Air conditioning installation in Dagenham Green
A new system normally needs a dedicated circuit from the fuse board. Under Part P, a new circuit is notifiable unless a registered competent person does it, and our NICEIC approval means we install and certify it ourselves. Air con, air conditioning, a split system: whatever you call it, in Dagenham Green it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Air conditioning around Dagenham Green
About 69% of homes in the Dagenham Green area were built between the wars, according to VOA council tax data, and the 2021 Census found about 48% of households in terraced houses. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. Terraces have little side access, so the outdoor unit typically goes on the rear wall or a flat roof, with the pipe run kept short. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Older streets near St Martin's Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. Close to Dagenham Dock station? A small study or box room used for work can usually be cooled with a single indoor unit.

System by system
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. The route is agreed before any drilling and kept as tidy as the building allows.
Outdoor unit positions
Where outside space is tight, the outdoor unit position shapes the whole design. Every option is checked on the survey and we flag any consent you may need.
How the visit works
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. Let us know who controls access to the building in Dagenham Green, as that saves time on the day.
- We survey the property, or work from your photos for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear the space around the indoor unit, or where it will go
- Mention any managing agent or landlord rules we need to follow

Advice
Dagenham Green: your questions answered
Can I get a fixed-price quote for air conditioning in Dagenham Green?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is Dagenham Green in your area for air conditioning?
Yes, Dagenham Green is within the area we cover. Just phone us on 07833 053749 or fill in the contact form with a few details.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy, so we explain why we’ve chosen a particular output.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. Balconies, flat roofs and rear walls can all work, subject to consent, and we check the options on the survey. This is general information, not legal advice.
After we’ve gone
So the system stays in good health:
- Report drips, noises or error codes straight away
- Close windows and doors while the system is cooling
- Book an annual service
We show you how to take the filters out and clean them. Clean them every few weeks when the system is in heavy use, or as the manual recommends, and keep space clear around the outdoor unit.
Clean the filters regularly, not just at the service. Blocked filters cut airflow and make the system work harder, which costs you more to run.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
