How the call-out fee works in Tower Hamlets
One rate, any hour, no night or weekend premium on the call-out itself. There are two situations where you do not pay it at all, and both are worth knowing before you ring.
Charged once, 24 hours a day. Covers the engineer attending and diagnosing the fault. Labour is billed separately at from £110 an hour on weekdays and from £140 out of hours.
If the work runs past three hours, the call-out fee is waived and you pay labour and materials only. You are not charged twice for the same visit.
No call-out fee on any visit, on every property, for landlords, property managers, block managers and letting agents on a collaboration contract. Labour and materials only. Ordinary emergency call-outs pay the standard £60. See our property manager terms.
Every figure above is published in full on our pricing page, and the price for your job is agreed in writing before any chargeable work starts.
The densest borough in England, and four homes in five are in a block
The 2021 Census recorded 80.7% of Tower Hamlets' 120,542 households in a purpose-built block of flats or tenement. Across London the figure is 40.3% and across England and Wales 16.7%. Only the City of London is higher. Terraced houses account for 8.8%, part of another converted building such as a former warehouse for 3.5%, semi-detached for 2.3% and detached for 0.9%. The council's own borough profile puts it plainly: 88% of the properties in Tower Hamlets are flats.
Density follows. The ONS records Tower Hamlets as the most densely populated local authority in England and Wales at the 2021 Census, at 15,695 residents per square kilometre, ahead of Islington on 14,578 and Hackney on 13,611. The council notes this had risen to 16,478 per square kilometre by mid-2022, almost three times the density of London as a whole and more than 37 times that of England. Ward figures range from about 10,200 per square kilometre in Bow West to about 21,700 in St Dunstan's.
That is not trivia. It is why almost every emergency here is a shared-services problem. The stopcock that isolates your flat is frequently in a riser cupboard on the corridor, not under your sink. The failed section is often on a communal cold feed serving twelve floors. And water leaving a fault on the eighth floor is a problem for the sixth, fifth and fourth before anybody on the eighth notices. The first quarter of an hour of a job in a Tower Hamlets block is spent finding the correct isolation point, and an engineer who mostly works houses loses that quarter hour.
Height brings its own physics. In a tall block the cold supply is boosted and zoned, so pressure and flow vary by floor and a fault can present as low pressure several storeys away from where it actually is. Pumped and pressurised systems replace gravity, which means expansion vessels, pressure reducing valves and filling loops become the failing components rather than ball valves and loft tanks. The council's own building safety pages record that it manages 78 high-rise buildings, defined as at least 18 metres or 7 storeys with two or more residential units, and its Local Plan classes anything over 30 metres as a tall building, noting a surge in tall building development in clusters at Aldgate, the Isle of Dogs and along the Thames waterfront.
More than a quarter of homes have no gas appliance at all
28.1% of Tower Hamlets households heat with electricity only. That is the third highest share of any local authority in England, behind only the Isles of Scilly and the City of London, and more than twice the London figure of 12.6%. A further 8.3% are on a district or communal heat network only, and 3.1% recorded no central heating whatsoever. Mains gas alone accounts for 48.4%, which is the second lowest of any London borough and well below London's 70.5%.
Put together, roughly four in ten Tower Hamlets homes have no individual gas boiler to fix. When those households lose hot water the fault is an immersion element, an unvented cylinder, a thermostat, an expansion vessel, a TP valve, an electric shower or a heat interface unit. Calling a gas engineer achieves nothing, and a surprising number of people spend a cold evening finding that out. Our engineers hold G3 qualifications for unvented hot water cylinders and carry elements, thermostats, expansion vessels and TP valves as van stock, so most of these clear on the first visit.
The heat network side is more specific still. Tower Hamlets Council's own local area energy plan for the Isle of Dogs, South Poplar and Leaside records that the area contains several heat networks powered by gas combined heat and power engines supplying approximately 4% of the area's heat, that the largest of them serves the Barkantine Estate and is owned by the council, and that two other significant schemes are operated by E.ON at the Blackwall Reach and Aberfeldy Village developments. The same plan records that in that area the gas network supplies approximately 65% of properties while the other 35% use electricity for heating, including both heat pumps and older resistance heating.
If your whole block loses heat and hot water at once, the useful thing an engineer can do at 11pm is establish whether the fault sits in your heat interface unit and your own pipework, which we can repair, or upstream in the energy centre or the block distribution, which we cannot, and then put that finding in writing so the operator or the managing agent has something dated to act on.
Licensed across the whole borough, and hard water in every supply zone
Tower Hamlets licenses HMOs everywhere. The additional licensing designation was made on 25 October 2023, came into force on 1 April 2024 and ceases to have effect on 31 March 2029, and applies to the entire district of the London Borough of Tower Hamlets. It catches all properties, including flats, occupied by three or more persons comprising two or more households, irrespective of the number of storeys, and includes section 257 HMOs, meaning flats converted before 1991 without building control approval. Separately, a selective licensing designation covering the pre-2014 Weavers, Whitechapel and Spitalfields and Banglatown wards came into force on 1 October 2021 and runs to 1 October 2026.
The published licence conditions themselves cover gas, electrics, fire and management rather than plumbing, but the council's property standards are explicit. A fixed heating system must be provided to all lets, radiators must be fitted with thermostatic valves, and fixed storage heaters are preferred where there is no gas supply, which given the borough's electricity share is a live instruction rather than a footnote. Every bath, shower and wash hand basin must have an adequate and continuous supply of hot and cold water and be connected to the drainage system in compliance with current Building Regulations. Rooms containing baths, showers, WCs and wash hand basins must be adequately lit, ventilated and heated. Where there is a self-contained flat it must have its own exclusive supply of electricity, gas and water. On top of that, the HMO management regulations require the manager to keep water supply and drainage in proper working order and fit covers to all water tanks. Operating without a licence, or breaching a condition, can attract a financial penalty of up to £40,000 for each condition breached.
The water itself is the other constant. Thames Water publishes hardness by supply zone, and every zone covering this borough sits in its hard band. On its 2026 water quality reports, covering sampling from 1 January to 31 December 2025, the Isle of Dogs South zone averaged 261 mg/l of calcium carbonate across a range of 228 to 289, the Poplar zone averaged 272 across 252 to 285, the Bromley by Bow zone averaged 269 across 252 to 281, the Stepney zone averaged 270 across 262 to 278 and the City zone, which covers Wapping, averaged 266 across 247 to 281. Thames Water classes 200 to 300 mg/l as hard.
At those levels calcium carbonate deposits continuously on immersion elements, cylinder coils, heat exchangers, heat interface unit plates and thermostatic shower cartridges. In a borough where so much of the hot water comes from electric elements and HIU plate exchangers rather than from a gas boiler, scale does not just reduce efficiency, it is usually the thing that killed the component. That is why on a repeat hot water fault here we test for scale before quoting a third replacement of the same part.
What actually fails in Tower Hamlets property types
The borough runs from Georgian terraces in Spitalfields to forty-storey towers on the Isle of Dogs. These are the failures each of them generates.
Labour is £90/hr on weekdays and £120/hr out of hours, billed in 15-minute increments, with a fixed written price agreed after diagnosis and before the repair starts. Full rates are published on our pricing page.
Getting a van to your door in Tower Hamlets
This borough is easier to drive into than central London and harder to park in than most of east London, and a good deal of it is not council land at all. Here is what actually governs the approach.
Four parent zones, sixteen mini zones, and no zone running around the clock
Tower Hamlets states that the borough currently has 16 mini parking zones but that the zonal use of those restrictions is changing back to four main parent controlled parking zones: A around Bethnal Green, B around Bow, C around Shadwell and Stepney, and D around Poplar and Crossharbour. The hours are genuinely varied. Most sub-zones run Monday to Friday 8.30am to 5.30pm, A3 and B1 run Monday to Saturday, A6 runs Monday to Sunday 8.30am to 10pm in resident bays on streets west of Brick Lane, and A5 is close to continuous through the week. B4 adds event day Sunday controls. The council also notes that on public holidays the controls on parking bays do not apply, and that you can park on a single yellow line in a CPZ outside the restricted hours.
A lot of Tower Hamlets is not public highway
The council is unusually direct about this: parking in Tower Hamlets is not just about parking on public roads, there are numerous other areas that are not under the control of the council, and its restrictions apply only to public roads, with other restrictions applying to private land and streets such as council estates. In practice that covers a great deal of the Isle of Dogs and Canary Wharf, plus most estate roads. It is the single most common reason an engineer arrives and cannot get the van near the building, so when you call, tell us whether the address sits on an estate or a private estate road.
Suspensions and dispensations, when the job needs the kerb
Where a repair genuinely needs the space, the council's published charges from 1 June 2026 are a non-refundable bay suspension administration charge of £137.50 plus £66 per bay per day, with a supplementary emergency surcharge of £137.50. A dispensation costs £135 administration for businesses and companies plus £65 per space per day. A works or contractor permit runs from £1,080 to £1,544 a year by emissions band. None of that can be arranged at 3am, which is exactly why an emergency visit and a scheduled permanent repair are two different appointments here.
Almost all of the borough is outside the Congestion Charge
Tower Hamlets sits outside the Congestion Charge zone almost everywhere, including Canary Wharf and Whitechapel, but not quite everywhere: TfL's own postcode checker returns addresses in Spitalfields, on the western edge of the borough, as inside the zone. TfL publishes no written description of the boundary, so a specific address should be checked with its checker rather than assumed. The charge is £18 a day, or £21 if paid by midnight on the third day after travel, 07:00 to 18:00 Monday to Friday and 12:00 to 18:00 at weekends and on bank holidays. ULEZ operates across all London boroughs and the City of London at £12.50 a day for non-compliant vehicles. The Blackwall and Silvertown tunnels carry their own charge from 06:00 to 22:00 every day except Christmas Day, which matters on a Greenwich or Newham crossing. All of it is inside our rate.
Concierge desks, riser cupboards and out-of-hours keys
In a managed block the quickest route to the fault runs through the concierge or the building manager rather than the front door. When you call, tell us the building name, whether there is 24-hour cover, and whether anyone on site can open a riser cupboard or a plant room at night. If the valve we need is behind a locked door with no key holder, we will say what we can and cannot achieve before setting off rather than after arriving.

Tower Hamlets plumbing questions we get asked
There is no boiler anywhere in my flat. Who fixes the hot water?
We do, and it is the most common version of this call in the borough. 28.1% of Tower Hamlets households heat with electricity only, the third highest share of any local authority in England behind the Isles of Scilly and the City of London, a further 8.3% are on a district or communal heat network only and 3.1% have no central heating at all. Only 48.4% run on mains gas alone. Those electric homes rely on immersion heaters, vented and unvented cylinders and electric showers, and heat network homes rely on a heat interface unit rather than a boiler. Our engineers hold G3 qualifications for unvented cylinders and carry elements, thermostats, expansion vessels and TP valves as van stock, so most of these are cleared on the first visit.
Water is coming through my ceiling and I live on the sixth floor of a tower. What now?
Turn off the electricity to any affected circuit at the consumer unit, put something under the water, and call us. 80.7% of Tower Hamlets homes are in a purpose-built block, the highest share of any local authority in England other than the City of London, and in a tall block the fault is very often several floors above you on a communal riser rather than in the flat directly overhead. The valve that stops it is usually in a riser cupboard on a corridor, not under anyone's sink, so the first job is getting to the right isolation point. We attend, isolate, contain, then document exactly where the failure was so the repair sits with whoever owns that section.
How hard is the water here, and is that why my shower keeps failing?
Hard everywhere in the borough, and yes, usually. Thames Water publishes hardness by supply zone, and its 2026 reports covering sampling from January to December 2025 give average calcium carbonate of 261 mg/l in the Isle of Dogs South zone, 272 mg/l in Poplar, 270 mg/l in Stepney, 269 mg/l in Bromley by Bow, 269 mg/l in Globe Town, 266 mg/l in the City zone covering Wapping and 264 mg/l in Bow. Thames Water classes 200 to 300 mg/l as hard. At those levels scale builds continuously on immersion elements, cylinder coils, heat interface unit plates and thermostatic shower cartridges, which is why a component that fails, gets replaced and fails again on the same timeline is almost always a scale problem rather than a bad part. We test for it before quoting the same replacement twice.
I let a flat in Tower Hamlets. Do I need a licence?
Very likely. The additional HMO licensing designation was made on 25 October 2023, came into force on 1 April 2024, runs to 31 March 2029, and applies to the entire district of the borough. It covers all properties including flats occupied by three or more persons comprising two or more households, irrespective of the number of storeys, and includes section 257 HMOs, meaning flats converted before 1991 without building control approval. A separate selective licensing designation covering the pre-2014 Weavers, Whitechapel and Spitalfields and Banglatown wards came into force on 1 October 2021 and runs to 1 October 2026. The council's property standards require a fixed heating system in all lets with thermostatic radiator valves, and an adequate and continuous supply of hot and cold water to every bath, shower and wash hand basin connected to drainage in compliance with Building Regulations. Breaching a condition can attract a financial penalty of up to £40,000 for each condition breached.
My whole scheme has lost heating and hot water. Can you fix that?
Sometimes, and establishing which it is comes first. The council's own local area energy plan for the Isle of Dogs, South Poplar and Leaside records several heat networks in that area supplying about 4% of its heat, with the largest serving the Barkantine Estate and owned by the council, and further schemes operated by E.ON at Blackwall Reach and Aberfeldy Village. If the failure is in the energy centre or the buried distribution, it is the operator's repair and no plumber can fix it from inside your flat. If it is your heat interface unit, its plate exchanger, your controls or your own pipework, we clear it on the visit. Either way you get a written report naming what failed and where.
Do I have to pay the Congestion Charge on a Tower Hamlets job?
No, and in most of the borough it does not even apply. TfL's postcode checker returns Canary Wharf and Whitechapel addresses as outside the Congestion Charge zone, while addresses in Spitalfields on the western edge come back as inside it. TfL publishes no written description of the boundary, so a specific address is worth checking with its own tool. Either way the cost sits inside our labour rates of £90/hr weekday and £120/hr out of hours, along with ULEZ at £12.50 a day for non-compliant vehicles across every London borough and the Blackwall and Silvertown tunnel charges that apply 06:00 to 22:00 daily except Christmas Day. You get a fixed written price after diagnosis and no charging zone line on the invoice.
