Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Active incorporated business
TSL Heating & Plumbing is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 28 years on the register also points to an established business rather than a brand-new one.

Replace back boiler with modern combi-boiler
Our old Baxi boiler had seen better days and needed replacing. We also wanted to get rid of the fire place and put the new boiler in the airing cupboard, replacing the hot water tank that was no longer required with a combi boiler. TSL were selected as they were trusted traders and on the Worcester Bosch approved list. They came along and listened to our requirements and did not try to sell us extras. The quotation was reasonable and hence accepted. On the appointed day at the appointed hour Gareth and his apprentice arrived and started. It is a messy business and it does involve every room in the house. However they minimised the mess with appropriate protection and were very good at clearing up after themselves. They explained every step and finished on time, even with the inclement weather causing roof problems. I would not hesitate to recommend them.

The engineers were great - neat and tidy, professional all week. Worked quickly, said the job was going to take all week and finished within four days. Would have them back any time.
