1. Define your new kitchen
A clear brief helps professionals give sharper prices and better advice. Here is what to keep in mind before you get quotes.

2. Build a realistic budget
Use the price guide ranges to choose a budget band that fits your home and goals. Separate the cost of core items like cabinets, worktop and appliances from optional upgrades, and keep a small buffer for unexpected issues such as hidden defects or extra electrical work.

3. Check rules, timing and logistics
Before requesting quotes, confirm any building rules about work hours, noise, waste disposal and use of lifts or common areas.
- Think about the best period for works, how long you can live without a full kitchen, and where materials and tools can be stored safely during the project.
- Think about what absolutely needs to change, what would be nice to improve, and what can stay as it is for now.
- Being honest about your priorities and limits makes it easier to decide where to invest more and where to keep things simple.
4. Prepare your brief for professionals

Qué tener en cuenta antes de instalar una fosa séptica
Even kitchens of similar size can end with different budgets. These are the factors that most often push costs up or down.
Respetar la normativa aplicable
La instalación de fosas sépticas está sometida a diferentes normativas. En primer lugar, al Código Técnico de la Edificación. Además, hay que tener en cuenta la Directiva 91/271/CEE y la legislación nacional sobre el tratamiento que deben seguir las aguas residuales urbanas Junto a ello, es necesario tener en cuenta que las normativas autonómicas o locales también pueden introducir criterios particulares a la hora de instalar una fosa séptica. Y, por último, son de aplicación normativas técnicas (UNE ISO-EN 12566 y UNE-EN 13636 V2). Dado que la normativa aplicable es amplia y variada, es importante que la instalación de la fosa séptica corra siempre a cargo de profesionales.
Permisos necesarios
La instalación de una fosa séptica requiere de la obtención de un permiso municipal. Los criterios, no obstante, pueden variar de unas localidades a otras (licencia de obra menor o mayor). Por lo tanto, es necesario consultar previamente en el Ayuntamiento. Hay que tener en cuenta un aspecto añadido: en algunos municipios la normativa obliga a conectarse a la red de alcantarillado municipal siempre que la distancia de la vivienda al punto más cercano no supere un número de metros determinado. En aquellos casos en los que se tengan intención de instalar una fosa séptica en una comunidad de propietarios, el paso previo será solicitar y obtener la autorización de la junta.
Capacidad y número de cámaras
Las fosas sépticas pueden ser de diferente capacidad. De esta forma, se pueden dimensionar para que se adapten perfectamente a las necesidades del inmueble según el uso que de la instalación se haga (permanente u ocasional) y según el número de ocupantes de la vivienda. Una fosa séptica para dar servicio a una vivienda con cuatro usuarios debe tener una capacidad aproximada de 1.500 litros. También puede variar el número de cámaras de la fosa séptica. Las más sencillas solo tienen una, mientras que las más habituales llevan dos (decantador y digestor). También hay fosas de tres cámaras, más eficientes, pero menos habituales en viviendas.
Ubicación
Una fosa séptica debe cumplir unos requisitos en lo que a ubicación se refiere. En primer lugar, no se deben instalar o construir en terrenos poco firmes o pantanosos. En segundo lugar, es imprescindible que el espacio elegido tenga un buen acceso y que en el perímetro de la instalación haya espacio libre como para poder realizar las tareas de mantenimiento básicas sin problemas. Además, una fosa séptica no debe estar a menos de 5 m. de la vivienda ni a menos de 15 m. de corrientes de agua. Si en las cercanías hay pozos de agua, esa distancia se eleva a 30 m. y a 60 m. si hay embalses.
