One contract for a 40-flat portfolio's CP12, EICR & TM44
The challenge
A lettings agent managing 40 flats was juggling several contractors and missing certificate renewal dates — a real risk of fines and non-compliant lets.
What we did
- Audited every property's certificate status and expiry date
- Consolidated CP12, EICR, TM44, PAT and F-Gas under one planned contract
- Set up renewal tracking with reminders ahead of every deadline
- Issued digital certificates stored centrally for instant access
“We went from chasing five contractors to one call. Nothing slips through the cracks now.”
— Lettings Director, Kensington agency
Cutting call-outs in a 120-unit block with planned FCU & HIU servicing
The challenge
A managing agent faced constant reactive breakdowns of fan coil units and heat interface units, with residents complaining about heating and cooling.
What we did
- Surveyed all plant and built an asset register
- Created a PPM schedule aligned to manufacturer guidance and usage
- Scheduled FCU filter and coil servicing plus HIU performance checks
- Logged every visit digitally with photos and recommendations
“Residents stopped complaining about heating and cooling. That's the win we needed.”
— Block Manager, Nine Elms
Strip-out to turnkey: re-letting a tired two-bed in three weeks
The challenge
A landlord's dated two-bed flat sat empty and losing rent. They needed a fast, high-quality refurbishment to re-let at a stronger price.
What we did
- Full strip-out with a single dedicated project manager and fixed price
- New kitchen and bathroom, redecoration throughout and new flooring
- Electrical and heating updates completed alongside the fit-out
- Snagging, final clean and handover with certificates
“One point of contact, a fixed price and no surprises — and it let straight away.”
— Private landlord, Islington
Same-day AC recovery for a City office, then onto a service contract
The challenge
An office lost cooling during a summer heatwave and staff could not work. They needed an urgent fix and a plan to stop it happening again.
What we did
- Attended the same day and diagnosed the fault
- Repaired and recommissioned the system to full performance
- Placed the site on a planned service contract
- Set up annual F-Gas leak checks and record-keeping
“On site within hours and back up and running the same day. Exactly what we needed.”
— Facilities Manager, City of London
Resolving heating complaints across a new-build district-heating scheme
The challenge
Residents in a new development reported inconsistent hot water and heating from their Heat Interface Units, generating a stream of complaints.
What we did
- Serviced and rebalanced HIUs across the scheme
- Checked plate heat exchangers, strainers and controls
- Corrected commissioning issues left from handover
- Set an ongoing servicing schedule for the network
“The heating complaints just stopped. The scheme runs the way it always should have.”
— Development Manager, Greenwich
Tuning BMS controls to cut a commercial building's energy use
The challenge
A commercial building's HVAC ran inefficiently with poor scheduling and little visibility of how the plant was performing.
What we did
- Reviewed the existing BMS strategy and set-points
- Optimised schedules and integrated plant controls
- Added monitoring for clear performance visibility
- Tuned comfort settings for tenants floor by floor
“Smarter controls, lower bills and warmer tenants — all from tuning what we already had.”
— Property Owner, Canary Wharf

Case Study FAQs
Common questions from landlords, agents and property managers.
Can Mainteniq provide references for property maintenance in London?+
Yes. Alongside the examples on this page we can share references relevant to your property type and borough — from single flats to managed blocks and portfolios. Just ask and we'll match you to comparable work.
Do you work on blocks and property portfolios?+
We do. Much of our work is planned maintenance for managing agents and landlords with multiple units — coordinating FCU, HIU, MVHR and compliance across a whole block or portfolio under a single contract.
Can you show before and after results for renovations?+
Yes. For refurbishment projects we document the property before work starts and at handover, so you can see the transformation and the impact on re-let speed and rent.
How do you coordinate compliance certificates across a portfolio?+
We audit every property's certificate status, put CP12, EICR, TM44, PAT and F-Gas on one planned contract, and track renewals with reminders ahead of each deadline — so nothing lapses and you get one invoice.
Do you offer planned maintenance contracts for landlords?+
Yes. Planned Preventative Maintenance (PPM) contracts reduce reactive breakdowns, spread cost predictably across the year, and keep your properties compliant and tenant-ready.
Which London areas do you cover?+
We cover London and a 120-mile radius, including Kensington & Chelsea, Westminster, Islington, Camden, Wandsworth, the City, Canary Wharf and Greenwich, plus Birmingham, Oxford, Cambridge, Brighton and Reading.
