Hotel renovation in Mallorca: building work, installations and energy

A hotel renovation in Mallorca is decided in summer, designed in autumn and carried out during the winter closure; if it needs a licence, which in Palma was taking 9 to 12 months in early 2026, the design starts a year earlier. In 2026, many hotels reopened at the end of March, while those undergoing full renovations planned to reopen between 22 May and 1 June. If your hotel stays open in winter, like eight out of ten in Palma, we work in phases.

We renovate rooms, bathrooms, common areas, kitchens and façades, and we renew the installations that weigh most on your profit and loss account: hot water, HVAC and electrics. A site manager coordinates our whole team, and a building services engineer speaks the same language as your head of maintenance.

  • Rooms and bathrooms in blocks, with a floor-by-floor schedule
  • Common areas, reception, restaurant and kitchen
  • Façade, roof and windows with thermal and acoustic insulation
  • Replacing oil boilers with heat pumps
  • HVAC with zone control and heat recovery
  • Solar panels and batteries on the roof and car park
  • Energy data for your plan de circularidad (circular economy plan)
  • Grant applications, such as the Factor de Insularidad

Step by step

Timeline of a hotel renovation in Mallorca

We count back from your reopening date. Here is an example for reopening at the end of May 2027 with bathrooms and finishes in blocks of rooms, under a comunicación previa (prior notice to the council): decision in November, work from December to April and handover in mid-May. If the renovation needs a licence, we apply for it this winter and build during the following closure: in Palma, the standard procedure was taking 9 to 12 months in early 2026.

Book a technical visit

  1. Summer: decision and technical visit

    We visit the hotel with your head of maintenance, check the installations and consumption, agree the scope and quote, and confirm the team reserved for you.

  2. Autumn: design, permits and grants

    Project, comunicación previa and grant applications. If a licence is needed (legal deadline 3 months, 9 to 12 in practice in Palma), we apply a year ahead.

  3. Winter: works while the hotel is closed

    We carry out the work during the closure, with the site manager at the hotel and a weekly report for owners and management.

  4. Spring: testing and handover

    We test the installations, clean and hand over with time to spare before the reopening, with all the technical documentation.

  5. Season: aftercare

    A 5-year written guarantee and the same contact if something fails in the middle of the season.

What we guarantee

Works that suit the owners, management and maintenance

In a hotel, more than one person decides. Each one gets in writing what they need to make the decision.

  • Owners: price and deadline

    A fixed, itemised quote, works schedule and reopening date in the contract, with a penalty if we run late.

  • Management: undisturbed guests

    If the hotel stays open, we work in blocks of rooms and keep the noisy phases to the hours set by each municipality.

  • Maintenance: one engineer

    One technical contact for boilers, HVAC, hot water and electrical panels, with drawings and data sheets for every unit at the end.

  • Energy, built into the quote

    Water, electricity and gas account for 15 to 20% of a hotel's operating costs. We work out how much each measure saves before you decide.

  • Grants handled for you

    We prepare and submit the applications, such as the Factor de Insularidad, a Balearic government scheme awarded first come, first served. All the calls for applications are under grants and subsidies in the Balearics.

  • Photos and a report every week

    Owners and management can see how the work is progressing, even when they are off the island.

Good to know

Energy obligations and grants for hotels in the Balearics

These rules and grants shape what makes sense in your next renovation. Here they are in brief, with their sources.

Oil boilers: deadline 1 May 2030

Hotels, tourist apartments and agroturismos (rural hotels) must replace heating installations running on heating oil or fuel oil, including existing ones, with less polluting ones, unless this is shown to be technically impossible. If the hotel was built or had its heating replaced between 2019 and 2021, the deadline is 1 May 2031. Failing to do so is a very serious offence, with a fine of €100,000.

Plan de circularidad

Every hotel, tourist apartment complex or agroturismo needs a plan covering up to five years, with an annual assessment. For energy, it measures the carbon footprint per overnight stay, the energy rating, renewable capacity and storage.

Factor de Insularidad 2026‑2027

For businesses under the de minimis rules (no more than €300,000 of aid in three years): 70% for solar panels (up to 500 kWp) and heat pumps and 45% for batteries, for work from 1/1/2026. Without de minimis, 40 to 60% for solar panels and heat pumps and 30 to 40% for batteries, depending on company size, and only work started after the application counts. Applications until 28/02/2027, first come, first served.

ITS grants 2026: now closed

The sustainable tourism tax call for energy efficiency (€3 million, projects of €10,000 to €300,000 excluding IVA) accepted applications until 30/09/2026. Solar panels were excluded, only work started after applying counted, and it could not be combined with other grants for the same measure. If a new call opens, we prepare your application.

How long does it take to renovate a hotel?
It depends on the scope. Replacing bathrooms and finishes in blocks of rooms fits into one winter closure. A full renovation with new installations may need more than one low season and be done in phases. On top of that come the design and the permits: in Palma, the legal deadline for the licencia urbanística is 3 months, but the standard procedure was taking 9 to 12 months in early 2026 (Ara Balears, 01/10/2026). We agree the schedule with you before signing.
Can you finish the work before the season's reopening?
Yes, if we plan it in time. The reopening date goes in the contract, with a penalty if we run late, and the schedule is built backwards from that day, with time for testing, cleaning and training your maintenance team. For a winter closure, the ideal is to decide in summer and have the project ready in autumn.
Can I keep my hotel running during the renovation?
Yes, by working in phases: we close off blocks of rooms or floors, separate the access routes and concentrate noisy work in the permitted hours. In Palma, from 1 May to 30 October, noisy work in areas with heavy tourist traffic is only allowed from 11am to 7pm. In Calvià, from 1 May to 31 October, from 10.30am to 1pm, Monday to Friday.
How much does it cost to renovate a hotel or a room?
It depends mainly on whether you replace the installations or just the finishes, and published guides give very wide ranges. So that you have a figure quickly, at the technical visit we assess a typical room and give you the price per room and per block, with the grants you can apply for already deducted. That way you decide how many blocks to renovate this winter, and then you get the fixed, itemised quote.
What grants are there in 2026 for energy efficiency in hotels in the Balearics?
The main one right now is the Factor de Insularidad: under the de minimis rules, 70% for solar panels and heat pumps and 45% for batteries; without them, 40 to 60% and 30 to 40% depending on company size, and only for work started after applying. Applications are accepted until 28/02/2027, first come, first served. The sustainable tourism tax (impuesto de turismo sostenible, ITS) call for energy efficiency closed on 30/09/2026. We prepare and submit the applications.
How do we replace the oil boiler with a heat pump?
First we measure the hotel's real hot water and heating consumption and size the heat pump in Mallorca, usually with storage tanks. Then we plan the changeover so you are never without hot water: with the hotel closed or circuit by circuit. The tourism law requires oil and fuel oil boilers to be removed before 1 May 2030.
What does the plan de circularidad require on energy, and how do we comply?
The plan de circularidad is mandatory for hotels, tourist apartments and agroturismos. For energy, it records indicators such as the carbon footprint per overnight stay, the building's energy rating, installed renewable capacity, storage capacity and the share of self-generated energy. A renovation with heat pumps, solar panels and batteries improves all of them, and we give you the data to document it.
