Why it matters

Why an annual service matters

Keeps your boiler safe

The engineer checks for problems that could affect how your boiler burns gas or removes fumes. Every home with a gas boiler should also have a working carbon monoxide alarm.

Helps prevent breakdowns

A service can’t guarantee your boiler won’t fail, but it can spot developing faults early. That matters most in winter.

Keeps your boiler efficient

Worn parts and developing faults can make your boiler work harder than it needs to.

Protects your warranty

Most manufacturers ask for a service every 12 months, so keep your service records. Check your own boiler’s warranty terms.

Service costs

How often

How often should a boiler be serviced?

Once every 12 months. Many people book in autumn, before the heating goes on for winter. Any time of year is fine, as long as you keep to a regular schedule.

Landlords in Scotland

If you rent out a property, you must have every gas appliance and flue checked each year by a Gas Safe registered engineer, and give your tenants a copy of the gas safety record.

A gas safety check is not the same as a full boiler service. The safety check makes sure appliances are safe to use. A service is maintenance carried out to the manufacturer’s instructions. Many landlords book both at once. See Saltire landlord cover.

From start to finish the services has been exellent. Initial chat, no hard sell just information and advice to enable me to make an informed choice.

We had an issue with low water pressure in our boiler, which meant no heating or hot water. Called Saltire and they sent an engineer out same afternoon. Identified issue and made repairs quickly and effectively.

Just had saltire out to put new boiler in our house. Class work done, engineers done a fantastic job – 10 out of 10.

I’m with trust housing and had a gas leak so the guys from Saltire were called in. John and Ross went above and beyond to track and repair the fault I can’t recommend this company enough.

This company have been marvellous. My mum (who has now passed away) had great service from Saltire. They were always so prompt coming out when she needed help with her boiler.

Really outstanding service. A real cut above the rest when dealing with central heating companies in the past.
