Capital Repairs has been fixing household appliances across London since 1983 with over 40 years of hands-on experience with microwaves from every major manufacturer.
In that time, our engineers have completed thousands of repairs, from simple fuse replacements to full magnetron swaps.
Every repair is covered by our workmanship guarantee, and every engineer is fully insured, so you’re protected from the moment they arrive. We use genuine or high-quality manufacturer-approved replacement parts, never cut corners, and our engineers carry a wide range of parts on the van to fix most faults on the first visit.
Pricing is transparent from the outset: a one-off call-out and labour charge with no hidden extras, and repairs starting from £85. Before any work begins, we’ll diagnose the fault and give you a clear quotation, so you know exactly what you’re paying for. Repair is usually more cost-effective than replacement.
We’re proud of our reputation. Our Google and Trust Pilot reviews consistently highlight engineers who turn up on time, explain the problem clearly, and fix it right first time. It’s why so many London households call us again the next time an appliance breaks down.


Microwaves fail for all sorts of reasons, and our engineers see, and fix, nearly every one of them.
Whatever the fault, our engineers will carry out a full diagnosis before recommending a repair, so you always know what’s wrong before we start work.


We repair microwaves from every major manufacturer, including Bosch, Samsung, Panasonic, Neff, Siemens, Miele, Hotpoint, Whirlpool, Sharp, LG, Beko and AEG.
Each manufacturer builds its microwaves a little differently, from the layout of the control board to the way the door interlock switch is fitted, so our engineers keep up to date with the specific quirks of every brand. If you don’t see your make listed, get in touch – the chances are we’ve fixed one just like it before.
Not every microwave is installed the same way, and our engineers are experienced across the full range:
Built-in microwaves: fitted into kitchen cabinetry, including safe removal and refitting where access is tight
Freestanding microwaves: standard countertop models
Combination microwave ovens: combi units with grill or convection functions, which have more components to diagnose
Integrated microwaves: built seamlessly into your kitchen units
Microwave grills: models with an added grill element, prone to their own specific faults
Whatever type you have, and wherever it’s installed in your kitchen, we have the tools and experience to repair it in place.
We can repair:
