New Boiler Installation & Replacement in Great Dunmow — Fitted Within 72 Hours
In a suburban semi, the boiler is usually where it should be: kitchen or garage, short flue, sensible pipe runs. In the countryside around Great Dunmow, it's usually where it could go — at the time, by whoever was doing the work, in a house that has since been extended twice and rearranged once. We regularly survey Dunmow-area properties where the boiler hangs in what used to be the back wall of the house and is now a cupboard in the middle of it, with a flue extended through rooms that didn't exist when it was fitted.
- Most new boilers installed within 72 hours of survey
- Repositioning priced honestly when the boiler is in the wrong place
- At home in extended cottages, conversions and village properties
- Scale protection fitted as standard for CM6's very hard water
- Gas Safe registered — registration verifiable online

Continue on WhatsAppThat's the real character of installation work here: not one housing estate repeated, but scattered older houses, converted and extended cottages and farm buildings across the villages — Felsted, the Rodings, the Easters — each with a heating system that grew by accretion. We fit new boilers across Great Dunmow and its villages with most installations completed within 72 hours of the survey, and the survey here earns its keep more than almost anywhere else we work.
How a Great Dunmow boiler installation works
Four steps from first message to a commissioned boiler — with the reposition-or-replace question answered properly at the survey.

WhatsApp us
Send a photo of your current boiler and a line about the property — and if the house has been extended since the boiler went in, say so. It usually matters more than the boiler's age.

Survey
We look at the whole system, not just the appliance: where the boiler sits now, whether that's still the right place, flue options, gas run and condensate route. You get a fixed written quote — and where repositioning is worth considering, both options priced side by side.

Installation
Old boiler out, system cleansed and inhibited, new boiler in, magnetic filter fitted, system commissioned and demonstrated. A like-for-like swap is typically done in a day; a repositioned installation takes longer, and we'll tell you how much longer in writing.

Aftercare
We register the warranty, handle the building regulations notification, and cover our workmanship with 12 months' aftercare. An annual service keeps the manufacturer warranty valid.
The boiler is where 1987 left it — replacement is the moment to fix that
Houses around Dunmow grow sideways: a kitchen extension here, a converted outbuilding there, a bathroom where a bedroom was. The heating system rarely gets redesigned to match — pipework gets teased along, radiators get added to the ends of runs, and the boiler stays wherever it was first hung, increasingly far from the centre of the system it serves. The result is familiar to anyone in an older village house: rooms that never quite warm up, long waits for hot water at the furthest tap, and a flue arrangement that only makes sense historically.
A boiler replacement is the one time this can be put right at reasonable cost, because the expensive part — a new appliance and fresh connections — is happening anyway. Moving the boiler to the right place while it's being replaced typically adds a day and some pipework; moving it any other time means paying for most of an installation without getting a new boiler. At the survey we'll tell you straightforwardly whether repositioning earns its cost in your house — and in plenty of houses the honest answer is that it doesn't, in which case we'll say so and quote the simple swap.
Long gas runs, far-flung taps and other village-house realities
Repositioning is one decision; specifying for a spread-out house is another. Older rural properties often have long pipe runs the original system was never balanced for, gas supplies that need checking for adequacy before a modern boiler goes on the end of them, and hot water demands split across bathrooms at opposite ends of the building. The survey covers all of it: gas supply sizing, system balancing, and an honest conversation about whether your house heats better from one well-placed boiler or needs its system design adjusted while the work is open.
Some houses in the Dunmow villages are listed or sit within conservation areas. Where a flue or an external element of the work raises a consent question, we give you our written assessment of whether consent is likely to be needed and, where there's real doubt, confirm the position with the local planning authority before work starts — the final say on these matters is always theirs, and we treat it that way.
Dunmow's water: near the top of the county table
The CM6 supply measures around 363 ppm — very hard, close behind Maldon and level with the readings we see in Braintree and Witham, and roughly three-quarters harder than the UK average. In water like this, an unprotected heat exchanger furs up quickly, which is why every installation we do in the Dunmow area includes a full chemical cleanse, inhibitor and a magnetic filter as standard — not as an upsell, but because at 363 ppm they're what keeps the manufacturer's warranty meaningful. Heavier scale treatment beyond that baseline is a judgement call we'll make with you at the survey, based on your hot water use.
One firm, the whole job, in writing
Whether it's a straight swap in a modern house near the town centre or a repositioned installation in an extended cottage in the Rodings, the process is the same: a real survey, a fixed written quote with the specification and warranty confirmed, and most installations completed within 72 hours of the survey. Where a job needs longer — repositioning usually does — the timescale is agreed in writing before anything starts.
