Frequently Asked Questions

Which brand do you recommend?

As accredited installers for both brands, we recommend based on your specific needs. For most customers, either is excellent. We often suggest Worcester for its warranty and Vaillant for its efficiency.

Are there cheaper alternatives?

Yes - Ideal, Baxi, and Glow-worm offer good value. However, for longevity and peace of mind, we believe the premium for Worcester or Vaillant is worthwhile. The extra cost is recovered in reliability.

How important is the warranty?

Very important. A boiler is a significant investment (£2,000-£4,000 installed). Extended warranties protect against expensive repairs in years 3-10 when problems are most likely.

Can you install both brands?

Yes, we're accredited installers for Worcester Bosch, Vaillant, Ideal, and Baxi. This means we can offer extended warranties on all major brands.
