Gas Safety Certificate in Edinburgh

Scotland Gas Networks (SGN) manages Edinburgh's gas distribution network and is actively replacing older metallic pipes with new plastic alternatives across the city. Recent SGN works highlight areas of the network where ageing infrastructure has caused repeated gas leak incidents. Telford Road in north Edinburgh required a full upgrade programme starting January 2026 due to multiple leaks. Gorgie Road in west Edinburgh underwent the same treatment from June 2025. Old Dalkeith Road required urgent repairs in February 2026.

While SGN is responsible for the gas distribution network up to and including the gas meter, the internal gas installation within your property - all pipework, appliances, and flues beyond the meter - is the property owner's and landlord's responsibility. A CP12 inspection covers the internal installation only. Where our engineers identify a supply-side pressure issue that may indicate a fault in the SGN network, we note this in our report and advise you to contact the SGN emergency line.

Edinburgh's fatal house explosion in Baberton Mains Avenue in December 2023 was attributed to gas from an internal installation rather than the main distribution network. This underscores the critical importance of the annual CP12 inspection as a safety check on the internal gas systems that SGN's network upgrades do not cover.

A CP12 inspection covers every gas appliance, flue, and gas fitting in the property. Our Gas Safe registered engineers follow a structured HSE-aligned checklist, testing each appliance for safe combustion, adequate ventilation, and flue integrity, and pressure testing the supply pipework for leaks. The certificate records every appliance inspected, its compliance status, and the engineer's Gas Safe registration number.

• Gas boiler - operation, heat exchanger condition, flue flow rate, and flue emission sampling
• Gas supply pipework - full pressure test and visual inspection of all accessible runs
• Gas hob and oven - burner ignition, flame stability, and adequate kitchen ventilation
• Gas fires and back boilers - combustion performance, flue draw test, and spillage check
• Flues and chimneys - blockage check, liner integrity, and termination point assessment
• Ventilation openings - confirming adequate air supply for each combustion appliance
• Emergency control valve - accessible, clearly labelled, and functional
• Carbon monoxide detectors - presence noted on inspection record

Edinburgh's high proportion of tenement flats and sandstone properties introduces specific inspection considerations. Many Edinburgh tenements retain original chimney stacks and flue channels that have been adapted over decades for gas appliances. Where a gas fire is installed in an original sandstone chimney breast, our engineers carry out a flue draw test to verify that combustion gases are exiting via the flue rather than spilling back into the room.

Where a gas appliance fails the inspection, we classify it as 'At Risk' or 'Immediately Dangerous'. An Immediately Dangerous appliance is disconnected at source and must not be used until repaired and re-inspected by a Gas Safe registered engineer. We cannot issue a full CP12 certificate against a failed appliance, but we issue a full written record of every finding so your repair contractor has the exact information needed to complete the remedial work.

Edinburgh's housing stock is dominated by tenement flats. Local authority stock data indicates that 81% of council-owned Edinburgh properties are flats, with tenement flats representing 51% of that stock. Across the city as a whole, the tenement form - four to six-storey sandstone blocks with shared stairwells and multiple self-contained flats per floor - defines the residential character of areas including New Town, Old Town, Marchmont, Bruntsfield, Morningside, Leith, and Gorgie.

Tenement properties present specific gas safety considerations. Shared flues serving multiple flats in a stack, original chimney stacks serving gas fires on multiple floors, and complex pipework routing through shared infrastructure all require careful assessment. The City of Edinburgh Council's Shared Repairs Service identifies unsafe chimney stacks as a recurring issue in older, mixed-tenure tenement blocks, alongside loose masonry and roof defects. Where a gas appliance relies on a shared chimney stack or flue channel, our engineers assess the condition and draw performance of that flue as part of the inspection.

Edinburgh has 50 designated conservation areas, including the Old Town, New Town, Leith, Stockbridge Colonies, Morningside, Corstorphine, and Portobello. The city also has over 4,500 listed buildings, with approximately 900 classified as Category A - nearly 25% of all Category A listed buildings in Scotland. In these properties, any alterations to gas installations require additional care to comply with listed building consent requirements. Our engineers are familiar with the constraints that apply to gas appliance installation and flue routing in these protected properties.

Edinburgh's private rental market is large and active. The city's second-largest-in-the-UK financial services sector - with employers including Standard Life, Royal Bank of Scotland, and Baillie Gifford - combined with the University of Edinburgh and Heriot-Watt University, generates consistent rental demand across all property types. Private rents in the Lothian area averaged £1,422 per month in January 2026, and demand is particularly strong for one-bedroom properties, with 89% of one-bed lettings completing within a month in Q4 2024.

Every Edinburgh landlord with a gas supply in their rental property must hold a current CP12. In Scotland, this obligation is reinforced by the Repairing Standard, the minimum condition landlords must maintain. The Repairing Standard explicitly requires that gas and electrical installations and appliances meet safety standards, and a current CP12 is the documentary evidence that the gas installation is safe.

Edinburgh also has a higher proportion of short-term lets than most UK cities, driven by its major festival events. Properties let on a short-term basis for more than a set number of nights require a short-term let licence from the City of Edinburgh Council, and gas safety compliance is a condition of that licence. Our CP12 certificates cover both long-term and short-term let requirements, and we keep records on our system so you can retrieve certificates at short notice for licensing applications.

• Standard assured tenancies - CP12 renewed annually, copy to tenant before moving in
• Student HMO properties - all appliances in all units inspected and recorded
• Short-term lets - gas safety compliance required for Edinburgh City Council licence
• Festival Fringe lets - annual CP12 required regardless of let duration
• Portfolio landlords across EH postcodes - coordinated scheduling available

Edinburgh continues to see significant new residential development, with active sites across the city from EH5 (Granton) to EH17 (Gilmerton). Barratt Homes is active at Gilmerton Heights (EH17, from £341,995), Tower Street at Merchant Quay in Leith (EH6, from £379,995), and as part of the West Craigs development on Turnhouse Road (EH12). Cala Homes is also building at West Craigs, with homes from £294,995. Cruden Homes' West Craigs Green offers apartments from £223,500 in EH12.

New build properties purchased as buy-to-let investments must have a CP12 completed before the first tenancy begins, even though the property is new. Modern condensing combi boilers are standard across all new Edinburgh developments, and they are straightforward to inspect and certify. However, the legal requirement to hold a current CP12 is the same for a brand-new flat in Granton as it is for a Victorian tenement in Marchmont.

We can arrange first-inspection CP12 certificates for new-build Edinburgh buy-to-let properties, timed to be completed before the first tenancy start date. The certificate is issued digitally the same day, giving you and your letting agent the documentation needed before keys are handed over to the first tenant.

Edinburgh faces flood risks from multiple sources. The Water of Leith passes through the city and poses a fluvial flood risk to properties in the Murrayfield, Roseburn, and Gogar Burn areas. The Firth of Forth introduces a coastal flood risk to Leith, Portobello, and the Granton waterfront, which is being actively developed for new residential use. Surface water flooding affects low-lying and heavily urbanised parts of the city. The Scottish Environment Protection Agency (SEPA) publishes flood maps that identify at-risk areas.

Properties in flood risk areas face a specific gas safety consideration: pipework in lower ground-floor spaces or underfloor voids can be affected by water ingress during flood events, potentially damaging joints or accelerating corrosion. After any significant flood event, we recommend a gas safety inspection of the internal installation to confirm the pipework and appliances remain safe before the gas supply is restored. This is separate from the annual CP12 renewal but uses the same inspection methodology.

Edinburgh's coastline is also subject to increasing erosion pressures as sea levels rise, with an estimated £1.2 billion of Scotland's buildings and infrastructure potentially at risk by 2050. For coastal Edinburgh properties in Portobello and Granton - including newer residential developments at the Granton waterfront - the combination of coastal risk and new gas installations warrants particular attention to long-term maintenance of both internal gas systems and the distribution network serving those areas.
