🛒 Buying a combi oven
What does refurbished actually mean at CaterCombi? ▾
Every oven goes through our comprehensive 57-point planned preventative maintenance schedule before being listed for sale. This includes a full clean, replacement of worn parts, recalibration, and a working test. You receive the full service checklist and a list of all parts changed — and you can see the oven working via video call or by visiting our Canterbury warehouse.
What warranty do I get with a purchased oven? ▾
All sales come with a 3-month parts-only warranty. If we can't supply the required parts, we'll provide a replacement machine of equal or better specification. If we can't supply a replacement, we'll issue a full refund. Extended warranties are available on request.
Can I see the oven working before I buy? ▾
Yes. All our refurbished units have real photos and videos on our website. You are also welcome to visit our warehouse in Canterbury, Kent or arrange a video call demonstration if you'd prefer to see it remotely before committing.
What brands do you stock? ▾
We stock refurbished combi ovens from all the major manufacturers including Rational, Convotherm, Electrolux, Lainox, Unox, Hobart, Eloma, Bonnet, Lincat, and MKN. Rational is our most popular brand. We always have 150+ ovens in stock across gas and electric models.
What sizes are available? ▾
We stock the full range — from compact XS countertop units right up to 40-grid roll-in floor models. The most common sizes we sell are 6-grid, 10-grid, and 20-grid. If you don't see the exact size or model you need listed, call us on 01227 469692 as we have a high stock turnover.
Do you deliver, and how much does it cost? ▾
Yes — we deliver by pallet to anywhere in the UK for £75. Items can also be collected from our Canterbury warehouse free of charge. For larger or stacked units, contact us to discuss delivery arrangements.
What payment methods do you accept? ▾
We accept all major credit and debit cards including Visa, Mastercard, American Express, and Maestro, as well as Apple Pay, Google Pay, and Shop Pay. We also offer iwocaPay at checkout for business finance options.
Can I part-exchange my old oven? ▾

📅 Renting a combi oven
What is included in a CaterCombi rental? ▾
Every rental includes the oven itself, full professional installation by our trained engineers, all ongoing maintenance and servicing, priority engineer support for breakdowns, and full compliance documentation. There are no hidden costs — just a fixed monthly payment.
How much does it cost to rent? ▾
Rental starts from £44 + VAT/week (≈ £6.27/day) for the XS compact model, up to £79 + VAT/week for the 20-grid. All prices include full installation and maintenance. Visit our Rent an Oven page for full pricing.
What is the minimum rental term? ▾
Our minimum rental term is 2 years. This allows us to offer competitive weekly rates with all maintenance included throughout the term.
What areas do you cover for rental? ▾
We currently offer our rental service across the South East of England, covering Kent, Surrey, Sussex, Hampshire, London, Essex, Hertfordshire, Berkshire, and Oxfordshire. Not sure if you're in our area? Just get in touch.
What happens if the rented oven breaks down? ▾
All rental customers receive priority engineer support. If your oven develops a fault, we'll send an engineer as quickly as possible. Rental customers must log a service request via our Service Request page.
Can I buy the oven at the end of the rental term? ▾
This is something we can discuss at the end of your term. Get in touch with us to find out what options are available to you.
🔧 Service & repair
My oven is showing an error code — what should I do? ▾
Note the error code and include it when logging a service request. If you can, take a photo of the display and send it to us on WhatsApp — this helps us diagnose faster and may allow us to resolve it remotely without an engineer visit.
I'm a rental customer — how do I log a repair? ▾
Use our Service Request page to log the fault. We aim to respond within a few hours on working days. For urgent faults where the oven is completely non-operational, call us directly on 01227 469692.
Will I be charged for a repair? ▾
Rental customers have maintenance and repairs included at no extra cost, provided the fault isn't caused by misuse or external infrastructure. Sales customers within their 3-month warranty are covered for parts. We'll always be upfront about any charges before work begins.
What faults aren't covered by warranty or rental contracts? ▾
The following are outside our standard coverage as they relate to infrastructure rather than the oven itself: insufficient water supply, blocked drainage beyond the machine connection, electrical or gas supply faults, external heat sources within 30cm, and damage from misuse, neglect, or unauthorised modification.
I'm out of warranty — can CaterCombi still fix my oven? ▾
Unfortunately we can't carry out repairs outside of active rental or warranty agreements. Our engineering resource is reserved for contracted customers. Visit our Find an Engineer page for a directory of qualified independent engineers, or use the Rational Service Partner network if you have a Rational oven.
How do I clean and maintain my combi oven? ▾
Most modern combi ovens have automated cleaning cycles — but you should also descale the steam generator regularly, clean the drip tray and drain, check door seals, and inspect fan filters monthly. Always follow your manufacturer's specific guidance and use approved cleaning products. See our cleaning guide for more detail.
Do you stock spare parts? ▾
If you know the part number you need, please call us on 01227 469692 or email office@catercombi.com and we will try to help.
Can I get approved cleaning products from CaterCombi? ▾
No, we currently do not supply cleaning products, but you can order them online from different stockists.
What do I do if the oven isn't producing steam properly? ▾
First check the water line and filters, run an automatic descaling cycle if your oven has one, clean the steam outlets, and check your water supply isn't the cause. If the problem persists, log a service request (rental/warranty customers) or contact an engineer via our Find an Engineer page.
