A split on your wall is a purchase, and in Europe it is also a small regulated project: the outdoor unit may need a declaration at the town hall, it must stay under a noise limit at the neighbour’s window, only a certified person may connect it, it moves the letter on your energy certificate, and the grant or reduced VAT rate only applies if its conditions were met before the work. This kit sets out those five checks for ten countries, with the documents to ask for at each step.
Every rule names its text (Regulation (EU) 2024/573, Directive (EU) 2024/1275, the English permitted development rules, the Irish exemption, the French code de l’urbanisme, the Dutch Bbl, the German TA Lärm, the Italian free building glossary, the Spanish RITE…) and was checked on November 1, 2026; where a rule is set by the municipality, the kit says so instead of inventing a figure. We do not install or sell air conditioners and recommend no installer: the kit is independent.

Introduction
Fitting a split air conditioner or an air-to-air heat pump looks like a purchase: choose a model, accept a quote, book a day. In Europe it is also a small regulated project. The outdoor unit may need a declaration at the town hall. It must stay under a noise limit at your neighbour's window, and some countries write that limit in decibels. Connecting it is reserved by EU law to a person and a company certified for fluorinated gases. It changes the letter on your energy performance certificate, up or down depending on what it replaces. And depending on where you live, a grant, a tax relief or a reduced VAT rate may pay part of it, but only if you ticked their conditions before the work started.
This kit puts those five questions side by side for ten countries: England, Ireland, France, Belgium, the Netherlands, Germany, Austria, Italy, Spain and Portugal. Each rule names the text it comes from. Where the rule is set by your municipality, your region or your Land, we say so and mark it Local rule: check with your municipality, rather than inventing a figure.
How to use it: read chapter 1 for the map of the five checks and your starting point. Chapter 2 gives the permit rules for your country, chapter 3 the noise limits with a method to estimate the level at the neighbour's window, chapter 4 the installer's certification and what it must cover. Chapter 5 explains the energy performance certificate, chapter 6 the grants, tax reliefs and VAT rates. Chapters 7 and 8 are the two checklists, before the quote and before you accept the work. Chapter 9 holds the three letters (municipality, neighbour, installer) and chapter 10 the full country comparison table. Print it (Ctrl+P or Cmd+P, then "Save as PDF", or print on paper). The noise estimate and the quote comparison are also on your access page as spreadsheets.
The rules were checked on November 1, 2026 against the official texts or the official pages that apply them, listed in the Sources. Grant and tax figures are those published by the scheme or the tax authority on that date; they change with budget laws, sometimes during the year. The one study cited has its DOI.
Chapter 1: The five checks behind one outdoor unit
A split system has two parts: the indoor unit on your wall and the outdoor unit, which holds the compressor and the fan, joined by two copper pipes, a cable and a condensate drain. An air-to-air heat pump is the same machine, sold for heating; most splits sold in Europe are reversible. Everything in this kit applies to both. Five separate questions decide whether the installation is lawful, quiet, properly done and paid for at the right price, and different people answer each of them.
The five questions, and who answers them
| Check | The question | Who decides | Chapter |
|---|---|---|---|
| 1. Permit | Does the outdoor unit need a permit, a declaration or nothing? Is the building or the area protected? | The municipality or planning authority; the heritage authority | 2 |
| 2. Noise | How loud may it be at the neighbour's window, by day and at night? | National or regional law, often the municipality; a court if a neighbour complains | 3 |
| 3. Installer | Is the person who connects the pipes certified for fluorinated gases, and is the company? | EU Regulation 2024/573, applied by a national certification body | 4 |
| 4. Certificate | What does the installation do to your energy performance certificate? | The national calculation method, applied by a qualified assessor | 5 |
| 5. Money | Is there a grant, a tax relief or a reduced VAT rate, and what must be done before the work? | The national or regional scheme, the tax authority | 6 |
In a flat there is a sixth decision maker, the building: the co-owners, the freeholder or the landlord. Chapter 2 names the rule for each country in one line, because the façade and the roof are almost always common property, and a yes from the town hall is worth nothing without the building's agreement.
Why the order matters
The five checks are not independent, and doing them in the wrong order is how money is lost.
- The money conditions come first. Almost every grant and tax relief in this kit requires something before the work starts: an application, a certified installer, an energy certificate issued before the works, or equipment from an approved list. A heat pump already fitted cannot be made eligible afterwards.
- The position decides the permit and the noise. The same unit can be exempt on a rear wall and need a declaration on the street front; it can comply at 8 metres from the neighbour's bedroom and fail at 2. Choose the position with the installer on the survey, then check the permit and the noise for that position.
- The installer's certificate is checked before you sign. It costs nothing to ask for the certificate number and to look it up; it costs the warranty, the grant and possibly a fine to discover afterwards that the installer was not certified.
- The certificate is updated after the work, with the documents the installer hands over. If you are about to sell or let, or if a tax relief needs a before-and-after certificate (Spain), plan both certificates from the start.

| Italy | Free building activity for air-to-air heat pumps below 12 kW | Differential criterion: 5 dB(A) by day, 3 at night inside the dwelling | Income tax deduction of 50 % (main residence) or 36 % in 2026 | 10 % on works in homes, with a special rule for "significant goods" such as air conditioning equipment |
| Spain | Set by each ayuntamiento | Ley del Ruido and RD 1367/2007, applied by municipal ordinances | Income tax deductions of 20 % or 40 % in 2026, proven by energy certificates before and after | Standard rate |
| Portugal | Set by each municipality | Regulamento Geral do Ruído: incomodidade criterion | National programmes when open: check the Fundo Ambiental | Not checked for air-to-air: ask the installer which rate applies and why |
Chapter 10 holds the full table, with the installer certification and the energy certificate for each country.
Your starting point (fill in)
| Question | Your answer |
|---|---|
| Country, region, municipality | |
| House or flat? Owner or tenant? | |
| Listed building, conservation area or protected perimeter? (ask the municipality if unsure) | |
| Where could the outdoor unit go? (wall, ground, flat roof, balcony; front or rear) | |
| Distance from that position to the nearest neighbour's window (m) | |
| What heats the home today? (gas, oil, electric radiators, nothing) | |
| Do you plan to heat with the new system? | |
| Will you sell or let within two years? | |
| Energy certificate: current letter and date | |
| Budget and deadline |
With these ten answers, read the section of chapter 2 for your country, then the noise method of chapter 3 for the position you have in mind. If the answer to "what heats the home today" is gas, oil or electric radiators, read chapter 6 before you ask for quotes.

Frequently asked questions
How do I receive the guide?
Right after payment you are taken to your guide page, with the spreadsheet to download. Bookmark it: the link stays valid and always shows the latest version. To keep a PDF, save it from your browser (Ctrl+P or Cmd+P, then "Save as PDF"): the layout is made for printing. Stripe emails you the receipt, and "Find my purchases" at the bottom of every page sends the link again.
Is VAT included? Is it a subscription?
€39 is the total you pay, VAT included, once. There is no subscription and nothing is charged later. Your card details go to Stripe and never reach us.
Is it up to date with the 2026 changes?
Yes, as of November 1, 2026: the Irish exemption that allows a heat pump at the front of a house since July 27, 2026, the French 5.5 % VAT rate for eligible air-to-air heat pumps since July 18, 2026, the Belgian 6 % VAT rate on heat pumps in 2026, the Italian and Spanish tax reliefs for 2026, and the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps are all covered. Grant amounts change with budgets: the kit tells you where to check the current figure.
My country is not in the list. Is it useful?
Chapters 3, 4, 5, 7 and 8 rest on EU law and apply in every member state: the F-gas certification, the sound power on the label, the buildings directive and the two checklists. For the national rules, the fill-in tables and the letter to the municipality tell you what to ask and whom.
I live in a flat and the building refused an outdoor unit. Is this the right guide?
Not on its own. This kit is about installing a unit with an outdoor part; chapter 2 gives the building’s rule for each country in one line. If the building said no, our guide to cooling a flat without an outdoor unit covers monoblocs, portables, request letters and what a building can refuse.
Is it legal advice or a guarantee of a permit or grant?
No. It tells you which text applies, who decides and what to file, and gives you the documents to do it; it does not say what your municipality, your neighbour or your tax office will answer. For a dispute, ask a lawyer or an acoustician.
What is the guarantee?
The guide is guaranteed as described: if it does not open or contains an error, we fix it, and if we cannot, we refund you in full (refund policy in the terms of sale). Write to admin@tech-bharat.com. A duplicate payment is always refunded.
