Located at 45 Richmond Avenue in North London, Hihisu operates as a full-service garage handling routine maintenance and complex repairs. Our facility covers 850 square metres and contains eight service bays equipped with Bosch diagnostic systems and Hunter alignment equipment.
We service all makes and models, from compact city cars to commercial vans. Our team consists of nine technicians, each holding Level 3 qualifications from the Institute of the Motor Industry. Three specialists focus on diesel engines, two work primarily with hybrid systems, and four handle general repairs. This structure allows us to assign work based on actual expertise rather than availability.
The workshop uses OEM parts for warranty work and approved aftermarket components for older vehicles. We maintain direct accounts with Bosch, Mann+Hummel, and Sachs, ensuring parts arrive within 24 hours for most repairs. For less common models, we work with Euro Car Parts and their network of suppliers across the UK.
Our diagnostic process begins with a digital inspection using Bosch KTS systems, which connect to manufacturer databases for accurate fault code reading. This approach reduces guesswork and prevents unnecessary part replacement. After diagnosis, technicians provide a written estimate showing labour hours, parts costs, and VAT before starting any work.
Services range from MOT testing and brake replacement to timing belt changes and clutch repairs. We also handle air conditioning recharging, suspension work, and electrical diagnostics. For fleet operators, we offer scheduled maintenance contracts with priority booking and detailed service records.
The waiting area includes WiFi, coffee facilities, and a small workspace for those who need to work during service appointments. For longer jobs, we can arrange courtesy cars through our partnership with a local rental company, subject to availability and insurance requirements.

Find answers to common questions about our garage services, maintenance schedules, and repair procedures
Standard service intervals depend on your vehicle manufacturer's recommendations, typically ranging from 10,000 to 15,000 miles or annually. However, driving conditions significantly impact this schedule. City driving with frequent stops, short journeys under 10 miles, or towing heavy loads require more frequent attention.
We recommend checking your owner's manual for specific intervals. Our technicians can also assess your driving patterns and suggest a tailored maintenance schedule. Regular servicing prevents costly repairs, maintains fuel efficiency, and ensures your vehicle remains reliable and safe on London roads.
Our standard service includes engine oil and filter replacement using manufacturer-approved lubricants, comprehensive fluid level checks including coolant, brake fluid, and power steering fluid. We inspect brake pads and discs for wear, examine tyres for tread depth and damage, and test all lights and indicators.
Additionally, we check the battery condition, inspect suspension components, examine the exhaust system for leaks or corrosion, and assess wiper blades. Each service concludes with a detailed report highlighting any areas requiring attention. We use genuine or OEM-equivalent parts and follow manufacturer specifications throughout the process.
We offer courtesy vehicles for customers requiring extended repairs, subject to availability and advance booking. These vehicles are provided free of charge for work exceeding four hours. Drivers must be aged 25 or over, hold a full UK driving licence for at least two years, and provide proof of address.
For shorter services, our waiting area offers comfortable seating, complimentary refreshments, and WiFi access. We're located near Richmond Avenue with excellent public transport links, and our team can advise on local bus routes and Underground connections if needed. Please mention your transport requirements when booking to ensure we can accommodate your needs.
A standard MOT test takes approximately 45 to 60 minutes to complete. This timeframe covers all mandatory checks including lights, brakes, steering, suspension, tyres, exhaust emissions, and body condition. We conduct tests using calibrated equipment that meets DVSA standards.
If your vehicle requires remedial work following the test, repair time varies depending on the issues identified. Minor adjustments like bulb replacements or wiper blade changes can be completed immediately. More substantial repairs are quoted separately, and we'll discuss options and timescales before proceeding. We recommend booking your MOT at least two weeks before expiry to allow time for any necessary repairs.
We utilise manufacturer-level diagnostic systems compatible with all major vehicle brands including European, Japanese, and American models. Our equipment reads fault codes from engine management systems, ABS, airbags, transmission, and other electronic control units. This technology provides real-time data on sensor readings, enabling accurate fault identification.
Beyond code reading, our diagnostics include live data analysis, component activation tests, and system recalibration. Our technicians hold certifications in diagnostic procedures and regularly update their knowledge as vehicle technology evolves. This investment in equipment and training ensures we can service modern vehicles with complex electronic systems efficiently and accurately.
No, servicing with us will not invalidate your manufacturer's warranty. EU Block Exemption Regulation allows vehicle owners to have their cars serviced at independent garages while maintaining warranty coverage, provided the work meets manufacturer standards.
We use parts that meet or exceed OEM specifications, follow manufacturer service schedules precisely, and maintain detailed service records. All work is documented with invoices showing parts used and procedures completed. This documentation satisfies warranty requirements. Our technicians are trained to manufacturer standards, and we stay current with technical service bulletins. Many customers choose us for warranty-period servicing due to our competitive pricing without compromising quality or warranty protection.
We accept multiple payment methods for your convenience: cash, all major debit and credit cards including Visa, Mastercard, and American Express. Bank transfers are available for larger invoices, and we can provide account details upon request.
For unexpected repairs, we offer flexible payment arrangements. Detailed invoices are provided showing labour hours, parts costs, and VAT breakdown. We can email invoices for business customers requiring documentation for accounting purposes. Payment is due upon collection of your vehicle unless alternative arrangements have been agreed in advance. We do not currently accept cheques.
