What to expect
from Aveat

A partner you can trust

Delays caused by unreliable subcontractors cost time and money. With five decades of experience and a proven delivery record, our team is structured, well-resourced, and committed to hitting agreed deadlines. When we say we’ll be there, we mean it.
01

Flexibility on live construction sites

Design changes, programme adjustments, and last-minute curveballs are part of the job. We’re used to working in fast-moving settings and can adapt quickly to revised drawings, sequencing changes, and evolving site requirements.
02

Commercial awareness and cost control

We understand the importance of protecting your margins. By getting involved early and working diligently alongside all stakeholders, we can identify better solutions, streamline operations, and prevent the projects from going over budget.
03

Clear communication from start to finish

At every stage of the build, you’ll benefit from straightforward communication, proactive problem-solving, and updates as often as you need them. There won’t be any surprises – just clarity and consistency from a dependable team.
04

Shifting the focus to
renewable energy

Sustainability is now a core requirement on many projects, and mechanical systems play a major role in meeting a build’s environmental and performance targets.

Aveat supports main contractors with compliant, efficient, and future-ready mechanical solutions that align with planning conditions, client expectations, and modern building regulations.
From low-carbon heating systems and energy-efficient HVAC to renewable technologies such as air source heat pumps and smart controls, we can help you hit your sustainability targets while keeping solutions practical and cost-effective.

As Head of Customer Services for a busy housing developer, my biggest challenge is finding contractors who communicate as well as they plumb. Aveat excels at both. Their office staff provides clear scheduling updates, and their site technicians are excellent at explaining repairs to residents. They handle everything from minor snags to emergency leaks with total professionalism. I cannot recommend them highly enough for any developer prioritising aftercare quality.

I had the pleasure of working with Aveat on a Cat-A refurbishment in Fitzrovia, just off Hanover Square. The design had its complications, including the installation of a hybrid VRF system within a raised access floor void and additional capital plant on an already heavily congested roof. Aveat’s team were proactive and attentive throughout the programme, handling all elements of the project professionally and promptly. I am looking forward to working with them again.
