Choosing the best Ideal boiler

All boilers with an Ideal+ warranty offer customers a free five-year parts and labour repair service. To qualify for the full five years of the warranty, the boiler must be registered within 30 days of installation and be serviced annually by a competent person (Gas Safe registered engineer). Should either of these conditions not be met, the period of warranty will extend to only 12 months from installation. All boilers with a Standard Ideal Warranty offer a free two-year parts and labour repair service.

If the boiler suffers a mechanical or an electrical breakdown, contact Ideal on one of the following numbers:
