Living at home during the works

Yes, provided the job is phased and one habitable zone with a working bathroom is kept alive throughout. It is not advisable during a full renovation that replaces all the installations: water and power go down across the whole flat for stretches of weeks, and dust reaches everywhere regardless of protection. Two bathrooms make staying home genuinely comfortable — one is renovated while the other keeps working; with a single bathroom that phase needs a very short agreed timescale and a plan B for showers. The trade-off is money and time: phasing repeats protection, crew mobilisation and cleaning at every stage, adding roughly 10–15% to the cost and several weeks to the total.

Yes — if the work is phased and one habitable zone with a working bathroom always remains. It is not advisable during a full renovation with complete replacement of installations: weeks without water, intermittent power and dust everywhere make it very hard.

When phasing makes sense

• There is no alternative accommodation, or temporary rent would eat the budget
• The work splits into separable zones: bathrooms first, then kitchen, then bedrooms
• You prefer to spread the payments over time
• There are two bathrooms: one is renovated while the other keeps working

When it does NOT make sense

When all installations are being replaced: water and power cuts affect the whole flat at once, and splitting the job multiplies both the total time and the fixed cost of every crew entry and exit. If you live abroad and the flat is empty — always do it in one go.
