Gas Safe boiler installation in London for flats, houses and rental properties. Most like-for-like swaps are completed in 1 day (access depending).
Call us for a straight answer, or send photos (boiler + controls + pipework) and we’ll tell you what’s needed and what’s optional.
People call us after the same two moments: the “no hot water” morning, or the engineer who turns up, sighs, and says “it’s had a good run”. If that’s where you’re at, you don’t need a lecture — you need a calm plan and someone who’ll do the job like they live there.

You’ll see “supply and fit” offers everywhere. The boiler is the shiny bit — but the cleaning, protection, controls and commissioning decide whether you forget about it for 10+ years or keep googling error codes at 7am.
We look at bathrooms, hot water demand, water pressure, pipework size and how the home is used. Then we recommend what fits — not “biggest boiler = safest”.
Helpful before any quote: boiler sizing guide.
London installs often depend on flue position and condensate routing — especially in flats, conversions and side returns. We plan this properly so it stays safe, compliant and reliable.
If you’re unsure: flue rules + condensate guidance.
A new boiler on a dirty system still suffers. We assess whether you need a chemical clean or power flush, then fit the right protection so the boiler isn’t being set up to fail.
We set sensible flow temps, check pressures, confirm safe operation, register warranties, and walk you through controls so you’re not heating the house like it’s 2003.
Not sure if you need a replacement or a repair? See boiler repairs, and if it’s “beyond repair”, we’ll move you onto a proper install plan.
A “boiler swap” can be simple — until you factor in London property reality. This is the stuff that changes time, cost and feasibility (and why the best installation pages sound like surveyors).
Common constraints: limited cupboard depth, restricted flue options, strict access windows, parking/loading limits, and management company rules in blocks.
We plan around: the flue route, condensate routing (including pumps if needed), ventilation, and realistic access so install day doesn’t fall apart.
Replacing a boiler in a London flat often means tighter access, stricter flue/condensate planning, and coordination with building rules. We’ll tell you early if anything could slow it down — and how we’d solve it.
Houses usually give more flexibility, but can come with old pipework, tired controls, sludge, undersized gas runs for upgrades, or awkward relocation requests.
We check: pipe sizes, system condition, control upgrades, and whether relocation is genuinely worth it.

We keep this page focused on how installs are done properly. For real-world fitted price ranges and what changes the quote, use the two cost guides below — they answer 90% of “what will it cost me?” questions before you even pick up the phone.
Typical fitted ranges, swaps vs conversions, common extras, and what a proper quote should include.

Landlords and agents want it done safely, quickly, with the right paperwork — and without tenant chaos. We install boilers in occupied rentals and coordinate access so it stays calm and predictable.
We can work around tenant availability, keep disruption minimal, and communicate clearly about timings and scope. The goal is reliable heat/hot water with fewer call-outs.
If you need ongoing gas safety checks, tell us upfront and we’ll advise on the best next step for that property.

We’ll confirm what boiler type suits the property and demand, then install cleanly with protection and correct commissioning.
Budgeting belongs on the guide: new boiler cost + installation.
We’re not trying to be flashy — just reliable, clean and clear. Here are a few themes customers mention. See all reviews here: ARA Services reviews.
“My boiler went wrong… Abdul and his team came and fitted a new one… worked without taking a break, cleaned up…”
New boiler install — clean & fast“Prompt and efficient. Fitted a new boiler at a very competitive price… took away old boiler and all other waste…”
Install + waste removed“Excellent — will be recommending to neighbours and family. Many thanks for helping us out.”
Short-notice helpA straightforward like-for-like swap in the same location is often a day (access depending). If we’re moving the boiler, changing flue routes, upgrading controls, sorting pipework, or doing a deeper system clean, it can take longer — and we’ll tell you upfront.
Installed cost depends on boiler type, flue/condensate route, gas supply, system condition and access. For realistic fitted ranges and what should be included, see: boiler prices and installation cost in London.
Sometimes — but we’ll sanity-check it first. Wrong type/output can be a false economy. If you’re unsure, call us before you buy and we’ll tell you if it suits the property.
Yes — we install boilers in rental properties and can work around tenant access. If you need gas safety checks for the property, tell us upfront and we’ll advise on next steps.
Skipping protection and setup: no filter, inadequate cleaning, controls left at factory settings, radiators never balanced. The boiler runs… then faults and inefficiency show up later.
Send photos (boiler, controls, pipework around it, and cylinder if you have one) plus bathroom count. Use this contact form or call +44 7727 154 746.
Tell us what you’ve got and what you want to achieve. We’ll explain options clearly, flag likely extras early, and give you a plan that doesn’t fall apart on install day.
