The short answer
If the building was put up before 2000, plan for one. A refurbishment and demolition survey checks the parts of the toilet block that will be disturbed, including ducts, floor tiles, boxing and ceilings, which the routine management survey may not reach. Commission it before the contractor prices the job, because what it finds changes the cost and the programme.

Toilet blocks in older schools are some of the places asbestos is most likely to turn up during a refurbishment. Ducts, boxing, floor tiles and old cisterns were all made with it at one time, and stripping out a washroom disturbs exactly those things. Finding it in week one of a six-week summer programme can wreck the timetable.
Two kinds of survey
Most schools already have an asbestos register built from a management survey. That survey is for day-to-day occupation: it finds materials that could be damaged in normal use, and it usually avoids intrusive work such as lifting floors or opening sealed boxing.
A refurbishment and demolition survey is different. It is for areas that will be disturbed by building work. It is fully intrusive within the area concerned and is designed to find everything the work will touch. HSE’s guidance on asbestos surveys explains the difference and says the area should normally be vacated for the survey.
For a toilet refurbishment, the survey covers the rooms being stripped and any routes for new drainage, ventilation or cables.
When you need one
If the school building was constructed before 2000 and you plan to strip out a toilet block, assume you need a refurbishment and demolition survey of that area. The school or its responsible body, as duty holder, should arrange it, and the contractor relies on it to plan the work safely.
The government’s guidance on managing asbestos in schools is aimed at responsible bodies, school leaders and governors, and points to HSE resources on the duty to manage.
Where asbestos hides in school washrooms
Common places in older toilet blocks include:
- vinyl floor tiles and the adhesive beneath them
- boxing and duct panels around pipes and cisterns
- old high-level cisterns and toilet seats
- textured coatings on walls and ceilings
- ceiling tiles and the insulation above them
- pipe lagging in ducts and risers
- window boards and panels near basins
Only a survey can confirm what is there. Do not let anyone drill, lift or break these materials until you know.
How it affects cost and time
What the survey finds shapes the job:
- Nothing found. The refit proceeds as planned.
- Low-risk materials. Some can be removed by trained operatives within the main programme.
- Licensed work. Some materials need a licensed contractor, with notice periods before work starts and air testing afterwards. That adds cost and needs time at the start of the holiday.
Council contracts show this is normal, not exceptional. Wigan’s 2025 award for phase 2 of a primary school toilet refurbishment listed asbestos removal alongside new cubicles, sanitaryware, flooring and ceilings in a contract of about £79,000. Our cost planner treats asbestos removal as part of the full strip-out band for that reason.
When to commission it
Order the survey early in the planning year, ideally in the spring term before a summer refurbishment:
- It needs access to the empty rooms, which may mean a half-term or weekend.
- Results feed into the specification and the contractors’ prices.
- If licensed removal is needed, the notice period and removal can be planned into the first week of the holiday.
- If you are making a CIF bid, survey findings are strong evidence.
What to give your contractor
Share the asbestos register, the refurbishment and demolition survey report with its drawings, and any previous removal records. Ask contractors to state in their quotes how they have allowed for the findings and what happens if something unexpected turns up. Under CDM 2015 the school, as client, must provide this kind of pre-construction information. See our guide to tendering school toilet works.
The short version
For any school toilet refurbishment in a building from before 2000, commission a refurbishment and demolition survey of the area before contractors price the job. It finds what the routine survey cannot, it protects pupils and workers, and it stops a summer programme falling apart in week one.
