Radiator installation, East London & Essex
New radiators, towel rails
and replacements —
fitted, balanced, leak-free
From a single rad swap in a bedroom to a full-house upgrade with vertical designers and chrome towel rails, we move, replace, balance and bleed. Tidy pipework, clean walls, even heat in every room.
What it covers
Single swaps, designer upgrades and full-house re-rads
Radiators are the visible end of the heating system, the part the family actually interacts with, and the part that gets ignored when something else needs replacing. We see homes across East London and Essex with brand-new heating systems feeding 25-year-old radiators that are full of sludge, undersized for the room, or hung in the wrong place. The heat source can only do so much when the emitters are the bottleneck.
Our radiator work runs from the smallest job, a like-for-like swap with the same valves and the same fittings, to whole-house upgrades with vertical designer radiators in living spaces, chrome towel rails in bathrooms, and properly-sized panel rads in bedrooms. Single jobs are typically done in a single morning; whole-house upgrades run a day or two depending on access and re-piping required.
Every install ends with the radiators balanced individually using lockshield valves and flow-temperature measurement. This is the step that turns 'we fitted new radiators' into 'every room comes up to temperature evenly', and the step most installers skip.
What happens if you wait
An undersized or unbalanced radiator costs you comfort and money every winter
A radiator that's too small for its room never gets the space up to temperature, the heating system runs longer, the thermostat sits unhappy, and the energy bill creeps up. A radiator with cold spots at the bottom is full of sludge, the heat output is a fraction of what's printed on the spec sheet, and the sludge spreads through the rest of the system.
Radiators sized by guesswork rather than heat-loss leave bedrooms, conservatories and rear extensions chilly even on full.
Black water from a removed radiator means magnetite is circulating through the system and into the heat exchanger.
Buying a designer radiator that's beautiful but undersized means the room never gets warm, and the radiator has to be replaced again.
Common mistakes we fix every week
- Picking a radiator by looks alone without checking BTU output for the room.
- Fitting a new radiator without balancing the rest of the system afterwards.
- Bleeding a cold-bottom radiator (it's sludge, not air).
- Reusing old valves on a new radiator without checking the seals.
- Leaving a TRV on the wrong side of the radiator, they're handed for a reason.
- Skipping a system inhibitor top-up after draining down.
Our process
A predictable, step-by-step system, no surprises, no upsells
- STEP 01Survey & spec
Room measured, heat-loss calculated, radiator and valve options agreed in writing.
- STEP 02Drain & isolate
System drained safely, old radiator and pipework removed cleanly.
- STEP 03Install
New brackets, neat pipework drops, valves fitted correctly handed.
- STEP 04Re-fill, vent & inhibit
System re-filled, vented, inhibitor topped up to correct concentration.
- STEP 05Balance & test
Every radiator on the system re-balanced; leak test and 30-minute warm-up demonstration.
What you get
Concrete outcomes, not vague promises
BTU calculation drives the spec, no cold bedrooms because the rad looked nice in the catalogue.
Vertical, column, anthracite, chrome, we work with all the leading brands and styles.
Neat drops, level brackets, valves correctly handed, visible finishes treated as a finish, not just plumbing.
Whole system balanced, not just the new radiator. Every room benefits.
After any drain-down, inhibitor concentration is checked and re-dosed if needed.
All radiator work covered in writing. Manufacturer warranties on the radiators sit on top.
Technical detail
What a properly fitted radiator job involves
Radiator work is one of those jobs that looks simple from outside and is full of small decisions that decide whether the job is good or bad. Here's what to watch for.
Sizing, BTU vs Watts vs room demand
Radiator output is published in both BTU/hour and watts at a standard delta-T (usually 50°C). Real-world output depends on the flow temperature of your system, modern condensing systems run cooler, so the same radiator outputs less in a real install than in the catalogue. We size for actual system flow temperature, not the catalogue figure.
Valves, TRVs, lockshields and handing
Most radiators take a TRV on one side and a lockshield on the other. Modern TRVs are bi-directional but older heads (and most decorative chrome valves) are handed, flow must enter through the TRV side. Getting this wrong means the TRV doesn't regulate properly and the room temperature wanders.
- Standard TRVs for individual room control
- Smart TRVs for app-based zoning
- Lockshield on the opposite side for balancing
- Drain-off valves on lowest points
Vertical and designer radiators
Vertical radiators are popular in living rooms and hallways where horizontal wall space is at a premium. They work hydraulically just like horizontal panels but need careful pipework planning, usually a longer pipe drop or chase to make them sit flush. We plan the route before quoting so there are no surprises.
Bathroom towel rails, chrome vs coloured
Chrome towel rails look beautiful but output less heat per metre than a standard white panel, the chrome surface is a worse heat radiator. In a small bathroom that's fine; in a large family bathroom you may need a dual-fuel rail or a hidden panel radiator alongside. We'll model the heat demand before specifying.
Frequently asked
Straight answers to the questions East London & Essex homeowners ask us most
How much does a radiator installation cost?+
A single like-for-like swap is a fixed call-out fee covering up to 90 minutes on site, plus the radiator itself. Designer/vertical installs and full-house re-rads are quoted individually after survey.
Can I supply my own radiator?+
Yes, happy to fit a customer-supplied radiator, though we won't warranty parts we haven't supplied. We'll always check the model is fit for the room before fitting.
Will you need to drain the whole system?+
Usually a partial drain-down is enough, we isolate the relevant section, refit the radiator, then refill, vent and re-balance. Full drain-downs only on whole-house re-rads.
Why is my new radiator cold at the bottom?+
Sludge, magnetite that's settled in the bottom of the radiator. Either the system needs flushing or the radiator needs removing and flushing individually. We'll diagnose properly rather than just bleeding it.
Can I move a radiator to a new wall?+
Yes, we'll plan the pipework route, re-pipe under floors where needed, make good and rebalance. Surveys are free.
Do you fit vertical radiators?+
Yes, including tall column radiators, vertical flat panels and designer brands. We plan the pipework route before quoting.
Will my heating still work the same?+
After install we re-balance the whole system, so generally the heating improves, rooms come up more evenly and the heating system short-cycles less.
Do you fit dual-fuel towel rails?+
Yes, chrome and coloured towel rails with a heating element so they run year-round, with the central heating off in summer.
How long does a single radiator swap take?+
Usually 90 minutes for a like-for-like swap in an accessible location. Longer if pipework has to be modified or the wall needs new fixings.
Is there a guarantee on the install?+
Yes, workmanship guarantee in writing on every job. Manufacturer warranty on the radiator itself sits on top.
