Workplaces ready for people

For offices and business premises that need cleaning to fit around opening hours.
We clean Monday to Saturday, 5am–10pm, by arrangement. We quote after a free site visit. You get a named contact, regular quality checks, and colour-coded cloths so toilet cloths never touch kitchens.
GASI brings all the equipment and products. Prefer us to use yours? Just tell us when you ask for a quote. Toilet roll, soap, hand towels and bin bags come from your own supplies, and we restock them.
Contracts can be ended by either side with 30 days’ written notice.
The price is per cleaner hour: £25 for one-off or weekly cleans, £23 for 2 or more visits a week. The quote form gives an estimate from your floor area, washrooms and kitchens, and we confirm it after the site visit.
Business clients receive an invoice by email, payable within 14 days by bank transfer. Regular contracts are invoiced monthly.

How the estimate works
