A scaffolder designs, erects, adapts and dismantles scaffolding structures to provide safe working platforms at height. Work at height regulations require employers and the self-employed to provide appropriate access equipment - for any significant work above ground level (roof repairs, brickwork, painting, window installation) scaffolding provides the safest solution. The NASC (National Access and Scaffolding Confederation) is the primary trade body and CISRS (Construction Industry Scaffolders Record Scheme) card-holding scaffolders have demonstrated competence at the appropriate level.
What they do
- Independent tied scaffold for house exteriors
- Birdcage scaffold for flat roof and ceiling work
- Cantilever scaffold where ground anchoring is not possible
- Chimney scaffold and access platforms
- Scaffold for loft conversion dormer construction
- Temporary roofing and weather protection structures
- Highway licence management for pavement scaffolds
- Scaffold inspection and handover certificates
When you need one
Scaffolding is required for most roof and upper-storey work. Always confirm that the scaffolder will provide a handover certificate before starting work on the structure.
Typical costs (UK, 2025)
| Job type | Typical cost |
|---|---|
| Semi-detached house scaffold (erect, 2 weeks hire, dismantle) | £600 - £900 |
| Detached house 3-elevation scaffold | £1,200 - £2,000 |
| Chimney scaffold (access only) | £300 - £600 |
| Additional weekly hire charge | £50 - £100/week |
| Birdcage scaffold for flat roof | £800 - £1,500 |
| Highway/pavement licence fee | £150 - £400 |
Costs depend on the number of lifts, elevations, complexity and hire duration. Always include scaffolding in your project budget - it is typically 5-10% of total project cost for domestic work.
Qualifications to look for
NASC member companies are audited against the SG4 and TG20 technical guidance documents and must carry insurance and employ qualified scaffolders. Using an NASC member provides peace of mind on safety and quality.
CISRS cards are the recognised qualification for scaffolders. Cards are issued at Trainee, Scaffolder and Advanced Scaffolder levels, each requiring training and experience. Always check your scaffolders carry a valid CISRS card.
How to find a reputable scaffolder
Frequently asked questions
Do I need a licence to erect scaffolding on the public highway?
Yes - if scaffolding extends over or onto a public pavement or road, the scaffolding contractor must obtain a Scaffold Licence (Section 169 licence) from the Local Highway Authority. This is the contractor's responsibility, not the homeowner's. Always confirm your contractor will obtain this licence if required before work starts.
How long does scaffolding take to erect?
A standard independent tied scaffold for a typical two-storey semi-detached house usually takes half a day to one day to erect. Larger or more complex structures - such as birdcage scaffolds for flat roofs or multi-elevation wraps - take longer. The contractor will advise on timescales when pricing the job.
How much does scaffolding cost per week?
Typical costs for standard domestic scaffolding on a semi-detached house start at around £600-900 for erection, hire for 2-4 weeks and dismantling. Weekly hire charges apply after the initial period. More complex or longer scaffolds such as those needed for full roof replacement or chimney work cost proportionally more.
