Water Conservation

4 options

Free water-saving home visit and devices — Thames Water Smarter Home Visits

citywide

Thames Water, delivered in partnership with Groundwork London, offers a free in-home visit that fits water-saving devices and checks for leaks in toilets, taps and plumbing.

  • Free for Thames Water customers, delivered by Groundwork London on Thames Water's behalf
  • Free devices fitted on the spot, such as tap aerators and cistern devices, to cut water use immediately
  • Visit includes a leak check on toilets, taps and visible plumbing
  • Book by calling 0800 622 6623 or emailing london.shv@groundwork.org.uk
  • Applies uniformly across Thames Water's whole supply territory, which spans all London boroughs it serves plus areas outside London (Surrey, Berkshire, Oxfordshire, Wiltshire, Gloucestershire) — not organized by borough

Free smart water meter installation — Thames Water

citywide

Thames Water is installing smart water meters at no cost across its London network, letting residents track daily usage and catch leaks before they inflate bills.

  • Over 1.2 million smart meters installed across the Thames Water region to date, in partnership with Arqiva
  • Around 2 million customers are already metered; the utility expects most customers to be metered by 2030
  • Installation is free and scheduled directly by Thames Water
  • Metered customers can view daily usage online, which is the main tool for spotting hidden leaks
  • Rollout is scheduled by Thames Water's own network logic, not by London borough — no borough-level installation data is published

2026 Temporary Use Ban (hosepipe ban) — what London households can and can't do

citywide

Thames Water's current Temporary Use Ban restricts hosepipe use across its entire supply area, including all London boroughs it serves, following a record dry spring and summer.

  • Restrictions took effect at 00:01 BST on 23 July 2026 across the whole Thames Water supply area
  • Hosepipe use for cars, gardens, and paddling pools is banned; buckets and watering cans are still allowed
  • Exemptions apply for health/safety needs and customers with mobility needs
  • Breaching the ban can result in a fine of up to £1,000
  • Bans follow supply-area boundaries, not London boroughs — an earlier 2025 ban applied only to Swindon, Gloucestershire, Oxfordshire, Berkshire and Wiltshire and explicitly excluded London, showing the ban's footprint can shift between London and non-London areas from one ban to the next

Priority Services Register — free extra support during water emergencies

citywide

Thames Water's free Priority Services Register gives extra support (bottled water during interruptions, easier-read bills, a dedicated contact) to customers with disabilities, health conditions, or other vulnerabilities.

  • Free to join; covers disabilities, chronic health conditions, dementia, mobility constraints, and households with a child under five
  • Provides bottled water during supply interruptions such as bursts or ban-related restrictions
  • Gives a dedicated support phone number and priority contact during emergencies
  • Can be registered by the customer or by a carer/family member on their behalf
  • Sign up free via 0800 009 3652 or the Thames Water Priority Services site — identical process regardless of which London borough you live in

Home Weatherization

5 options

ECO4 free home retrofit — Waltham Forest LA Flex eligibility (~55% of homes)

Borough: Waltham Forest

borough-specific

ECO4 offers up to £30,000 of free insulation, heating and solar upgrades, and Waltham Forest's own Local Authority Flexible Eligibility (LA Flex) rules make an estimated 55% of homes in the borough eligible — one of the highest rates in London.

  • ECO4 funds up to £30,000 of free insulation, heating, and solar improvements; the national scheme closes December 2026
  • Waltham Forest's own LA Flex criteria, set locally on top of the national qualifying-benefits route, extend eligibility to an estimated 55% of homes in the borough
  • Applies to homes with an EPC rating of D, E, F, or G
  • Apply via an accredited ECO4 installer, or check Waltham Forest Council's LA Flex referral route directly

ECO4 free home retrofit — Ealing LA Flex eligibility (~15% of homes)

Borough: Ealing

borough-specific

The same ECO4 scheme applies nationally, but Ealing's LA Flex criteria are considerably tighter than Waltham Forest's — only an estimated 15% of homes qualify, showing how sharply ECO4 access depends on which council you live under.

  • Same national ECO4 mechanism (up to £30,000, closes December 2026) as every London borough
  • Ealing's own LA Flex criteria extend eligibility to an estimated 15% of homes in the borough — far below Waltham Forest's ~55%
  • Applies to homes with an EPC rating of D, E, F, or G
  • Apply via an accredited ECO4 installer, or check Ealing Council's specific LA Flex criteria before assuming ineligibility

Warm Homes: Local Grant — up to £30,000 for lower-income and fuel-poor households

citywide

A national grant launched April 2025 to cut fuel poverty and carbon emissions, funding home improvements for lower-income households, renters, and social housing tenants.

  • Up to £30,000 of funding per household for insulation, heating and related improvements
  • Eligibility: home in England with EPC rating D, E, F or G
  • Household income usually £36,000/year or less, or living in one of the most deprived areas, or receiving a means-tested benefit
  • Eligibility rules are set nationally by income/EPC criteria, not by borough — every London borough administers the same national rules, unlike ECO4's LA Flex route

Mayor's Warmer Homes Advice Service (SHINE London)

citywide

A free, Mayor-funded energy advice service for vulnerable and low-income Londoners, helping residents work out what home-improvement grants they qualify for.

  • Free advice service, funded by the Mayor of London, has supported more than 24,000 households to date
  • Call SHINE London on 0300 555 0195 to check eligibility for grants and support
  • Helps residents navigate ECO4, LA Flex, and Warm Homes: Local Grant eligibility in one call, regardless of which borough they live in
  • Targeted at vulnerable Londoners and those on low incomes

Boiler Upgrade Scheme — £7,500 towards a heat pump

citywide

A national grant giving homeowners £7,500 towards an air source heat pump (or £5,000 for ground source) to replace a fossil-fuel boiler, available to all homeowners in England and Wales.

  • £7,500 grant towards an air source heat pump installation
  • £5,000 grant towards a ground source heat pump installation
  • Available to all homeowners in England and Wales with a valid EPC certificate — not means-tested, and not administered per-borough
  • Applied for through an accredited installer, who deducts the grant from the quoted price

Solar Rebates

3 options

Solar Together London — council-backed group-buying scheme

citywide

A free, no-obligation group-buying scheme run with London councils that uses collective bargaining to secure a lower installed price for solar panels than buying individually.

  • Now in its fifth phase; over 3,000 London homes have had solar installed through the scheme to date
  • Secures 20-30% discounts versus buying solar individually, per the Greater London Authority — one uniform discount mechanism, not a per-borough rate
  • Open to homeowners in participating council areas; most, but not necessarily all 33, London boroughs take part in any given phase — check your borough is currently participating before registering
  • Registration is free with no obligation to proceed after receiving a quote
  • Process: register, pre-vetted installers bid against each other, resident reviews the recommended offer and decides

Smart Export Guarantee (SEG) — get paid for surplus solar electricity

citywide

A government-mandated scheme requiring large electricity suppliers to pay households for solar electricity they export back to the grid.

  • Applies to any home with solar panels (and a smart meter) generating more electricity than it uses
  • 2025 supplier rates typically range 4p-15p per kWh; some tariffs pay considerably more at peak times
  • A typical 3.5kW solar array generating ~3,000 kWh/year can earn up to several hundred pounds annually depending on tariff chosen
  • Requires switching to or opting into a specific SEG tariff with a licensed supplier — set by supplier and national rules, with no borough dimension at all
  • Ofgem publishes an annual report on active SEG tariffs and payouts

0% VAT on solar panel and battery installations

citywide

A tax relief, not a cash grant, that removes VAT entirely from residential solar and battery storage installations, cutting the total project cost by 20%.

  • 0% VAT applies to solar panels installed at a UK home until 31 March 2027, under HMRC VAT Notice 708/6
  • Covers the full installed package — equipment and labour — not just hardware
  • Standalone battery storage and retrofit batteries added to an existing solar system also qualify (rule change from 1 February 2024)
  • Applied automatically by the installer on the final invoice — a national tax rule with no borough variation whatsoever
  • Rate rises to 5% from 1 April 2027

EV Charging

6 options

On-street EV chargepoint rollout — Tower Hamlets (2,000 points)

Borough: Tower Hamlets

borough-specific

Tower Hamlets partnered with Ubitricity to install 2,000 on-street residential lamppost EV chargepoints by the end of 2025 — one of the largest borough rollouts in London.

  • Target of 2,000 on-street residential chargepoints by end of 2025, delivered with Ubitricity
  • Aimed at residents without off-street parking, a large share of the borough's densely-terraced housing stock
  • Requires registration with the network and an annual fee (around £48/vehicle) to use Source London-branded points
  • Most points offer 3kW (Type 1) or 7.4kW (Type 2) charging — suited to overnight charging, not rapid charging
  • Available via TfL's own map and integrated into third-party apps such as Zap-Map

On-street EV chargepoint rollout — Bexley (400 points)

Borough: Bexley

borough-specific

Ubitricity and Bexley Council completed installation of 400 on-street residential lamppost EV chargepoints between November 2025 and March 2026 — a smaller, completed rollout compared to Tower Hamlets' larger, faster one.

  • 400 lamppost chargepoints installed across the borough, November 2025-March 2026
  • Delivered in partnership with Ubitricity, using the same lamppost-charging model as other London boroughs
  • Requires registration with the network and an annual fee (around £48/vehicle) to use Source London-branded points
  • Illustrates a mid-size, already-completed rollout, in contrast to Tower Hamlets' larger 2,000-point target and Harrow's still-in-progress rollout

On-street EV chargepoint rollout — Harrow (100+ points, in progress)

Borough: Harrow

borough-specific

Harrow began rolling out over 100 new on-street EV chargepoints in April 2025, targeting residential areas with limited off-street parking — a smaller, earlier-stage rollout than Bexley's completed 400-point scheme or Tower Hamlets' 2,000-point target.

  • Rollout began April 2025, targeting over 100 new chargepoints in residential areas with limited off-street parking
  • Installations ongoing throughout 2025-2026, unlike Bexley's already-completed 400-point rollout
  • Requires registration with the network and an annual fee (around £48/vehicle) to use Source London-branded points
  • Check Harrow Council's own EV charging page for current installation status before assuming a point is available on your street

Workplace Charging Scheme — 75% off EV chargepoints for employers

citywide

An OZEV grant covering up to 75% of the cost of installing EV chargepoints at a workplace, letting London employees charge where they park during the day.

  • Covers up to 75% of purchase and installation costs (incl. VAT), capped at £350 per socket (rising to £500 from 1 April 2026)
  • Maximum of 40 sockets across all sites per applicant business
  • Scheme extended for a final year, now closing 31 March 2027
  • In 2025, businesses redeemed 7,506 vouchers, funding 69,439 sockets nationally to date at £25.6m in grants
  • Applies to any business, charity or public sector body with off-street parking, anywhere in London — eligibility rules are national, not borough-set

EV Chargepoint Grant for renters and flat owners

citywide

A government grant covering most of the cost of installing a home EV chargepoint for Londoners who rent or own a flat with a private off-street parking space.

  • Covers 75% of cost to buy and install a socket, up to £500 (£350 if applied for before 1 April 2026)
  • Applicant must own or live in a flat, or rent any residential property, and own an eligible EV
  • Requires a private off-street parking space at the property
  • Landlord, freeholder, or managing agent permission must be obtained before applying
  • National eligibility rules apply identically in every London borough; landlords can separately claim up to 200 grants per year across their properties

ULEZ zero-emission vehicle exemption

citywide

Fully electric vehicles are 100% exempt from London's Ultra Low Emission Zone daily charge, a direct and ongoing financial incentive for EV ownership across the whole of Greater London.

  • ULEZ covers the whole of Greater London (since 2023) and operates 24/7, every day except Christmas Day — uniform across every borough by design
  • Fully electric vehicles pay £0 ULEZ charge, versus up to £12.50/day for non-compliant petrol/diesel vehicles
  • Separate from the Congestion Charge, where the EV discount ended in December 2025 — EVs now pay the Congestion Charge (with a 25% Auto Pay discount)
  • No registration needed for the ULEZ exemption itself; it applies automatically based on vehicle emissions data

Community Gardens/Allotments

5 options

Capital Growth — London's free food-growing network

citywide

A free membership network run by the charity Sustain, connecting anyone growing food in London — at home, on an allotment, or in a community garden — to discounts, advice, and events.

  • Free membership, takes about 5 minutes to join, open to over 2,000 existing members across London
  • Members get discounts, growing advice, and a monthly e-newsletter, identical regardless of which borough they live in
  • Publishes a public map of Capital Growth food-growing spaces across London
  • Runs an annual food-growing festival (Good to Grow) each April
  • Contact: capitalgrowth@sustainweb.org or via the Capital Growth website

Hackney Allotment Society waiting list

Borough: Hackney

borough-specific

The route into an allotment plot in Hackney, run by the resident allotment society rather than the council directly — a still-open, multi-year waiting list, in contrast to Lambeth's fully closed one.

  • Plot rent for 2025: £31/year for a full plot (£15.50 concession), £15.50/year for a half plot
  • £4/year admin fee to join the waiting list
  • Around 70 people were on the waiting list as of the 2025 AGM
  • Wait time is described as likely several years, varying by chosen site
  • The list is currently open to new applicants — unlike Lambeth's three allotment sites, where all waiting lists are closed

Lambeth allotments — waiting lists currently closed

Borough: Lambeth

borough-specific

Lambeth Council's allotment waiting lists across all three of its sites are closed to new applications — a starker outcome than Hackney's still-open, multi-year list, and a concrete example of how allotment access varies severely by borough.

  • 2025-26 fees range from £105 (no water) to £226 (shed and water access) per plot
  • Waiting lists for all three Lambeth allotment sites were closed to new applications as of this check
  • Borough allotment data is published via the Lambeth Data Hub
  • Illustrates that in some London boroughs there is currently no route onto a waiting list at all, not just a long wait — the opposite end of the spectrum from Hackney's open (if slow) list

The Orchard Project — community orchard planting

citywide

A charity that plants and supports community orchards on under-used urban land across London, giving residents without allotment access another way to grow food locally and build community.

  • Has planted and cared for over 720 community orchards across England, Scotland and Wales since 2009, with a strong concentration in London
  • Partners with local authorities, housing associations, schools, and community groups to find and plant sites in any borough
  • Community groups plan, plant and maintain their orchard with support from a team of expert orchardists
  • Publishes an interactive directory of existing London orchard profiles

Groundwork's Our Space Award — grants to green a community space

citywide

A Groundwork London grant of £500 to £5,000 to help residents and community groups create or improve a shared green space, including community gardens.

  • Grants range from £500 up to £5,000, with standard grants typically £2,000-£5,000
  • Non-constituted (informal) community groups are eligible to apply, not just registered charities
  • Aimed at active community participation in greening neighbourhoods across London, open to any borough
  • Apply and check current funding rounds via Groundwork's London grants page
