Passenger lifts have a typical service life of 20–25 years. Modernisation is a planned capital project scoped against BS EN 81-80 (SNEL) hazard survey and delivered to BS EN 81-20/50 current safety standards. Independent specification and tender management usually pay for themselves on projects above £75,000.
When modernisation becomes the right answer
Reliability data does most of the work. If a lift is generating more than 8–10 callouts per year, if entrapments are recurring, if controller cards are being scavenged from decommissioned lifts, or if the maintainer's PPM report flags obsolete drives, the maintenance budget is being spent to defer an inevitable capital project.
The trigger point is usually one of:
- Controller obsolescence, no manufacturer support, cards end-of-life
- Drive obsolescence, motor drives no longer manufactured or supported
- Safety norm gap, EN 81-80 hazard survey identifies multiple high-priority items
- Aesthetic and accessibility upgrades, often triggered by refurbishment or Equality Act reasonable adjustment claims
Scoping under EN 81-80
BS EN 81-80 (SNEL, Safety Norm for Existing Lifts) is the hazard-scoring standard used to prioritise safety improvements on lifts predating EN 81-20/50. A SNEL survey scores hazards on a three-tier scale (high, medium, low). Modernisation scope is built around closing all high-priority hazards and as many medium ones as budget allows.
Typical high-priority hazards on 1990s and 2000s lifts:
- Lack of unintended car movement protection (UCMP)
- Insufficient safety gear stopping distance
- Landing doors without fire integrity
- Machine room fire compartmentation breaches
- Absence of ADA/accessibility-compliant controls
Partial versus full modernisation
| Controller and drive modernisation | Full replacement | |
|---|---|---|
| Scope | Controller, VVVF drive, push-button stations, safety circuits, UCMP | Everything from the pit up, new lift in the existing shaft |
| Retained | Shaft, guides, ropes, car frame, doors, architecture | Shaft only |
| On-site duration | 4 to 6 weeks per lift | 10 to 14 weeks per lift, plus lead time |
| Indicative UK cost per lift | £45,000 to £70,000 | £90,000 to £180,000 |
| Expected life extension | 15 to 20 years | 25 years or more |
| Best when | Structure and doors are sound, controls are obsolete | Multiple high-priority SNEL hazards, poor shaft condition, capacity change |
Costs are indicative ranges for planning purposes only. Building type, access, number of floors and finishes move them substantially, which is why a tendered price is the only number worth budgeting against.
Controller-and-drive modernisation replaces the brain of the lift while retaining the shaft, guides, ropes, car frame, doors and architecture. Typical scope: microprocessor controller, VVVF drive, new push-button stations, updated safety circuits, UCMP.
- On-site duration: 4–6 weeks per lift
- Typical cost (UK, 2026): £45,000–£70,000 per lift
- Payback vs escalating repair spend: 5–8 years
Full replacement installs a new lift in the existing shaft. Everything from the pit up is new.
- On-site duration: 10–14 weeks per lift (plus lead time)
- Typical cost (UK, 2026): £90,000–£180,000 per lift
- Payback vs escalating repair spend: 8–12 years
The tender route
A structured tender saves 10–25% on the final contract sum and removes lock-in to the incumbent maintainer.
- Independent survey by a lift consultant, SNEL hazard survey, condition report, options paper
- Client brief, service quality, aesthetic, accessibility, downtime tolerance
- Technical specification, controller architecture, drive type, door operator, safety systems, finishes
- Tender pack issued to three to five vetted lift companies
- Tender evaluation, price, programme, spares support, references
- Contract award using an appropriate JCT or bespoke form
During the works
Section 20 consultation (leasehold), tenant notification, temporary signage, alternative access for reduced-mobility residents, and insurer notification are all part of the pre-start checklist.
Handover
Insist on:
- EC/UKCA Declaration of Conformity under the Lifts Regulations 2016
- CE/UKCA marking on the completed installation
- Full O&M manual and as-built drawings
- 12-month defects liability period
- First LOLER thorough examination on completion, before the lift goes into service
Modernisation done well buys a further 20 years of reliability. Done badly, it locks the building into a proprietary controller with the same obsolescence problem in a decade.
How this connects to your statutory duties
Modernisation does not pause LOLER. A lift out of service for works still needs a thorough examination before it returns to use, and the first examination should be booked as part of handover rather than left to the maintenance contract. Our LOLER thorough examination guide sets out the interval and independence rules, and the LOLER versus PUWER comparison explains which regime covers what during the works.
Machine room alterations frequently breach fire compartmentation. Flag that to whoever holds your fire risk assessment, and record the fire stopping evidence in the building compliance pack.

Working with TICDesk
TICDesk is a UK procurement desk for testing, inspection and compliance work. Tell us how many lifts, their age and whether you have a SNEL survey, and we introduce up to three vetted lift companies or independent consultants, typically within 48 hours, quoting against the same specification. The service is free to the client and TICDesk earns a success fee from the contractor. Visit our lifts desk or open a brief.
Frequently asked
When should I modernise a lift?
When callout costs are rising year on year, when controller or drive spares are obsolete, when the EN 81-80 hazard survey scores 3 or more high-priority items, or when the lift is 20+ years old and reliability is dropping.
Partial or full replacement?
Partial modernisation (typically controller and drive) is cost-effective where the shaft, guides, cables and car remain serviceable. Full replacement is usually more economic where multiple systems are end-of-life or where EN 81-80 flags multiple high-priority hazards.
Do I need a lift consultant?
For projects above roughly £75,000, an independent lift consultant writes a spec that lets you tender competitively, removes single-supplier bias, and validates installation against the spec. They typically pay for themselves through tender savings.
How long does a lift modernisation take?
A single controller modernisation is 4–6 weeks on site. A full replacement in an existing shaft is 10–14 weeks per lift, plus 12–20 weeks lead time on equipment. Multi-lift phased programmes are 6–12 months end to end.
