What's In The Quote
Everything you'd expect from a proper install — included.
A lot of cheap boiler quotes hide the things that actually matter — the filter, the flush, the controls, the paperwork. We don't. Every fixed-price Macara quote covers the lot so you know exactly what you're paying for.
A properly sized boiler
We work out the right boiler size based on your property, radiator load, and hot water demand — not by picking whatever's on a special offer that week.
Magnetic system filter
Fitted as standard on every installation to catch sludge and debris, protect the new boiler, and keep the manufacturer warranty valid for its full term.
Power flush where needed
If the existing system is heavily sludged, we'll power flush it before commissioning the new boiler. No rushed installs over a dirty system.
Gas Safe notification
We notify Gas Safe of the new installation on your behalf and provide the paperwork confirming everything was signed off correctly.
Warranty registration
We register the manufacturer warranty for you — up to 10 or 20 years with some brands — so you don't have to chase paperwork after the job is done.
Boiler Brands We Install
A short list of brands we actually trust.
We don't fit every brand under the sun. We fit the ones that are reliable, well-supported, and backed by proper warranties — so when you pick up the phone in five years, parts and support are still easy to come by.
Up to 12 years
Worcester Bosch
A long-standing favourite across Scotland. Reliable, well-supported, and available with extended warranties on many models when installed by qualified engineers.
Up to 10 years
Vaillant
German engineering with a strong reputation for efficiency and longevity. A good choice where quiet operation and long-term reliability matter most.
Up to 10 years
Ideal
Manufactured in the UK, Ideal boilers offer great value for money without cutting corners on build quality. A sensible mid-range option.
Up to 10 years
Baxi
Another long-established British brand — dependable, straightforward to service, and widely supported across the Lothians for parts and aftercare.
Up to 10 years
Viessmann
Premium German build with excellent efficiency figures. A strong option for homeowners who want the best possible long-term performance.
What We'll Tell You Straight
Not sure which brand is right for you?
We'll talk you through the real differences — efficiency, reliability, warranty terms, and running costs — at the free survey, without pushing the most expensive option.
On Installation Day
What actually happens, hour by hour.
A straight combi swap is usually a one-day job. A full system conversion takes two. Either way, here's what to expect when our engineers turn up at your door.
01
Arrival and protection
We arrive first thing, put down dust sheets and floor protection, and isolate the existing gas, water, and electrical supplies before any work starts.
02
Drain-down and removal
The existing system is drained properly. The old boiler is disconnected, removed, and the location is prepared for the new unit.
03
Pipework, flue, and fitting
New pipework is run where needed, the flue is fitted to manufacturer specification, and the new boiler is mounted securely.
04
System flush and filter
We flush the heating circuit, fit the magnetic filter, and dose the system with inhibitor to protect the new boiler long-term.
05
Commissioning and testing
The boiler is commissioned to manufacturer spec, gas rate and flue gas analysis are checked, and every radiator is tested under load.
06
Handover and clean-up
We walk you through the new controls, complete the benchmark and Gas Safe paperwork, and leave the property clean and tidy.
Free home survey before any price is confirmed
We don't quote boilers blind over the phone. A Gas Safe engineer visits the property, checks the existing setup, and sizes the replacement to your heating and hot water demand. Only then do you get a written quote covering the boiler, the install, and everything we include as standard.
- Free home survey, no obligation to go ahead
- Written quote covering everything in one price — no surprises
- Time to compare, think, and ask questions before you decide
Long warranties and real aftercare
Because we're a Gas Safe installer fitting approved brands, we can register manufacturer warranties of up to 10 or 12 years on many boilers. Annual servicing keeps the warranty valid for its full term — and because we're local, you're never more than a phone call away from the same team that fitted it.
- Warranty registration handled on your behalf
- Annual service reminders from us, not a call-centre
- Local aftercare — the same team, not a subcontractor

For most Edinburgh homes, a new combi boiler installed costs between £2,200 and £3,500, depending on the brand, model, and how much pipework needs changing. System and regular boiler installs typically run £2,800 to £4,200 once the cylinder and controls are factored in.
