Evidence before purchase Record current accommodation revenue, paid nights and available nights, with the dates the records cover. Describe comparable homes, dates, guest counts and full trip prices. Explain what supports an extra rate or additional bookings. Note other property or marketing changes that could affect a later comparison. The installed price Keep the full quote for the tub, delivery, lifting, access and base or structural work. Describe electrical supply, drainage, screening and safe access. Include the cover, steps, commissioning, training and assessment. Record full installed cost including VAT you cannot reclaim, and what the warranty and service support cover for this use. The operating budget Record representative metered electricity use with dates, weather and tariff. Include refill heating in the meter reading. Explain the water volume, safe refill frequency and combined water and drainage rate. Separate changeover labour from routine checks, visits, travel and supervision. Include chemicals, filters, testing, laboratory work, servicing, additional insurance and safety work. Allow for repairs and paid nights lost to downtime. Record ordinary costs for extra bookings and the share of added room income retained after booking and management deductions. Who will run it Refer to the competent assessment and written procedure. Agree who carries out the work, keeps records, checks results and covers absences or urgent faults. Keep closure limits, corrective action and reopening responsibility in the appropriate operating records. Explain the response to guests when the amenity cannot be supplied. Keep the insurer's response and relevant permission and specialist advice with the decision. Decision and review Compare conservative, central and optimistic income assumptions using the full operating budget. Record additional contribution, simple payback and alternatives for the same capital. Record the costs or quotes you still need before deciding. Explain your decision and set a useful review date. At that review, use actual room income and itemised costs, matched dates and other changes. Do not call a booking receipt or owner payout profit after every bill. This is a working investment record, not a safety assessment, operating procedure or forecast. Use competent advice for the installation and the rules that apply to it.
