Museum Cleaning Services (London): What Facilities Managers and Trustees Should Look For

We are so lucky to work with so many incredible places in London and the UK.

And what we can recommend: choosing museum cleaning services in London isn’t the same as appointing a general commercial cleaner. Museums, galleries, archives and cultural sites balance three things every day: visitor experience, building presentation, and collection protection.

If you’re a procurement manager, facilities manager, or trustee preparing to appoint (or re-tender) a cleaning contract, this guide provides a practical checklist to reduce risk, protect collections, and secure consistent standards from day one.

Why specialist museum cleaning matters (and why “standard cleaning” can be risky)

Museums contain sensitive environments and materials: historic interiors, conservation-grade display cases, controlled humidity zones, and collections that can be damaged by the wrong chemicals or abrasive methods.

Collections care guidance commonly emphasises environments free of dust and pollutants, as particulate contamination and airborne pollutants can contribute to deterioration over time.

In museum housekeeping plans and conservation policies, it’s also common to restrict products: polishes, cleaning agents or sprays may be prohibited in collection areas unless approved by a conservator, because residues, VOCs and overspray can pose risks.

Procurement takeaway: your cleaning contractor must understand the difference between:

• cleaning public / back-of-house building areas, and

• cleaning collection-adjacent environments (where methods, products, access, and supervision may change).

  
  

What “conservation-safe cleaning” should mean in your contract

You’ll see the terms conservation, safe cleaning, and museum conservation cleaning used often. In procurement terms, they should translate into clear, auditable controls such as:

1) Approved products + documented COSHH

• A defined list of approved chemicals (and where they may be used).

• No sprays/aerosols near collection areas unless explicitly authorised.

• COSHH, dilution control, and storage/transport procedures.

This aligns with common museum housekeeping approaches that restrict polishes and cleaning agents without conservator oversight.

2) Tooling designed to minimise dust and residue

• HEPA-filter vacuums (particularly for dust management).

• Microfibre systems with controlled laundering.

• Colour-coded cloths/mops to prevent cross-contamination (e.g., toilets vs gallery edges).

Even in heritage storage cleaning studies, methods often avoid introducing unnecessary moisture/chemicals in collection contexts and focus on controlled dust removal techniques.

3) Defined boundaries: what cleaners do not do

Your contract should state clearly:

• Cleaners do not clean accessioned objects or conservation-sensitive surfaces unless specifically trained/authorised and supervised.

• Display case cleaning is limited to glass/external surfaces unless instructed otherwise by collections staff.

(Your method statement should mirror museum practice, where object cleaning is restricted to trained personnel.

Procurement checklist: what to require in a museum cleaning tender

Use this as your tender or ITT checklist for specialist museum cleaning and cultural site cleaning.

A) Compliance and assurance (minimum pack)

Ask bidders to supply:

• Public liability + employer’s liability insurance (confirm limits)

• RAMS (risk assessments + method statements) per zone type (galleries, stores, offices, events)

• COSHH file + product list (with “museum-safe” notes)

• Training matrix (site induction, manual handling, working at height, lone working, key holding, alarm protocols)

• Quality plan (audits, supervision, escalation)

• Business continuity (holiday/sickness cover, emergency response)

B) Security, vetting, and discretion (non-negotiable in museums)

For secure museum cleaning and discreet cleaning services, specify:

• Identity checks, right-to-work checks, references

• DBS level appropriate to your site risk profile (state your requirement)

• Access control: keys, alarm codes, restricted zones, sign-in/out

• No unauthorised photos / social media

• Clear rules for interaction with visitors and staff

C) Conservation and collections risk controls

Require evidence of:

• “Conservation-safe” approach (products, tools, zone rules)

• How they prevent cross-contamination (equipment zoning, colour coding)

• Spill response approach (including who is authorised to respond in collection-adjacent areas)

• Liaison process with curators/conservators for approvals and exceptions

D) Building fabric and heritage sensitivity (listed / historic sites)

If your museum is in a historic building, include:

• Experience with heritage cleaning services UK and cleaning historic buildings

• Surface-specific approach (stone, timber, lime plaster, historic metals)

• Proof they won’t “solve” marks with aggressive chemicals or abrasives

E) Visitor experience and operational flow

Museums have peaks, quiet zones, school groups, evening events, and changing exhibitions. The winning contractor should show:

• Cleaning schedules aligned to visitor flow

• Quiet cleaning methods during open hours (where needed)

• Out-of-hours plan for galleries and high-profile spaces

• Fast turnarounds for toilets, entrances, cafés, and shop areas

  
  

Gallery and exhibition cleaning: what to specify

For gallery cleaning services and exhibition space cleaning, your spec should separate tasks into zones:

Front-of-house daily priorities

• Entrances, mats, and tracked-in dirt control

• Toilets, touchpoints, and bins

• Floors appropriate to finish (no over-wetting; correct pads/chemistry)

• Glass barriers, fingerprints on rails, and signage cleaning

Gallery/exhibition priorities

• Streak-free glass (cases/barriers) using approved methods

• Care around plinths, labels, and floor-level exhibits

• Dust management routines that minimise airborne redistribution

Back-of-house

• Workshop areas, loading bays, staff kitchens

• Waste movement routes that avoid gallery contamination

  
  

Pricing: how museum cleaning is typically costed (London reality check)

Museum cleaning pricing depends heavily on security and specialist requirements (access control, out-of-hours work, specialist materials care, and exhibition changeovers).

As a baseline, general UK office cleaning is often quoted at £20 – 25 per hour per cleaner, with higher rates for specialist/one-off work. London market averages reported by commercial providers often sit higher (for office contexts), commonly £20,50–£30 per hour.

Procurement tip: for museums, don’t compare suppliers on hourly rate alone.

Compare:

• What’s included (supervision, consumables, audits, cover, specialist tooling)

• Zone restrictions and “do not do” boundaries

• Response times for incidents and events

• 
  

Tender questions that quickly reveal who is “museum-ready”

You can lift these into your ITT:

1. What products are prohibited in gallery/store areas, and how is compliance enforced?

2. Explain your conservation-safe cleaning approach and who signs it off on-site.

3. How do you manage dust without redistributing it into the air?

4. How do you handle emergency spills near exhibits or display cases—who has authority?

5. What vetting do you apply to staff working in restricted-access zones?

6. How do you clean around exhibition changeovers and late-night events?

7. Show an example QA report (audit scoring + corrective actions).

8. What is your mobilisation plan for the first 30 days (training, zoning, standards, handover)?

   
   

A simple evaluation scorecard (procurement-ready)

Weighting suggestion for a museum:

• 30% Conservation/collections risk controls

• 20% Security, vetting, discretion

• 20% Quality assurance + supervision

• 15% Operational fit (hours, events, flexibility)

• 15% Price and contract transparency

Final thoughts

The best museum cleaning services UK providers reduce risk through clarity: approved methods, controlled products, trained people, strong supervision, and security discipline, while still delivering a calm, visitor-ready environment every day.

If you’re appointing specialist museum cleaning in London, build your tender around conservation and security first, then evaluate service management and value, not just the headline price.

Next step: book a site survey and ask for a written mobilisation plan (first 30 days), zoning map, and QA sample report, so you can compare suppliers on evidence, not promises.
