Welfare and site set-up on domestic jobs

On commercial sites, welfare and set-up have their own budget line and nobody blinks. On domestic jobs, the same costs exist but hide inside "we'll sort it when we get there", which means they get paid out of margin instead of out of the quote. Here is what set-up really involves, and how to price it without apology.

The obligations do not shrink because the job is a house

Construction health and safety law, including the CDM regulations, applies to domestic projects. The client's duties usually pass to the contractor, which means the contractor, you, carries responsibility for a safe, managed site with suitable welfare arrangements: somewhere to wash hands, access to a toilet, somewhere to eat and get warm, drinking water, first aid. On a small job some of this is sensibly agreed with the homeowner, such as use of an existing toilet. On a bigger job, or one where the house is uninhabitable mid-works, it means hired facilities. Either way it is a decision to make and, where money is involved, a line to price, not an improvisation for week one.

What set-up actually includes

Walk a job mentally from the day before start, and the set-up list writes itself:

• Welfare: toilet hire, or agreed indoor arrangements; a dry mess area; water and power for the kettle that runs the site.
• Protection: floor protection through the house, dust screens and zipped doorways, carpet film, covering the client's garden, protecting the drive from the grab lorry.
• Security and separation: Heras panels or hoarding where the garden is open, lockable storage for tools and materials, keeping children and pets out of the work area.
• Temporary services: a safe temporary electrical supply, task lighting, sometimes temporary water or drainage bypasses while services are moved.
• Signage and neighbours: a contact board, and the ten minutes of neighbour diplomacy that saves ten complaints.
• Set-up and strike labour: the day at the start and the half-day at the end that nobody prices because it is not "real work". It is real work.

Fixed lines and time-related lines behave differently

The estimating subtlety is that set-up splits into two kinds of cost. Fixed costs happen once regardless of programme: erecting the fence, laying protection, wiring the temporary supply, the strike at the end. Time-related costs run weekly: the toilet hire, the fence rental, the storage container. When the programme stretches, only the second group grows, so a quote that lumps everything into one number cannot respond honestly when the client asks what a delay costs, and cannot protect you when the delay is theirs.

Price them as two visible groups. It takes one extra minute and it plugs one of the classic leaks described in preliminaries explained: the site costs most builders under-price. The weekly group also gives you the honest arithmetic for extensions of time, which connects directly to how programme length quietly changes your price.

Scale it to the job, do not delete it

The objection writes itself: "I cannot put a welfare unit on a two-week bathroom job." Correct, and nobody is asking you to. Proportionality is the principle: the obligations scale with the size and risk of the work, and so should the money. On a small occupied job, welfare might genuinely be an agreement to use the family bathroom and a sheet of protection on the landing, costing thirty pounds and a conversation. On a three-month extension with the kitchen out of action, it is a hired toilet, a dry store and a proper protection package. The estimating failure is not choosing the small answer, it is choosing no answer: pricing every job as if set-up were free and then discovering, four jobs a year, that it was not. Decide the appropriate level per job, price that level, and write one line even when the line is small.

Presenting it without a fight

Builders sometimes hide set-up costs because they fear the client will see them as padding. The opposite is true when they are presented properly. "Protection of your home and garden: 380" is one of the most reassuring lines a homeowner can read, because it says you have thought about their carpet before your first invoice. Welfare, protection and security lines signal a professional operation, and professional operations win better clients at better margins. The same logic applies across the whole document, which is why presentation itself is a price signal, as argued in win more of the quotes you send.

Make it a checklist, then make it automatic

Set-up costs are the most repeatable section of any quote. The same dozen lines appear on every domestic job, scaled by duration and occupancy. That makes them the perfect candidate for systemisation: a standard checklist priced at your local rates, adjusted per job, never forgotten at 9pm on quote night. This is precisely how QS Quoter treats them: generate a quote from a description or drawings and the set-up and welfare lines arrive itemised at your rates, editable line by line, with a clean client copy and a private cost copy that shows you where the money sits. The jobs where you remember the toilet hire and the jobs where you forget it should not be decided by how tired you were.
