Yes. Ofgem’s heat network regulation covers Great Britain — England, Scotland and Wales — so a Scottish block with a shared boiler is regulated in the same way as one in Bradford: existing networks were deemed authorised on 27 January 2026 and must register with Ofgem by 26 January 2027, and the same quarterly and annual data returns apply. The Scottish Government says so in its own words: “on 27 January 2026, Ofgem’s formal role as regulator of heat networks began, with the initial set of rules in place. Existing heat network operators and suppliers have been given a ‘deemed authorisation’ and have until 26 January 2027 to register with Ofgem.” Verified: Scottish Government, Heat networks policy; the Regulations are the Heat Networks (Market Framework) (Great Britain) Regulations 2025 (named in Ofgem’s authorisation conditions, definitions section).

Scotland also has its own heat networks law, the Heat Networks (Scotland) Act 2021, which deals with a different thing — licensing and consenting of networks — and its licensing regime has not started. Details below.

What is different in Scotland?

Consumer advice bodies. Ofgem’s authorisation conditions name Citizens Advice Scotland and Consumer Scotland (alongside Citizens Advice) as the “Relevant Consumer Advice Bodies”, and suppliers’ complaints procedures must signpost independent help. The Scottish Government adds that “advice and advocacy services started for consumers in April 2025. In Scotland, Consumer Scotland, Advice Direct Scotland, and Citizen’s Advice Extra Help Unit will advocate for Scottish consumers.” Verified: authorisation conditions decision, Condition 2 definitions and Condition B12; Scottish Government heat networks policy page.

The Heat Networks (Scotland) Act 2021. The Act (asp 2021/9) creates a Scottish regime for licensing heat network operators and consenting new networks. In 2024 the Scottish Government expected Ofgem to become the Scottish licensing authority. Its March 2026 consultation on an installation and maintenance licence now proposes “for the licence regulator to be either the Scottish Ministers (in which case the day-to-day work would be done by the Scottish Government), or an organisation selected by Scottish Ministers”, with Ministers to “make their decision at a future date”. Verified: Scottish Government, Heat networks installation and maintenance licence: consultation, 13 March 2026. It also expects “many existing heat networks will be too small to need or want” a licence. the Act is at legislation.gov.uk.

Licensing has not started. As of 30 October 2026 the Scottish Government describes licensing as a proposal in draft legislation, which it said it would not introduce until after the May 2026 Scottish election (Heat Networks Delivery Plan review report 2026); we found no sign it has been introduced since — the draft Buildings (Heating and Energy Performance) and Heat Networks (Scotland) Bill (November 2025) proposes “an opt in licensing regime enabling heat network developers in Scotland to access the rights and powers”. Verified: Scottish Government heat networks policy page. For an existing communal block this means: no Scottish licence to apply for today; Ofgem registration is the live obligation.

Public-sector buildings. In Scotland, “owners of non-domestic public sector buildings must produce a building assessment report for each of their buildings to check if they are suitable to connect to a heat network.” This is a public-sector duty, not one for private blocks. Verified: Scottish Government heat networks policy page.

Service charges and back-billing in Scotland

Our service-charge guide explains how Ofgem’s 12-month back-billing limit is switched off for service charges, leaving section 20B of the Landlord and Tenant Act 1985 as the clock. That Act “extends to England and Wales” (section 40), verified, and the First-tier Tribunal (Property Chamber) route is likewise English and Welsh. Scottish flats are usually run under factoring arrangements governed by separate Scottish law, and Ofgem’s conditions refer to “any equivalent, similar or analogous bodies in Wales, Scotland or Great Britain” as the dispute-resolution route. If a charge dispute is live in Scotland, get Scottish advice; the Ofgem reporting rules (report the heat element, keep the workings) are the same.

What to do if you run a block in Scotland

1. Register each network on Ofgem’s digital service by 26 January 2027 — the registration checklist applies as written.
2. Join the Energy Ombudsman scheme.
3. Start the complaints log, the debt log and the tariff or heat-element record from April 2026 — see what to report and when.
4. Keep an eye on the Scottish Bill; we will update this page if licensing commences and touches existing communal networks.

What changed on this page

30 October 2026

Re-checked. Scottish licensing updated from the Scottish Government's March 2026 licence consultation: who the licence regulator will be (Scottish Ministers or a body they select) is undecided, so the 2024 line about Ofgem becoming the licensing authority was replaced. Removed a quote the data-reporting guidance doesn't contain ('heat networks in Great Britain'). The Landlord and Tenant Act's England-and-Wales extent is now verified against the statute, and the back-billing line matches Ofgem's condition B7.3.
