Renting or a council tenant? Your landlord must arrange the annual gas safety check; council tenants don’t organise their own gas-heating work — Haringey directs them to its gas-heating contractor. More under Safety first ↓.

What’s in an annual service — and how it differs from a gas safety check
An annual service is preventative: a Gas Safe engineer checks the boiler is burning cleanly and safely, inspects the seals and casing, tests the controls and pressure, examines the flue, and cleans components where needed. It catches small faults before they become breakdowns, keeps the boiler running efficiently, and is the thing that protects you against unsafe combustion and carbon monoxide. Most manufacturers’ warranties also require an annual service to stay valid, so it’s worth keeping the records.
A service is not the same as a gas safety check, though an engineer often does both in one visit. A service is maintenance; a gas safety check is a safety inspection of gas appliances, flues and pipework, and for landlords it’s a legal duty (see below) that produces a record — commonly called a CP12. If you own your home there’s no legal requirement to have either, but an annual service is sensible, and many people ask for the safety check alongside it for peace of mind.
Safety first
A boiler is a gas appliance, so these points aren’t optional.
- Smell gas or suspect a leak? Don’t touch switches or flames, open windows if safe, leave, and call the National Gas Emergency Service on 0800 111 999 from outside.1
- Carbon monoxide. A poorly maintained boiler can give off CO — fit an audible alarm marked to BS EN 50291, and treat headaches or dizziness that ease when you leave the house as a warning sign, advises the HSE. A service is one of the main ways CO risk is caught early.2
- Servicing is Gas Safe only. A gas boiler must be serviced and safety-checked by a Gas Safe registered engineer — you can check an engineer on the register.3
- Landlords. If you let the property, you must arrange a gas safety check every 12 months by a Gas Safe engineer, keep the record, and give the tenant a copy within 28 days — a duty set out in Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998.4 Separately, the repair duty for heating and hot-water installations sits in the Landlord and Tenant Act 1985.5
- Council tenants don’t arrange their own gas-heating work — as Haringey Council sets out, the council directs tenants to its gas-heating contractor for the area: K&T Heating on 020 8269 4520 for Broadwater Farm and North and South Tottenham, or Purdy on 01992 703410 for Hornsey, Wood Green and supported housing.6
Find a verified engineer by district
Servicing needs follow the housing.
West — Muswell Hill, Highgate, Crouch End, Hornsey, Fortis Green, Alexandra Park. Period homes often run older boilers that benefit most from regular servicing, and there are many converted flats whose landlords need annual gas safety checks. Council tenants in Hornsey are directed to the council’s contractor, Purdy.
Centre — Wood Green, Turnpike Lane, Bounds Green, Bowes Park, Noel Park. A lot of rented flats and conversions, so landlord gas safety checks are common alongside services; combi boilers predominate. Wood Green council tenants are directed to Purdy.
East — Tottenham, Bruce Grove, Seven Sisters, South Tottenham, West Green, St Ann’s. A dense mix of estates and conversions; council tenants are directed to Haringey’s gas-heating contractor, K&T Heating for North and South Tottenham, for gas-heating repairs rather than a private engineer.6
North-east — Tottenham Hale, Northumberland Park, White Hart Lane, Broadwater Farm. New-build flats on communal or district heating have the heat-interface unit serviced by the building’s scheme; a standalone flat boiler still needs an annual service, with access sometimes through a managing agent.
South edge — Harringay/Green Lanes, Finsbury Park, Manor House, Stroud Green. Boundary-sensitive, so confirm you’re in Haringey if you’ll need the council route; older boilers in the period stock here reward yearly attention.
What boiler servicing costs
| Servicing job | Typical Haringey range (editorial estimate) |
|---|---|
| Annual boiler service | £70 – £120 |
| Landlord gas safety check (CP12), one appliance | £60 – £90 |
| Service and safety check together | £90 – £150 |
| Each additional appliance on the safety record | £10 – £30 |
Editorial estimate only — broad indicative ranges to sense-check a quote, not regulated rates, not market data and not a published cost survey. The number of appliances and whether you combine a service with the safety check move the figure most; always confirm what’s included first.
A local factor: all of Haringey is inside the London-wide Ultra Low Emission Zone,7 and controlled parking zones can affect where an engineer parks — worth a word when you book (the Congestion Charge doesn’t reach Haringey).
Frequently asked questions
Once a year is the standard advice, and most manufacturers’ warranties require an annual service to stay valid — so keep the records.
No.
A service is preventative maintenance; a gas safety check is a safety inspection of gas appliances, flues and pipework that, for landlords, is a legal duty and produces a record — often called a CP12.
An engineer can do both in one visit, but they’re different things.
Arrange a gas safety check every 12 months by a Gas Safe engineer, keep the record, and give the tenant a copy within 28 days.
This is set out in Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998.
Gas Safety (Installation and Use) Regulations 1998 — Regulation 36
Usually — most boiler manufacturers require a documented annual service as a warranty condition, so keep the paperwork from each visit.
It can — Thames Water supplies the borough with hard water, and scale on the boiler’s hot surfaces is one of the things a service helps keep in check.
Your landlord arranges the annual gas safety check under Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998.
The Landlord and Tenant Act 1985 separately covers the repair duty for heating and hot-water installations.
Council tenants don’t organise their own — Haringey directs them to its gas-heating contractor.

A yearly service is the cheapest insurance a boiler gets — it keeps the warranty alive, the running costs down and the carbon monoxide risk caught early, and for landlords it sits alongside the annual gas safety check that’s a legal duty. Contact a verified Haringey engineer below.
