Commercial sites we cover in Cambridge
Cambridge has an unusual mix of historic college and church buildings, modern science and business parks, laboratories, hotels, schools and a large hospital campus. We work on science and business parks, offices, schools, hotels, churches and historic buildings, including sites on Cambridge Science Park, Cambridge Business Park, St John's Innovation Park and the city-centre office and college buildings.
Cambridge's mix of labs, offices and historic buildings means inspection records often cover several different appliance types on one site.
We reach Cambridge from Clare via Haverhill and the A1307, and the A14 and M11 get us round the science and business parks. A team of over 10 local engineers to call on covers Cambridge and nearby Saffron Walden, Haverhill, Newmarket.
Typical sites: schools, care homes, offices, hotels, pubs & restaurants, factories & warehouses, churches & community halls and buildings run by commercial landlords & managing agents.

Gas tightness testing in Cambridge
A tightness test confirms that the gas pipework between the meter and the appliances is not leaking. On commercial sites it is carried out to IGEM/UP/1, or IGEM/UP/1A for smaller installations, with the pipework volume worked out first so the test runs for the right length of time.
We carry out a tightness test as part of every commercial gas safety inspection. You also need one:
- after a new boiler, water heater or other gas appliance is connected;
- after a gas meter is fitted, moved or exchanged;
- after any work that opens up the installation pipework;
- when gas has been smelt and the supply has been isolated, before it is turned back on.
If the test fails, we trace the leak, make the installation safe and give you a price to repair it. The result goes on your written record so your landlord, insurer or managing agent can see the pipework was tested.
Inspecting labs, colleges and historic buildings
Science and research buildings. Laboratory and research buildings often have gas interlocks, ventilation proving and strict access rules. We check that interlocks shut the gas off when ventilation fails, work under the site's permit-to-work system and keep shutdowns short so experiments and equipment are not disturbed.
Colleges, churches and older buildings. Boilers in historic buildings are often in basements, cellars or converted rooms with long flue runs through old chimneys. We pay close attention to ventilation that has been blocked up to stop draughts, flue routes that are hard to see and older appliances that may be reaching the end of their life.
Hotels, schools and care homes. Hot water and heating can't be off for long, so we inspect one appliance at a time where possible and agree times with you in advance, such as early mornings, weekends or school holidays.
Multi-let offices. We can inspect shared plant for the landlord or managing agent and keep a separate record for each tenancy where appliances belong to tenants.
What happens on the day
- Before the visit you send the site address, a list of appliances if you have one, and any access or induction rules.
- On arrival the engineer signs in, agrees which appliances will be turned off and for how long, and finds the meter and emergency control valve.
- The tightness test is carried out on the installation pipework.
- Each appliance is checked in turn: gas pressure, heat input, combustion, flue, ventilation and safety devices.
- Before leaving the engineer puts everything back into service and talks you through anything found.
- You receive the written record by email, listing every appliance, the results and any defects with priced remedies.
Most sites book the inspection every 12 months, and many combine it with the annual boiler service in Cambridge so there is only one visit. If a boiler has already broken down, see commercial boiler repair in Cambridge or call 0800 0996 007. If you smell gas, leave the building and call the National Gas Emergency Service on 0800 111 999 first.
Keeping your records in order
The Gas Safety (Installation and Use) Regulations 1998 require whoever is in control of non-domestic premises to keep gas appliances, flues and pipework safe. A written record from a Gas Safe registered engineer, renewed every year, is the usual way to show you are doing this, and insurers, landlords and auditors often ask to see it. Our work is carried out under Gas Safe registration 985448, and our engineers are OFTEC trained for oil-fired plant on sites that also have oil boilers.
Keep each year's record with your building logbook, along with any repair reports. If a defect was found, keep the record of the repair too, so anyone checking can see it was put right.
Who needs a commercial gas safety check in Cambridge
The Gas Safety (Installation and Use) Regulations put a duty on employers and anyone in control of commercial premises to keep gas appliances, flues and pipework safe. In Cambridge these are the sites that book us most:
- Colleges, universities and research institutes with basement boiler rooms, long historic flues and strict access rules.
- Science and business parks where shared plant serves labs, clean rooms and multi-let offices.
- Hotels, pubs and restaurants with gas ranges, fryers and a kitchen gas interlock.
- Schools, care homes and churches whose insurers ask for up-to-date written records every year.
- Commercial landlords and managing agents who need proof that shared boilers and water heaters have been checked for each tenancy.
If you are unsure whether your building counts as non-domestic, tell us the use class and we will confirm before we quote.
Common faults we find in Cambridge plant rooms
- Ventilation openings blocked to stop draughts in older college and church cellars, covered in our plant room ventilation guide.
- Flue joints that have parted inside long brick chimneys, a carbon monoxide risk explained in our kitchen flue safety guide.
- Kitchen or lab interlocks bypassed, or not linked to the extract fan or ventilation proving.
- Unlabelled or unsupported gas pipework after past alterations in multi-let offices.
- Boilers with poor combustion readings that need a service, which we can book as commercial boiler servicing in Cambridge.
Our plant room safety checklist lists simple checks your own staff can make between visits, and our gas tightness testing guide explains when a retest is needed after work on the pipework.
Planning the visit around Cambridge sites
Science parks and college sites often need permits, inductions or out-of-hours access. Tell us about parking, key-holder details and any blackout times when we quote, and we will plan the isolation windows around your operations. A team of over 10 local engineers covers Cambridge from our base at CO10 8NN via the A1307, A14 and M11.
All gas work is carried out under Gas Safe registration 985448. You can confirm the details yourself using our guide to checking a commercial gas engineer's qualifications. Call 0800 0996 007 or WhatsApp 07947 578332 to book.
Questions we get asked
Can you issue a commercial gas safety certificate in Cambridge?
Yes. After the inspection you receive a written commercial gas safety record listing each appliance, the readings taken, the result and any defects, with a priced remedy for anything that needs work.
Is it the same as a domestic landlord CP12?
No. The domestic landlord certificate applies to let homes. Ours covers commercial boiler rooms and commercial gas appliances; many people still call it a commercial CP12.
What if something fails?
We make it safe under the Gas Industry Unsafe Situations Procedure, explain the risk in writing and give you a price to fix it. Where we can, we agree the repair while we are still on site.
Do you cover the Cambridge science and business parks?
Yes: the Science Park, Cambridge Business Park, St John's Innovation Park and the city centre, plus offices and units on the edge of the city.
Do you carry out gas tightness testing in Cambridge?
Yes. A tightness test checks the installation pipework for leaks, and on commercial sites it is carried out to IGEM/UP/1, or IGEM/UP/1A for smaller installations. We test as part of the inspection, and after any work that breaks into the gas supply, such as a new appliance or a meter change.
How long does an inspection take?
It depends on how many appliances there are and how easy they are to reach. A plant room with one or two boilers is usually done in a morning, while a site with boilers, water heaters and heaters spread across several buildings can take a full day. We give you an estimate when we quote.
Who is responsible for the inspection, the landlord or the tenant?
It depends on the lease. Under the Gas Safety (Installation and Use) Regulations 1998, whoever is in control of the premises or the appliances must keep them safe, and in a multi-let building the landlord or managing agent usually looks after shared plant while tenants look after their own appliances. If the lease is unclear, ask your agent, and we can inspect for either party.
Can you inspect gas appliances in a laboratory or research building?
Yes, for the boilers, water heaters and heating plant that serve the building. We check gas interlocks and ventilation proving where they are fitted, and we work around the site's permit-to-work and induction rules.
Do you inspect gas in homes or student houses?
No. Fast Commercial Boiler Help only works on commercial and non-domestic gas, such as offices, schools, colleges, care homes, hotels, churches, halls and industrial units. Domestic landlord certificates for let houses and flats are outside what we do.
How often does a Cambridge commercial site need a gas safety check?
Most insurers, landlords and facilities teams work to an annual check of boilers, pipework and appliances. Busy commercial kitchens, older college plant rooms and sites with many appliances are often checked more often, and your insurer or lease may set its own interval.
Can you inspect our kitchen and boiler plant on the same visit?
Yes. We can check the boiler plant, catering appliances, gas interlock, ventilation and pipework on the same visit, so you get one set of records for hotels, pubs, restaurants and college catering sites across Cambridge.
Do you need to shut the gas off during the inspection?
Some tests, such as a tightness test, need the supply isolated for a short time. We agree the timing with you first so labs, hotels, schools and offices can keep critical equipment running.
Can you inspect oil or LPG boilers on the same Cambridge site?
Yes. Our engineers are OFTEC trained for oil-fired plant and also work on LPG. Oil plant is checked by OFTEC trained engineers rather than a gas safety record, which suits mixed fuel sites on the edge of the city.
Do you cover Addenbrooke's and the Biomedical Campus area?
Yes. We cover commercial plant around the Biomedical Campus, Trumpington, Cherry Hinton and the southern science parks, working to site access and induction rules where they apply.
