EH33 · East Lothian · for landlords
Tranent boiler installation without guesswork
Tranent sits on the ridge above the A1 — a former mining town with dense High Street stone terraces, post-war council estates around Loch Park and Lindores Drive, and a heavy run of new-build family homes spreading out toward Windygoul and Wallyford. The mix means we run two very different jobs in EH33 in the same week: tight combi swaps and gas safety certificates in the older terraces, and unvented-cylinder annual service work plus underfloor-heating commissioning in the modern estates.
Older High Street and Civic Square terraces have narrow kitchen footprints — combi siting, condensate routing and flue access drive most of the survey conversation rather than boiler kW. For boiler installation, that changes the survey, specification or working sequence before price is agreed.
As Vaillant Advanced Installers we install gas, oil and LPG boilers across Tranent with manufacturer-backed warranties of up to 12 years. A like-for-like swap is usually a single-day job; a full system upgrade — new flue route, magnetic filter, smart controls, system flush and a fresh expansion vessel — typically runs to two or three days on site. We always quote in writing after a proper survey, never over the phone, and we never use commission-based salespeople in your home. This page is specifically for landlords who need to compare a surveyed replacement with clear warranty and system-upgrade advice.

Property and access context
What changes the job in Tranent
- Older High Street and Civic Square terraces have narrow kitchen footprints — combi siting, condensate routing and flue access drive most of the survey conversation rather than boiler kW.
- Windygoul and the newer Persimmon and Cala estates run unvented Megaflo or Telford cylinders on first or second floor — annual G3 inspections and expansion-vessel pressure checks are core EH33 work for us.
- Strong landlord and letting market across the older terraces — block-booked CP12 rounds with same-day digital certificates and 30-day renewal reminders are a regular slot.
- Edinburgh-commuter retrofits typically come paired with smart-controls upgrades (vSMART, Hive, Tado) and magnetic-filter additions on existing systems.

Questions shaped by Tranent properties
Can you fit a new combi in a narrow Tranent High Street terrace?+
Yes — tight kitchen and cupboard installs are routine in EH33. We survey access, plan condensate and flue routing before quoting, and pick a footprint-friendly Vaillant or Worcester model that actually fits the available space without compromising serviceability.
Do you service the unvented cylinders in the new Windygoul estates?+
Yes — our engineers are G3-qualified and we cover the Megaflo, Telford and Joule cylinders fitted across the modern Tranent estates. Annual service keeps the manufacturer warranty live and catches expansion-vessel pressure drop before it becomes a discharge problem.
What should be checked before quoting boiler installation at this Tranent property?+
Older High Street and Civic Square terraces have narrow kitchen footprints — combi siting, condensate routing and flue access drive most of the survey conversation rather than boiler kW. We confirm that point on site, then match the boiler installation specification to the actual building and access rather than assuming every EH33 address is alike.
Is this page aimed at landlords?+
Yes. The recommendations prioritise landlords who need to compare a surveyed replacement with clear warranty and system-upgrade advice. If the building or occupancy differs, the survey is where we adjust the plan.
What warranty will I get?+
Up to 12 years on Vaillant boilers as Advanced Installers; 7–10 years typical on Worcester Bosch, Ideal and Baxi. We register the warranty for you on the day of commissioning.
How disruptive is a boiler swap?+
A like-for-like combi swap usually means one day with the heating off. A full system upgrade or a back-boiler-to-combi conversion runs two to three days. We'll always tell you up front what to expect.
