If you need a certified UK event power supplier and kes.co.uk is not the right fit, the strongest alternatives are Jaks Party Power Limited, alongside specialist firms such as Pearce Hire and Raiden Electric, all of which operate under BS 7909:2023+A1:2024 and BS 7671 compliance frameworks. The non-negotiable baseline for any credible supplier is a full site survey, certified equipment, and a formal Test and Inspection Certificate issued after installation. Without that certificate, your event insurance may be invalid.

What should you look for in a kes.co.uk alternative?
Choosing a replacement supplier is not simply about finding someone with a generator to hire. UK event organisers carry a legal duty under the Electricity at Work Regulations 1989 to ensure all temporary electrical installations are properly selected, installed, and maintained. That duty sits with you, not just the contractor.
The practical checklist for vetting any supplier:
- Confirmation they work to BS 7909:2023+A1:2024 and BS 7671:2018+A2:2022
- A written site survey and load schedule before any equipment is specified
- 30mA RCD protection on all outdoor and temporary circuits, per Regulation 411.3.3
- IP-rated distribution boards and PAT-tested appliances
- TT earthing for outdoor temporary supplies unless PME bonding is verified
- Public liability insurance and a formal Test and Inspection Certificate on completion
- Risk assessments and method statements (RAMS) provided before the event
- Standby personnel available on-site during the event
Pro Tip: Generators should be sized at least twice the peak calculated load. Motor start surges and harmonic distortion from lighting rigs can trip an undersized generator mid-event, and there is rarely a quick fix once the crowd is in.
Powerful Thinking, the industry sustainability body, advises organisers to look beyond the hire cost and ask suppliers directly about fuel efficiency, hybrid generator options, and whether they can reduce the total number of generators through smarter load consolidation. A supplier who cannot answer those questions in 2026 is behind the curve.
Compliance callout: All outdoor and temporary supplies must carry 30mA RCD protection as a minimum under BS 7671 Regulation 411.3.3. Non-compliant setups risk invalidating event insurance.
How do UK event power suppliers compare on services and compliance?
The table in the opening section covers the headline differences. What it cannot show is where suppliers diverge on the details that actually affect your event day.
Pearce Hire built its reputation on large-scale festival work, with documented fuel management programmes developed in partnership with Powerful Thinking. That depth of fuel monitoring suits touring productions and multi-stage festivals where generator running costs are a meaningful budget line. For a wedding or a corporate dinner in the South East, that level of infrastructure is often more than you need.
Raiden Electric takes a full turnkey approach to outdoor events: site survey, power plan, supply, installation, and on-site support in one package. They issue a formal test certificate and carry public liability insurance as standard. Their published guidance is among the clearest available on cable routing, IP-rated connectors, and why domestic extension leads are never acceptable for outdoor event runs.
Jaks Party Power Limited covers the same full-service model with the added weight of over 40 years of electrical contracting behind it. The hire catalogue spans generators, distribution boards, lighting, and cables, with on-site standby support often included. For event organisers in Sussex and the surrounding area who want one point of contact from site survey to sign-off, that breadth is the practical differentiator.
How do pricing models differ among event power suppliers?
Pricing in the UK event power sector is rarely published as a flat rate. Most credible suppliers quote per-event after a site survey, because load requirements, cable runs, access constraints, and event duration all affect the final figure. That said, the structure of what you pay for tends to follow a consistent pattern across the market.
Most suppliers price on a combination of equipment hire, delivery and collection, installation labour, and a day rate for on-site standby personnel. Fuel is usually charged separately, either at cost or against an agreed consumption estimate. Fixed-fee contracts, where the supplier absorbs fuel cost risk, are available from some larger operators and suit organisers who want budget certainty. Jaks Party Power offers hire packages covering generators, distribution, and lighting, with pricing available on request through their hire page.
The Powerful Thinking guidance is direct on one point: focusing only on the day-rate hire cost is a false economy. A supplier who helps you right-size generators, consolidate loads, and reduce running hours will often deliver a lower total cost than a cheaper quote that leaves you running oversized plant all weekend.
What does the hiring process look like, and how long does it take?
Most reputable UK event power suppliers follow a broadly similar sequence, though timelines vary by event scale.
For a straightforward outdoor event, the process typically runs as follows. First contact and brief, usually a few weeks before the event for smaller jobs, longer for festivals or complex multi-stage builds. The supplier then conducts a site survey, either in person or via detailed plans, and produces a written load schedule. Equipment is specified, a quote issued, and once agreed, RAMS are prepared. Delivery and installation happen in the day or two before the event, with testing and certification completed before any public access. On-site standby covers the event itself, and de-rig follows immediately after.
For larger productions, lead times of several weeks to a few months are common, particularly where bespoke cable runs, multiple generator sets, or temporary substation connections are involved. Booking early also gives you leverage on generator sizing: a supplier with time to plan will right-size the plant, whereas a last-minute booking often means taking whatever is available. The corporate event generator hire process guide covers the full sequence in detail for those planning more complex builds.
