A bathroom renovation involves several trades at once: tilers, plumbers, electricians and fitters. In the UK two of them come with rules of their own — electrical work in bathroom zones is notifiable under the building regulations (Part P), and waterproofing is what separates a ten-year bathroom from a two-year one. A quote that sets all of this out clearly is rare, and that's exactly where the risks live. We check your bathroom quote and give you concrete insights before you agree.
What do we check?
- ✓ Price breakdown — is every item specified or only roughly estimated?
- ✓ Scope — what is and isn't included in this quote?
- ✓ Included / excluded — VAT, materials, transport, waste removal?
- ✓ Extra work — how and when is it communicated and approved?
- ✓ Warranty — on labour and materials, for how long and under what conditions?
- ✓ Schedule — is the completion date binding or only indicative?
- ✓ Payment — are instalments tied to progress or set arbitrarily?
- ✓ Terms — what are the cancellation and liability clauses?
- ✓ Missing information — what isn't stated but should have been?
- ✓ Questions for the supplier — concrete points to clarify.
Common risks
- ⚠ Electrical work in bathroom zones not done by an installer registered with a competent-person scheme — leaving you without the required building-regulations paperwork
- ⚠ No waterproofing (tanking) specified for the wet areas — the most expensive omission to discover two years later
- ⚠ Sanitaryware, taps and tiles not specified by brand or type
- ⚠ Tiling given in m² but without layout pattern, joint width or cutting waste
- ⚠ Removing and disposing of the old suite and tiles not included
- ⚠ Ventilation requirement not mentioned or no extractor included
- ⚠ Making good outside the bathroom — hallway walls, floors, doorways — excluded in the fine print
- ⚠ Warranty on tiling, sealant and grouting unclear or too short
Example questions for your supplier
After our analysis we send you concrete questions to put to the supplier. For example:
- 1 "Who signs off the electrical work — are you registered with a competent-person scheme?"
- 2 "What waterproofing/tanking is included in the wet areas, and to which standard?"
- 3 "Are all materials specified including brand, type and colour?"
- 4 "Are plumbing and electrical work fully included in this amount?"
- 5 "Is removing and disposing of the old suite and tiles included?"
- 6 "What warranty applies to the tiling, the sealed joints and the installations?"
