What we do and who it is for
Variable frequency drive (VFD) supply, installation, replacement and investigation for Canterbury businesses — fixed written prices provided before work begins. Based at Fruitworks Coworking, we serve Canterbury (CT1), Harbledown, Rough Common, Wincheap, St Dunstan's and Thanington. Work is certified to applicable electrical and manufacturer standards and backed by a 12-month workmanship guarantee.
Typical jobs
We carry out VFD work across Norwich and its surrounding neighbourhoods, tailoring every job to the local properties and typical installations we encounter there. In Norwich city centre and the Georgian terraces of Heigham, we replace failed drives on pumps and extraction systems in Victorian and early-20th-century domestic conversions and small terraced shop premises; in the newer housing estates of Thorpe St Andrew and Taverham we commonly service pumps and fans in semi-detached and detached homes built in the 1960s–1990s; and in the industrial estates at Rackheath and Bowthorpe we replace and upgrade drives on conveyors and process equipment in light-industrial units and 1970s factory buildings.
Before committing to work in any Norwich location we assess the existing installation on-site so your motor control remains suitable for the duty and environment specific to that property. For a Victorian terraced house in Unthank or a post-war council house in Mile Cross we verify the local supply, isolators, earthing and protective devices appropriate to the age and wiring practice of that property.
When inspecting motors in Norwich properties we check insulation, connections, loading and rotation with reference to the wiring arrangements typical of that neighbourhood: older brick terraces often have re-wired fused spur arrangements, whereas 1980s houses in Sprowston and Hellesdon usually have modern consumer units. In commercial and industrial addresses such as Bowthorpe or the Riverside Industrial Area we review three‑phase motor loading and supply balance. After installation or repair at a specific Norwich address we test operation safely and in a way appropriate to that site’s access, plant layout and local distribution.
We record and document settings and test results for the specific Norwich property so you have a record tied to that particular address and installation.
What it costs
We quote VFD and inverter-drive jobs in Canterbury after a free survey so we can specify the correct drive, motor rating, control method and installation environment. Installation and maintenance costs are provided per job with a fixed written price before work starts.
| Job | Price | What's included |
|---|---|---|
| VFD installation | Quoted per job | Parts, labour, testing, certification, VAT |
| Fault finding | £80/hr | Diagnosis; most faults traced in 1–2 hours |
| Emergency attendance | £120/hr | Out-of-hours labour; first hour minimum |
Not included: plaster or decoration, asbestos removal, DNO supply-upgrade charges, scaffold or specialist access equipment.
How the work is planned
Before we specify a VFD or inverter drive, we survey the motor, driven equipment, supply, control requirements and installation environment. We confirm motor ratings, load profile, starting duty, cable routes, isolation points, ventilation, harmonic considerations and any interface with existing controls. This establishes a workable scope without disrupting critical operations.
We then agree Project phasing around your production, occupancy or service requirements. Where shutdowns are necessary, we define their duration, sequence and access arrangements in advance. Resource scheduling allocates suitably competent electricians, commissioning time and any specialist support to the agreed programme.
Before installation, we prepare the work area, identify containment and cable routes, and coordinate isolations with your responsible person. We install, configure and test in controlled stages, checking rotation, speed limits, protective settings and process response before returning equipment to normal operation.
Compliance and documentation
Although VFD and inverter-drive installations vary by application, we document the design, installation, settings, protective measures and commissioning results so the system can be safely operated and maintained. Our records support document control, including circuit details, drive parameters, manufacturer information, test results and operating instructions. We complete a risk assessment addressing isolation, fault protection, earthing, electromagnetic compatibility and foreseeable maintenance activity. Asset tagging links each drive to its records, helping your responsible person identify equipment, settings and inspection history quickly.
Contrary to a common belief, there is no statutory fixed interval for EICRs for commercial fixed wiring set out in primary legislation. The Electricity at Work Regulations 1989 require that electrical systems be maintained so as to prevent danger; they do not prescribe a specific inspection period. We can provide recommended inspection intervals based on IET Guidance Note 3, the environment, equipment condition, duty cycle and assessed risk. Insurers, landlords or licensing bodies may require a current report in individual cases, but that is a contractual or policy condition rather than a universal legal obligation.
Minimal disruption and out-of-hours working
Careful planning and clear records also help us minimise disruption when installing or maintaining VFDs and inverter drives. Before attendance, we agree the scope, isolation points, permits, programme and testing sequence with you. Effective client liaison lets us identify critical equipment, operational constraints and acceptable shutdown windows.
Our access planning covers delivery routes, plant-room entry, parking, keyholding arrangements and safe segregation from occupants or staff. We schedule intrusive work out of hours where this best protects normal operations, with costs and attendance times confirmed in writing.
We apply proportionate noise mitigation, including controlled drilling periods, suitable tools and advance notice where noise cannot be avoided. On completion, we remove waste, reinstate access routes and provide commissioning records. If unexpected conditions arise, we’ll stop, assess the risk and agree the next steps before proceeding.
Premises and sites around Canterbury
Before work starts at any Canterbury address we confirm the scope, price and shutdown requirements in writing referencing the named property and neighbourhood, then provide the appropriate test results and completion documentation tied to that specific site.
The property mix in Canterbury — Georgian brick houses near the cathedral precincts, Victorian terraces in Wincheap and St Dunstan's, large student rental stock, new estates at the edges — means no two jobs are alike. Our electricians spend much of their time on student and rental HMO compliance, listed and period property in the precincts, commercial work for the city centre, and we plan each visit around the age of the wiring rather than a one-size-fits-all checklist.
