Authorised Rational Service Partner — Factory-Trained Engineers in London & the Home Counties
What this means for you: genuine parts, manufacturer-backed repairs, and engineers who are trained and authorised by Rational — not just experienced with their equipment.
What is a Rational Service Partner?
Rational AG appoints a limited network of approved service firms in each market. To become an authorised Rational Service Partner, a company must put its engineers through Rational's own factory training programme, demonstrate the technical capability to work on the full product range, and meet Rational's standards for parts handling, safety compliance and customer service.
Partners receive direct access to Rational's technical support team, proprietary diagnostic tooling, and OEM parts supply chain. They are also authorised to carry out warranty repairs on Rational's behalf — something only a partner can do.
GasTech Inc Ltd holds current Rational Service Partner status and covers London and the Home Counties. Our engineers are factory-trained, Gas Safe registered, and have direct access to Rational's technical and parts teams.

Our Engineers
Our engineers have been working on Rational combi ovens since the SelfCookingCenter era. That depth of experience matters when diagnosing complex faults on older units.

All our engineers are individually Gas Safe registered. You can verify any engineer's registration number with the Gas Safe Register before they attend site.

Authorised Rational Service Partner — FAQ
Are you the same as Rational UK?
No. We are an independent company — GasTech Inc Ltd — that holds authorised service partner status granted by Rational. We are not Rational UK's in-house team, but we are officially approved and authorised by Rational to carry out warranty and out-of-warranty repairs, use their diagnostic tools, and source OEM parts through their supply chain.
Do I have to use a Rational Service Partner?
You are not legally required to use an authorised partner for out-of-warranty repairs. However, using an unauthorised engineer risks voiding your warranty, the use of non-OEM parts, and work that Rational will not back. For in-warranty repairs, Rational requires an authorised partner to preserve warranty coverage.
How do I find an authorised Rational engineer in my area?
You're in the right place. GasTech Inc Ltd covers London and the Home Counties. Call us on 0203 887 1728 or book online. We offer same-day callout availability for breakdowns and scheduled visits for servicing.
Do you handle warranty claims directly with Rational?
Yes. As an authorised service partner, we liaise directly with Rational for warranty claims. If your equipment is within the manufacturer's warranty period, we can assess the fault, determine warranty coverage, and process the claim with Rational on your behalf.
