressure relief valve, or a failing expansion vessel. Topping up occasionally is normal; needing to do it every few days is not. Given the age of the heating in many Renfrew properties, a pressure test is usually the quickest way to find the cause.
