What we do and who it is for
We replace faulty or unsupported solar inverters with certified replacements — fixed written prices cover equipment, labour and required electrical certification. Serving Whitstable and nearby areas including Tankerton, Seasalter, Swalecliffe, Joy Lane and Church Street. Work is guaranteed with manufacturer-backed warranties and NICEIC/Electrical Safety Certificate issued on completion.
Typical jobs
We typically carry out inverter work across Worthing and its surrounding neighbourhoods, so the way we approach jobs in places like Heene, Goring-by-Sea, Tarring and West Durrington is tailored to the local housing stock and road layouts.
Typical solar inverter jobs in Worthing include swapping failed string inverters in 1930s semi‑detached houses in Salvington, replacing obsolete units in 1960s council terraces in West Durrington where manufacturer monitoring or spares are no longer available, and upgrading undersized equipment after array extensions on Victorian end‑of‑terrace properties in Broadwater.
- For battery retrofits in areas such as Goring and Tarring where many homes are 1960s/70s stock we confirm export controls, check the existing cable capacity in the property’s cellar or garage, and assess whether a hybrid inverter suits the specific layout and consumer unit of that house.
What it costs
Costs for solar inverter replacement in Whitstable are quoted per job after a free survey because the final scope depends on inverter type, access and the condition of existing wiring and components. We provide fixed replacement costs in writing including VAT, parts, labour, testing and certification so your bill won’t exceed the quote.
| Job | Price | What's included |
|---|---|---|
| Inverter replacement | Quoted per job | Parts, labour, testing, certificate, VAT |
| Fault finding | £80/hr | Electrical diagnostics |
| Emergency attendance | £120/hr | First hour minimum |
Not included: scaffold/specialist access equipment, plaster repairs, decoration, asbestos removal, DNO supply-upgrade charges; any remedial array-fault work will be priced separately.
How the work is planned
Once we’ve confirmed the fixed price, we’ll survey the existing inverter, isolators, consumer-unit connection and generation meter arrangement before ordering a compatible replacement. We’ll check mounting space, cable routes, ventilation, communications requirements and whether the new unit can use the present DC strings without unnecessary alterations.
Our scheduling logistics account for delivery lead times, daylight working conditions and the need to minimise generation downtime. We’ll agree access coordination in advance, including clear access to the inverter location, consumer unit and any loft or external isolators. Please keep pets away from work areas and avoid using affected circuits during the changeover.
On the day, we’ll isolate AC and DC supplies safely, remove the failed or outdated inverter, fit and connect the replacement, then test operation before restoring the installation.
Compliance and documentation
For a solar inverter replacement in Whitstable, we’ll provide the relevant electrical certification and commissioning records, confirm safe isolation and test the AC connection before handover. Certificate issuance will follow completion of the work, with results recorded for the inverter supply, protective devices, earthing and functional operation. We’ll also explain which documents you should retain for warranties, insurers, future maintenance and any property sale.
Keeping records helps show the system has been maintained and that any alterations were properly tested; this is important evidence but is not in itself a statutory guarantee of safety. For commercial premises there is no single statutory interval for fixed‑wire EICRs; while the IET Guidance Note 3 recommends typical intervals (for example, five years for offices, three years for some industrial sites and annual checks for higher‑risk environments), these are guidance rather than legal requirements — the legal duty is simply to maintain electrical systems so as to prevent danger. We’ll quote any certification costs clearly before work begins.
Minimal disruption and out-of-hours working
With the documentation in hand, we’ll plan your solar inverter replacement to keep downtime and disruption to a minimum. We’ll agree isolation times, access arrangements and a fixed written price before work starts, so you can schedule around generation losses and occupancy.
Where practical, we can prepare mounting, containment and settings before the changeover, then isolate the AC and DC supplies safely, replace the unit, test protective functions and recommission it efficiently. Evening access may suit premises that need daytime continuity, subject to safe lighting, manufacturer requirements and our out-of-hours rate of £120 per hour. Noise control matters too: we’ll limit drilling, use appropriate dust containment and avoid unnecessary running of tools. We won’t energise the system until polarity, insulation resistance, earthing and operational checks are satisfactory.
Premises and sites around Whitstable
At historic mill buildings such as the former paper mills at Church Street and at listed structures within the town centre conservation area we design cable routes and work methods to minimise alteration to the original fabric of those particular buildings.
For every job we’ll provide a fixed written price for the Whitstable property in question that covers labour, parts and the required certification for that specific address, so residents and businesses in those neighbourhoods can compare replacement costs for their individual premises without unexpected additions.
