Gas Fitting Tips for London
London Gas Safe engineers charge 25–40% more than the national UK average — always confirm whether the quote includes parts and VAT before accepting.
Central London properties often have complex condensate pipework routing requirements for new boiler installations — these can add £200–£400 to a standard quote.

Gas Fitting in London — What to Know
Licensed fitters only
All gas work in London must be performed by a licensed gas fitter. Verify your fitter's licence on the relevant state register before work begins — never accept unlicensed gas work regardless of the apparent saving.
Always get a compliance certificate
A gas compliance certificate must be issued after all gas work. Request it on completion and retain it for your property records — it is required at property sale, tenancy commencement and for insurance purposes in London.
Bundle work to reduce callout costs
Most gas fitters in London charge a callout fee that makes single small jobs expensive. Bundling multiple gas tasks — appliance connection, BBQ point, compliance certificate — in one visit reduces the effective per-item cost significantly.
What Changes Gas Fitting Prices in London?
Pipework complexity and access in London
The biggest pricing variable for gas fitting in London is pipework complexity — whether appliances can connect to existing nearby pipework, or whether new runs through walls, floors or ceilings are required. Confirm the run route with your gas fitter before accepting a quote.
Appliance type and compliance requirements
Simple bayonet point connections and cooktop installations are at the affordable end. Gas log fires, hot water systems and complete heating installations are more complex and involve additional compliance requirements. All gas work requires a compliance certificate on completion.
Property type and access conditions in London
Ground-floor homes with accessible wall cavities are the most straightforward to work on in London. Apartments, strata buildings and heritage properties add access complexity and sometimes additional approval requirements that affect scheduling and total cost.
Gas type: natural gas vs LPG
Confirm whether your London property has reticulated natural gas or LPG before requesting quotes. Appliance settings, pressure requirements and regulatory procedures differ between the two gas types, and conversion between them requires additional jet changes and compliance documentation.

You need one when selling a property, starting a new tenancy, or after any gas work is performed. Always request a compliance certificate on completion of any gas fitting work.

Verify the fitter holds a current gas fitting licence for your state or territory, confirm they will obtain any required permits, ask whether a compliance certificate will be issued on completion, and get a written quote specifying the full scope including what is and is not included.
