Extract fan repair in Blackheath, done properly
If an extract fan in Blackheath is struggling or has stopped, we find the cause and quote a fixed price to repair or replace it. For a fan that fails during service, there’s a 24/7 emergency callout. The work covers fan motors, roof and wall fans and kitchen extract fans, and the jobs we see most are a worn or slipping fan belt and a fan that won’t start at all.
A callout to a small place like Blackheath goes better when we know what we are looking at: a photo of the fan, the details on its label and the access arrangements help us plan.
A written report with photos follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of extract fan repair
Every site gets its own quote. These are the things that affect it:
- Any permits to work or inductions
- The condition we find in the survey
- The number of sites or systems
- The size of the system
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or send us an email.
Managing agents and facilities teams in Blackheath
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
How it works
Every visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and leave you the report. The visit itself takes part of a day for most faults, with a return visit if parts have to be ordered. In a small place like Blackheath, the journey is planned ahead and the visit arranged around the site’s hours.
- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or send us an email.
Related advice
Different parts, different methods
Roof and wall-mounted fans
An external fan faces the weather as well as the grease. Rust on fixings and housings is a frequent find.
Fan controls
Controls are checked as well as the fan itself, because a fan that won’t start isn’t always a failed motor.
Common problems we fix in Blackheath
Some faults are in the controls rather than the fan. A failed speed controller or a wiring fault can stop a fan, and a fan that will not start isn’t always a dead motor.
It’s time to book a visit if you see:
- An overheating extract motor
- An extract fan that rattles or knocks
- A fan running too slowly to clear the kitchen
- A dead fan motor
If you run a café or takeaway near Chilworth station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

What extract fan repair looks like in Blackheath
Blackheath is about 27 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Food hygiene inspections in Blackheath are the job of Waverley council’s environmental health team. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
A fan that rarely runs, like one in a hall kitchen near Church of St Martin or elsewhere in Blackheath, can seize between uses. Holidays are the time to replace a tired kitchen fan at schools such as Chilworth CofE (Aided) Infant School, rather than mid-term.
Blackheath is about 4 miles south-east of Guildford, in Surrey. Whether your site is in the middle of Blackheath or further out, extract fan repair is available to all kinds of commercial premises, from small sites to large estates. Our Surrey coverage runs to 395 places, Blackheath among them.
Every address in GU4 is within our area for extract fan repair, from the main roads to the quietest streets. If your site is just outside Blackheath, we cover Chilworth (1 mile north-west), East Shalford (2 miles north-west), Shalford (2 miles west), Broadford (2 miles west) and Peasmarsh (3 miles west).

The countryside around Blackheath includes St Martha's Hill and St Martha's Hill and Colyer's Hanger.
When something else is needed
Extract fan repair cannot fix everything, and we’ll tell you before we start. It does not solve:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Grease build-up in the rest of the extract system
- A system that needs redesigning rather than repairing
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think before you book.
Parts of the system we cover
- Bearings
- Fan motors
- Belts and pulleys
- Kitchen extract fans
- Roof and wall fans
- Fan housings
Why deal with it now?
Weak extraction leaves heat, smoke and fumes in the kitchen. The kitchen becomes an uncomfortable place to work and grease has more chance to settle on surfaces and in the duct. It’s worth booking a check, because nobody sees inside a duct day to day.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Why us?
- Out-of-hours work and a 24/7 emergency line
- Survey first, then a fixed quote
- One number for every site across the South East and London
- Ventilation hygiene specialists since 2009
